Before LUCERO, Circuit Judge, BRORBY, Senior Circuit Judge, and
BACHARACH, Circuit Judge.


BACHARACH, Circuit Judge.


      Ms. Rebecca L. Mays appeals from a district court order affirming the Social

Security Administration’s denial of her application for disability benefits. We affirm.

I.    Background

      Ms. Mays applied for benefits, alleging a disability beginning in May 2004.

      The assessment began at step one, with the administrative law judge finding

that Ms. Mays had not engaged in substantial gainful activity from the alleged onset

date to the date that her insurance coverage ended.

      At step two of the sequential evaluation process, the administrative law judge

found a severe impairment of low back pain.

      At step three, the ALJ found that the impairments did not meet or medically

equal the regulatory “listings,” whether alone or in combination.

      In assessing the residual functional capacity at step four, the ALJ found a

residual functional capacity that allowed Ms. Mays to perform a full range of

sedentary work. In making this finding, the ALJ found that the opinion of Ms. Mays’

treating physician, Dr. Chorley, was not consistent with the objective medical

evidence. The ALJ also found at step four that Ms. Mays could not perform her past

relevant work.


                                         -2-
       But the judge determined at step five that jobs existed in the national economy

that Ms. Mays could perform. Thus, the ALJ found that Ms. Mays was not disabled.

       The Appeals Council denied her request for review, and the district court

affirmed the Social Security Administration’s decision.

II.    The Claims

       Ms. Mays raises two issues on appeal. First, she claims that the Social

Security Administration failed to provide a complete administrative record. Second,

she contends that the ALJ failed to properly analyze the medical source evidence.

III.   The Standard of Review

       “We review the Commissioner’s decision to determine whether the factual

findings are supported by substantial evidence and whether the correct legal

standards were applied.” Robinson v. Barnhart, 366 F.3d 1078, 1080 (10th Cir.

2004) (internal quotation marks omitted).

IV.    Claims Regarding the Incomplete Administrative Record

       Ms. Mays’ first claim relates to Dr. Chorley’s assessment of residual

functional capacity. Dr. Chorley changed this assessment, but the new version was

mistakenly omitted in the eventual administrative record. Ms. Mays contends that

the omission entailed a denial of due process and left the eventual findings without

substantial evidence. We reject these contentions.




                                         -3-
       A.     The Error in the Administrative Record

       During the hearing, Ms. Mays asked if she could submit a new version of the

doctor’s written report. Ms. Mays represented that the two reports were identical

with one exception. In the amended report, Dr. Chorley downgraded Ms. Mays’

ability to sit, stand, and walk.

       On page 1 of his original report, Dr. Chorley had opined that Ms. Mays could:

       ●      sit for 3 hours, stand for 2 hours, and walk for 1 hour at a time,

       ●      sit or stand for a total of 3 hours, and

       ●      walk for a total of 2 hours during an 8-hour work day.

In the amended report, Dr. Chorley stated that Ms. Mays could stand and walk for

10 to 30 minutes at a time; sit and stand for a total of 2 hours in an 8-hour work day;

and walk for a total of 1 hour.

       The ALJ stated that page 1 of Dr. Chorley’s original report was withdrawn and

the amended page 1 was substituted in its place. The amended report was handed to

the vocational expert, who was asked to assume the limitations stated there. The

vocational expert testified that according to the amended report, Ms. Mays could

stand and walk for 10 to 30 minutes at a time; sit and stand for a total of 2 hours in an

8-hour work day; and walk for a total of 1 hour. The expert added that there would

be no competitive work available to a person with the physical abilities stated in

Dr. Chorley’s amended report.




                                           -4-
         The amended page 1 of the report was not ultimately incorporated into the

administrative record. Thus, the record contains only the original version of

Dr. Chorley’s report.

