Corneal surgery
About 65770: Artificial corneal prosthesis implantation
Reports surgical placement of an artificial corneal device, often for severe corneal disease when donor-tissue transplantation is unsuitable or has failed.
An ophthalmic surgeon places an artificial optical device in the cornea to restore a usable visual pathway when severe corneal damage prevents vision. This approach may be considered for patients with advanced corneal disease, including cases in which prior corneal grafts have failed or a conventional donor-tissue graft is not a suitable option. The procedure is generally performed in an operating room rather than an office setting.
Report the service when the operative record supports implantation of a keratoprosthesis, not a donor-cornea transplant or a procedure limited to the ocular surface. The code has a 90-day global period that includes the day-before preoperative visit and 90 days of related postoperative care. When multiple procedures are performed in the same session, the highest-valued procedure is paid in full and the others at 50%. For bilateral surgery, modifier 50 is paid at 150%. An assistant at surgery may be paid; co-surgeons and team surgery are not permitted.

65770 billing questions
How is this different from a corneal transplant code?
This code represents implantation of an artificial corneal device. Corneal transplant codes represent procedures using donor corneal tissue, with the applicable code selected according to the transplant technique and clinical details.
Are related postoperative visits separately reported?
The 90-day global period includes the day-before preoperative visit and 90 days of related postoperative care.
How is bilateral surgery reported?
Report modifier 50 for bilateral surgery. CMS pays the bilateral procedure at 150%.
Can an assistant surgeon be reported?
An assistant at surgery may be paid for this procedure. Co-surgeons and team surgery are not permitted.
What happens when another procedure is performed in the same session?
Under the standard multiple procedure reduction, the highest-valued procedure is paid in full and the other procedures are paid at 50%.
What documentation supports reporting this code?
The operative report should identify implantation of an artificial corneal device and document the procedure performed. A record describing only a donor-tissue graft or ocular-surface treatment does not establish this service.
Where these rates come from
FeeBase calculates base physician payments from CMS work, practice-expense, and malpractice RVUs, adjusted by each locality’s geographic indices and the applicable conversion factor. Unavailable or separately priced services are labeled rather than assigned a made-up amount.
