F50.02

F50.02 — Anorexia nervosa, binge eating/purging type

Non-billable headerICD-10-CM

F50.02 is a non-billable header ICD-10-CM code for anorexia nervosa, binge eating/purging type. It cannot be billed on its own: choose one of the more specific child codes below.

Excludes1 — never code together

These conditions cannot occur together. Billing both on the same encounter is a denial.

bulimia nervosa (F50.2-)

Excludes1 inherited from the categories above F50.02

These are not written on F50.02, but they bind it: a note on a category applies to every code beneath it. Billing F50.02 with anything listed here is a denial.

Written on F50.0 — Anorexia nervosa

loss of appetite (R63.0)
psychogenic loss of appetite (F50.89)

Written on F50 — Eating disorders

anorexia NOS (R63.0)
feeding problems of newborn (P92.-)
polyphagia (R63.2)

Excludes2 inherited from the categories above F50.02

Also inherited, and the opposite of Excludes1: these conditions are not part of F50.02, but a patient can have both, so you may code both.

Written on F50 — Eating disorders

feeding difficulties (R63.3-)
feeding disorder in infancy or childhood (F98.2-)

Other codes that can never be billed with F50.02

These codes carry an Excludes1 note pointing at F50.02. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading F50.02 alone.

Risk adjustment

F50.02 does not map to an HCC and does not risk-adjust under CMS-HCC V28. That is normal — most ICD-10 codes do not. It still needs to be coded correctly; it just will not move a RAF score.

Medicare coverage

F50.02 is named in 1 Medicare coverage policy — 1 listing it as supporting medical necessity. Which of them applies to you depends on your Medicare contractor, and coverage genuinely differs by state.
