I. Factual BACKGROUND
Joan Butler is today a 50-year-old woman with a tenth-grade education and no additional training, vocational or otherwise. From 1990 through part of 1995, Butler worked as an Environmental Services Technician (EST) at Grеater Southeast Community Hospital (GSCH) in Washington, D.C.; in this capacity she performed such tasks as making beds, mopping floors and cleaning. In early August 1995 Butler suffered a severe migraine headache and was admitted to GSCH. She stayed for four days, during which time she was treated by a neurologist, Dr. William Lightfoote. His notes indicate that Butler experienced three similar “episodes” during the past five years. Joint Appendix (JA) 163. He placed her on medication (Inderal) and scheduled diagnostic tests. The results of the tests were normal and Lightfoote scheduled additional tests, including magnetic resonance imaging (MRI). On August 22,1995 Butler attempted to return to work but suffered another migraine; the following day she saw Lightfoote who counseled her to remain off-duty for the next five days.
On August 29, 1995 Lightfoote reported that while Butler’s headaches had subsided, she was experiencing “low back pain, with radiation into the lateral аspect of both legs.” Id. 209. Lightfoote noted that the pain prevented Butler from getting out of bed. He ordered an MRI of the lumbar spine, an electromyogram (EMG) and nerve conduction tests of both lower extremities. The MRI found “narrowing and degeneration at L5-S1 ... with a very small, subligamentous herniation of nuclear material to the right of midline that minimally flattens the thecal sac. Narrowing and degeneration at L4-5 ... with a diffusely bulging annulus ... [and] mild dextroscoliosis.” Id. 156. Butler suffered another migraine on September 6, 1995 and the next day Lightfoote noted that she should remain off-duty until additional medical opinions could be obtained. Lightfoote also indicated that he would obtain a second neurological opinion from Dr. Taghi Asadi.
On Lightfoote’s referral, Butler saw Dr. Alfred Pavot, who performed an electro-neurodiagnostic study. On September 11, 1995 Pavot reported that the results of the study were consistent with lumbrosaсral facet syndrome. Butler saw Asadi later that week. Asadi’s report noted that Butler had “a history of low back pain” but was referred to him regarding the “diagnosis and management of her headaches.” Id. 207. He described her headaches as having “a character of becoming cluster-like with more frequent attacks for a couple of weeks” and noted that his physical examination revealed “no limitation of the cervical spine.” Id. Asadi concluded that she suffered migraines with “aura” and started her on Elavil, as she was already “receiving the maximum dose of Inderal.” Id.
On October 17,1995 Lightfoote observed that Butler continued to suffer lower back pain and diagnosed a herniated inverter-bral disc and lubrosacral facet syndrome. He noted that when she returned to work she would “not be able to do any lifting, bending, or stooping,” “no lifting greater than 10 pounds” and that this limitation would “have to be written in her ‘return-
On November 16, 1995 Lightfoote reported that while Butler’s headaches were “subsiding,” she continued to experience “significant” pain in her lower back. Id. 187. He noted that Butler “can hardly get out of bed, without rolling over first and rolling herself out of the bed to the floor,” “has difficulty standing up” and suffers “severe pain radiating into the lower extremities.” Id. He stated that he doubted she would be able to return to her position at GSCH. On December 9, 1995 Light-foote described Butler’s condition as “migraine with visual fortification spectra, lumbar disc herniation and lumbar facet syndrome.” Id. 176. Based on this diagnosis, he concluded that Butler was capable of performing sedentary, clerical or administrative work with certain restrictions. Specifically, he noted that Butler could not sit or stand for more than one hour at a time or lift objects heavier than 10 pounds and that she should never climb, bend or stoop. On a disability form completed around the same time, Lightfoote noted these restrictions on Butler’s future work activities but characterized her prognosis as “good.” Id. 153. He further identified Butler as a candidate for rehabilitation services, job modification and vocational counseling.
