Extension of expiration dates for several body system listings. Final rule.

We are extending the expiration dates of the following body systems in the Listing of Impairments (listings) in our regulations: Cardiovascular System, Endocrine System, Growth Impairment, Hematological Disorders, Musculoskeletal System, Mental Disorders, Neurological, and Respiratory System. We are making no other revisions to these body system listings. This extension will ensure that we continue to have in the listings the criteria we need to evaluate impairments in the affected body systems at the appropriate steps of the sequential evaluation processes for initial claims and continuing disability reviews.
