About 65850: Ab externo trabeculotomy for glaucoma
Reports glaucoma surgery that opens the trabecular drainage pathway through an external approach to improve aqueous outflow from the eye.
An ophthalmologist performs an ab externo trabeculotomy by approaching the drainage angle from outside the eye and opening the trabecular meshwork to improve aqueous humor outflow. The procedure is used for glaucoma, including congenital or developmental glaucoma, and is performed in a surgical setting. It differs from an internal angle incision because the surgeon reaches the trabecular meshwork through an external approach.
Report 65850 when the operative documentation supports this external approach and the trabecular incision. Record the treated eye and any other procedures performed during the session. Medicare assigns a 90-day global period, including the day-before preoperative visit and 90 days of related postoperative care. For multiple procedures in one session, the highest-valued procedure is paid in full and other procedures are paid at 50%. Bilateral reporting with modifier 50 is paid at 150%. Assistant-at-surgery payment is restricted; co-surgeon payment requires supporting documentation, and team surgery is not permitted.
