Folds and rupture in Bowman's membrane, bilateral

This code describes a condition affecting both eyes where Bowman's membrane, a critical layer of the cornea, exhibits folds and/or ruptures. This can lead to corneal opacities, vision impairment, and may be associated with various corneal dystrophies or trauma.

Use this code when documentation explicitly states the presence of folds and/or ruptures in Bowman's membrane affecting both eyes. This is commonly seen in conditions like Reis-Bücklers corneal dystrophy or following significant corneal edema. The physician's notes should clearly specify the bilateral involvement.

• Ensure documentation specifies bilateral involvement; otherwise, use the appropriate unilateral code.
• Distinguish from other corneal dystrophies affecting different layers of the cornea.
• Code any underlying cause or associated corneal dystrophy as an additional diagnosis, if applicable.
