ICD-10 Code H47.33 – Pseudopapilledema of optic disc (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H47.33 – Pseudopapilledema of optic disc
What it is
Pseudopapilledema means the optic disc looks elevated or swollen, but the appearance is not caused by true optic nerve edema. It is often due to structural features such as optic disc drusen or a crowded disc.
Clinical signs
You may see blurred disc margins, an elevated disc contour, or a lumpy appearance on eye examination. Clinical features vary; refer to documentation, and distinguish it from true papilledema when possible.
When to use this code
Use this code when the provider documents pseudopapilledema or specifically states that optic disc swelling is not true papilledema. It may also fit when optic disc drusen or another benign anatomic cause is identified. Do not infer the diagnosis from appearance alone.
Do not use for
Do not use this code for true papilledema, optic neuritis, or other documented causes of optic disc edema. If the record only says “optic disc swelling,” check documentation.
Coding tip
Code only when the chart clearly distinguishes pseudopapilledema from papilledema or another optic nerve disorder.
