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

What 69666 covers

An otologist or other otolaryngologist uses this code to repair a fistula at the oval window, the opening between the middle ear and inner ear. The procedure is generally performed in an operating room. A perilymph leak at this site may be associated with hearing symptoms or vertigo, including after trauma or prior ear surgery. The operative report should identify the oval window as the repair site and describe the fistula and its treatment.

Report the code for the oval-window repair itself, not for a leak at the round window or a procedure directed at stapes fixation. The service has a 90-day global period, which includes 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 the others at 50%. For bilateral repair, modifier 50 is paid at 150%. Assistant-at-surgery payment requires documentation of medical necessity; co-surgeons and team surgery are not permitted.
