D33.2 — Benign neoplasm of brain, unspecified
Is D33.2 billable?
Yes, but D33.2 is an unspecified code. D33.2 is a valid, billable ICD-10-CM code for encounters from October 1, 2026 through September 30, 2027. However, D33.2 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 D33.2 — the more specific alternatives are listed below.
