           NO. D-1-GN-15-005812, HONORABLE KARIN CRUMP, JUDGE PRESIDING



                            MEMORANDUM OPINION


                This is an appeal in a suit for judicial review of an administrative decision.1 The

administrative decision arose from a dispute over reimbursement for workers’ compensation

medical benefits. Appellants are insurance companies, or “certified self-insureds,” who provide

coverage under the Texas workers’ compensation system (collectively, the Carriers). Appellees

are Vista Hospital of Dallas, Vista Medical Center Hospital, and Surgery Specialty Hospitals of

America (collectively, Vista). Vista alleged systematic underpayment of claims by the Carriers


       1
           See Tex. Gov’t Code § 2001.901(a).
beginning in 2002. Vista initially claimed a “fair and reasonable” payment of 70%–100% of

their billed charges. After a 2008 regulatory change required the kind of services that Vista

rendered to be reimbursed at 200% of the Medicare allowable reimbursement going forward,

Vista revised its calculations to that amount. A panel of State Office of Administrative Hearings

(SOAH) judges issued a Decision and Order, awarding reimbursement to Vista based on its

revised calculations because SOAH determined those amounts to be “fair and reasonable.” The

trial court affirmed SOAH’s decision, and this appeal ensued.

              In nine issues, which can be grouped into three categories, the Carriers challenge

(1) alleged procedural problems with Vista’s presentation of its case before SOAH, (2) the

evidence supporting SOAH’s findings and conclusions that the Carriers’ reimbursement

calculations did not result in “fair and reasonable” reimbursement to Vista (and that Vista’s

competing calculations did), and (3) SOAH’s award of interest to Vista. We affirm.


                                       BACKGROUND

              The underlying disputes are the latest in a long-running series between Vista

and carriers of workers’ compensation policies over reimbursement for covered medical

expenses. See generally Vista Med. Ctr. Hosp. v. State Office of Risk Mgmt., No. 03-17-00352-CV,

2018 WL 3999595 (Tex. App.—Austin Aug. 22, 2018, no pet.) (mem. op.); Vista Med. Ctr. Hosp.

v. Texas Mut. Ins. Co., 416 S.W.3d 11 (Tex. App.—Austin 2013, no pet.); Vista Healthcare, Inc.

v. Texas Mut. Ins. Co., 324 S.W.3d 264 (Tex. App.—Austin 2010, pet. denied).


       Legal Framework for Medical Reimbursement

              State law requires that “health care reimbursement policies and guidelines”

govern reimbursement of health care providers who provide services to injured workers


                                               2
covered by workers’ compensation. See Tex. Lab. Code § 413.011(a); Vista Med. Ctr. Hosp.,

2018 WL 3999595, at *1. The Division of Workers’ Compensation (Division),2 housed within

the Department of Insurance, is tasked with developing the fee guidelines that govern

reimbursement for different types of medical care. See Tex. Lab. Code §§ 401.011(8) (defining

“commissioner” as “the commissioner of workers’ compensation”), 402.00111(a) (providing

that commissioner of workers’ compensation administers Division), 413.011(a) (directing

commissioner to adopt fee guidelines); Vista Med. Ctr. Hosp., 2018 WL 3999595, at *1.

               Once the Division adopts a fee guideline for a certain type of medical care,

workers’ compensation carriers must reimburse providers of that type of care in accord with the

guideline. See id. (citing Tex. Lab. Code § 413.016(b)). But if no fee guideline (or negotiated

contract) applies to a certain type of medical care, carriers must reimburse providers of that type

of care at “a fair and reasonable reimbursement amount.” 28 Tex. Admin. Code § 134.1(e)(3)

(2018) (Tex. Dep’t of Ins., Div. of Workers’ Comp., Medical Reimbursement).


       Vista and the Carriers’ Disputes Over Vista’s Bills

               Vista provided outpatient medical services to injured workers from 2002 to 2008

under policies issued by the Carriers. In the fifty-three instances underlying this appeal, Vista

billed one or more of the Carriers for these services. Vista’s original bill in each instance was on

a Uniform Bill (UB) form—the standard bill form required by the Division. See id. § 133.10(b)(2)

       2
          The disputes underlying this appeal involve health care services provided as far back
as 2002, when the Division’s predecessor agency, the Workers’ Compensation Commission,
administered the workers’ compensation system. See Vista Healthcare, Inc. v. Texas Mut. Ins.
Co., 324 S.W.3d 264, 265 n.1 (Tex. App.—Austin 2010, pet. denied). “Effective September 1,
2005, the legislature abolished the Commission and transferred its statutory responsibilities and
rules to the Division.” Id. (citing Act of May 29, 2005, 79th Leg., R.S., ch. 265, §§ 8.001(b),
.004(a), 2005 Tex. Gen. Laws 469, 607–08). We use “Division” to refer to either or both of the
predecessor agency and the current one, as the context requires.

                                                 3
(2018) (Tex. Dep’t of Ins., Div. of Workers’ Comp., Required Billing Forms/Formats). Vista

computed its billed amounts according to its usual and customary fee schedule. Vista listed on

the UBs the “procedure codes” corresponding with the services or procedures that it performed.

               The Carriers paid Vista some, but not all, of the amounts requested. Vista asked

the Carriers to reconsider and to reimburse it at 100% of the billed charges. When the Carriers

refused, Vista requested Medical Dispute Resolution before the Division. See generally 28 Tex.

Admin. Code § 133.305 (2018) (Tex. Dep’t of Ins., Div. of Workers’ Comp., MDR—General).

Before the Division, Vista contended that “fair and reasonable” reimbursement required

compensation at no less than 70% of its billed charges in each dispute.

               Ultimately, the Division determined that Vista was not entitled to any

reimbursement beyond what the Carriers had already paid. So, from 2004 to 2009, Vista sought

de novo contested case hearings before SOAH for each of the fifty-three disputes, again

contending that reimbursement at 70%–100% of its billed charges was “fair and reasonable.”

               The fifty-three disputes remained on SOAH’s docket for several years.


       Legal Developments While the Disputes Were Pending Before SOAH

               In the meantime, there were developments in the law affecting workers’

compensation reimbursement.

               In 2006, the Division promulgated Rule 134.1, which requires “fair and

reasonable” reimbursement to be, among other things, “consistent with the criteria of Labor

Code § 413.011.” See 31 Tex. Reg. 3561, 3564 (2006) (formerly codified at 28 Tex. Admin.

Code § 134.1(d)(1) (Tex. Dep’t of Ins., Div. of Workers’ Comp., Medical Reimbursement)),

renumbered to subsection 134.1(f) by 33 Tex. Reg. 364, 393 (2008).



