F10.99 — Alcohol use, unspecified with unspecified alcohol-induced disorder
F10.99 is a billable, specific ICD-10-CM code for alcohol use, unspecified with unspecified alcohol-induced disorder. It is valid for submission on a claim.
Risk adjustment
F10.99 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.
