Corneal transplant failure, bilateral

This code signifies the failure of a corneal transplant in both eyes. This means that the transplanted corneal tissue in both the right and left eyes has not successfully integrated or is no longer functioning as intended, leading to vision impairment or other complications.

This code is appropriate when a patient presents with complications or rejection of a previously performed corneal transplant affecting both eyes. It should be used when the physician explicitly documents bilateral corneal transplant failure, regardless of the underlying cause of the failure (e.g., rejection, infection, decompensation).

• Ensure documentation clearly specifies "bilateral" involvement of the corneal transplant failure.
• Do not use this code if only one eye is affected; specific codes exist for unilateral failure.
• Code any underlying cause of the transplant failure (e.g., graft rejection, infection) as an additional diagnosis.
