Summary & Overview
CPT 69643: Tympanic Membrane Repair with Mastoidectomy
CPT code 69643 covers surgical reconstruction of the tympanic membrane with concurrent mastoidectomy and potential reconstruction of the posterior ear canal wall. The code is focused on middle ear and mastoid structural repair and explicitly excludes ossicular chain reconstruction. Nationally, the code matters for otologic surgeons, hospital surgical services, and payers managing coverage of ear surgery for chronic ear disease, traumatic perforations, or recurrent infections.
Key payers in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of the clinical intent and typical sites of service for 69643, plus coverage and billing considerations relevant to major national payers. The publication summarizes benchmarks and payer-specific policy themes, highlights documentation and surgical scope expectations tied to the code, and outlines the clinical context in which this procedure is commonly billed.
This resource is aimed at surgical practices, billing teams, and policy analysts seeking clear guidance on coding scope, payer coverage patterns, and the clinical procedures represented by CPT code 69643 on a national scale.
Billing Code Overview
CPT code 69643 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 procedure may include reconstruction of the posterior ear canal wall using cartilage, bone, or synthetic materials and can involve reconstruction of the ear canal and other middle ear surgeries. Reconstruction of the ossicular chain is not included in this procedure.
Service type: Middle ear and mastoid reconstructive surgery
Typical site of service: Hospital inpatient or outpatient surgical center; ambulatory otologic surgery setting
Clinical & Coding Specifications
Clinical Context
A 45-year-old patient presents with a chronic tympanic membrane perforation and recurrent otorrhea after prior middle ear infections. The otolaryngologist evaluates with otoscopic exam and audiometry, documents conductive hearing loss and a non-healing central perforation with possible chronic otomastoiditis. The clinical workflow includes preoperative assessment (history, physical, hearing test, anesthesia evaluation), informed consent for tympanoplasty with mastoidectomy, perioperative administration of antibiotics per facility protocol, operative reconstruction of the tympanic membrane (tympanoplasty) and cortical or combined mastoidectomy to remove diseased mastoid air cells, possible reconstruction of the posterior canal wall using cartilage or bone grafts, and placement of ear packing or graft support. The procedure excludes formal ossicular chain reconstruction. Postoperative workflow includes PACU recovery, short-term activity restrictions, otic antibiotic and analgesic prescriptions, follow-up otologic exams and audiometry at 4–12 weeks, and wound/graft checks. Typical site of service is an ambulatory surgery center or hospital operating room. Service type is an operative otologic surgical procedure (tympanoplasty with mastoidectomy). Typical patient scenario: adult with chronic perforation and mastoid disease undergoing tympanoplasty with mastoidectomy under general anesthesia, no ossicular reconstruction performed.
