F10.959 — Alcohol use, unspecified with alcohol-induced psychotic disorder, unspecified
Is F10.959 billable?
Yes, but F10.959 is an unspecified code. F10.959 is a valid, billable ICD-10-CM code for encounters from October 1, 2026 through September 30, 2027. However, F10.959 is an unspecified or catch-all code. Payers apply additional scrutiny to unspecified codes and many deny them when the medical record supports a more specific option, so check the documentation before selecting F10.959 — the more specific alternatives are listed below.
