Corneal transplant failure, left eye

This code signifies the unsuccessful outcome of a corneal transplant procedure performed on the patient's left eye. It indicates that the transplanted corneal tissue has failed to function adequately, leading to a decline in vision or other complications requiring further intervention.

Apply this code when documentation clearly states that a previously performed corneal transplant in the left eye has failed. This includes scenarios where the graft has become opaque, rejected, or developed other irreversible complications. It should be used for subsequent encounters related to the management of this failed transplant.

• Ensure laterality is precisely documented as "left eye" to support this specific code.
• Distinguish between initial transplant complications (e.g., infection, edema) and definitive transplant failure.
• Code any underlying cause of the failure (e.g., graft rejection, infection) as an additional diagnosis.
