What 69645 covers
An otolaryngologist uses this code for tympanoplasty combined with complete mastoidectomy, including associated work in the ear canal or middle ear. A typical clinical setting is surgery for chronic middle-ear disease or cholesteatoma involving the mastoid. The distinguishing feature is the extent of mastoid removal; ossicular chain reconstruction is not part of this service.
Choose the code from the operative report, which should support complete mastoidectomy and describe the tympanoplasty and middle-ear work performed. The 90-day global period includes the day-before preoperative visit and 90 days of related postoperative care. For bilateral surgery reported with modifier 50, CMS pays at 150%. When multiple procedures are performed in one session, the highest-valued procedure is paid in full and the others at 50%. CMS does not pay an assistant at surgery for this code; co-surgeons and team surgery are not permitted.