                                                4
               Labor Code section 413.011’s “fair and reasonable” criteria expressly apply to the

Division’s creation of fee guidelines. See Tex. Lab. Code § 413.011(d) (“Fee guidelines must be

fair and reasonable . . . .”). The criteria are that fee guidelines must be “designed to ensure the

quality of medical care,” must be “designed . . . to achieve effective medical cost control,” and

“may not provide for payment of a fee in excess of the fee charged for similar treatment of an

injured individual of an equivalent standard of living and paid by that individual or by someone

acting on that individual’s behalf.” Id. In the absence of a fee guideline for a certain type of

medical care, that care must be reimbursed at “fair and reasonable” rates.

               Following promulgation of Rule 134.1, Vista took the position that, for health

care services for which the Division had not yet created any fee guideline, the rule could only

require “fair and reasonable” reimbursement and could not also require that reimbursement

comply with Labor Code section 413.011 because that statute expressly addresses only fee

guidelines. See Vista Healthcare, 324 S.W.3d at 267, 269–71. Vista challenged the rule in

separate reimbursement disputes from those at issue in this appeal. The Division interpreted

Rule 134.1 as properly incorporating Labor Code section 413.011’s criteria even when no fee

guideline is in place, and, in 2010, this Court deferred to the Division’s interpretation and

rejected Vista’s challenge. See id. at 272–73.

               In 2008, the Division promulgated a new fee guideline to govern “medical

services provided in an outpatient acute care hospital on or after March 1, 2008” (the 2008

Fee Guideline). See 28 Tex. Admin. Code § 134.403(a), (e) (2018) (Tex. Dep’t of Ins., Div. of

Workers’ Comp., Hospital Facility Fee Guideline—Outpatient), adopted by 33 Tex. Reg. 400,

400–28 (2008). The Division crafted the 2008 Fee Guideline to satisfy, for outpatient-services

reimbursement, the criteria in Labor Code section 413.011(d). See 33 Tex. Reg. at 400–28.

                                                 5
               The 2008 Fee Guideline uses reimbursement amounts prescribed by the federal

Centers for Medicare and Medicaid Services for certain procedure codes, instead of using any

health care provider’s usual and customary charges for those procedure codes. The guideline also

requires that outpatient facilities be reimbursed at “200 percent” of “[t]he sum of the Medicare

facility specific reimbursement amount and any applicable outlier payment amount” as provided

in “the most recently adopted and effective Medicare Outpatient Prospective Payment System

(OPPS) reimbursement formula and factors as published annually in the Federal Register.”

28 Tex. Admin. Code § 134.403(f)(1)(A) (2018) (Tex. Dep’t of Ins., Div. of Workers’ Comp.,

Hospital Facility Fee Guideline—Outpatient). The 200% figure is called a Payment Adjustment

Factor (PAF) or “200% of Medicare.” An outpatient facility’s ultimate reimbursement under the

2008 Fee Guideline is, roughly, the Medicare-prescribed amount for the services performed, plus

any outlier payment,3 times two.

               The 2008 Fee Guideline included a Preamble explaining its origin and underlying

reasoning. The Preamble explained the Division’s purpose behind promulgating the guideline;

the extensive research that informed its choices; and how the guideline meets the applicable

statutory requirements, including Labor Code section 413.011’s criteria. The Preamble also

explained why the Division’s research supported the 200% PAF. For all this, the Preamble

explains, the Division relied on data from the years preceding 2008.




       3
          In this context, an “outlier” payment is an additional payment on top of the standard
Medicare-prescribed amount for a particular procedure payable when necessary to reimburse
a hospital for “high cost and complex procedures where a very costly service could present a
hospital with significant financial loss.” See Medicare Program: Changes to the Hospital
Outpatient Prospective Payment System, 72 Fed. Reg. 66,579, 66,683 (Nov. 27, 2007).

                                                6
       Vista Changes its “Fair and Reasonable” Calculations in the Pending Disputes

               When Vista presented the fifty-three fee disputes to the Division, it calculated its

reimbursement requests based on its view that Rule 134.1 should not require it to satisfy Labor

Code section 413.011’s criteria. Then, in response to the 2008 Fee Guideline’s promulgation

and to this Court’s rejection of Vista’s position on Rule 134.1 in Vista Healthcare, Vista

changed its methodology for calculating “fair and reasonable” reimbursement in the fifty-three

disputes. Even though Vista’s underlying claims preceded the 2008 Fee Guideline change, Vista

recalculated their reimbursement requests from their initial 70%–100% of billed charges to the

Medicare-prescribed reimbursement amounts for those same procedure codes, added any

applicable outlier amounts, and applied the 200% PAF. These new calculations, Vista represents,

resulted in lower overall amounts requested for reimbursement than its original calculations did.

               Vista laid out these new calculations in “Exhibit 1” documents that it filed with

SOAH in each of the fifty-three disputes.       In November 2013, Jacquelyn Pham, the Vice

President of Business Financial Services for Dynacq Healthcare, swore to an affidavit in support

of the “Exhibit 1” documents’ new calculations. In it, she said that Vista’s use of the 200% PAF

resulted in “fair and reasonable” reimbursement. And she said that using the 2008 Fee Guideline

for the fifty-three disputes produced “fair and reasonable reimbursement amount[s] which take[]

into consideration all of the factors in the Texas Labor Code that are to be considered in the

development of fee guidelines in the adjudication of fair and reasonable reimbursement.”


       Final Hearing Before SOAH, Evidence Presented, and Result

               In April 2015 before a panel of three administrative-law judges, SOAH held its

final hearing in the fifty-three disputes. Vista’s evidence included its “Exhibit 1” documents; the



                                                7
2008 Fee Guideline (including its Preamble); and testimony from Pham, who had provided the

affidavit in support of Vista’s position.

               Pham testified about her qualifications, training, and experience to opine about

Vista’s calculation methodology. She also testified about how Vista calculated the “fair and

reasonable” reimbursement amount on each “Exhibit 1,” including applying the 200% PAF, and

that Vista and payors have been using the same method for several years.

               Vista represented that, in every dispute, its “fair and reasonable” calculations

produced lower overall reimbursement amounts than its original calculations produced. But the

Carriers were unwilling to reimburse Vista at the newly calculated amounts.

               Pham was the only witness to testify. The Carriers’ counsel cross-examined her

extensively, but the Carriers did not offer any witness of their own.

