Extension of expiration dates for several body system listings. Final rule
Abstract:
We are extending the expiration dates of the following body systems in the Listing of Impairments (listings) in our regulations: Growth Impairment, Musculoskeletal System, Respiratory System, Cardiovascular System, Digestive System, Skin Disorders, and Neurological. We are making no other revisions to these body systems in this final rule. This extension will ensure that we continue to have the criteria we need to evaluate impairments in the affected body systems at step three of the sequential evaluation processes for initial claims and continuing disability reviews.
