                             MEMORANDUM

          Baxter Healthcare Corporation is the manufacturer of

Advate, a clotting factor that is used to control and prevent

bleeding in hemophiliacs.   Baxter claims that the Department of

Health and Human Services (HHS) and the Centers for Medicare &

Medicaid Services (CMS) have violated the Administrative

Procedure Act by treating Advate as a “multiple source drug”

under 42 U.S.C. § 1395w-3a(c)(6)(C)(ii), a provision of the

Medicare statute.

          Baxter moved for a preliminary injunction, but after a

hearing on the motion, and with the consent of the parties, I

ordered that the disposition of the case on the merits would be

considered together with the pending motion, and invited the

parties to submit supplemental memoranda.   Dkt. 12.   Judgment

will now be entered in favor of the defendants.
                             Background

           Medicare Part B authorizes HHS to reimburse health care

providers for drugs they administer to enrolled Medicare

beneficiaries.   To submit a reimbursement claim, a provider logs

onto an automated system and identifies the drug it has

administered by the drug’s Healthcare Common Procedure Coding

System (HCPCS) code.    That information is sent to one of several

private contractors, who process and pay out the claim with

government funds.

           As part of its responsibilities overseeing the

reimbursement process, CMS maintains a set of national HCPCS

codes, which it revises periodically.     Declaration of Elizabeth

Richter ¶ 5.   Each HCPCS code is associated with a short phrase

that describes a category of medication -- J0290 for “Ampicillin

sodium,” for example.   See Alpha-Numeric HCPCS, available at

http://www.cms.hhs.gov/HCPCSReleaseCodeSets/.    To submit a valid

reimbursement claim, a provider must select the HCPCS code that

most closely describes the drug.   Richter Decl. ¶ 9.   If no

existing code adequately describes the drug, providers can select

a “miscellaneous/not otherwise classified” code, which serves as

a placeholder while CMS considers whether a new permanent code is

needed.   Id. ¶ 7.

           Under the Medicare Prescription Drug, Improvement, and

Modernization Act of 2003 (MMA), “multiple source drugs” and


                                - 2 -
“single source drugs or biologicals” are reimbursed at different

rates.   “Multiple source drugs” are therapeutically equivalent,

pharmaceutically equivalent, and bioequivalent to other drugs on

the market.    42 U.S.C. § 1395w-3a(c)(6)(C).   They typically fall

within the same HCPCS code as their equivalents, and their

reimbursement rate is the weighted average of the average sale

price of all drugs in that HCPCS code plus 6%.      Id. § 1395w-

3a(b)(1)(A).    “Single source drugs and biologicals” are non-

multiple source drugs and all biological products.      Id. § 1395w-

3a(c)(6)(D).    They typically have their own HCPCS code, and their

reimbursement rate is the lesser of (1) their average sale price,

or (2) their wholesale acquisition cost, plus 6%.      Id. § 1395w-

3a(b)(1)(B).

           Advate was the first anti-hemophilic factor to be made

without any added human or animal plasma proteins, eliminating

the risk of infections caused by viruses like HIV, West Nile

Virus, and the human form of Mad Cow disease.    Declaration of

Deborah K. Williams ¶ 4.    The FDA approved Baxter’s application

for Advate in July 2003, and Baxter began selling the drug on

August 20 of that year.    Id. ¶ 5; Richter Decl. ¶ 10.

           The defendants concede that Advate meets the statutory

definition of a biological.    See Dkt. 10, at 8.    But they contend

that they must treat Advate like a multiple source drug because

of a grandfather clause in the MMA, which directs the HHS


                                - 3 -
Secretary to treat single source drugs or biologicals like

multiple source drugs if they were "within the same [HCPCS] code

[as other drugs] as of October 1, 2003."     42 U.S.C. § 1395w-

3a(c)(6)(C)(ii).   The defendants assert that, as of October 1,

2003, Advate was within HCPCS code J7192 -- the code for "Factor

VII (antihemophilic factor, recombinant) per I.U.” -- along with

other anti-hemophilic products.