               Ultimately, the SOAH panel concluded that the Carriers should reimburse Vista at

the rates calculated under the 2008 Fee Guideline, less amounts that the Carriers had already

paid. The panel’s Decision and Order specified that the panel “derive[d] a methodology for

determining fair and reasonable reimbursement.” The Decision and Order’s fourth conclusion of

law said that “Vista met its burden of proving by a preponderance of the evidence that it had not

been reimbursed a fair and reasonable amount by the Carriers for the services provided.”

               The panel included the following findings relevant here in its Decision and Order:


       4.      The responsible Carrier reimbursed Vista . . . for the services provided to
               the injured worker in each case.

       5.      Vista requested additional reimbursement in each of the cases, and in each
               case the responsible Carrier denied the request.

        ....



                                                 8
       11.     At the time Vista provided the services at issue in each case, there was no
               applicable fee guideline.

       12.     The Division adopted [the 2008 Fee Guideline], found at 28 Texas
               Administrative Code § 134.403, effective March 1, 2008.

       13.     The [2008 Fee Guideline] was adopted in order to provide fair and
               reasonable reimbursement for hospital outpatient services.

       14.     The [2008 Fee Guideline] is based on nationally-recognized studies,
               including data from other state systems, and research conducted by the
               federal Centers for Medicare and Medicaid Services (CMS).

       15.     Pursuant to the [2008 Fee Guideline], the Division adopted a Payment
               Adjustment Factor (PAF) for outpatient hospital fees of 200%, effective
               March 1, 2008.

       16.     The [2008 Fee Guideline] methodology provides a reliable method for
               calculating fair and reasonable reimbursement for the services at issue.


The Decision and Order also awarded Vista all interest as required by law.


       Proceedings in the Trial Court

               The Carriers then filed this suit, seeking judicial review of the Decision and

Order. See Tex. Lab. Code §§ 413.031(k), (k-1), .0312(a), (e) (providing for contested case

hearings of medical fee disputes before SOAH and for judicial review for “[a] party who has

exhausted all administrative remedies . . . and who is aggrieved by a final decision of the division

or [SOAH]”). The Carriers sought reversal under Texas’s Administrative Procedure Act (APA).

See generally Tex. Gov’t Code §§ 2001.001–.903. Ultimately, the trial court affirmed the Decision

and Order and rendered judgment against the Carriers for the amounts that SOAH had ordered to

be paid. The Carriers now appeal that judgment.




                                                 9
                                      STANDARD OF REVIEW

                  The Carriers ask that we reverse the district court’s judgment affirming SOAH’s

final reimbursement decision. The Carriers sought judicial review of that decision under the

APA. See generally id.; see also Tex. Lab. Code § 413.031(k), (k-1) (providing for judicial

review under APA after aggrieved party has exhausted all administrative remedies, including at

contested case hearing).       The Carriers’ appellate issues implicate the Act’s provisions for

“substantial evidence” review. See Tex. Gov’t Code § 2001.174; Tex. Lab. Code § 410.255.

Under those provisions, we must “reverse or remand the case for further proceedings if,” and

only if,


           substantial rights of the appellant have been prejudiced because the administrative
           findings, inferences, conclusions, or decisions are:

                  (A) in violation of a constitutional or statutory provision;

                  (B) in excess of the agency’s statutory authority;

                  (C) made through unlawful procedure;

                  (D) affected by other error of law;

                  (E) not reasonably supported by substantial evidence considering the
                  reliable and probative evidence in the record as a whole; or

                  (F) arbitrary or capricious or characterized by abuse of discretion or
                  clearly unwarranted exercise of discretion.


See Tex. Gov’t Code § 2001.174(2); Vista Med. Ctr. Hosp., 2018 WL 3999595, at *2.

                  “Essentially, this is a rational-basis test to determine, as a matter of law, whether

an agency’s order finds reasonable support in the record.” Jenkins v. Crosby Indep. Sch. Dist.,

Med. Ctr., 574 S.W.3d 436, 441 (Tex. App.—Austin 2018, pet. filed). “The test is not whether

                                                    10
the agency made the correct conclusion in our view, but whether some reasonable basis exists in

the record for the agency’s action.” Jenkins, 537 S.W.3d at 149; accord Facility Ins., 574 S.W.3d

at 441. “We presume that the agency’s findings, inferences, conclusions, and decisions are

supported by substantial evidence, and the burden is on the contestant to demonstrate otherwise.”

                                           DISCUSSION

I.     Procedural Issues

               We will first address the Carriers’ procedural complaints about the case that Vista

should or should not have been allowed to present before SOAH. The Carriers raise these

complaints in their sixth and seventh appellate issues.


       A.      Alleged procedural problems stemming from Vista’s new calculation
               methodology

               In their sixth issue, the Carriers put forward three alleged procedural problems

with Vista’s case: (1) “Vista failed to timely submit to each Carrier its corrected, new bill”;

(2) “Vista failed to request reconsideration of its corrected ‘bills’” by the Carriers; and (3) “Vista

failed to submit a ‘complete’ bill.” The Carriers contend that these alleged failures mean that

SOAH’s award cannot stand because it either violated a statutory provision, was in excess of

SOAH’s authority, was made through unlawful procedure, or was arbitrary and capricious.

See Tex. Gov’t Code § 2001.174(2)(A), (B), (C), (F).


               1.      Timely submission of medical bills and claims for payment

               The Carriers rely on a statute, a former rule, and a current rule for their argument

about timely bill submission. Under the statute, “[a] health care provider shall submit a claim for


                                                 11
payment to the insurance carrier not later than the 95th day after the date on which the health

care services are provided to the injured employee.” Tex. Lab. Code § 408.027(a). Failing this

requirement “constitutes a forfeiture of the provider’s right to reimbursement for that claim for

payment.” Id.4

              Under a now-repealed rule in force during the period relevant to the underlying

disputes, a health care provider could not “submit a medical bill later than the first day of the

eleventh month after the date the services are provided.” See 25 Tex. Reg. 2139, 2146 (2000)

(formerly codified at 28 Tex. Admin. Code § 134.801(c) (Tex. Dep’t of Ins., Div. of Workers’

Comp., Submitting Medical Bills for Payment)), repealed by 31 Tex. Reg. 3560, 3560 (2006).

              And under a rule in force since 2006, a health care provider generally may not

“submit a medical bill later than the 95th day after the date the services are provided.” See

28 Tex. Admin. Code § 133.20(b) (2018) (Tex. Dep’t of Ins., Div. of Workers’ Comp., Medical

Bill Submission by Health Care Provider), adopted by 31 Tex. Reg. 3554, 3555 (2006), amended

by 34 Tex. Reg. 430, 432 (2009).

