We are revising the criteria in the Listing of Impairments (the listings) that we use to evaluate claims under titles II and XVI of the Social Security Act (Act) involving endocrine disorders in adults and children. The revisions reflect our adjudicative experience, advances in medical knowledge, information from medical experts, and comments we received from the public in response to an advance notice of proposed rulemaking (ANPRM), a notice of proposed rulemaking (NPRM), and at an outreach policy conference.
