What 66711 covers

An ophthalmologist uses an endoscope and laser probe inside the eye to view and treat the ciliary processes, reducing aqueous humor production and helping lower intraocular pressure. The procedure is used for glaucoma that remains difficult to control, including cases in which medication or prior treatment has not adequately controlled pressure. It is generally performed in an operating room or other surgical setting.

Select this code for the endoscopic approach, rather than a transscleral or other ciliary-body treatment. The operative report should support the endoscopic method, treated eye, and procedure performed. CMS assigns a 90-day global period, including the day-before preoperative visit and 90 days of related postoperative care. For bilateral treatment, modifier 50 is paid at 150%. When related endoscopies are performed together, endoscopy-family pricing applies. Assistant-at-surgery payment is restricted; 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.