              The statute applies to “claim[s] for payment,” see Tex. Lab. Code § 408.027(a),

and the two rules apply to “medical bill[s],” see 28 Tex. Admin. Code § 133.20(b) (2018) (Tex.

Dep’t of Ins., Div. of Workers’ Comp., Medical Bill Submission by Health Care Provider);

25 Tex. Reg. at 2146, repealed by 31 Tex. Reg. at 3560.

              The Carriers argue that the “Exhibit 1” documents’ reimbursement calculations

under the 2008 Fee Guideline’s methodology were new “claims for payment” or new “medical

bills.” However, the Carriers’ argument misconstrues the reimbursement process. Health care


       4
          This statute became effective September 1, 2005. Act of May 29, 2005, 79th Leg.,
R.S., ch. 265, §§ 3.089, 8.020, sec. 408.027(a), 2005 Tex. Gen. Laws 469, 517, 611.

                                               12
providers submit claims for payment as a billed charge, and payors may re-price the charges

when reimbursing. A provider need not submit a new bill when it challenges the reimbursement

amount determined by a carrier, even if the alleged underpayment changes during a regulatory

proceeding. Cf. 28 Tex. Admin. Code §§ 133.250(d) (2018) (Tex. Dep’t of Ins., Div. of Workers’

Comp., Reconsideration for Payment of Medical Bills) (requiring that providers’ “request[s] for

reconsideration” to carriers contain simply (1) same information as original bill, (2) copy of

original explanation of benefits, (3) “any necessary and related documentation not submitted

with the original medical bill to support the health care provider’s position,” and (4) explanation

“that provides a rational basis to modify the previous denial or payment”), 133.250(i) (2018)

(Tex. Dep’t of Ins., Div. of Workers’ Comp., Reconsideration for Payment of Medical Bills)

(authorizing Medical Dispute Resolution for provider after carrier has denied reconsideration).

               Vista’s evidence about its calculation process is substantial evidence to support

the conclusion that its “Exhibit 1” documents’ calculations were not new “medical bills” or new

“claims for payment.” The way Vista calculated “fair and reasonable” reimbursement may have

changed, but the underlying bills, UBs, and procedure codes did not. Vista represents that its

ultimate “fair and reasonable” calculations produced less in reimbursement than its earlier

calculations had produced. Vista’s new calculations therefore do not constitute new claims for

payment or new medical bills under the statute and two rules on which the Carriers rely. Cf.

28 Tex. Admin. Code § 133.250(d), (i) (2018) (Tex. Dep’t of Ins., Div. of Workers’ Comp.,

Reconsideration for Payment of Medical Bills) (allowing providers to pursue reconsideration and

dispute resolution with new explanations but without changing underlying bills).

                2.     Reconsideration of bills

                The Carriers also challenge the “reconsideration” step in the underlying disputes.

Generally, an aggrieved provider must request reconsideration by the carrier before proceeding

to dispute resolution before the Division. See id..

                The Carriers rely on a former rule, which was in effect during the period relevant

to the underlying disputes and which provided:


       The sender of a medical bill may request medical dispute resolution in accordance
       with §133.305 of this title (relating to Medical Dispute Resolution) if the sender of
       a medical bill has requested reconsideration in accordance with this section and:

                (1) after reconsideration, the sender is still dissatisfied with the insurance
                carrier’s action on the medical bill; or

                (2) the sender has not received the insurance carrier’s response to the
                request for reconsideration by the 28th day after the date the request for
                reconsideration was sent to the insurance carrier.


25 Tex. Reg. 2128, 2131 (2000) (formerly codified at 28 Tex. Admin. Code § 133.304(m) (Tex.

Workers’ Comp. Comm’n, Medical Payments and Denials)), repealed by 31 Tex. Reg. 3543,

3544 (2006).5

                The Carriers argue that Vista “could not possibly have submitted” its new

calculations “for reconsideration, since it never submitted these corrected, new bills to each

Carrier in the first instance.” The Carriers received Vista’s new calculations while the underlying

disputes were pending before SOAH. But Vista represents—and the Carriers do not contend
       5
          The topics addressed by former Rule 133.304(m) are now addressed within current
Rule 133.240. See 31 Tex. Reg. at 3543–45, 3550, 3557–58 (codified at 28 Tex. Admin. Code
§ 133.240 (Tex. Dep’t of Ins., Div. of Workers’ Comp., Medical Payments and Denials)); see
also 39 Tex. Reg. 2102, 2103 (2014) (“28 TAC §133.304, concerning Medical Payments and
Denials[,] was repealed and re-codified as 28 TAC §133.240, concerning Medical Payments and
Denials, in the April 28, 2006, issue of the Texas Register (31 TexReg 3544), effective May 2,
2006.”). The Carriers rely only on the former rule.

                                                  14
otherwise—that, in every dispute, Vista’s “fair and reasonable” calculations under the 2008 Fee

Guideline produced lower overall reimbursement amounts than its original calculations

produced. When Vista originally requested reconsideration, then, it did so at higher amounts

than it ultimately sought before SOAH. We therefore conclude that Vista’s original, timely

reconsideration requests were effective to support proceeding to Medical Dispute Resolution

under former Rule 133.304(m). And we conclude that Vista was not required under the rule to

ask for reconsideration again at the lower amount. See 25 Tex. Reg. at 2131 (formerly codified

at 28 Tex. Admin. Code § 133.304(m) (Tex. Workers’ Comp. Comm’n, Medical Payments and

Denials)); Texas Workers’ Comp. Comm’n v. Patient Advocates of Tex., 136 S.W.3d 643, 654

(Tex. 2004) (describing former Rule 133.304(m) in only these terms: “A health care provider

that disagrees with a carrier’s determination of the reimbursement amount may initiate the

dispute resolution process.”)


               3.      “Complete” bills

               The Carriers argue that Vista’s “Exhibit 1” in each dispute was a medical bill and

that Vista therefore did not submit complete bills because the new calculation methodology

reflected in the “Exhibit 1” documents (1) was not reflected in the documents originally

submitted to the Carriers, (2 “does not include the correct billing codes from Division fee

guidelines in effect on the date of service,” and (3) “contains charges [that] have been altered

from the UBs.” The Carriers’ position, in effect, is that Vista’s bills as originally submitted were

complete but only so long as Vista stuck with the “fair and reasonable” reimbursement

calculation methodology reflected in those bills.




                                                15
               We have already concluded that the “Exhibit 1” documents were not themselves

new medical bills. And we have concluded that former Rule 133.304(m) did not require Vista to

submit to the Carriers for reconsideration its new “fair and reasonable” reimbursement

calculations when Vista’s original request for reconsideration was calculated at the higher,

charged-based amounts. The Carriers do not argue that those earlier submissions were not

complete in themselves, so we reject this third portion of their sixth issue.

