A bill to amend titles II and XVI of the Social Security Act to clarify the primary role of findings of medical severity in the disability determination process and to define the conditions on which claims may be denied solely on the basis of lack of medical severity.

Amends titles II (Old Age, Survivors and Disability Insurance) and XVI (Supplemental Security Income) of the Social Security Act to provide that the severity of an individual's physical or mental impairment shall be the primary basis for any determination of the individual's inability to engage in substantial gainful activity. Provides that before such impairment may constitute the basis for a finding of disability it must: (1) be medically determinable; (2) have limited one's ability to work; and (3) be expected to result in death or last for no less than 12 months. Frees the Secretary of Health and Human Services from conducting further inquiry where these indicia of severity are not satisfied.
