Corneal disorder due to contact lens, unspecified eye

This code signifies an unspecified corneal abnormality or disease that is directly attributed to contact lens wear. It indicates a general corneal issue, such as inflammation, erosion, or other damage, where the specific nature of the disorder is not documented. The condition affects an unspecified eye.

Use this code when documentation clearly links a corneal disorder to contact lens use, but the specific type of corneal disorder (e.g., ulcer, edema, neovascularization) is not specified. This is appropriate for initial encounters or when the ophthalmologist or optometrist has not yet determined the precise diagnosis. Documentation should explicitly state "corneal disorder due to contact lens" without further detail.

• Do not use this code if a more specific corneal disorder due to contact lens is documented (e.g., corneal ulcer, edema).
• Ensure the documentation explicitly states the causality between contact lens wear and the corneal disorder.
• If the affected eye is specified (right or left), use the appropriate laterality code (H18.821 or H18.822).
