C55 — Malignant neoplasm of uterus, part unspecified
Is C55 billable?
Yes, but C55 is an unspecified code. C55 is a valid, billable ICD-10-CM code for encounters from October 1, 2026 through September 30, 2027. However, C55 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 C55.
