About 65450: Corneal lesion destruction treatment
An ophthalmologist destroys a focal corneal lesion with a selected treatment method rather than excising it or taking tissue for diagnosis.
This ophthalmic procedure treats a focal lesion on the cornea by destroying the target with a selected method, such as freezing, light-based coagulation, or heat cautery. It is generally performed by an ophthalmologist, often a cornea specialist, in an office procedure room or ambulatory surgical setting. It differs from cutting out corneal tissue, sampling it for diagnosis, or removing a broader area of surface epithelium.
Report the service for the treated eye and document the lesion’s location, the treatment method, and the work performed. Medicare assigns a 90-day global period, including the day-before preoperative visit and 90 days of related postoperative care. When multiple procedures are performed in one session, the highest-valued procedure is paid in full and the others at 50%. For bilateral treatment, modifier 50 is paid at 150%. Medicare does not pay an assistant at surgery; co-surgeons and team surgery are not permitted.
