Summary & Overview
CPT 69641: Tympanic Membrane Reconstruction with Mastoidectomy
CPT code 69641 represents tympanic membrane reconstruction (tympanoplasty) combined with partial or complete mastoidectomy to repair eardrum perforations and address disease of the middle ear. The procedure covers reconstruction of the ear canal and middle ear surgeries but explicitly excludes ossicular chain reconstruction. Nationally, this code is important because it captures a common set of otologic operations that can impact hospital surgical volumes, specialty billing patterns, and clinical resource use across outpatient surgery centers and inpatient settings.
Key payers discussed include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of clinical scope and typical sites of service, plus context for why the code matters for coverage, billing consistency, and utilization benchmarking. The publication highlights benchmarks for service mix and site-of-service distribution, recent policy considerations affecting surgical setting determinations, and clinical context relevant to coding choices for middle ear surgery.
This summary equips coding managers, surgical program directors, and payer policy analysts with a clear description of what CPT code 69641 denotes, where the service is commonly provided, and what to expect in terms of payer relevance and policy focus at a national level.
Billing Code Overview
CPT code 69641 describes a surgical procedure in which the provider reconstructs the tympanic membrane (eardrum) to repair a perforation and performs removal of all or part of the mastoid. The operation may include reconstruction of the ear canal, tympanic membrane repair, and other surgeries of the middle ear. Reconstruction of the ossicular chain is explicitly not included in this procedure description.
Service type: Middle ear surgical procedure with mastoidectomy and tympanoplasty
Typical site of service: Hospital outpatient surgery center or inpatient hospital operating room, depending on clinical complexity and patient needs.
Clinical & Coding Specifications
Clinical Context
A typical patient is a 45-year-old with chronic otorrhea, hearing loss, and a persistent tympanic membrane perforation from prior infection and cholesteatoma. After audiometry, CT temporal bone, and failed conservative management, the otologic surgeon schedules a combined mastoidectomy with tympanoplasty. In the preoperative workflow the surgeon documents persistent middle ear disease, reviews imaging showing mastoid air cell opacification and ossicular continuity without need for ossicular reconstruction, obtains informed consent specific to tympanic membrane reconstruction and mastoid removal, and coordinates anesthesia and perioperative antibiotics. Intraoperatively the provider performs cortical or canal wall up/down mastoidectomy as indicated, removes diseased mastoid air cells, reconstructs the tympanic membrane (myringoplasty or tympanoplasty) and, if needed, performs canal reconstruction or ossicular inspection without ossicular chain reconstruction. Postoperative care includes packing removal, wound checks, audiometry follow-up, and documentation of operative findings and any complications for accurate coding and billing.