               Accordingly, we overrule the Carriers’ sixth issue.


       B.      Argument about barring Vista’s new calculation methodology before SOAH

               In their seventh issue, the Carriers contend that Vista’s claims for “fair and

reasonable” reimbursement before SOAH should have been barred for failure to meet

“jurisdictional and procedural prerequisites.” The prerequisite that the Carriers contend was

unmet is Vista’s failure to have presented the same reimbursement calculations to SOAH that

it had presented to the Division. When Vista filed its challenges with the Division from 2004

to 2009, Vista sought reimbursement calculated at 70%–100% of its billed charges. But during

the final hearing before SOAH in 2015, Vista sought reimbursement calculated at 200% of the

Medicare-prescribed charges for the outpatient services that Vista performed, plus any outlier

payment, as the 2008 Fee Guideline requires.

               The Carriers consider the revised calculation methodology to be beyond “the

claims” that Vista made “at the agency level.” Not so. Beginning with the dispute process before

the Division, and continuing through the SOAH hearing, Vista has always sought reimbursement

at “fair and reasonable” rates. This Court’s 2010 opinion in Vista Healthcare clarified that




                                                 16
Rule 134.1’s incorporation of Labor Code section 413.011(d)’s “fair and reasonable” criteria to

apply to certain fee disputes was reasonable. See generally 324 S.W.3d at 269–73.

               This Court issued Vista Healthcare in 2010—after Vista initiated with the

Division the disputes underlying this appeal but before SOAH conducted its hearing in 2015.

Vista argues that, because this Court supported the Division’s application of Rule 134.1 to “fee

disputes involving ambulatory surgical centers” in Vista Healthcare, “it was clear . . . that the

same standards would be applied to the outpatient cases” underlying this appeal. The Carriers

argue similarly: they identify the Vista facilities at issue here as ones converted from ambulatory

surgical centers to outpatient facilities, and they recognize that, for the period relevant to the

underlying disputes, reimbursement to ambulatory surgical centers was required to be “fair and

reasonable” too. See 22 Tex. Reg. 6264, 6306 (1997) (formerly codified at 28 Tex. Admin. Code

§ 134.401(a)(4)), repealed by 33 Tex. Reg. 5319, 5319–21 (2008).

               In support of their argument, the Carriers rely on Johnson v. American General

Insurance Co., 464 S.W.2d 83 (Tex. 1971), and Treybig v. Home Indemnity Co., 632 S.W.2d 896

(Tex. App.—Dallas 1982, writ ref’d n.r.e.), but those cases do not advance the Carriers’ position.

In Johnson, the Supreme Court of Texas reversed an intermediate appellate court for its holding

that there was a “fatal variance” between the “claim” that an injured worker presented to the

Industrial Accident Board and the claim that he later brought in court as part of the same dispute.

See 464 S.W.2d at 83, 86–87. In court, the injured worker alleged a workplace-injury claim of

silicosis. Id. at 85–86. But earlier before the Board, the worker did not claim silicosis, due in

large part to receiving his “medical diagnosis of silicosis” only after he had filed his claim

with the Board. Id. at 85. Nevertheless, the Supreme Court said that “the Board had before it

sufficient facts and information[] to place within its jurisdiction the occupational disease of

                                                17
silicosis” and that “there [wa]s a fair and substantial identity of the claim . . . thereafter sued

upon in court.” See id. at 86–87.

               In Treybig, there was a “fatal variance” between an injured worker’s claim before

the Board and his claim in court. See 632 S.W.2d at 898–99. Before the Board, he presented

a claim for a mere “hurt hip,” even though he knew that he had been diagnosed with an

occupational disease instead of simply a one-time accidental injury. See id. at 897–99. His “hurt

hip” claim reasonably supported only a claim of accidental injury before the Board, but his

claims in court were for a full-blown occupational disease. See id.

               Assuming without deciding that Johnson and Treybig apply to medical fee

disputes under the workers’ compensation scheme and Division rules, we conclude that those

cases do not require reversal here. Vista’s “claim,” both before the Division and SOAH, was for

reimbursement at “fair and reasonable” rates. No one argues that the Division had before it

insufficient facts or information to pass upon Vista’s “fair and reasonable” fee claims. In 2015,

SOAH had before it sufficient facts and information, even though the fee calculations

were different from what the Division had addressed. Vista changed its “fair and reasonable”

calculation methodology in response to Vista Healthcare and to the 2008 Fee Guideline, but

there was nevertheless a “fair and substantial identity of the claim” that Vista advanced before

both the Division and SOAH—“fair and reasonable” fee reimbursement.

               Accordingly, we hold that some reasonable basis exists in the record for SOAH’s

decision to allow Vista to present its new calculation methodology, in light of Vista Healthcare




                                                18
and the 2008 Fee Guideline. See Jenkins, 537 S.W.3d at 149. We therefore overrule the Carriers’

seventh issue.6


II.    Substantial Evidence Issues

       A.         Evidence that the Carriers’ calculation methodology did not produce “fair and
                  reasonable” reimbursement

                  The Carriers’ first through fifth issues challenge the sufficiency of Vista’s

evidence to support SOAH’s Decision and Order. In their first issue, the Carriers contend that

Vista failed to carry its burden to prove that the Carriers’ payments to Vista did not constitute

“fair and reasonable” reimbursement. Relatedly, they argue that there was “no evidence and no

findings of fact” to support SOAH’s fourth conclusion of law—that “Vista met its burden of

proving by a preponderance of the evidence that it had not been reimbursed a fair and reasonable

amount by Carriers for the services provided.”

                  “To obtain relief from SOAH, Vista had the burden to demonstrate by a

preponderance of the evidence that [the Carriers’] reimbursement was insufficient and that

Vista’s proposed methodology would result in fair and reasonable reimbursement.” Vista Med.

Ctr. Hosp., 2018 WL 3999595, at *2; accord Vista Healthcare, 324 S.W.3d at 268. In its fourth


       6
           Our reasoning also disposes of what the Carriers call the “Constitutional Limitations”
portion of their seventh issue. In that portion, the Carriers consider Vista’s change in calculation
methodology to be “rais[ing] a new basis for its claim” before SOAH from the one it had raised
before the Division. The Carriers argue that they themselves would have been prohibited from
making a similar change. The Carriers say that “[t]here is no rational basis to allow one party to
a dispute to make changes to its claims at any time, yet prohibit the other party from ever doing
the same.” But the “basis for [Vista’s] claim” did not change from the Division to SOAH—Vista
sought “fair and reasonable” fee reimbursement in both venues. The Carriers cite no authorities
suggesting otherwise in a constitutionality context. Indeed, the Carriers recognize that “Vista did
have the right to present evidence, old or new,” before SOAH. The Carriers had the same right,
but the Carriers did not put forward testimony from any witnesses of their own. We therefore
reject the argument that the Carriers were treated unconstitutionally differently.

