Ophthalmology surgery
About 66180: Aqueous shunt with graft
Reports glaucoma drainage-device placement to an extraocular reservoir with a graft covering the tube, typically for glaucoma requiring surgical pressure control.
An ophthalmologist places a drainage tube into the eye and connects it to a reservoir positioned outside the eye to divert aqueous fluid and lower intraocular pressure. A graft covers the exposed tube. This operation is generally selected for glaucoma that needs a drainage implant, including cases in which other pressure-lowering treatment has not provided adequate control. It is commonly performed in a hospital outpatient department or ambulatory surgery center.
Report this code when the procedure includes both the aqueous shunt to an extraocular reservoir and the graft. The operative report should support the glaucoma indication, shunt placement, and graft use; a shunt placement without a graft is distinguished by 66179. Medicare assigns a 90-day global period, including the day-before preoperative visit and 90 days of related postoperative care. For bilateral surgery, modifier 50 is paid at 150%. When multiple procedures occur in one session, the highest-valued procedure is paid in full and other procedures are reduced to 50%. An assistant at surgery may be paid; co-surgeons and team surgery are not permitted.
