The ICD-10-CM code F50.9 might also be used to specify conditions or terms like atypical anorexia nervosa, atypical bulimia nervosa, bulimia nervosa, eating disorder or eating disorder in remission.

Unspecified diagnosis codes like F50.9 are acceptable when clinical information is unknown or not available about a particular condition. Although a more specific code is preferable, unspecified codes should be used when such codes most accurately reflect what is known about a patient's condition. Specific diagnosis codes should not be used if not supported by the patient's medical record.