         B.    The Due-Process Claim

         Ms. Mays contends that the error in the administrative record resulted in a

deprivation of due process because the ALJ and the Appeals Council could not

review an exhibit missing from the record. Without the new page, the ALJ and

Appeals Council could review only the version of Dr. Chorley’s report that had been

withdrawn. Because the error was not prejudicial, we reject Ms. Mays’ due-process

claim.

               1.     The District Court’s Reasoning

         The district court rejected Ms. Mays’ due-process claim, reasoning that the

information from the amended page 1 of Dr. Chorley’s report was in the record

through the vocational expert’s testimony. As we have noted, the vocational expert

recited the limitations from that page when he answered the ALJ’s questions. Based

on this exchange, the district court concluded that the ALJ had considered the

amended report.

         We agree with the district court that: (1) Dr. Chorley’s amended report was

presented at the hearing and its contents appeared in the administrative record

through the vocational expert’s testimony, and (2) the ALJ considered the amended

report during the hearing. But these conclusions do not fully address Ms. Mays’


                                           -5-
current claims. She argues that in the eventual written decision, the ALJ relied on the

wrong evidence (the original version of Dr. Chorley’s report).

             2.     The Social Security Administration’s Argument

      The Social Security Administration does not dispute Ms. Mays’ assertion that

the ALJ based his decision on Dr. Chorley’s original report. From that conclusion,

the agency argues that the original report was properly included in the administrative

record and that the doctor’s amended report was properly excluded. The agency

therefore contends that: (1) Ms. Mays is seeking a remand to submit new evidence,

and (2) we need not remand because Dr. Chorley’s amended report is immaterial.

See 42 U.S.C. § 405(g) (providing that new evidence must be material to justify a

remand); Cagle v. Califano, 638 F.2d 219, 221 (10th Cir. 1981) (holding that a

remand is proper when the reviewing court concludes that the “decision might

reasonably have been different” had the new evidence been considered).

      This reasoning, like the district court’s, does not fully address Ms. Mays’

current argument. Ms. Mays acknowledges that the record matches the ALJ’s

decision. But Ms. Mays contends that both are wrong because Dr. Chorley amended

his report and the ALJ purported to accept the amendment.

             3.     The Prejudice Inquiry

      Though we reject the reasoning of the district court and the Social Security

Administration, we must decide whether the error in the record deprived Ms. Mays of

due process. We conclude that no due-process violation took place because


                                         -6-
Ms. Mays has not shown a likelihood of a different result if the ALJ had addressed

Dr. Chorley’s amended report. Consequently, the due-process claim must fail.1

       “Social security hearings are subject to procedural due process

considerations.” Yount v. Barnhart, 416 F.3d 1233, 1235 (10th Cir. 2005). A due

process claim will not succeed, however, if the claimant fails to show prejudice.

See Energy W. Mining Co. v. Oliver, 555 F.3d 1211, 1219 (10th Cir. 2009). Thus,

when “a party complains about the course of administrative proceedings, that party

must demonstrate that the adjudication was infected by some prejudicial,

fundamentally unfair element.” Id. (internal quotation marks omitted); see Glass v.

Shalala, 43 F.3d 1392, 1396-97 (10th Cir. 1994) (requiring a showing of prejudice

for a due-process claim involving social-security proceedings).

      Ms. Mays contends that Dr. Chorley’s amended report would be crucial on

remand because it corrected an internal inconsistency between pages 1 and 3 of the

doctor’s original report. On page 1 of the original report, Dr. Chorley opined that

Ms. Mays could sit for 3 hours, stand for 2 hours, and walk for 1 hour. But

Dr. Chorley added on page 3 that Ms. Mays was unable to maintain a position of

comfort for more than 10 minutes. See Aplt. App., Vol. 3, at 280, 282. Ms. Mays

asserts that Dr. Chorley’s amended report eliminated this inconsistency by reducing
1
       We note that it is not clear how the amended version of Dr. Chorley’s report
came to be omitted from the administrative record. It appears that Ms. Mays was the
party responsible for ensuring that it was included. According to the hearing
transcript, she agreed to submit the replacement page electronically after the hearing.
The record does not disclose whether she did so.


