What 66720 covers

An ophthalmologist uses a cryoprobe applied externally over the ciliary body to freeze targeted tissue and reduce aqueous humor production. This cyclocryotherapy procedure is used most often for glaucoma that remains difficult to control, including situations in which conventional pressure-lowering treatment has not achieved adequate control. It is generally performed as an eye surgery in an operating room or ambulatory surgery setting.

Choose this code for the cryotherapy technique, not for ciliary body treatment performed with diathermy or laser. The operative report should identify the treated eye, the ciliary body cryotherapy performed, and the clinical indication. CMS assigns a 90-day global period, including the day-before preoperative visit and 90 days of related postoperative care. When multiple procedures are performed in the same session, the highest-valued procedure is paid in full and other procedures are subject to the standard 50% reduction. For bilateral treatment reported with modifier 50, CMS pays 150%. 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.

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.
