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.
