Michael Light, Sr., first applied for disability insurance and supplemental security income (“SSI”) benefits in December 1989, and an administrative law judge (“ALJ”) denied his claim in January 1992. Light did not challenge that decision but instead filed a new application, which is at issue in this appeal, on February 8, 1993. In his 1993 application, Light claimed that he suffered from a combination of disabling mental and physical handicaps, including pain in his shoulders, arms, wrists, back, and knees, as well as attention deficit hyperactivity disorder (“ADHD”) and borderline mental retardation (his IQ is 72). According to Light, these maladies, which he contends have grown more severe since January 1992, render him disabled and unable to work. The ALJ who heard his 1993 claim concluded that Light suffers from severe physical impairments rendering him unable to resume any of his previous jobs, but that the Commissioner satisfied her burden of proving that Light’s residual functional capacity is sufficient to permit other, less strenuous work.
The ALJ denied Light’s application for benefits. The Appeals Council denied Light’s request for review. Light then appealed to the district court, which affirmed the ALJ’s decision. Light timely appealed the district court’s judgment; we have jurisdiction under 28 U.S.C. § 1291, and we reverse and remand.
DISCUSSION
Standard of Review
We review the district court’s summary judgment order de novo. Saelee v. Chater,
Scope of Review and Claimant’s Burden of Proof
Where, as here, the Commissioner denied an earlier application by the claimant on the basis that he was “not disabled,” and the denial has become final, her conclusions create a presumption that the claimant remains capable of “substantial gainful activity.” Hammock v. Bowen,
Light’s condition changed in two material respects between the initial denial in 1992 and the hearing on his 1993 claim: his carpal tunnel syndrome increased in severity (in 1993 he was unable to form a fist or to oppose his thumb, while in 1992 he had full range of motion in his wrist and fingers and four-fifths grip strength), and he was diagnosed with ADHD. Because either of these conditions could be a basis for finding disability, either independently or when aggregated with all of Light’s preexisting infirmities, he satisfied his burden of overcoming the presumption that he is capable of work.
Existence of Disability and Residual Functional Capacity
Light contests the ALJ’s finding that he does not suffer from a disability analogous to those listed in the Appendix to the relevant regulations. See 20 C.F.R. § 404, Subpt. P, App. 1 (Listing of Impairments). He contends that either the severity of his pain alone or his aggregate disfunction (i.e., his pain, his mental impairments, and his physical infirmities considered together) disables him for purposes of the regulations. See 20 C.F.R. § 404.1526. In the alternative, Light claims that the ALJ erred when he concluded that Light’s residual functional capacity is sufficient to permit him to undertake work of “limited medium exertion [e.g., assembler, packager, canner].”
A. Evidence of Potentially Disabling Ailments
Pain of sufficient severity caused by a medically diagnosed “anatomical, physiological, or psychological abnormality]” may provide the basis for determining that a claimant is disabled. 42 U.S.C. § 423(d)(5)(A); see Bunnell v. Sullivan,
The ALJ rejected Light’s pain testimony because he “found [Light’s] testimony not credible.” In weighing a claimant’s credibility, the ALJ may consider his reputation for truthfulness, inconsistencies either in his testimony or between his testimony and his conduct, his daily activities, his work record, and testimony from physicians and third parties concerning the nature, severity, and effect of the symptoms of which he complains. Smolen,
In this case, the ALJ disbelieved Light because no objective medical evidence supported Light’s testimony regarding the severity of subjective symptoms from which he suffers, particularly pain. An ALJ may not discredit a claimant’s subjective testimony on that basis. To find the claimant not credible the ALJ must rely either on reasons unrelated to the subjective testimony (e.g., reputation for dishonesty), on conflicts between his testimony and his own conduct, or on internal contradictions in that testimony.
B. ALJ’s Conclusion Regarding Light’s Residual Functional Capacity
The ALJ also erred in evaluating Light’s residual functional capacity.
1. Consideration of aggregate impairments in determining residual functionality.
In determining Light’s residual functional capacity, the ALJ must consider whether the aggregate of Light’s mental and physical impairments may so incapacitate him that he is unable to perform available work. 20 C.F.R. § 404.1523; Macri v. Chater,
The vocational expert’s testimony, upon which the ALJ relied in his opinion, responded to a hypothetical posed by the ALJ that did not include Light’s documented illiteracy and evidence of his severe concentration problems,
2. Discrepancies between findings on residual functional capacity and Dictionary of Occupational Titles.
In determining whether appropriate jobs exist for the claimant, the ALJ generally will refer to the Dictionary of Occupational Titles (“DOT”), see Terry v. Sullivan,
CONCLUSION
The judgment is REVERSED and REMANDED for further proceedings consistent with this opinion.
Notes
. Because we remand for the ALJ to reconsider the effect of Light's excess pain testimony, we do not decide whether the severity of Light’s pain symptoms or the combination of those symptoms with his other impairments renders Light disabled. Nor do we address either whether Light’s wife’s testimony should have been considered by the ALJ or whether the ALJ properly could rely on a treating physician’s mental capacity evaluation that contradicted the claimant’s family’s testimony.
. The ALJ erred when he concluded that Light’s psychological health now that he receives treatment for ADHD must he better than that described in the 1992 decision. In 1992, Light's ADHD had not been diagnosed; the 1992 opinion therefore does not consider any psychological complaints associated with ADHD. The 1993 decision should have discussed the extent to which Light continues to suffer from ADHD-related symptoms even while medicated.
