ICD-10 Code H15.813 – Equatorial staphyloma, bilateral (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H15.813 – Equatorial staphyloma, bilateral
What it is
Equatorial staphyloma is an outpouching or thinning of the eye wall at the equator of the globe. “Bilateral” means it affects both eyes.
Clinical signs
Findings usually reflect localized scleral thinning or bulging on eye examination. Clinical features vary; refer to documentation.
When to use this code
Use H15.813 when the provider documents equatorial staphyloma in both eyes. Code it from ophthalmology notes, imaging reports, or operative documentation that clearly identifies the bilateral condition.
Do not infer laterality from a nonspecific staphyloma diagnosis. If the record does not state both eyes, check documentation before assigning this code.
Do not use for
Do not use this code for unilateral equatorial staphyloma or for other types of staphyloma unless the chart specifically says bilateral equatorial involvement. Check documentation.
Coding tip
Always confirm both the anatomic type and laterality in the provider note before selecting H15.813.
