ICD-10 Code H47.011 – Ischemic optic neuropathy, right eye (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H47.011 – Ischemic optic neuropathy, right eye
What it is
H47.011 identifies ischemic optic neuropathy affecting the right eye. It means the optic nerve has been injured by reduced blood flow, leading to sudden visual loss or field defects.
Clinical signs
Common findings include sudden, painless vision loss in the right eye and an afferent pupillary defect. Visual field loss and optic disc swelling may be documented; clinical features vary, so refer to documentation.
When to use this code
Use this code when the provider documents ischemic optic neuropathy limited to the right eye. It is appropriate for confirmed diagnoses in outpatient, inpatient, or consult notes. Code the documented laterality exactly as stated.
Do not use for
Do not use H47.011 for optic neuritis, retinal vascular occlusion, or unspecified optic neuropathy. If the record does not identify the right eye, check documentation before coding.
Coding tip
Always verify laterality and the exact optic nerve diagnosis in the assessment, not just the symptom of vision loss.
