H93.90 — Unspecified disorder of ear, unspecified ear
Is H93.90 billable?
Yes, but H93.90 is an unspecified code. H93.90 is a valid, billable ICD-10-CM code for encounters from October 1, 2026 through September 30, 2027. However, H93.90 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 H93.90 — the more specific alternatives are listed below.
