Ring staphyloma, unspecified eye

This code describes a localized thinning and bulging of the sclera, typically near the limbus, that is circular or ring-shaped. This condition is a degenerative change in the eye's outer fibrous layer, often associated with high myopia or inflammatory conditions. It represents an unspecified laterality, meaning it does not specify if it affects the right or left eye.

Utilize this code when documentation confirms a diagnosis of ring staphyloma without specifying the affected eye. This is appropriate when the physician's notes indicate the presence of the condition but do not provide laterality (e.g., "patient presents with ring staphyloma"). Avoid using this code if the medical record clearly indicates the specific eye involved.

• Always seek clarification from the provider if laterality is not documented, as more specific codes exist for right (H15.851) and left (H15.852) eyes.
• Do not confuse staphyloma with other scleral disorders like scleral ectasia or scleritis; ensure the documentation explicitly states "ring staphyloma."
• Code any underlying conditions contributing to the staphyloma, such as high myopia (H44.2x) or inflammatory eye diseases, as additional diagnoses.