On January 23, 1996 Lightfoote opined that Butler’s headaches had become infrequent and concluded that she “is now ready” to return to work in a capacity consistent with the restrictions identified in his earlier reports. Id. 204. On April 16, 1996 Lightfoote again observed that Butler’s headaches were “very infrequent” but noted that hеr lumbar spine problems persisted. Id. 203. He stated that she had a herniated disk at two levels “at least” and some days could not get out of bed. Id. He also referred her to Dr. Lavern Bentt for lumbar epidural steroid injections.
In a report dated May 6, 1996 Bentt stated that during the previous six months Butler’s back pain had progressively worsened “to the point where she cannot sit up and stand out of bed and needs to roll herself out of bed in order to avoid excruciating pain.”
Id.
148. Bentt also remarked that aside from the moderate relief provided by physical therapy “there has been nothing that [Butler] has tried so far which has improved her pain.”
Id.
Bentt noted the results of a CT myelo-gram, “which demonstrated mild anterior extradural defects of the thecal sac at L4-5 and L5-S1.”
Id.
He performed a therapeutic lumbar epidural injection and proposed a series of additional injeсtions in the event the first provided Butler “some degree of relief.”
Id.
Butler subsequently received two additional lumbar epidural injections. At the time Butler received her third epidural injection, Bentt noted that the previous two had succeeded in easing her pain; each injection provided two weeks of complete relief but the pain eventually returned, “although not to the same intensity and degree.”
Id.
132. His report also noted that her MRI and CT myelogram showed “nerve root pathology at both L4-5 and L5-S1.”
Id.
Bentt planned for Butler to return in two to three weeks for diagnostic lumbar L4-5
According to Lightfoote’s July 9, 1996 report, he completed disability forms for Butler in which he recommended that her job be modified to accommodate her back pain and headache disordеr and that she receive vocational counseling and/or retraining. On the disability form, Light-foote classified Butler’s physical impairments as “severe,” signifying that she is “incapable of minimal activity or sedentary work.” Id. 128. Although he indicated that a job modification would enable Butler to work with her impairments, he explained that Butler could not lift, bend, stoop, push or pull and characterized her prognosis for recovery as good to poor. Id. In his July 16, 1996 report Lightfoote stated that Butler should consider retirement on total disability or “cross-training with Vocational Rehabilitation, so that she can get a job that does not entail any lifting, bending, stooping or reaching.” Id. 125. In a November 3, 1996 report Lightfoote stated that Butler was “continuing in a stable situation” but needed a transcutaneous electrical nerve stimulator (TENS) unit — a small device used to produce electroanalgesia — from GSCH. 2
On Nоvember 19, 1996 Dr. James Yan, a neurologist, evaluated Butler at the request of the Disability Determinations Division of the District of Columbia Rehabilitation Services Administration (Disability Determinations Division). Yan noted that for the past three years, Butler’s “main problem” had been “severe disk disease over the lumbosacral area” but that she also was hospitalized as a result of her last migraine headache, during which she experienced “a strokelike syndrome.” Id. 106. After finding that Butler “has severe pain which causes inability to get up easily,” “cannot stand up for too long,” “cannot lift heavy objects,” and suffers “complex migraine headaches, which come on almost once every two months ... [and] compromise her performance at work,” Yan concluded that her examination was “otherwise ... basically within normal limits.” Id. 107. He also opined that Butler’s spinal disks appeared to be within “nоrmal limits.” Id. On November 18, 1996 the Disability Determinations Division referred Butler to Dr. Harry Press for a radiology study. Two days later, Press performed a lumbar spine examination which revealed a “mild” scoliosis and atherosclerosis but was “otherwise negative.” Id. 104.
From December 1996 to March 1997, Lightfoote issued his last set of reports contained in the record. On December 17, 1996 Lightfoote stated that Butler received a TENS unit for her lower back pain and that he added lithium carbonate to her prescribed medications to combat her “lingering” headache disorder. Id. 198. On March 17, 1997 Lightfoote opined that Butler continued to experience lower back pain and “pounding in the head” and again adjusted her prescription regimen. Id. 196. On the same day he stated that Butler had evidence of herniated nucleus pulposus (HNP) in her lumbar region, that an independent medical examination (IME) disclosed a possible herniated disc in the cervical region and that she had severe migraine headaches. He concluded that “at the present time[] [Butler] is 100% disabled from any gainful employment.” Id. 197.