                                         -7-
her abilities to stand and walk on page 1 to only 10 to 30 minutes at a time.

Therefore, she claims, the difference in the two versions is significant.

      We disagree because the ALJ did not reject Dr. Chorley’s original report based

on an internal inconsistency. Rather, the ALJ concluded that the doctor’s opinion

was not supported by the objective medical evidence. The ALJ cited Dr. Chorley’s

narrative, which involved his opinion that Ms. Mays was 100% disabled until

surgical intervention. Dr. Chorley did not alter that assessment in his amended report

when he upgraded Ms. Mays’ limitations on page 1. Therefore, Ms. Mays fails to

show a likelihood of a different result if the ALJ had considered the doctor’s greater

restrictions in his amended report. Without such a showing, we do not regard the

error in the record as prejudicial. And without prejudice, we must reject the

due-process claim.

      C.     The Claim Involving a Lack of Substantial Evidence

      Ms. Mays also argues that the mistake in the record left the decision without

substantial evidence. We disagree.

      “We have defined ‘substantial evidence’ as more than a scintilla. It is such

relevant evidence as a reasonable mind might accept as adequate to support a

conclusion.” Glass v. Shalala, 43 F.3d 1392, 1395 (10th Cir. 1994) (internal

quotation marks omitted).

      Ms. Mays asserts that the ALJ’s decision is not supported by substantial

evidence because the record is incomplete. We reject this argument for the reasons


                                          -8-
discussed above with the due-process claim. The ALJ had substantial evidence to

reasonably reject Dr. Chorley’s conclusions, and the existence of that evidence is not

undermined by the technical failure to replace one of the pages in the administrative

record.

V.     Claims Regarding the ALJ’s Evaluation of the Medical Source Evidence

       Ms. Mays contends that the ALJ also failed to properly analyze the

medical-source evidence. These contentions focus primarily on the ALJ’s rejection

of Dr. Chorley’s opinion. We reject each of the contentions.

       A.       The Required Process for Evaluating a Treating Physician’s
                Opinion

       The ALJ must follow a specific process when weighing a treating physician’s

opinion:

       An ALJ must first consider whether the opinion is well-supported by
       medically acceptable clinical and laboratory diagnostic techniques. . . .
       If the ALJ finds that the opinion is well-supported, he must then
       confirm that the opinion is consistent with other substantial evidence in
       the record.

Robinson v. Barnhart, 366 F.3d 1078, 1082 (10th Cir. 2004) (internal quotation

marks omitted). “[I]f the opinion is deficient in either of these respects, then it is not

entitled to controlling weight.” Id. And if the ALJ does not assign controlling

weight to a treating physician’s opinion, it is still entitled to deference and subject to

weighing under the relevant factors. See id.; see also 20 C.F.R. § 404.1527 (listing

the factors).



                                           -9-
      B.      The ALJ Properly Explained His Rejection of Dr. Chorley’s
              Opinion and Had Substantial Evidence for the Findings

      Dr. Chorley opined that Ms. Mays was 100% disabled until surgical

intervention. The ALJ rejected this opinion, concluding that this opinion was not

consistent with the objective medical evidence. Ms. Mays argues that the ALJ erred

by:

            failing to specify the weight assigned to Dr. Chorley’s opinion,

            relying on a 2006 MRI and a 2008 CT,

            disregarding evidence of retrolisthesis,

            referring to Ms. Mays’ comment about pain control through medication,

            failing to consider the regulatory factors,

            selectively referring to the evidence,

            using boilerplate language,

            relying on a consultative examiner’s opinion, and

            misconstruing the consultative examiner’s statements.

