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

What 69511 covers

An otolaryngologist performs a radical mastoidectomy in the operating room to remove extensive disease involving the mastoid and middle ear and create an open surgical cavity. It is used for advanced chronic ear disease, including cholesteatoma, when the operative work is more extensive than a simple, complete, or modified radical mastoidectomy. Code 69511 distinguishes this operation from radical mastoidectomy performed with tympanoplasty.

Choose the code from the operative report’s documented extent and whether tympanoplasty was performed; the diagnosis alone does not establish the surgical level. Medicare assigns a 90-day global period, including the day-before preoperative visit and related postoperative care during that period. When multiple procedures are performed in the same session, the highest-valued procedure is paid in full and others at 50%. For bilateral surgery reported with modifier 50, payment is at 150%. Assistant-at-surgery payment requires documentation of medical necessity; co-surgeons and team surgery are not permitted.
