About 66740: Ciliary body destruction by other method
Ophthalmologists report this procedure when an uncommon method is used to ablate ciliary tissue to reduce aqueous production in difficult-to-control glaucoma.
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.
