ICD-10 Code H15.819 – Equatorial staphyloma, unspecified eye (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H15.819 – Equatorial staphyloma, unspecified eye
What it is
Equatorial staphyloma is an outward bulging of the eye wall at the equator of the globe. “Unspecified eye” means the record does not identify right or left eye.
Clinical signs
Clinical features vary; refer to documentation. Typical findings may include a localized scleral or uveal outpouching seen on eye examination or imaging, with associated structural eye deformity.
When to use this code
Use H15.819 when the provider documents equatorial staphyloma and does not specify which eye is affected. It is appropriate for confirmed diagnosis in ophthalmology notes, imaging reports, or problem lists. Check documentation if the record describes a different staphyloma type.
Do not use for
Do not use this code for staphyloma of a specified eye when laterality is documented. Also avoid it if the note describes another ocular bulging disorder or only a suspected finding.
Coding tip
Capture laterality whenever possible; if it is missing, code the unspecified-eye option only when documentation supports the diagnosis.
