D40.10 — Neoplasm of uncertain behavior of unspecified testis
Is D40.10 billable?
Yes, but D40.10 is an unspecified code. D40.10 is a valid, billable ICD-10-CM code for encounters from October 1, 2026 through September 30, 2027. However, D40.10 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 D40.10 — the more specific alternatives are listed below.
