CPT code 69633: Tympanoplasty2026 Medicare rate & RVUs

Medicare pays $943.24 for 69633 nationally in a facility.

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

What 69633 covers

An otolaryngologist performs this operation to repair the tympanic membrane and reconstruct the middle-ear sound-conducting bones while also removing diseased mastoid air cells. It is commonly used for chronic middle-ear disease, including cases with ossicular damage and mastoid involvement. The surgery takes place in an operating room and may include canalplasty or other middle-ear work integral to the repair.

Select this code when the operative report supports both mastoidectomy and ossicular chain reconstruction as part of the tympanoplasty. Documentation should identify the mastoid work, eardrum repair, and reconstruction performed. Medicare assigns a 90-day global period, including the day-before preoperative visit and related postoperative care for 90 days. 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 surgery, modifier 50 is paid at 150%. Medicare does not pay an assistant at surgery for this service; co-surgeons and team surgery are not permitted.
