F32.9 — Major depressive disorder, single episode, unspecified
Is F32.9 billable?
Yes, but F32.9 is an unspecified code. F32.9 is a valid, billable ICD-10-CM code for encounters from October 1, 2026 through September 30, 2027. However, F32.9 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 F32.9 — the more specific alternatives are listed below.

Excludes2 — not included here — inherited from Chapter 5
The conditions below are not part of F32.9, but a patient may have both at the same time. When documentation supports it, F32.9 and the excluded code may both be reported.
