What 65820 covers

Goniotomy is an angle-based glaucoma operation: the surgeon views the drainage angle with a gonioscopic lens and makes an incision in the trabecular meshwork to improve aqueous outflow. It is classically used for congenital glaucoma when the angle can be visualized, and is performed by an ophthalmologist in an operating room. The procedure may also be performed with another eye operation when both services are indicated and documented.

Report the service for each treated eye and document the glaucoma indication, operative approach, and eye treated. CMS assigns a 90-day global period, including the day-before preoperative visit and 90 days of related postoperative care. For bilateral surgery, modifier 50 is paid at 150%. When multiple procedures occur in the same session, the highest-valued is paid in full and the others at 50%. Assistant-at-surgery payment requires documented medical necessity; co-surgeons and team surgery are not permitted.
