F48.8 — Other specified nonpsychotic mental disorders
Is F48.8 billable?
Yes, but F48.8 is an unspecified code. F48.8 is a valid, billable ICD-10-CM code for encounters from October 1, 2026 through September 30, 2027. However, F48.8 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 F48.8 — the more specific alternatives are listed below.
