H47.019 — Ischemic optic neuropathy, unspecified eye
Is H47.019 billable?
Yes, but H47.019 is an unspecified code. H47.019 is a valid, billable ICD-10-CM code for encounters from October 1, 2026 through September 30, 2027.

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 H47.019 — the more specific alternatives are listed below.
