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

What 66160 covers

In iridencleisis, the ophthalmic surgeon creates a fistula through the sclera and secures a portion of the iris in the opening to maintain aqueous outflow and reduce intraocular pressure. It is a filtration operation for glaucoma, rather than laser treatment or placement of an aqueous shunt. The procedure is generally performed in an operating room, commonly in a facility setting, by an ophthalmologist experienced in glaucoma surgery.

Report 66160 when the operative technique is iridencleisis; select a different glaucoma procedure code when the surgeon performs another filtration method, such as trabeculectomy or shunt implantation. The operative report should establish the glaucoma indication and describe the fistula and iris manipulation. Medicare assigns a 90-day global period, including the day-before preoperative visit and 90 days of related postoperative care. For bilateral surgery reported with modifier 50, payment is 150%. When multiple procedures occur in one session, the highest-valued procedure is paid in full and others at 50%. Assistant-at-surgery payment is restricted; co-surgeon payment requires supporting documentation, and team surgery is not permitted.
