Revised medical criteria for evaluating digestive disorders. Final rule
Abstract:
We are revising the criteria in the Listing of Impairments (the listings) that we use to evaluate claims involving digestive disorders. We apply these criteria when you claim benefits based on disability under title II and title XVI of the Social Security Act (the Act). The revisions reflect advances in medical knowledge, methods of evaluating digestive disorders, treatment, and our program experience. We are also removing listings that are redundant because they only refer to other listings, and we are making other conforming changes.