      The ALJ pointed to two medical tests: (1) a 2006 MRI that “revealed only

central disc protrusion at L5-S1” that “indented the thecal sac but did not clearly

result in neural encroachment,” and (2) a 2008 CT of the lumbar spine that “revealed

minimal disk bulge without spinal or neural foraminal impingement.” Aplt. App.,

Vol. 2, at 16. The ALJ also cited the report of a consultative examiner, Dr. Nodine,

who concluded that Ms. Mays “should be able to function in a work environment

which would limit physical hardship.” Id. The ALJ noted that Ms. Mays had told
                                       - 10 -
Dr. Nodine that “her pain [did] not become severe if she stay[ed] on her medication.”

Id. The ALJ ultimately held that the medical evidence and Dr. Nodine’s opinion

were consistent with Ms. Mays’ ability to perform a full range of sedentary work.

             1.     Specification of the Weight Assigned to the Opinion

      Ms. Mays argues that the ALJ did not expressly state whether he had given

Dr. Chorley’s opinion “controlling weight.” But the ALJ implicitly declined to give

the opinion controlling weight. Because we can tell from the decision that the ALJ

declined to give controlling weight to Dr. Chorley’s opinion, we will not reverse on

this ground. See Causey v. Barnhart, 109 F. App’x 375, 378 (10th Cir. 2004).2

             2.     Reliance on the 2006 MRI and 2008 CT

      In rejecting Dr. Chorley’s opinions, the ALJ could reasonably rely on the 2006

MRI and the 2008 CT. Ms. Mays questions this reliance, arguing that “foraminal

narrowing and central canal stenosis are factors for consideration only in cases of

meeting or equaling Listing § 1.04.” Aplt. Opening Br. at 24. But she does not

explain the ALJ’s inability to draw inferences about physical capability from the

MRI and CT.

             3.     Evidence of Retrolisthesis

      Ms. Mays also argues that the ALJ ignored the detection of retrolisthesis in the

2008 CT and in a 2004 MRI. For Ms. Mays, this evidence is significant because

Dr. Chorley referred to retrolisthesis in his opinion. But the ALJ did discuss the
2
      Though Causey is unpublished, it is persuasive.


                                         - 11 -
2004 MRI, noting that it revealed “mild” retrolisthesis. Aplt. App., Vol. 2 at 12;

see also id., Vol. 3 at 161. And Ms. Mays does not point to anything in the 2008 CT

report that would indicate a worsening of this condition.

             4.     Reference to Pain Control Through Medication

      Along with the 2006 MRI and 2008 CT, the ALJ cited Ms. Mays’ statement to

a doctor that medication kept her pain from becoming severe. Ms. Mays complains

about this reference, arguing that she also said that she was taking strong medications

four or more times per day. She does not explain why this omission is significant

and we will not construct an argument for her. See Murrell v. Shalala, 43 F.3d 1388,

1389 n.2 (10th Cir. 1994) (noting that “perfunctory complaints” failing “to frame and

develop an issue” are not “sufficient to invoke appellate review”); see also

Keyes-Zachary v. Astrue, 695 F.3d 1156, 1161 (10th Cir. 2012) (declining to consider

issues not adequately briefed for review).

             5.     Consideration of the Regulatory Factors

      Ms. Mays argues that the ALJ failed to weigh Dr. Chorley’s opinion based on

the relevant factors in 20 C.F.R. § 404.1527. But the ALJ listed those factors, and

the record shows that the ALJ adequately considered them. He recognized that

Dr. Chorley is Ms. Mays’ treating physician and discussed the doctor’s treatment

records going back several years. See Robinson v. Barnhart, 366 F.3d 1078, 1082

(10th Cir. 2004) (noting that the relevant factors included the nature and extent of the

treatment relationship, the length of treatment, and the frequency of examination).


                                         - 12 -
The ALJ also considered whether Dr. Chorley’s opinion was consistent with the

medical evidence. See id. (listing consistency with the record as another factor).

