About 66761: Laser peripheral iridotomy for angle closure
An ophthalmologist uses laser energy to create an opening in the peripheral iris, commonly to address narrow angles or angle-closure risk.
This procedure creates an opening through the peripheral iris with laser energy so aqueous fluid can pass between the posterior and anterior chambers. Ophthalmologists commonly perform it at a slit lamp in an office setting for eyes with narrow or occludable angles, including treatment or prevention of angle closure. The service is distinct from reshaping the iris with laser or removing iris tissue through an incision.
Report the service for the laser iridotomy session, not by laser pulse or opening. Documentation should identify the treated eye or eyes, the angle-closure indication, and the laser treatment performed. CMS assigns a 10-day global period, which includes related postoperative visits during that period. 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% reduction. For bilateral treatment, modifier 50 is paid at 150%. Assistant-at-surgery payment is restricted; co-surgeons and team surgery are not permitted.