The last report contained in the record is a residual functional capacity assessment completed on March 30, 1997 by Dr.
II. STATUTORY FRAMEWORK
To qualify for disability insurance benefits and supplemental security income under Titles II and XVI of the Act, Butler must establish that she is “disabled.” 42 U.S.C. §§ 423(a)(1)(D), 1382(a)(1). “Disability” means the “inability to engage in any substantial gainful activity by reason of any medically determinable or mental impairment which can be expected to result in death or which has lasted or can be expected to last for a continuous period of not less than 12 months.” Id. §§ 423(d)(1)(A), 1382c(a)(3)(A). With certain exceptions not relevant here, an individual is disabled “only if [her] physical or mental impairment or impairments are of such severity that [she] is not only unable to do [her] previous work but cannot, considering [her] age, education, and work experience, engagе in any other kind of substantial gainful work which exists in the national economy.” Id. §§ 423(d)(1)(A), 1382c(a)(3)(B).
The Commissioner has established a five-step sequential evaluation process for assessing a claimant’s alleged disability. See 20 C.F.R. §§ 404.1520, 416.920. The claimant carries the burden of proof on the first four steps. Id. §§ 404.1520, 416.920. First, the claimant must demonstrate that she is not presently engaged in “substantial gainful” work. Id. §§ 404.1520(b), 416.920(b). Second, a claimant must show that she has a “severe impairment” that “significantly limits [her] physical or mental ability to do basic work activities.” Id. §§ 404.1520(c), 416.920(c). Third, if the claimant suffers from an impairment that meets the duration requirement and meets or equals an impairment listed in Appendix 1 to the Commissioner’s regulations, she is deemed disabled and the inquiry is at an end. Id. §§ 404.1520(d), 416.920(d). If the claimant does not satisfy step three, the inquiry proceeds to the fourth step, which requires her to show that she suffers an impairment that renders her incapable of performing “past relevant work.” Id. §§ 404.1520(e), 416.920(e). Once a claimant has carried the burden on the first four steps, the burden shifts to the Commissioner on step five to demonstrate that the claimant is able to perform “other work” based on a consideration of her “residual functional capacity” (RFC), age, education and past work experience. Id. §§ 404.1520(f), 416.920(f). It is the ALJ’s application of this analytical sequence that prompted Butler’s appeal.
III. Prior Proceedings
Butler applied for disability insurance benefits and supplemental security income on October 10, 1996 and September 12, 1996, respectively, claiming that she had become disabled and unable to work on August 7, 1995 as the result of back pain and migraine headaches. Her applications were rejected at every stage of the administrative process. The SSA denied Butler’s claims initially and upon reconsideration. At Butler’s request, an ALJ subsequently held a hearing, after which he
Turning to step four, the ALJ determined that while Butler was incapable of performing her past relevant work as an EST, she retained the RFC “to perform sedentary work so long as she can sit or stand at her own option, where the work does not involve lifting more than four pounds or involve more than minimal stress.” JA 32. As support for his conclusion, the ALJ referenced the reports of Drs. Asadi, Press, Yan and Lightfoote. The ALJ’s explanation of hоw the medical reports supported his finding was limited to the observations that Yan’s report “noted that [Butler] could not perform stressful work or lift heavy objects but otherwise her examination was basically within normal limits” and that Lightfoote’s December 9,1995 report found Butler “capable of sedentary, clerical or administrative work but she could not sit or stand for more than one hour or ever climb, bend, or stoop.” Id.
In evaluating Butler’s allegations of pain, the ALJ concluded that her pain did not preclude her from engaging in the limited range of sedentary work of which he found her capable. He explained that “there is no evidence of any underlying conditions which could be producing pain of the intensity which she has alleged.” Id. 33. The ALJ noted that Butler had not undergone or contemplated surgery to alleviate her pain, nor had she been hospitalized, and that her medicаtion had brought her a measure of relief. He also found that the simple functions of daily living that she continued to perform— washing dishes, making her bed, laundering her clothes, using a car to shop for groceries once a week — were consistent with the residual functional capacity he assigned her. The ALJ therefore concluded that, insofar as Butler’s daily activities were consistent with his RFC assessment, her allegations of pain were “only credible to that extent.” Id.
