What 66710 covers

An ophthalmologist directs laser energy through the outer wall of the eye to treat the ciliary body and reduce aqueous humor production. This procedure is used to lower intraocular pressure in glaucoma, particularly when pressure remains difficult to control despite other treatment. It is typically performed in an outpatient surgical setting, with the treated eye and transscleral approach documented in the operative report.

Report 66710 for transscleral cyclophotocoagulation; distinguish it from ciliary-body destruction using another technique. Document the indication, eye treated, method, and procedure performed. The code has a 90-day global period, including the day-before preoperative visit and 90 days of related postoperative care. For bilateral treatment with modifier 50, CMS pays 150%. When multiple procedures occur in the same session, the highest-valued procedure is paid in full and others at 50%. CMS does not pay an assistant at surgery; 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.
