Corneal disorder due to contact lens, bilateral

This code signifies a corneal abnormality affecting both eyes, directly caused by contact lens wear. This can encompass various contact lens-induced issues such as corneal edema, infiltrates, or superficial punctate keratitis, impacting the integrity and function of the cornea.

Apply this code when documentation clearly links a bilateral corneal disorder to contact lens use. This includes conditions like contact lens-induced acute red eye (CLARE) or sterile infiltrates affecting both corneas. Supporting documentation should specify the bilateral involvement and the causative role of contact lenses.

• Ensure the documentation explicitly states "bilateral" involvement of the cornea.
• Distinguish from unilateral corneal disorders due to contact lenses (H18.821, H18.822).
• Code any underlying or associated infections (e.g., bacterial keratitis) separately, if documented.