Because the ALJ determined that Bul-ter’s RFC nevertheless prevented her from performing her past relevant work, he proceeded to the final step, which obligated the Commissioner to demonstrate the existence of a significant number of jobs in the economy that someone with Butler’s RFC could perform. The ALJ explained that at the hearing Leonard Perlman, an independent vocational expert, tеstified that someone with Butler’s RFC would be able to perform approximately 20 per cent of the 200 sedentary, “unskilled occupations administratively noticed by the Commissioner” in the Medical-Vocational guidelines. Id. Perlman offered the occupations of film development assistant, visual inspector of small items and bindery worker as examples. Because someone with Butler’s “credible limitations” was able to perform a significant number of jobs in the economy, the ALJ concluded that Butler was not disabled under the Act. Id.
The SSA Appeals Council affirmed the ALJ’s decision on January 6, 1999. Butler then petitioned for review of the Commissioner’s decision in district court under 42 U.S.C. § 405(g); she fared no better there. On August 2, 2002 the district court granted the Commissioner’s motion for affir-mance, concluding that, while the ALJ’s finding of nondisability was “certainly spare,” it rested on substantial evidence
TV. Discussion
“In a disability proceeding, the ALJ ‘has the power and the duty to investigate fully all matters in issue, and to develop the comprehensive record required for a fair determination of disability.’ ”
Simms v. Sullivan,
Butler raises four challenges to the ALJ’s decision. She claims that the ALJ failed to properly (1) account for her physical limitations in his RFC assessment; (2) weigh the opinions of her treating physician, Dr. Lightfoote; and (3) assess her allegations of pain. Because of these errors, Butler claims, the ALJ’s reliance on the vocational expert’s testimony to support his no disability decision was misplaced. The Commissioner counters that the ALJ reached his determination based upon a proper consideration of all the record evidence. The district court agreed with the Commissioner, finding that “the ALJ’s opinion makes it clear that there is substantial evidence in the record and that his opinion rests upon that evidence.” JA 18. But the substantial evidence standard requires the court to review the record itself to determine whether it substantiatеs the story the agency would have it tell. Granted, this level of review is a deferential one but it is no less thoroughgoing for being so.

A. Butler’s Residual Functional CAPACITY
Butler asserts that in assessing her RFC the ALJ failed to properly consider her inability to meet certain physical demands of work activity — namely, her inability to lift, which is an exertional limitation, as well as her inability to reach and stoop, which are both postural limitations. We agree. The ALJ’s RFC assessment bears on Butler’s ability to perform past relevant work (step four) and her ability to do “other work” (step five). 20 C.F.R. §§ 404.1520(e)-(f), 416.920(e)-(f);
id.
§§ 404.1545(a)(5)(i)-(ii), 416.945(a)(5)(i)-(ii). It is designed to determine the claimant’s uppermost ability to perform regular and continuous work-related physical and mental activities in a work environment.
Id.
§§ 404.1545(a)(1), 416.945(a)(1);

Social Security Ruling (SSR) 96-8p, As
sessing Residual Functional Capacity in Initial Claims,
Here the ALJ found that Butler’s physical impairments prevented her from performing her past relevant work but did not preclude her from engaging in a limited range of sedentary work. He concluded that Butler “retains the residual functional capacity to perform sedentary work so long as she can sit or stand at her own option, where the work does not involve lifting more than four pounds or involve more than minimal stress.”

JA 32. In so concluding, the ALJ was required to consider the nature and extent of any limit on her ability to “perform certain physical demands of work activity,” such as lifting, reaching or stooping, that affect her ability to perform past relevant or other work.
Id.
§§ 404.1545(b), 416.945(b). Social Security Ruling 96-9p gives the ALJ additional guidance regarding the erosive effect any physical limitations may have on the “unskilled sedentary occupational base”' — the occupational base to which the ALJ concluded Butler’s impairments limited her.