                                                 19
conclusion of law, SOAH concluded that Vista had carried that burden.           “Thus, we must

determine whether the record includes substantial evidence that Vista had met its burden.” Vista

Med. Ctr. Hosp., 2018 WL 3999595, at *2.

               “Substantial evidence” requires “more than a mere scintilla.” Id. (quoting Texas

Health Facilities Comm’n v. Charter Med.–Dall., Inc., 665 S.W.2d 446, 452 (Tex. 1984)). But

the evidence “actually may preponderate against the decision of the agency and nonetheless

amount to substantial evidence.” Id. (quoting Texas Health Facilities Comm’n, 665 S.W.2d

at 452). “The true test is not whether the agency reached the correct conclusion, but whether

some reasonable basis exists in the record for the action taken by the agency.” Id. (quoting

Texas Health Facilities Comm’n, 665 S.W.2d at 452). We “sustain[]” the agency’s action “if

the evidence is such that reasonable minds could have reached the conclusion that the agency

must have reached in order to justify its action.” Id. (quoting Texas Health Facilities Comm’n,

665 S.W.2d at 452).

               Vista’s evidence included (1) the 2008 Fee Guideline; (2) Vista’s calculations of

“fair and reasonable” reimbursement in accordance with Vista Healthcare and the guideline; and

(3) comparisons between the amounts produced by those calculations with the amounts that the

Carriers agreed to pay, which were lower. Vista presented evidence that the Carriers did not

reimburse them at rates that the Division considers “fair and reasonable” under the 2008 Fee

Guideline and its 200% PAF. Because the Carriers’ payments fell short of the rates produced by

the 2008 Fee Guideline, there was more than a scintilla of evidence for SOAH to conclude that

the Carriers’ payments to Vista did not result in “fair and reasonable” reimbursement.

               The Carriers respond that there are no findings of fact in SOAH’s decision to

support the conclusion that the Carriers’ payments did not result in “fair and reasonable”

                                               20
reimbursement. On the contrary, the following findings of fact in SOAH’s order support the

conclusion that the Carriers’ payments were not “fair and reasonable” because they fell short of

the amounts produced by the 2008 Fee Guideline’s methodology: Vista requested additional

reimbursement beyond what the Carriers had paid in each dispute; the Carriers refused; there was

no applicable fee guideline when Vista provided the underlying services; the 2008 Fee Guideline

was then promulgated “to provide fair and reasonable reimbursement for hospital outpatient

services” and was “based on nationally-recognized studies, including data from other state

systems, and research conducted by the federal Centers for Medicare and Medicaid Services

(CMS)”; and the guideline, including its 200% PAF, “provides a reliable method for calculating

fair and reasonable reimbursement for the services at issue.”

               We hold that SOAH had before it substantial evidence to conclude that the

Carriers’ payments to Vista did not amount to “fair and reasonable” reimbursement.

Accordingly, we overrule the Carriers’ first issue.


       B.      Evidence that Vista’s calculation methodology produced “fair and reasonable”
               reimbursement

               The Carriers argue their second, third, and fourth issues together, so we address

them together. In their second and third issues, the Carriers contend that Vista failed to carry its

alleged burdens to prove (1) that the 200% PAF produced “fair and reasonable” rates “for each

date of service in dispute” from 2002 to 2008 and (2) “that a 200% [PAF] was the only

acceptable outpatient [PAF] for dates of service” in that period. In their fourth issue, the Carriers

contend that SOAH prejudiced their substantial rights by “adopt[ing] and retrospectively

appl[ying]” the 2008 Fee Guideline “to set a single exclusive reimbursement rate for all date[s]

of service in dispute” from 2002 to 2008. The Carriers argue that the SOAH panel, as it said in

                                                 21
the Decision and Order, should not have “derive[d] a methodology for determining fair and

reasonable reimbursement.”

              Vista’s evidence on these topics includes (1) the guideline’s Preamble, which

explains in detail how the Division created the guideline, including its 200% PAF, and

(2) Pham’s testimony.

              In the Preamble, the Division explains: “In adopting PAFs . . . , the Division has

conducted extensive research to understand hospital reimbursement in the current Texas

workers’ compensation system, including: reimbursement rates, the reimbursement rates as

compared to Medicare reimbursement, and the reimbursement rates as compared to non-workers’

compensation reimbursement for hospital services.” 33 Tex. Reg. at 405. The Division also

“considered economic indicators for hospitals that are particularly relevant,” including

“[h]ospital Medicare margins and hospital market basket information.” Id.        The Preamble

summarized other information considered by the Division:


       ▪   The Division’s health-insurance consultant estimated that, in 2005,
           outpatient-services facilities were compensated on average at 186% of
           Medicare’s prescribed amount. “Reimbursement at these levels would
           generally maintain overall system costs at [calendar year] 2005 levels.” But
           the 186% average figure was the result of “one workers’ compensation payor
           [reimbursing] at a significantly lower rate than the average payor. Adjusting
           for this anomaly, reimbursement moves to approximately 211 percent of
           Medicare allowable reimbursement.”

       ▪   “[S]takeholders” of the workers’ compensation system recommended PAFs
           ranging from 100% to 266% “of Medicare for outpatient services.”

       ▪   The Division’s Compensation Research Institute concluded that “hospital
           outpatient payments per claim in Texas were lower than the 13-state median
           studied.”

       ▪   The Division adopted the 200% PAF based on all these factors.



                                              22
Id. at 405–07. Many of these considerations stemmed from the Division’s health-insurance

consultant’s review of data from 2005 and 2006. See id. at 402, 405–06.

               The 2008 Fee Guideline also relied on other data from the several years before

promulgation. The Preamble says that “the Division has based the primary components of its

analysis on [calendar year] 2005 information” from “charged and paid data” provided by

workers’ compensation carriers. Id. at 401. The Division also studied data on about “166,000

hospital outpatient billing lines” from 2005, which led to the 186% figure. Id. at 402. The

Division concluded from 2005 and 2006 surveys conducted by the Texas Hospital Association

that outpatient services had been reimbursed by workers’ compensation carriers at about 46%–

49% of the service providers’ billed charges. Id. at 403.

