ICD-10 Code H15.851 – Ring staphyloma, right eye (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H15.851 – Ring staphyloma, right eye
What it is
H15.851 identifies a ring staphyloma affecting the right eye. It describes an abnormal outward bulging of the eye wall in a ring-shaped pattern, documented on the right side.
Clinical signs
Clinical features vary; refer to documentation. Findings may include visible scleral thinning or ectasia, altered globe contour, and associated visual disturbance if the lesion affects ocular structure.
When to use this code
Use this code when the provider documents ring staphyloma specifically in the right eye. It is appropriate when the diagnosis is confirmed clinically or by ophthalmic examination and laterality is clearly stated.
Choose this code for right-eye involvement only, even if the condition is longstanding or found during follow-up. Check documentation if the note uses a broader term without laterality.
Do not use for
Do not use this code for left-eye or bilateral ring staphyloma. Do not assign it when the record only mentions nonspecific staphyloma or another ocular deformity; check documentation.
Coding tip
Verify both the diagnosis and laterality in the ophthalmology note before coding H15.851.