See
SSR 96-9p,
Determining Capability to Do Other Work
— Implications
of a Residual Functional Capacity for Less Than a Full Range of Sedentary Work,
In light of this Ruling and Statement, it is clear that to arrive at his RFC assessment for Butler, the ALJ faded to properly consider the opinion of her treating physician, Dr. Lightfoote, who repeatedly opined that she could not lift, reach or stoop.
4
The district court found, and the Commissioner agrees, that the ALJ rejected Lightfoote’s conclusion that Butler was unable to stoop by referring to the (apparently) contrary opinions of other medical experts. JA 31-32;
see, e.g., id.
104, 106-07, 207. But the other medical opinions on which the ALJ purportedly relied do not address Butler’s ability to stoop. (The ALJ cited the views of Drs. Asadi, Press and Yan;. Hall’s opinion, which did address Butler’s ability to stoop, was not сited by the ALJ.). -In his November 19, 1996 report Yan noted that Butler’s examination was “otherwise” within “normal limits,” after having stated that Butler complained that she had disk disease over her lumbo-sacral area, had severe pain which prevented her from getting up easily, could not stand for too long and could not lift heavy objects.
Id.
106-07. Yan, however, did opine that Butler’s disks appeared to be “within normal limits.”
Id.
Asadi’s report acknowledged that Butler had a history of lower back pain, but that “there is no limitation of movement of [her] cervical spine.”
Id.
185. Butler was referred to Asadi, however, only for a second opinion on the diagnosis and treatment of her
headaches.
The ALJ also noted Press’s lumbar spine examination that revealed mild scoliosis but was otherwise “negative.”
Id.
104. It is not apparent to us how these three one-time, generalized medical reports conflict with Lightfoote’s continuous, specific opinion that Butler
cannot
stoop on the job. The ALJ’s con-clusionary attempt to justify his RFC finding that Butler was capable of engaging in a limited range of sedentary work inexplicably cited Lightfoote’s opinion that Butler
The same goes for Lightfoote’s conclusions regarding Butler’s inability to lift and reach. In concluding that Butler was capable of performing work that requires lifting of no more than four pounds, the ALJ apparently relied on Butler’s testimony that she can lift a half-gallon of milk (which, according to the ALJ, weighs approximately four pounds) “with reasonable comfort.” Id. 60. In so finding, however, he failed to explain away, or even acknowledge, Lightfoote’s three specific opinions that Butler could not perform work that required any lifting. Id. 125, 128, 188. The ALJ may have discounted these opinions in view of Lightfoote’s earlier notations indicating that Butler was capable of lifting up to 10 pounds. Thе ALJ, however, did not cite these opinions at all; rather, he relied exclusively on Butler’s own testimony at the hearing. Id. 32. But the ALJ does not tell us how Butler’s occasional lifting a half-gallon of milk conflicts with Lightfoote’s opinion that Butler could not lift as part of her regular and continuous work-activity. As to Butler’s second alleged postural limitation, it appears that the ALJ ignored Lightfoote’s opinion that Butler could not perform work that requires any reaching. Id. 125. Nowhere in the ALJ’s opinion is reaching mentioned, and none of the other medical opinions he references touches on it in the least.
In sum, we cannot discern from the record the ALJ’s basis for rejecting Light-foote’s opinions regarding these limitations nor from his mere references to the other physicians’ reports. The ALJ’s reasoning is not simply “spare”' — as the district court described it — in crucial particulars it is missing. Nor did he “note[] thе contradictory evidence in the record, which record supplie[d] the reason” for his decision.