               In her testimony, Pham discussed her qualifications to opine about using the 2008

Fee Guideline and its 200% PAF and why Vista decided to use it. In her role, she is responsible

for “health information management,” including “coding” and “billing and collection” under her

company’s comprehensive system for tracking codes and charges. She has “a certification as a

registered health information administrator,” which “involves all aspects of the medical record

departments, which includes coding, physician deficiencies, delinquencies, [and] making sure the

department’s up to different rules and regulations pertaining to patients’ medical records.”

               Pham also testified that she participates in at least thirty hours of continuing

education every year and is “very familiar” with the Medicare claims processing manual. The

manual “defines how Medicare would pay claims based on either inpatient or outpatient”

services.   In past health-industry employment, she worked (1) as an “auditor consultant,”

comparing bill coding to underlying records; (2) as a director of health information management;

and (3) as an executive director of operations, acting as “the hub between the business office,

                                                23
case management, and Chargemaster,” which is a billing system. In all, she has “use[d] Medicare

methodologies, weights, values,” and the like for over a dozen years. SOAH accepted her “as an

expert in . . . Medicare billing and billing practices and values.”

               Pham was involved with Vista’s application of the 2008 Fee Guideline and its

200% PAF to these disputes. Pham testified about how Vista calculated the “fair and reasonable”

reimbursement amount on each “Exhibit 1”:


       Q. Well, you added modifiers that weren’t on the bill, correct?

       A. I believe based on the coding logic was [sic] that it was my belief that we
       could add modifiers, we just couldn’t recode the CPT code.


For the modifiers, Vista used the Medicare allowable reimbursement amounts associated with

the original UBs’ procedure codes, as the 2008 Fee Guideline would require. Pham testified that

Vista refined its calculations over a period of several months and that the calculations resulting

from that effort produced “fair and reasonable” reimbursement.

               As to the 200% PAF, and as in her affidavit, she opined that using the 200% PAF

resulted in “fair and reasonable” reimbursement. She noted that Vista has used the 2008 Fee

Guideline to calculate reimbursement for outpatient services for several years. She testified that

“workers’ comp. accepts that” method “as the correct way to do it” and that several carriers

reimburse Vista according to the guideline’s calculation methodology.

               The Carriers respond that Pham’s testimony is not probative evidence at all

because it is conclusory. Conclusory opinion testimony is opinion testimony that has “no basis”

or whose basis “provides no support” for the opinion given. See City of San Antonio v. Pollock,

284 S.W.3d 809, 818 (Tex. 2009); see also Cotropia v. Texas Med. Bd., No. 03-18-00232-CV,

2018 WL 4087408, at *4 (Tex. App.—Austin Aug. 28, 2018, pet. denied) (mem. op.) (reviewing

                                                  24
expert testimony offered before administrative-law judge for whether it was conclusory);

CenterPoint Energy Entex v. Railroad Comm’n of Tex., 213 S.W.3d 364, 373 (Tex. App.—

Austin 2006, no pet.) (requiring agencies to provide basis for rejecting uncontradicted,

unimpeached testimony unless testimony is conclusory).

               The Carriers argue that Pham provided no basis, or an insufficient basis, for her

opinion that the 2008 Fee Guideline’s 200% PAF could be applied to services provided from

2002 to 2008 though the Division’s order promulgating the guideline said that it would apply

from March 1, 2008, onward. But the Preamble, entered into evidence by Vista, did provide

Pham with a sufficient basis for her opinion. The Preamble’s explanation of the Division’s and

its consultants’ research from the years preceding 2008 provided a sufficient basis. Her opinions

therefore were not conclusory. See City of San Antonio, 284 S.W.3d at 818 (expert opinions with

“no basis” or “no support” are conclusory). The Carriers therefore supplied substantial evidence

to support SOAH’s acceptance of the 2008 Fee Guideline, and its 200% PAF, as producing “fair

and reasonable” rates for the services at issue. See Vista Med. Ctr. Hosp., 2018 WL 3999595,

at *2 (quoting Texas Health Facilities Comm’n, 665 S.W.2d at 452); id. at *3 (reasoning that

“rationale and evidence underlying” newly promulgated fee guideline could produce “fair and

reasonable” reimbursement even though guideline was promulgated to apply to services

post-dating those at issue). This can be true even if other evidence in the record may have

preponderated against that conclusion. See id. at *2 (quoting Texas Health Facilities Comm’n,

665 S.W.2d at 452). Accordingly, we overrule the Carriers’ second issue.7


       7
        Relatedly, the Preamble and Pham’s testimony distinguish this case from Railroad
Commission of Texas v. Lone Star Gas Co., 618 S.W.2d 121 (Tex. App.—Austin 1981, no writ),
on which the Carriers rely. There, this Court affirmed the trial court’s judgment, which set aside
a Railroad Commission order for lack of substantial evidence to support applying a
                                               25
               We also overrule the Carriers’ third issue because it misstates Vista’s burden

before SOAH. Vista needed to have shown that calculating reimbursement according to the 2008

Fee Guideline and 200% PAF resulted in “fair and reasonable” rates—not that that methodology

was the only acceptable one. See Tex. Lab. Code § 413.011(d); Rule 134.1. We have concluded

that substantial evidence supported SOAH’s ruling that Vista’s calculations produced “fair and

reasonable” reimbursement.

               As for the Carriers’ fourth issue, we do not read the Decision and Order as

categorically as the Carriers do. They argue that the panel’s decision to “derive a methodology

for determining fair and reasonable reimbursement” was not merely an effort to resolve the

disputes but was instead taking upon itself “a new mandate to fashion a methodology for all the

cases” and “to set a single exclusive reimbursement rate.” The better reading of SOAH’s action,

however, is that it was resolving the Carriers and Vista’s dispute over how to compensate Vista

at “fair and reasonable” rates under Labor Code section 413.011(d) and Rule 134.1. To do so,

the panel necessarily needed to decide whether Vista’s proposed methodology produced “fair

and reasonable” reimbursement. Accordingly, we overrule the Carriers’ fourth issue.8


discounted-cash-flow formula for calculating natural-gas rates to two towns. Id. at 122, 124–25.
The only witness before the Commission testified that a discounted-cash-flow formula should
not be used, but the Commission chose to use that formula anyway despite no affirmative
evidence to support it. Id. at 124–25. By contrast here, the Preamble’s discussion of the Division’s
review of information from before 2008 and Pham’s affirmative testimony that the 2008 Fee
Guideline produces “fair and reasonable” reimbursement for the 2002–2008 services is the kind
of affirmative evidence that the Commission in Lone Star Gas lacked.
       8
          We also reject the Carriers’ one-sentence Due Process argument. They argue that
SOAH’s use of the 2008 Fee Guideline to arrive at “fair and reasonable” reimbursement in these
disputes is a “change of precedent” that “violates the Carriers[’] Due Process rights.” They cite
Flores v. Employees Retirement System of Texas, 74 S.W.3d 532 (Tex. App.—Austin 2002, pet.
denied), in which this Court said, “when an agency adopts new policy in the course of a
contested case hearing without giving the parties pre-hearing notice, the parties may be deprived
of procedural due process. For a hearing to be meaningful, the parties must be able to present
                                                26
       C.      Evidence that Vista’s calculations were accurate

               In their fifth issue, the Carriers contend that Vista failed to “prove by a

preponderance of the evidence that each of its . . . payment calculations were true and accurate.”