           Advate is the most expensive product in HCPCS code

J7192.   Williams Decl. ¶ 19.    Because the government treats

Advate like a multiple source drug, and reimburses providers at

the same rate for administering Advate as it does for

administering any of the other products in group J7192, providers

have a financial disincentive to administer Advate to Medicare

beneficiaries.   Id.   Baxter has repeatedly asked CMS to

reclassify Advate as a biological, most recently in connection

with CMS’ February 2007 review of reimbursement rates, but CMS

has refused.   Id. ¶¶ 11-17.    In December 2008, after receiving

CMS’ denial of its most recent request to reclassify Advate, id.,

Ex. 8, Baxter filed this suit.

                                Analysis

           There are two issues in dispute: whether Baxter can

seek judicial review of its claims at this time, and, if so,

whether it can show that the defendants have either

misinterpreted or misapplied 42 U.S.C. § 1395w-3a(c)(6)(C)(ii).

                                 - 4 -
Baxter prevails on the first issue, but falls short on the

second.

      A. Judicial review

           1. Standing

           The defendants contend that Baxter lacks standing

because its interest in improving Advate’s competitive position

does not fall within the zone of interests protected by 42 U.S.C.

§ 1395w-3a.

           The zone of interests test “is not meant to be

especially demanding.”     Clarke v. Sec. Indus. Ass’n, 479 U.S.

388, 399 (1987).   “Congruence of interests, rather than identity

of interests, is the benchmark; the zone of interests test serves

to exclude only those ‘parties whose interests are not consistent

with the purposes of the statute in question.’” Amgen Inc. v.

Smith, 357 F.3d 103, 109 (D.C. Cir. 2004) (quoting Ethyl Corp. v.

EPA, 306 F.3d 1144, 1148 (D.C. Cir. 2002)).

           Thus, the relevant question is not whether Baxter’s

suit is motivated by financial gain, but whether that financial

motive is aligned with the interests protected by section 1395w-

3a.   According to the conference committee report accompanying

the MMA, the reimbursement scheme in section 1395w-3a is intended

to encourage health care providers to choose between drugs based

on their relative efficacy, not their relative reimbursement


                                 - 5 -
rate.   H.R. Rep. No. 108-391, at 583-84 (Conf. Rep.) (2003).   If,

as Baxter claims, Advate is reimbursed at too low a rate, and

physicians currently have a financial incentive to administer the

other, less advanced clotting factors in HCPCS code J7192,

Baxter’s interest in this suit is at least “congruent” with those

identified by Congress.

           Admittedly, if Baxter’s challenge were successful, and

the reimbursement rate for Advate were to increase, Medicare

beneficiaries would have to pay a higher co-payment to obtain

Advate.   See 42 U.S.C. § 1395l(a)(1)(S).    While minimizing costs

for Medicare beneficiaries is surely a goal of the Medicare

statute, so too is giving beneficiaries access to the most

effective and up-to-date products.     Currently, health care

providers may not even offer beneficiaries the option of using

Advate.   If Advate’s reimbursement rate were to increase,

however, and providers had no financial disincentive to

administer it, beneficiaries would at least have the choice

between paying more for Advate and paying less for one of

Advate’s competitors -- a preferable outcome.

           2. 42 U.S.C. § 1395w-3a(g)(1)

           Next, the defendants assert that Baxter’s claims are

barred by 42 U.S.C. § 1395w-3a(g)(1), which precludes

administrative or judicial review of “determinations of payment

amounts under this section, including the assignment of National

                               - 6 -
Drug Codes1 to billing and payment codes.”   They argue that

Baxter is either challenging the determination of Advate’s

payment amount, in which case review is barred by the statute’s

first phrase, or it is challenging Advate’s assignment to HCPCS

code J7192, in which case review is barred by the statute’s

second phrase.

          Neither argument is quite right.    42 U.S.C. § 1395w-

3a(b) describes how HHS must “determine payment amounts.”      It is

a complicated process: for a single source drug or biological,

HHS must calculate the average sale price of the product (taking

into account certain exempted sales and manufacturers’

discounts), the wholesale acquisition cost of the product, and

take 106% of the lesser of the two; for a multiple source drug,

HHS must calculate the average sale price for all the drugs in

that HCPCS code, find the weighted average of those average

prices, and take 106% of the outcome.   Section 1395w-3a(g)(1)

precludes judicial and administrative review of whether HHS made

those calculations correctly.   But it does not prohibit review of

HHS’ prior determination that a product is a single source drug

or biological, or a multiple source drug.    That is the review

Baxter seeks here.