       A doctor’s relevant area of specialization is also pertinent. See id. In her

opening appeal brief, Ms. Mays contends that specialization is only important

because a neurosurgeon had recommended surgery. She does not point to any

opinion evidence from a neurosurgeon or explain why another physician’s area of

specialization is relevant to the ALJ’s analysis of Dr. Chorley’s opinion.3

See Oldham v. Astrue, 509 F.3d 1254, 1258 (10th Cir. 2007) (holding that the ALJ

need not expressly apply each factor in weighing a medical opinion).

       Finally, the ALJ considered other factors, including Ms. Mays’ report that her

pain does not become severe if she takes her medication. See Robinson v. Barnhart,

366 F.3d 1078, 1082 (10th Cir. 2004) (listing “other factors brought to the ALJ’s

attention”).

       Ms. Mays has not shown that the ALJ failed to consider the relevant regulatory

factors.

               6.   Selective Review of the Evidence

       She also contends that the ALJ improperly picked from the record when

assessing Dr. Chorley’s opinion.


3
       In her reply brief, Ms. Mays contends that the ALJ should have recognized
that Dr. Chorley was board certified in family medicine. But we do not address this
argument because it was raised for the first time in the reply brief. See Stump v.
Gates, 211 F.3d 527, 533 (10th Cir. 2000).


                                         - 13 -
      We have stated:

      The record must demonstrate that the ALJ considered all of the
      evidence, but an ALJ is not required to discuss every piece of evidence.
      Rather, in addition to discussing the evidence supporting his decision,
      the ALJ also must discuss the uncontroverted evidence he chooses not
      to rely upon, as well as significantly probative evidence he rejects.

Clifton v. Chater, 79 F.3d 1007, 1009-10 (10th Cir. 1996) (citation omitted).

      Ms. Mays points to evidence that she claims the ALJ failed to discuss, but for

the most part she does not say why it was significantly probative regarding

Dr. Chorley’s opinion. Again, we will not develop an argument for Ms. Mays.

See Murrell v. Shalala, 43 F.3d 1388, 1389 n.2 (10th Cir. 1994).4

      She does argue that the ALJ had to discuss evidence showing muscular

weakness in heel walking, foot drop, weak or absent toe muscle strength, positive

straight-leg raising tests, and asymmetrical deep tendon reflexes because these test

results were “of listing level importance.” Aplt. Opening Br. at 32. For this

proposition, she cites § 1.00E1 of the listings, which states that “[i]nability to walk

on the heels or toes, . . . when appropriate, may be considered evidence of significant

motor loss.” 20 C.F.R. Part 404, Subpart P, App. 1, § 1.00E1. That section further

advises that spinal examinations should include detailed descriptions of certain tests



4
       In a perfunctory manner, Ms. Mays contends that the ALJ’s determination
regarding Dr. Chorley’s opinion is not supported by substantial evidence. She asserts
that the evidence supporting the opinion overwhelms the evidence that the ALJ
actually discussed. But her contentions consist mostly of record citations without
further development.


                                          - 14 -
and observations, including straight-leg raising from the sitting and supine positions

and deep tendon reflexes.5

      Ms. Mays does not challenge the ALJ’s determination that she lacks an

impairment meeting or equaling the listings. Instead, Ms. Mays suggests that

evidence regarding a listing test is always significantly probative. She does not cite

authority for this suggestion, and none exists in our court.

      It is true that the listing tests reflected evidence of back pain. But, the ALJ

acknowledged at step two that Ms. Mays had low back pain. The ALJ simply

rejected Dr. Chorley’s conclusion that the pain was sufficiently severe to render

Ms. Mays disabled.

      In reaching this conclusion, the ALJ could draw from the same test results

relied upon by Ms. Mays. For example, Dr. Chorley’s examination showed that

Ms. Mays’ heel walking was normal, her sitting straight-leg raising was negative, and

her deep tendon reflexes were symmetrical.6 See Aplt. App., Vol. 3, at 283.


