Cornea replaced by transplant

This diagnosis code indicates that a patient has undergone a corneal transplant, meaning their natural cornea has been surgically replaced with donor corneal tissue. This procedure is typically performed to restore vision in individuals with corneal diseases or injuries that have caused significant vision impairment.

Use this code for patients who have a history of receiving a corneal graft. It is appropriate for follow-up visits related to the transplanted cornea, such as monitoring for rejection, managing post-operative complications, or assessing long-term graft function.

• This code specifies the presence of a corneal transplant, not the reason for the transplant or any complications.
• Always code the underlying reason for the original transplant (e.g., corneal dystrophy, keratoconus) as an additional diagnosis, if known and relevant to the encounter.
• Do not use this code for the procedure itself; surgical codes (e.g., CPT codes) are used for the performance of the transplant.
