ICD-10 Code H47.12 – Papilledema associated with decreased ocular pressure (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H47.12 – Papilledema associated with decreased ocular pressure
What it is
This code identifies papilledema, which is optic disc swelling, when it is documented as associated with decreased ocular pressure. Use it only when the chart explicitly links the finding to low eye pressure.
Clinical signs
Typical findings include optic disc swelling seen on eye examination and documentation of reduced ocular pressure. Clinical features vary; refer to documentation.
When to use this code
Use H47.12 when the provider states papilledema is present and specifically associates it with decreased ocular pressure. It may also fit when the assessment documents optic disc edema with low intraocular pressure as the cause or associated condition. Check documentation if the relationship is unclear.
Do not use for
Do not use this code for papilledema without documentation of decreased ocular pressure. Do not assign it for other optic disc swelling causes or for glaucoma-related pressure changes unless the provider makes this specific association.
Coding tip
Verify that both papilledema and decreased ocular pressure are documented together before coding H47.12.
