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

What 66989 covers

An ophthalmologist removes the cataract, places an intraocular lens during the same procedure, and inserts an aqueous drainage device internally into the trabecular meshwork to improve aqueous outflow. The cataract portion must be complex, involving a device or technique not generally used in routine surgery; examples include an iris expansion device, suture support for the lens implant, or primary posterior capsulorrhexis. These combined procedures are typically performed in an operating room at an ambulatory surgery center or hospital.

Report this code when both the complex cataract procedure and the specified trabecular drainage-device insertion are performed. The operative record should support the complex technique or device and document the lens implantation and drainage-device placement. CMS assigns a 90-day major-surgery global period, including the day-before preoperative visit and 90 days of related postoperative care. For multiple procedures in one session, the highest-valued procedure is paid in full and others at 50%; bilateral reporting with modifier 50 is paid at 150%. Assistant-at-surgery services are subject to statutory nonpayment; co-surgeons and team surgery are not permitted.