Williams v. Shalala,
The Commissioner contends that the ALJ must have interpreted Lightfoote’s opinion that Butler should never stoop to mean that she should stoop “very little” or “only occasionally.” Appellee’s Br. at 22. While this interpretation may have some intuitive appeal, the ALJ did not articulate this view in his decision
5
and Lightfoote’s multiple opinions are not easily susceptible of such an interpretation. Despite his hopeful statements regarding Butler’s capacity to perform some gainful activity, Lightfoote consistently opined that any job Butlеr performed had to accommodate her inability to stoop. JA 103, 125, 126, 176, 180, 204. The Commissioner also directs our attention to Hall’s RFC assessment, which found Butler capable of lifting 10 pounds frequently and stooping occasionally. Although Hall’s assessment conflicts with Lightfoote’s opinions, the ALJ apparently did not rely on Hall’s assessment as that assessment was not cited in the ALJ’s order.
Id.
31-32. And in view of Light-foote’s consistent opinions to the contrary, Hall’s report, without more, does not constitute substantial evidence that Butler is capable of frequently lifting 10 pounds and stooping occasionally.

We
are therefore
B. Lightfoote’s Medioal OPINIONS
Butler argues that the ALJ failed to properly evaluate Lightfoote’s medical opinions. Lightfoote’s opinions, as those of Butler’s treating physician, are entitled to “controlling weight” if they are not inconsistent with other substantial record evidence and are well-supported by medically acceptable clinical and laboratory diagnostic techniques. 20 C.F.R. §§ 404.1527(d)(2), 416.927(d)(2). Indeed “when all of the factors are satisfied! 1
7
the adjudicator must adopt a treating source’s medical opinion irrespective of any finding he or she would have made in the absence of the medical opinion.” SSR 96-2p,
Giving Controlling Weight to Treating Source Medical Opinions,
We have a “treating physician rule” of our own. “Because a claimant’s treating physicians have great familiarity with [her] condition, their reports must be accordеd substantial weight.”
Williams,
Relying on our decision in
Williams,
the Commissioner argues that the ALJ’s acknowledgment of contrary evidence alone supplies an adequate basis for his decision. This case is not analogous to
Williams,
however, because the ALJ here did
not
acknowledge the contradictory evidence in the record, “which record suppliefd] the reason” for rejecting the treating physician’s opinion.
Butler asserts that the ALJ failed to properly assess her credibility in rejecting her claim that she suffers disabling back pain.
8
We conclude that the ALJ’s analysis here suffers from the same shortcoming that undermined his RFC assessment and rejection of Lightfoote’s opinions; namely, he did not properly consider Butler’s physical limitations. The applicable regulations prescribe a two-step process to determine whether a claimant suffers from symptoms (including pain) that affect her ability to perform basic work activities. 20 C.F.R. §§ 404.1529, 416.929. First, the claimant must adduce “medical signs or laboratory” findings evidencing a “medically determinable impairment that could reasonably be expected to produce” the alleged pain.
Id.
§§ 404.1529(a)-(b), 416.929(a)-(b);
see also
42 U.S.C. §§ 423(a)(5)(A), 1382(H)(i). The objective evidence must confirm the existence of an impairment “reasonably expected to produce,” 20 C.F.R. §§ 404.1529(b), 416.929(b), “the actual pain, in the amount and degree, alleged by the claimant.”
Craig,
The latter evaluation entails not only the claimant’s statements about her pain but also “all the available evidence,” including the claimant’s medical history, medical signs and laboratory findings; objective medical evidence of pain; the medical opinions of the claimant’s treating physician; and any other evidence that bears on the severity of the pain.
Id.
§§ 404.1529(c)(l)-(3), 416.929(c)(l)-(3);
Craig,
In considering the extent to which the claimant’s pain interferes with her capacity to engage in basic work activities, the regulations provide that the ALJ evaluates the claimant’s “statement in relation to the objective medical evidence and other evidence,”
id.
