ICD-10 Code H47.1 – Papilledema (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H47.1 – Papilledema
What it is
Papilledema is swelling of the optic disc caused by increased intracranial pressure. Use this code when the record specifically identifies optic disc edema from raised pressure, not a vague eye complaint.
Clinical signs
Typical findings include blurred optic disc margins on eye exam, sometimes with headache, transient visual obscurations, or decreased vision. Clinical features vary; refer to documentation.
When to use this code
Use H47.1 when the provider documents papilledema, optic disc swelling, or papillary edema due to intracranial pressure. It may appear in notes from neurology, ophthalmology, or emergency evaluations. Code it only when the diagnosis is clearly stated.
Do not use for
Do not use this code for other optic nerve disorders, nonspecific visual symptoms, or eye swelling without confirmed papilledema. Check documentation if the note says “disc edema” without a clear cause.
Coding tip
Look for the exact term “papilledema” in the assessment and confirm whether it is documented as a diagnosis, not just an exam finding.