The Carriers put forward several alleged inaccuracies in Vista’s calculations under the 2008 Fee

Guideline, which, according to the Carriers, undermine SOAH’s final award.

               The Carriers’ challenges, however, amount to attacks on the credibility and

weight of Vista’s evidence. In a substantial evidence review, we “may not substitute [our]

judgment for the judgment of the state agency on the weight of the evidence on questions

committed to agency discretion.” Tex. Gov’t Code § 2001.174. The agency “is the sole judge of

the weight to be accorded the testimony of each witness” and “may accept or reject in whole or

in part the testimony of the various witnesses.” Lamb Cty. Elec. Coop., Inc. v. Public Util.

Comm’n, 269 S.W.3d 260, 272 (Tex. App.—Austin 2008, pet. denied) (quoting Cities of Corpus

Christi v. Public Util. Comm’n, 188 S.W.3d 681, 695 (Tex. App.—Austin 2005, pet. denied);

Central Power & Light Co. v. Public Util. Comm’n, 36 S.W.3d 547, 561 (Tex. App.—Austin

2000, pet. denied)).

               Pham testified that Vista refined its calculations over a period of several

months and that the calculations resulting from that effort produced “fair and reasonable”

evidence on the issues to be decided.” Id. at 545 (internal citations omitted). We do not read
SOAH’s final decision as a change in policy or precedent; it is instead an effort to reach the “fair
and reasonable” conclusion mandated by Labor Code section 413.011(d) and Rule 134.1. But
even if it were a change in policy or precedent, the Carriers cannot argue any lack of a
meaningful opportunity to be heard. The hearing before SOAH took place in April 2015. In
November 2013, Pham made her affidavit, in which she testified that Vista’s calculations
according to the 2008 Fee Guideline produced “fair and reasonable reimbursement amount[s]
which take[] into consideration all of the factors in the Texas Labor Code that are to be
considered in the development of fee guidelines in the adjudication of fair and reasonable
reimbursement.” Despite over a year’s notice of Vista’s position through the affidavit, the
Carriers chose not to put forward any witnesses of their own during the SOAH hearing.

reimbursement.     Under substantial evidence review, SOAH was permitted to believe that

testimony notwithstanding the Carriers’ cross-examination of Pham about instances of allegedly

inaccurate calculations. See Tex. Gov’t Code § 2001.174; Lamb Cty. Elec. Coop., 269 S.W.3d at

272. Accordingly, we overrule the Carriers’ fifth issue.


III.    Interest Issues

                The Carriers’ eighth and ninth issues concern SOAH’s award of interest to Vista.

SOAH’s order awarded Vista all interest as required by law, and the trial court did not disturb

that ruling.

                In their eighth issue, the Carriers contend that requiring them to “pay interest for

unpaid fees and charges” was an error that prejudiced their substantial rights because “those fees

and charges were not consistent with the guidelines.” The Carriers and Vista agree that any

interest owed by the Carriers is by operation of Labor Code section 413.019(a), which provides:

“Interest on an unpaid fee or charge that is consistent with the fee guidelines accrues at the rate

provided by Section 401.023 beginning on the 60th day after the date the health care provider

submits the bill to an insurance carrier until the date the bill is paid.”

                Our conclusions above and this Court’s decision in Vista Medical Center Hospital

dispose of this issue. In that opinion, as here, (1) Vista sought reimbursement from a workers’

compensation carrier, calculated as a percentage of its billed charges; (2) the disputes went

before SOAH; and (3) the Division promulgated a new fee guideline in the meantime. See Vista

Med. Ctr. Hosp., 2018 WL 3999595, at *1–4. This Court reasoned that the reimbursement

amounts produced by the new fee guideline provided Vista “fair and reasonable” reimbursement

even though the Division promulgated the guideline to apply to services that post-dated those at



                                                   28
issue. See id. Because the new fee guideline was promulgated during the pendency of the

dispute, Vista changed its reimbursement calculations to come into line with the new guideline.

Because the reimbursement produced by the new guideline was “fair and reasonable” under both

Labor Code section 413.011 and Rule 134.1, it was also “‘consistent with the fee guidelines’

such that Vista is entitled to prejudgment interest beginning 60 days after Vista billed [the

carrier] for each claim” under Labor Code section 413.019. Id. at *4.

               Here, as noted above, we have concluded that substantial evidence supports

SOAH’s conclusion that Vista’s calculations under the 2008 Fee Guideline produced “fair

and reasonable” reimbursement. Vista’s calculations therefore were “consistent with the fee

guidelines,” as required by Labor Code section 413.019(a). See id. at *4. Accordingly, we

overrule the Carriers’ eighth issue.

               In their ninth issue, the Carriers contend that the accrual date for calculating

interest “must be the 60th day following the date of the SOAH Order or the date each Carrier

received Vista’s” calculations under the 2008 Fee Guideline. The Carriers argue that the accrual

date for calculating interest can be no earlier than the date in each dispute when they first learned

of the amounts that Vista was claiming were “fair and reasonable” under the new guideline.

               We disagree. This Court concluded the interest discussion in Vista Medical

Center Hospital by holding that Labor Code section 413.019(a) entitled Vista to interest

“beginning 60 days after Vista billed [the carrier] for each claim.” 2018 WL 3999595, at *4. The

statute says that interest is due “on an unpaid fee or charge that is consistent with the fee

guidelines.” Tex. Lab. Code § 413.019(a). As reflected in SOAH’s order, each of the claims that

are greater than zero contain unpaid charges that are consistent with the guidelines. These unpaid

charges existed as of the date the Carriers reimbursed Vista at what has now been determined to

                                                 29
be unreasonable and unfair rates. Accordingly, interest properly accrues from the date that the

Carriers made each inadequate reimbursement. Thus, we overrule the Carriers’ ninth issue.


                                       CONCLUSION

              We affirm the trial court’s judgment.