     1
       A “National Drug Code” is an 11-digit number that is used
to identify a drug’s vendor, properties, and package size. See
http://www.fda.gov/Drugs/InformationOnDrugs/ucm142438.htm.

                                - 7 -
          Similarly, Baxter is not challenging HHS’ decision to

assign Advate to HCPCS code J7192; it is only challenging HHS’

determination that Advate was “within” J7192 before October 1,

2003, the cutoff date in the MMA’s grandfather clause.   Baxter

would be content if the defendants left Advate in group J7192, as

long as they were required to treat it as a biological, rather

than as a multiple source drug.2   See Dkt. 13, at 11.

          3. 42 U.S.C. § 1395ii

          Through its incorporation of 42 U.S.C. § 405(h), 42

U.S.C. § 1395ii precludes any “action against the United States,

the [HHS Secretary], or any officer or employee thereof . . .

under [28 U.S.C. §] 1331 . . . to recover on any claim arising

under” the Medicare Act.   Section 1395ii is inapplicable,

however, when a plaintiff could not otherwise obtain



     2
       Baxter claims that it is entitled to judicial review even
if review were barred by section 1395w-3a(g)(1) because the
defendants’ actions were ultra vires, and “[j]udicial review is
favored when an agency is charged with acting beyond its
authority,” Dart v. United States, 848 F.2d 217, 221 (D.C. Cir.
1988). See Dkt. 3, at 15 n.9. That argument stretches the
definition of ultra vires action too far. An agency only acts
ultra vires when it exceeds a clear and mandatory limit on its
regulatory jurisdiction. See, e.g., Mitchell v. Christopher, 996
F.2d 375, 378 (D.C. Cir. 1993) (a valid ultra vires claim must
challenge “the very composition or ‘constitution’ of an
agency.”). There is no question that HHS has the authority under
the Medicare statute to determine whether a product is a single
source drug, a biological, or a multiple source drug. Whether
HHS made the correct determination about Advate is a routine
“dispute over statutory interpretation” that does not rise to the
level of an ultra vires claim. Dart, 848 F.2d at 231.

                               - 8 -
administrative review of its claims.    See Action Alliance of

Senior Citizens v. Leavitt, 483 F.3d 852, 859 (D.C. Cir. 2007).

          The defendants admit that Baxter itself could not

access HHS’ administrative review process.      See January 8, 2009

Hearing Tr., at 33.    But, citing Am. Chiropractic Ass’n, Inc. v.

Leavitt, 431 F.3d 812 (D.C. Cir. 2005), they contend that section

1395ii still bars Baxter’s claims because Baxter could find a

doctor or a hospital to present its claims for HHS adjudication.

          Leavitt does not require such an expansive reading of

section 1395ii.    In that case, a national association of

chiropractors challenged an HHS determination that authorized

reimbursement for chiropractors, medical doctors, and osteopaths

who performed a certain spinal procedure.    The association

claimed that the statute only authorized chiropractors to receive

reimbursement.    The Court of Appeals acknowledged that the

association itself could not seek administrative review of its

claims.   But because an association “speaks only on behalf of its

member[s],” and any of the association’s members could obtain

administrative review of its claims, section 1395ii was still

applicable.   Id. at 817 (citation omitted).3    Baxter is not suing



     3
       The other case defendants cite in support, Nat’l Athletic
Trainers Ass’n v. U.S. Dep’t of Health & Human Services, 455 F.3d
500 (5th Cir. 2006), also involves a national association suing
on behalf of its members, and the court employs the same logic to
bar the association’s claims.

                                - 9 -
on behalf of anyone who could seek administrative review of its

claims, and Leavitt does not require Baxter to recruit a

physician or hospital to act as its proxy in an administrative

process.   Because section 1395ii “does not apply . . . [when it]

would mean no review at all,” it is inapplicable here.     Shalala

v. Ill. Council on Long Term Care, Inc., 529 U.S. 1, 19 (2000).

           4. Final agency action

           Under the APA, Baxter may only seek review of “final

agency action.”   5 U.S.C. § 704.   “Final agency action” must meet

two criteria: “First, the action must mark the consummation of

the agency’s decisionmaking process -- it must not be of a merely

tentative or interlocutory nature.     And second, the action must

be one by which rights or obligations have been determined, or

from which legal consequences will flow.”     Bennett v. Spear, 520

U.S. 154, 177-78 (1997).

