Summary & Overview
CPT 69642: Tympanic Membrane Repair with Mastoidectomy and Ossicular Reconstruction
CPT code 69642 represents a complex otologic surgical procedure combining tympanic membrane reconstruction (tympanoplasty), mastoidectomy, and ossicular chain reconstruction to address chronic ear disease and conductive hearing loss. This code is clinically significant nationwide because it describes multi-component ear surgery often performed for chronic otitis media with mastoid involvement or traumatic perforations and can affect surgical resource utilization, site-of-service decisions, and payment policy for otolaryngology practices and hospitals.
Key payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of clinical context, typical settings of care, and payer coverage considerations. The publication provides benchmarks for utilization and reimbursement patterns, summarizes recent policy updates relevant to otologic surgery coding and payment, and explains common clinical scenarios where 69642 is billed.
The content is intended for health system administrators, coding and billing staff, and clinical leaders seeking a clear, national-level summary of the procedure, its implications for site-of-service planning, and the main areas where payer policy affects billing and authorization practices. Data not available in the input will be noted where applicable.
Billing Code Overview
CPT code 69642 describes a combined surgical procedure in which the provider reconstructs the tympanic membrane (eardrum) to repair a perforation and performs partial or complete mastoidectomy, which may include reconstruction of the ear canal, tympanic membrane repair, additional middle ear surgeries, and reconstruction of the ossicular chain to improve conductive hearing.

Clinical & Coding Specifications
Clinical Context
A 45-year-old male presents with chronic right-sided otorrhea, conductive hearing loss, and an immobile tympanic membrane after prior failed tympanoplasty. Otoscopic exam and CT mastoid confirm a tympanic membrane perforation with cholesteatoma and mastoid air cell disease, with ossicular erosion causing conductive hearing loss. The patient is scheduled for mastoidectomy with tympanoplasty and ossicular chain reconstruction (reconstruction of the tympanic membrane, cortical mastoidectomy with removal of disease, possible canalplasty, and ossiculoplasty) under general anesthesia. Preoperative workup includes audiometry, CT temporal bone, medical clearance, and informed consent. Intraoperative workflow includes microscope-guided mastoid removal, careful disease eradication, reconstruction of the tympanic membrane (graft placement), ossicular chain reconstruction using prosthesis or autograft, hemostasis, and placement of packing or dressings. Postoperative care includes monitoring in PACU, pain control, antibiotic prophylaxis as indicated, wound and ear packing management, audiology follow-up, and documentation of findings, procedures, and any intraoperative complications.