5
       Ms. Mays also notes that § 1.04A of the listings identifies a positive
straight-leg raising test as a factor weighing in favor of a disability finding.
See 20 C.F.R. Part 404, Subpart P, App. 1, § 1.04A (addressing spinal disorders).
Nonetheless, we have concluded in an unpublished decision that in itself, a positive
straight-leg raising test does not render a claimant unable to perform sedentary work.
Rhodes v. Barnhart, 117 F. App’x 622, 630 (10th Cir. 2004). This conclusion is
persuasive.
6
       Dr. Chorley did report a positive supine straight-leg raising on one side. But
Ms. Mays acknowledges that the ALJ discussed other evidence of a positive
straight-leg raising test. With this acknowledgment, Ms. Mays does not explain why
the omitted evidence would have been significantly probative.


                                         - 15 -
      The ALJ did not selectively pick from the record.

              7.    Use of Boilerplate Language

      Ms. Mays argues that the ALJ relied on improper boilerplate when he rejected

Dr. Chorley’s opinion. The ALJ mentioned the possibility “that a doctor [could]

express an opinion in an effort to assist a patient with whom he or she sympathize[d]

for one reason or another” and that “patients [could] be quite insistent and demanding

in seeking supportive notes or reports from their physicians.” Aplt. App., Vol. 2, at

15. Ms. Mays contends that an ALJ cannot reject a medical opinion based solely on

an assumption that the treating physician is biased. See Frey v. Bowen, 816 F.2d 508,

515 (10th Cir. 1987) (holding that the ALJ’s statement that a family doctor “naturally

advocates his patient’s cause” was insufficient to support rejection of a doctor’s

opinion (internal quotation marks omitted)). But the ALJ’s comments did not

constitute the sole basis for rejecting Dr. Chorley’s opinion and did not detract from

the ALJ’s further explanation.

              8.    Reliance on Dr. Nodine’s Opinion

      The Plaintiff also challenges the ALJ’s reliance on Dr. Nodine’s opinion. The

ALJ stated:

      Dr. Nodine’s physical assessment on December 28, 2005, found no
      inciting injury or distinctive pathology on exam. The claimant told
      Dr. Nodine her pain does not become severe if she stays on her
      medication. Dr. Nodine opined that claimant should be able to function
      in a work environment which would limit physical hardship.




                                         - 16 -
Aplt. App., Vol. 2, at 16. Ms. Mays contends that the ALJ improperly relied on

Dr. Nodine’s opinion that there was not an “inciting injury” and that Dr. Nodine’s

opinion was internally inconsistent. These contentions are rejected.

         Ms. Mays contends in part that Dr. Nodine’s finding of “no inciting injury” is

not supported by the record. For this contention, Ms. Mays insists that she has

regularly reported that she awoke in May 2004 with back pain one day after she had

been “brush-hogging” on a tractor. But Dr. Nodine’s comment must be read in

context. Dr. Nodine said that Ms. Mays had “denie[d] any injury,” and this statement

immediately followed her account of the cause of her back pain. Id., Vol. 3, at 176.

Thus, Dr. Nodine appeared to distinguish “injury” from the pain that Ms. Mays

experienced after engaging in physical activity. In any event, the ALJ twice noted

Ms. Mays’ assertion that her back pain was traceable to her brush-hogging activity,

and there is no indication that the ALJ disbelieved this explanation. See id., Vol. 2,

at 13.

         The Plaintiff also argues that Dr. Nodine’s opinion is internally inconsistent

because the doctor stated that he did not see “distinctive pathology,” yet he reported

that Ms. Mays demonstrated a positive seated straight-leg raising test on one side,

painful range of motion of her spine, muscle spasms, and tenderness upon palpation,

all of which she claims are distinctive pathologies. But again, Ms. Mays does not

explain why Dr. Nodine’s examination findings are inconsistent with an ability to




                                           - 17 -
function in a work environment. See Brown v. Bowen, 801 F.2d 361, 362-63

(10th Cir. 1986).

