We are revising our regulations that pertain to the processing of claims for disability benefits under title II and title XVI of the Social Security Act (the Act). These revisions make the language in the rules we use under title II of the Act for making findings about medical equivalence consistent with the language in the rules that we use under title XVI of the Act. These revisions also clarify our rules about the evidence we use when we make findings about medical equivalence for adults and children. We are also updating and clarifying our rules that explain the Listing of Impairments (the listings) and how your impairment(s) can meet a listing.
