What 66770 covers

CPT 66770 describes surgical removal of a lesion involving the ciliary body, the structure inside the eye that produces aqueous humor. An ophthalmologist typically performs the procedure in an operating room, using an approach suited to the lesion’s location and extent. It is distinct from procedures that destroy ciliary tissue to lower intraocular pressure; those treat glaucoma rather than excise a lesion.

Select the code when the operative record supports excision of a ciliary body lesion. Documentation should identify the lesion’s site and describe the excision performed and the treated eye. CMS assigns a 90-day global period, including the day-before preoperative visit and 90 days of related postoperative care. When multiple procedures occur in the same session, the highest-valued procedure is paid in full and other procedures are subject to the standard 50% reduction. Bilateral reporting with modifier 50 is paid at 150%. Assistant-at-surgery payment is restricted; co-surgeons and team surgery are not permitted.
