Ring staphyloma, left eye

This code describes a ring-shaped ectasia or bulging of the sclera, typically occurring at the limbus, specifically affecting the left eye. This condition is a localized thinning and protrusion of the sclera, often associated with high myopia or inflammatory conditions.

Use this code when documentation clearly indicates a diagnosis of ring staphyloma in the left eye. This diagnosis is typically made through ophthalmic examination, including slit-lamp biomicroscopy and possibly imaging studies. The medical record should specify the affected eye.

• Ensure the documentation specifies "ring staphyloma" and not another type of staphyloma (e.g., equatorial, posterior).
• Verify the laterality; this code is specific to the left eye.
• Consider co-reporting with codes for underlying conditions such as high myopia (H44.2x) or inflammatory eye diseases if documented.