§§ 404.1529(c)(4), 416.929(c)(4), including “whether there are any inconsistencies in the evidence and the extent to which there are any conflicts between your statements and the rest of the evidence, including your medical history, the medical signs and laboratory findings, and statements by your treating or examining physician or psychologist or other persons
Social Security Ruling 96-7р supplies further guidance to the ALJ on how to evaluate pain. Once an underlying impairment that could reasonably be expected to generate the alleged pain has been established, the intensity, persistence and limiting effects of the pain must be evaluated “to determine the extent to which the symptoms affect the individual’s ability to do basic work activities.” SSR 96-7p,
Evaluation of Symptoms in Disability Claims: Assessing the Credibility of An Individual’s Statements,
Applying step one (and perhaps step two) of the analysis, the ALJ concluded that “there is no evidence of any underlying conditions which could be producing pain of the intensity which [Butler] has alleged.” JA 33. • His conclusion that “no evidence” supports her allegations once again reflects his failure to properly evaluate Lightfoote’s opinions. Moreover, Lightfoote is not alone in concluding that Butler suffers from lumbar disk hernia-tions and lumbosacral facet syndrome— diagnoses which the ALJ appears to have credited. Id. 82, 104, 116, 132. Pavot’s electroneurodiagnostic study diagnosed lumbar facet syndromе, while Press’s lumbar spine examination revealed scoliosis and atherosclerosis. Bentt also noted that Butler’s MRI and CT myelogram indicated “nerve root pathology at both L4-5 and L5-S1.” Id. 132. And even Hall’s RFC assessment lists Butler’s primary diagnosis as herniated disk disease. Id. 82. The ALJ may have thought that these diagnosed conditions could not produce the degree of pain Butler claimed to suffer but such a conclusion would be near impossible to understand without some explanation, if for no other reason than that the diagnoses are consistently accompanied by descriptions of incapacitating pain. See, e.g., id. 132, 148-49, 203. The ALJ may have rejected these evaluations by inferring from Yan’s and Press’s reports that Butler’s condition could not produce severe pain; however, he has not articulated this position and, given all of the evidence to the contrary, the record cannot do it for him.
D. VOCATIONAL EXPERT’S TESTIMONY
Butler аsserts that at step five the ALJ improperly relied on the vocational expert’s testimony to establish that she is capable of performing “other work.” We agree. If the ALJ looks to a vocational expert in assessing a claimant’s ability to do other work, the ALJ “must accurately describe the claimant’s physical impairments in any question posed to the expert.”
Simms,
We cannot say that the hypothetical question the ALJ posed to the vocational expert accurately reflected Butler’s physical limitations. The ALJ asked whether work exists in the economy for someone of “claimant’s age, education, and work background” who can perform a limited range of sedentary work. JA 68. The ALJ qualified the hypothetical by adding that the work available must allow her to sit or stand at her own option, not require her to lift more than four pounds and involve only minimal stress. The vocational expert answered affirmatively, concluding that such a person would be able to find gainful employment in 20 per cent of the 200 sedentary, unskilled occupations significantly represented in the economy that the Commissioner has “administratively noticed,” and offered as examples of such jobs, film development assistant, visual inspector and bindery worker. Id. 68-69.
In
Simms,
we found the hypothetical question the ALJ posed to the vocational expert fatally defective because it omitted significant aspects of the claimant’s condition.
For the foregoing reasons, we reverse the judgment of the district court and remand the case to that court with instructions to remand to the Commissioner for further proceedings consistent with this opinion.
So ordered.
Notes
. Although it appeared at this point that Lightfoote believed Butler capable of lifting at most 10 pounds, his later reports plainly found Butler incapable of lifting as part of any work activity. E.g., JA 125 (July 16, 1996 report), 126-28 (July 9, 1996 report and disability form).
. Shortly thereafter, on November 5, 1996, Lightfoote reported that Butler suffered an episode of migraine headaches.
. Sedentary work requires “lifting no more than 10 pounds at a time and occasionally lifting or carrying articles like docket files, ledgers, and small tools.” 20 C.F.R. §§ 404.1567(a), 416.967(a). "Although a sedentary job is defined as one which involves sitting, a certain amount of walking and standing is often necessary in cariying out job duties. Jobs are sedentary if walking and standing are required occasionally and other sedentary criteria are met.” Id. §§ 404.1567(a), 416.967(a).
. As detailed earlier, Lightfoote's myriad reports are replete with references to Butler's serious physical limitations. On October 17, 1995, Lightfoote stated that "when” Butler returns to duty, she "will not be able to do any lifting, bending or stooping.” JA 103.