      According to the Plaintiff, the ALJ ignored Dr. Nodine’s statement that

Ms. Mays “would benefit from a radiographic workup to rule out anatomical

pathology and should avoid manual labor until this time.” Aplt. App., Vol. 3, at 178.

Ms. Mays interprets this statement as Dr. Nodine’s opinion that she “could not work

at all without further evaluation.” Aplt. Opening Br. at 29. It is Ms. Mays, however,

who misreads Dr. Nodine’s conclusion: Dr. Nodine stated only that Ms. Mays should

avoid manual labor until she underwent further tests.

      C.     The ALJ’s Alleged Failure to Discuss and Weigh the State Agency
             Medical Consultants’ Opinions Would Constitute Harmless Error

      Ms. Mays also argues that the ALJ failed to discuss agency medical

consultants’ opinions about her physical limitations. This argument is rejected.

      “It is the ALJ’s duty to give consideration to all the medical opinions in the

record. He must also discuss the weight he assigns to such opinions,” including the

opinions of state agency medical consultants. Keyes-Zachary v. Astrue, 695 F.3d

1156, 1161 (10th Cir. 2012) (citations omitted). But the need for express analysis is

weakened “[w]hen the ALJ does not need to reject or weigh evidence unfavorably in

order to determine a claimant’s RFC.” Id. at 1162. And an ALJ’s failure to weigh a

medical opinion involves harmless error if there is no inconsistency between the

opinion and the ALJ’s assessment of residual functional capacity. See id. at 1162-63.



                                        - 18 -
In that case, the claimant is not prejudiced “because giving greater weight to [the

opinion] would not have helped her.” Id. at 1163.

       For the sake of argument, we may assume that the ALJ failed to weigh the

state agency medical consultants’ opinions. Still, Ms. Mays does not identify any

resulting prejudice. She cites one consultant’s conclusions that she could only

occasionally climb, balance, stoop, kneel, crouch, and crawl. But she fails to explain

why these limitations would conflict with sedentary jobs, for “[p]ostural limitations

or restrictions related to such activities as climbing ladders, ropes, or scaffolds,

balancing, kneeling, crouching, or crawling would not usually erode the occupational

base for a full range of unskilled sedentary work significantly because those activities

are not usually required in sedentary work.” SSR 96-9p, 1996 WL 374185, at *7.

       Social Security Ruling 83-10 states that “[b]y its very nature, work performed

primarily in a seated position entails no significant stooping.” SSR 83-10, 1983 WL

31251, at *5; see SSR 85-15, 1985 WL 56857, at *7 (“If a person can stoop

occasionally . . . in order to lift objects, the sedentary and light occupational base is

virtually intact.”).

       Similarly, crouching is rarely needed for sedentary work. See SSR 83-14,

1983 WL 31254, at *2 (noting that to perform substantially all of the exertional

requirements of most sedentary jobs, a person would not need to crouch); see also

Robinson v. Sullivan, 956 F.2d 836, 841 (8th Cir. 1992) (stating that the ability to

crouch is not needed for substantially all sedentary and light jobs).


                                          - 19 -
      Like limitations on crouching, limitations on crawling, kneeling, or balancing

would generally prove inconsequential on the ability to perform sedentary jobs. See

SSR 85-15, 1985 WL 56857, at *7 (stating that an inability to kneel or crawl is “of

little significance in the broad world of work”); SSR 96-9p, 1996 WL 374185, at *7

(postural limitations on balancing would not erode the occupational base for a full

range of sedentary work).

      As a result, the agency consultants’ opinions proved inconsequential when the

ALJ limited Ms. Mays to sedentary work. In these circumstances, the alleged failure

to discuss the consultants’ opinions would constitute harmless error.

VI.   Disposition

      The judgment of the district court is affirmed.
