ICD-10 Code H15.821 – Localized anterior staphyloma, right eye (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H15.821 – Localized anterior staphyloma, right eye
What it is
Localized anterior staphyloma of the right eye is an outward bulging of a weakened area of the front part of the eye wall. The code specifies that the finding is limited and affects the right eye.
Clinical signs
Clinical features vary; refer to documentation. Typical findings may include a visible anterior bulge, thinning of the cornea or sclera, and associated distortion of the eye surface.
When to use this code
Use this code when the provider documents a localized anterior staphyloma in the right eye. It is appropriate when the condition is confirmed on exam or imaging and laterality is clearly stated. Check documentation if the note only describes a general staphyloma without eye laterality.
Do not use for
Do not use this code for staphyloma of the left eye, unspecified eye, or posterior staphyloma. If the record only mentions corneal scarring, ectasia, or thinning without staphyloma, code the documented condition instead.
Coding tip
Verify laterality and whether the staphyloma is anterior and localized before assigning H15.821.