           CMS’ December 4, 2008 letter to Baxter satisfies these

requirements.   The letter rejects Baxter’s request to reclassify

three of its products, including Advate.     See Dkt. 3, Ex. 8.   CMS

offers several paragraphs of analysis in support of its decision,

and its legal conclusion is unequivocal: it “ will continue to

treat Advate . . . as [a] multiple source drug[] for payment

purposes under [Medicare] Part B.”     Id.




                              - 10 -
          Though the defendants cite three cases in which the

court found that a letter from an agency was not final action,

each is distinguishable: the CMS letter was not “purely

advisory,” Bennett, 520 U.S. at 178, or a “preliminary

determination,” Reliable Automatic Sprinkler Co. v. Consumer

Prod. Safety Comm’n, 324 F.3d 726, 731 (D.C. Cir. 2003), or

“purely informational in nature,” Indep. Equip. Dealer Ass’n v.

EPA, 372 F.3d 420, 427 (D.C. Cir. 2004).   CMS stated its legal

position firmly and finally, and Baxter has the right under the

APA to challenge that position.

     B. Merits

          To prevail, Baxter must show that the defendants have

either misinterpreted the MMA’s grandfather clause, or applied

the clause in an arbitrary or capricious manner.

          Under the familiar Chevron approach, to assess the

validity of the defendants’ interpretation of the MMA:

          [I] ask first whether “the intent of Congress
          is clear” as to “the precise question at
          issue.” If, “by employing traditional tools
          of statutory construction,” [I] determine
          that Congress’ intent is clear, “that is the
          end of the matter.” But “if the statute is
          silent or ambiguous with respect to the
          specific issue, the question for the court is
          whether the agency’s answer is based on a
          permissible construction of the statute.” If
          the agency’s reading fills a gap or defines a
          term in a reasonable way in light of the
          Legislature’s design . . . that reading [has]
          controlling weight, even if it is not the


                             - 11 -
           answer “the court would have reached if the
           question initially had arisen in a judicial
           proceeding.”

Regions Hosp. v. Shalala, 522 U.S. 448, 457 (1998) (quoting

Chevron U.S.A. Inc. v. NRDC, 467 U.S. 837, 842-43 (1984)).

           The statutory language at issue here is ambiguous.    In

its entirety, the MMA’s grandfather clause states, “[w]ith

respect to single source drugs or biologicals that are within the

same billing and payment code as of October 1, 2003, the

Secretary shall treat such single source drugs or biologicals as

if the single source drugs or biologicals were multiple source

drugs.”   42 U.S.C. § 1395w-3a(c)(6)(C)(ii).    Baxter argues that

the clause is clear, and covers only those single source drugs or

biologicals that the HHS Secretary (through CMS) placed in an

HCPCS code before the cutoff date.     See Dkt. 13, at 5.   But the

relevant phrase is “single source drugs or biologicals that are

within the same [HCPCS] code,” not single source drugs or

biologicals that are “placed” or “assigned” or “grouped” within

the same HCPCS code.   42 U.S.C. § 1395w-3a(c)(6)(C)(ii) (emphasis

added).   Reading “placed” or “assigned” or “grouped” into the

grandfather clause would not only inject words into the

provision, but also depart from the structure of the Medicare

Part B statute, which does not operate through the “assignment”

of drugs and biological products to HCPCS codes.     Instead, the

process is decentralized: health care providers submit

                              - 12 -
reimbursement claims using the HCPCS codes that they believe most

closely describe the drugs they administered.     Richter Decl. ¶ 9.

CMS occasionally issues guidance statements to resolve questions

from the public or from private contractors about the appropriate

code for a specific product, and it convenes an annual workgroup

to consider requests to modify the HCPCS code list.     Id. ¶ 5.

But, in most cases, CMS does not issue a definitive statement

that a particular drug should be billed under one HCPCS code or

another.   In the context of that somewhat organic assignment

process, the grandfather clause’s requirement that a drug fall

“within the same HCPCS code” is unclear.

