Whether the Social Security Act authorizes the Secretary to deny a disability-benefits claim at step two when the claimant lacks an impairment or combination of impairments that significantly limits basic work activities, without considering age, education, and work experience.
Holding
Yes. The step-two severity regulation is facially valid and falls within the Secretary's statutory authority.
Reasoning
The Act gives the Secretary exceptionally broad authority to issue reasonable regulations governing the proof and decision of disability claims. Because Congress expressly delegated implementation authority, the Court's review asks whether the regulation exceeds statutory authority or is arbitrary and capricious. The severity regulation satisfied that deferential standard.
The statutory definition of disability requires an inability to engage in substantial gainful activity by reason of a medically determinable impairment. Step two uses the same functional premise: an impairment must significantly limit the abilities and aptitudes needed for most jobs. If an impairment does not significantly limit basic work abilities, it does not prevent substantial gainful activity within the meaning of the Act.
The Act also expressly permits the Secretary to require claimants to furnish medical and other evidence establishing disability. It was therefore reasonable to place on the claimant the threshold burden of showing a medically determinable impairment with sufficient medical severity before requiring a fuller vocational inquiry.
The history of the disability provisions supports a threshold medical-severity screen. The 1954 legislative reports stated that an impairment must have a nature and degree of severity sufficient to justify treating it as the cause of failure to obtain substantial gainful work. Soon after, the agency adopted a rule allowing medical considerations alone to support denial where the claimant had only slight abnormalities.
Section 423(d)(2)(A), which directs consideration of age, education, and work experience in deciding whether a person can perform other work, does not forbid step two. That provision restricts who may receive benefits: a claimant with a medically severe impairment must also show inability to do past work and other substantial work in the national economy. But a claimant who cannot first establish a medically severe impairment is not eligible, so vocational factors need not be considered.
The 1967 legislative history expressly contemplated a sequential inquiry: first, whether the claimant has a severe medically determinable impairment; next, whether the claimant can perform past work; and then, if necessary, whether the claimant can do other work in light of vocational factors. This sequence supported the Secretary's allocation of the burden of proof at step two to the claimant and at step five to the Secretary.
The 1984 Disability Benefits Reform Act removed any remaining doubt about the validity of an initial medical-severity determination. By requiring consideration of the combined effect of impairments in deciding whether there is a medically severe combination, Congress recognized that the Secretary could decide medical severity before considering vocational factors. The accompanying reports endorsed use of the sequential process to deny claims involving no impairment or only slight impairments that presumptively do not seriously affect work ability.
Step two also advances legitimate administrative goals. The Secretary processes millions of claims, and the screening step identifies claims in which slight medical abnormalities make disability unlikely regardless of vocational characteristics. Like the listings at step three, it promotes uniform and efficient administration; its facial validity does not resolve whether the agency applied it too harshly in particular cases.
