N70.91 — Salpingitis, unspecified
Is N70.91 billable?
Yes, but N70.91 is an unspecified code. N70.91 is a valid, billable ICD-10-CM code for encounters from October 1, 2026 through September 30, 2027. However, N70.91 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 N70.91 — the more specific alternatives are listed below.
