Our compilation of Title XVI of the Social Security Act, Supplemental Security Income for the Aged, Blind, and Disabled, was compiled as of January 1, 2003. Individual titles have been updated as public laws have become effective.

The SSI Regulations posted on our web site are those revised as of April 1, 2008. For changes since that date, please see our Social Security Program Rules Home Page.

For your convenience, we have identified several specific links to the SSI portions of the law and the regulations. We hope that these links will help you find the legal and regulatory references you need.

The Listing of Impairments, in our regulations, is a ranking of each impairment¹ by its effect(s) on the individual. A determination of disability depends on the severity of an impairment¹ or combination of impairments¹.

¹An impairment is a physiological disorder affecting one or more of a number of body systems or a mental or psychological disorder.

Also known as "The Blue Book," our edition of Disability Evaluation Under Social Security has been specially prepared to provide physicians and other health professionals with an understanding of how each program works and what medical information we need to help ensure sound and prompt decisions on disability claims.

The Program Operations Manual System (POMS) is a set of employee instructions on taking claims and paying benefits. Many parts use technical language which may not be familiar to the general public. However, the detailed operational steps may be useful in explaining how we apply the law and regulations in specific circumstances.
