What 69644 covers

An otolaryngologist performs this operation to remove disease from the mastoid and middle ear, repair the eardrum, and reconstruct the ossicular chain while preserving or rebuilding the ear canal wall. It is commonly used for chronic middle-ear disease, including cholesteatoma, when surgery requires both mastoid work and restoration of the sound-conducting bones. The operation is generally performed in a surgical facility under anesthesia.

Select this code when the operative report supports mastoidectomy, tympanic membrane repair, ossicular chain reconstruction, and an intact or reconstructed canal wall. Documentation should describe the disease removed, the eardrum repair, the ossicular reconstruction, and the canal-wall approach. CMS assigns a 90-day 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 payment is restricted; co-surgeons and team surgery are not permitted.
