ICD-10 Code H15.81 – Equatorial Staphyloma (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H15.81 – Equatorial staphyloma
What it is
H15.81 identifies an equatorial staphyloma, a localized outward bulging of the eye wall near the equator of the globe. Use this code when documentation names this specific scleral or uveal outpouching.
Clinical signs
Clinical features vary; refer to documentation. Findings may include a visible or imaging-confirmed protrusion of the globe wall, sometimes with associated thinning or structural eye deformity.
When to use this code
Use H15.81 when the provider specifically documents equatorial staphyloma in the diagnosis, assessment, or problem list. It may also apply when ophthalmology records confirm the condition on exam or imaging. If the note only describes a nonspecific eye bulge, check documentation before coding.
Do not use for
Do not use this code for other staphylomas, general scleral thinning, or unspecified globe abnormalities. If the record does not clearly identify an equatorial staphyloma, use a more specific documented diagnosis or check documentation.
Coding tip
Code only when the provider names the condition; “eye protrusion” alone is not enough.