           Moving to step two of the Chevron analysis then, the

defendants need only show that their interpretation of the

grandfather clause is permissible.     In its December 4, 2008

letter rejecting Baxter’s request for reclassification, CMS

explained that in considering whether a drug fell within the

scope of the grandfather clause, it looked at: (1) “the [FDA]

approval,” to determine whether the product at issue was a drug

or a biological product; (2) “therapeutic equivalents as

determined by the FDA,” to determine, if the product was a drug,

whether it was a single source drug or a multiple source drug;

(3) “the date of first sale in the United States,” to determine

whether it predated the cutoff date for the grandfather clause;

and (4) whether an existing HCPCS code “sufficiently described”


                              - 13 -
the drug.     Williams Decl., Ex. 8.   Because Advate was sold before

October 1, 2003, because HCPCS code J7192 sufficiently described

Advate’s characteristics, and because code J7192 contained other

clotting factors, CMS categorized Advate as a multiple source

drug.   Id.

            Baxter argues that Advate does not meet the defendants’

interpretation of the grandfather clause.     It notes that, before

the October 1, 2003 cutoff date, there was confusion among

contractors over whether HCPCS code J7192 “sufficiently

described” Advate.     Compare Williams Decl., Ex. 1 (suggesting

that the code for “miscellaneous/not otherwise classified” drugs,

J7199, was the appropriate code for Advate), with id., Ex. 2

(arguing that J7192 was sufficient).     The confusion was so

widespread that on August 27, 2004, CMS had to issue a “one-time

notification” to all contractors that “the payment limit that

should be used for Advate is the same payment limit that is

currently assigned to [HCPCS code] J7192.”     Id., Ex. 3.    In

Baxter’s view, given the confusion in the marketplace and the

fact that CMS did not declare its view until 2004, CMS cannot

claim that, as of October 1, 2003, it had determined that code

J7192 sufficiently described Advate.

            Baxter’s argument is flawed in two respects.     First,

CMS need not have determined before October 1, 2003 that Advate

was within code J7192; the grandfather clause only requires CMS

                                - 14 -
to determine whether, as of October 1, 2003, there was an

existing HCPCS code that sufficiently described Advate.     That

determination can occur at any point, and CMS can rethink its

decision, as Baxter hoped it would do upon receiving Baxter’s

repeated requests for reclassification.     Second, the confusion

among contractors and providers over the appropriate code for

Advate is irrelevant.   While CMS is not required to assign drugs

to specific HCPCS codes, and often lets providers and contractors

figure out the appropriate codes by themselves, it still retains

the ultimate authority to determine whether a product is

sufficiently described by an existing HCPCS code and to assign

that product to a particular code.     See 42 U.S.C. § 1395w-

3a(g)(1) (prohibiting judicial or administrative review of the

HHS Secretary’s “assignment of National Drug Codes to billing and

payment codes”).   As long as there is a basis for CMS’

determination that Advate was “sufficiently described” by code

J7192 -- and there is -- its conclusion that Advate is within the

scope of the grandfather clause is valid.4



     4
       Baxter also contends that CMS applied its interpretation
of the grandfather clause in an arbitrary and capricious manner
when it agreed to reclassify certain drugs (Synvisc, Octagam,
Gammagard, Flebogamma, and Gamunex) as single source drugs or
biologicals, but refused to reclassify Advate. Each of those
determinations was consistent with the defendants’ stated
interpretation of the grandfather clause, however: the five named
products were either first sold after October 1, 2003, or did not
share an HCPCS code with another product. See Richter Decl.
¶¶ 30-32.

                              - 15 -
            Baxter has cause to feel treated unfairly.   In 2003, it

was the first to introduce a clotting factor free of animal or

human proteins, only to have its product reimbursed at less than

its average sale price under the Medicare statute.     Meanwhile,

five years later, its competitor, Wyeth, introduced a nearly

identical clotting factor, which is reimbursed at its average

sale price because its entrance to the market postdated the

cutoff date in the MMA’s grandfather clause.    See Richter Decl.

¶¶ 26-28.    But Baxter’s quarrel is with Congress.   Unless and

until Congress modifies the language of the grandfather clause,

or eliminates it entirely, I am bound to apply the law as

written.    When I do so, and accord the defendants the deference

their interpretation is due, I cannot find that they acted

improperly.

                             Conclusion

            Although Baxter is entitled to judicial review of its

APA claims, it fails to show that the defendants’ interpretation

of the MMA is impermissible, or that the defendants have acted

arbitrarily or capriciously in their application of the MMA.

Accordingly, the accompanying order will enter judgment in favor
