What 66740 covers

An ophthalmologist uses this procedure to ablate ciliary body tissue by a method not represented by the separately identified diathermy, transscleral laser, endoscopic laser, or cryotherapy options. Reducing aqueous humor production can lower intraocular pressure in glaucoma that remains difficult to control despite other treatment. It is generally performed as an operative eye procedure in a facility; CMS utilization shows facility services rather than office services for 2024.

Report the code when the operative documentation identifies the ciliary-body destruction method and supports that it is not one of the specifically coded techniques. Record the treated eye, indication, and operative details; laterality supports bilateral reporting. This major surgery code carries a 90-day global period, including the day before surgery and 90 days of related postoperative care. For bilateral procedures, modifier 50 is paid at 150%. In same-session multiple procedures, the highest-valued procedure is paid in full and additional procedures at 50%. Medicare does not pay an assistant at surgery for this code; 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.

Where these rates come from

FeeBase calculates base physician payments from CMS work, practice-expense and malpractice RVUs, adjusted by each locality’s geographic indexes and the conversion factor. Services without a published rate are labeled, never given a made-up amount. Amounts are Medicare allowed amounts before claim adjustments: not a patient’s bill or a commercial rate.
