ICD-10 Code H15.85 – Ring staphyloma (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H15.85 – Ring staphyloma
What it is
Ring staphyloma is an abnormal, ring-shaped thinning and bulging of the eye wall, usually involving the sclera and adjacent ocular tissues. It is a structural eye condition, not a symptom by itself.
Clinical signs
Clinical features vary; refer to documentation. Typical charting may mention a visible circumferential scleral protrusion, localized thinning, or prior severe ocular disease affecting the globe.
When to use this code
Use H15.85 when the provider specifically documents ring staphyloma as the diagnosis. It may appear in ophthalmology notes, surgical records, or problem lists describing a chronic structural deformity of the eye. If the record only states scleral thinning or another staphyloma type, do not assume this code.
Do not use for
Do not use this code for generic eye pain, redness, or nonspecific scleral abnormalities without a documented ring staphyloma. Check documentation if the note describes another staphyloma location or a different ocular disorder.
Coding tip
Code only when the exact term “ring staphyloma” appears, or when the clinician clearly documents it as the confirmed diagnosis.
