About 69645: Tympanoplasty with complete mastoidectomy
Reports tympanic membrane and middle-ear repair performed with complete mastoidectomy when the surgeon does not reconstruct the ossicular chain.
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.
