F50.02 ICD-10-CM Code: Anorexia nervosa, binge eating/purging type

F50.02 is the ICD-10-CM diagnosis code for anorexia nervosa, binge eating/purging type. F50.02 sits in the ICD-10-CM chapter for mental, behavioral and neurodevelopmental disorders (f01-f99), within the section covering behavioral syndromes associated with physiological disturbances and physical factors (f50-f59).

Header codes like F50.02 cannot be reported on claims directly, they organize child codes that share clinical context but the actual diagnosis must be coded to the highest level of specificity supported by the documentation. Coders should look at F50.02's child codes and select the one that matches the patient's documented presentation, since payers reject header codes submitted as the primary diagnosis. For risk adjustment workflows, header codes never contribute to a Medicare Advantage member's RAF score on their own; only billable child codes that happen to map to a payment HCC affect risk-adjusted plan payments.
