N60.89 — Other benign mammary dysplasias of unspecified breast
Is N60.89 billable?
Yes, but N60.89 is an unspecified code. N60.89 is a valid, billable ICD-10-CM code for encounters from October 1, 2026 through September 30, 2027. However, N60.89 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 N60.89 — the more specific alternatives are listed below.

- disorders of breast associated with childbirth (O91-O92)
