What 66625 covers

An ophthalmologist performs this surgical peripheral iridectomy to remove a portion of iris and create an alternate pathway for aqueous flow, commonly in treating angle-closure glaucoma. The procedure is performed in an operating room through a corneoscleral incision; it is distinct from creating an opening with a laser. The operative report should establish the glaucoma indication and document the iris tissue removed and surgical approach.

Report the code for the documented surgical iridectomy rather than a laser procedure or an iris excision that includes removal of a lesion. 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 the same session, the highest-valued procedure is paid in full and other procedures are subject to the standard 50% multiple-procedure reduction. For bilateral reporting with modifier 50, CMS pays 150%. Medicare does not pay an assistant at surgery; co-surgeons and team surgery are not permitted.

This summary was written with AI assistance from CMS physician fee schedule data and checked against the CMS billing rules shown here. Rates on this page come directly from CMS files.
