ICD-10 Code H47.32 – Drusen of optic disc (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H47.32 – Drusen of optic disc
What it is
H47.32 identifies optic disc drusen, which are calcified deposits within the optic nerve head. They are often incidental findings and may be buried or visible on eye examination.
Clinical signs
Findings may include a lumpy, elevated optic disc, pseudopapilledema, or visual field defects. Clinical features vary; refer to documentation.
When to use this code
Use H47.32 when the provider documents drusen of the optic disc, whether discovered during routine exam or workup for blurred vision or visual field loss. Code it when the diagnosis is confirmed clinically or by imaging, and not merely suspected. Check documentation if the note describes optic disc swelling without clear drusen.
Do not use for
Do not use this code for true papilledema, optic neuritis, or other causes of optic nerve head swelling. If the record only says “optic disc anomaly” or “disc edema,” check documentation.
Coding tip
Confirm the provider specifically documents optic disc drusen before assigning H47.32.
