D35.00 — Benign neoplasm of unspecified adrenal gland
Is D35.00 billable?
Yes, but D35.00 is an unspecified code. D35.00 is a valid, billable ICD-10-CM code for encounters from October 1, 2026 through September 30, 2027. However, D35.00 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 D35.00 — the more specific alternatives are listed below.
