Medicare allowed amount for participating (non-QP) physicians, before deductible, coinsurance and claim adjustments. Not a patient’s bill or a hospital charge.

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.
