Unspecified corneal membrane change

This code signifies a non-specific alteration or abnormality of the corneal membrane, where the exact nature or cause of the change is not documented. It indicates a structural modification to the cornea that is not further characterized by the provider.

Use this code when documentation indicates a corneal membrane change but lacks specific details regarding its type (e.g., degeneration, dystrophy, scar, or other specific lesion). This code is appropriate when the physician notes a "corneal membrane change" without further elaboration.

• Avoid using this code if more specific documentation is available regarding the type of corneal membrane change. Query the provider for clarification if possible.
• This is a "catch-all" code; strive for greater specificity if the medical record permits.
• Consider sequencing this code after any underlying systemic conditions that may be contributing to the corneal change, if documented.
