The nomenclature employed in this portion of the rating schedule is based upon the American Psychiatric Association’s Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5) (see § 4.125 for availability information). Rating agencies must be thoroughly familiar with this manual to properly implement the directives in § 4.125 through § 4.129 and to apply the general rating formula for mental disorders in § 4.130. The schedule for rating for mental disorders is set forth as follows:
| Description | Rating |
|---|---|
| 9520 Anorexia nervosa | |
| Rating Formula for Eating Disorders | |
