Summary & Overview
CPT 69637: Tympanic Membrane Repair with Ossicular Reconstruction and Mastoidectomy
CPT code 69637 represents a complex otologic operation that combines tympanic membrane repair (tympanoplasty), ossicular chain reconstruction with synthetic prostheses, and partial or complete mastoidectomy. This procedure addresses conductive hearing loss and chronic middle ear disease by restoring the integrity of the eardrum, rebuilding sound-conducting ossicles, and clearing diseased mastoid air cells. Nationally, the code is significant because it captures resource-intensive surgical care, multidisciplinary perioperative management, and implications for reimbursement and quality measurement in otology.
Key payers covered in the analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will learn the clinical context and typical care setting for CPT code 69637, how it is characterized for claims capture, and what to expect in terms of service complexity. The publication provides benchmarks and coding considerations relevant to hospitals and ambulatory surgical centers, summarizes typical sites of service and procedural components, and flags where input data are incomplete. Data not available in the input are explicitly noted so readers can identify gaps for operational or policy follow-up.
Billing Code Overview
CPT code 69637 describes a combined middle ear surgical procedure in which the provider reconstructs the tympanic membrane (eardrum) to repair a perforation and reconstructs the ossicular chain using synthetic prostheses to improve conductive hearing. The described procedure also includes removal of all or part of the mastoid (mastoidectomy) and may involve reconstruction of the ear canal, an incision into the tympanic attic, tympanic membrane repair, and additional middle ear surgeries as part of a single operative session.

Clinical & Coding Specifications
Clinical Context
A 52-year-old patient presents with chronic conductive hearing loss and persistent tympanic membrane perforation after recurrent otitis media. Examination and audiometry confirm a large central perforation of the tympanic membrane with ossicular chain discontinuity and mixed mastoid sclerosis on CT imaging. The otologic surgeon schedules a combined tympanoplasty with ossiculoplasty and mastoidectomy to reconstruct the tympanic membrane, replace disrupted ossicles with a synthetic prosthesis, and remove diseased mastoid air cells.
Preoperative workflow includes history and physical, audiogram, CT temporal bones, anesthesia evaluation, and informed consent addressing risks of hearing change, taste disturbance, dizziness, and need for staged procedures. Intraoperative steps typically include general anesthesia, postauricular incision or endaural approach, cortical mastoidectomy as indicated, tympanic attic inspection, ossicular reconstruction with partial or total ossicular replacement prosthesis, tympanic membrane repair (graft placement), and possible ear canal reconstruction. Postoperative workflow includes routine PACU recovery, short-term antibiotics and ear precautions, wound checks, audiometry at 6–12 weeks, and potential staged revision if graft or prosthesis fails to restore adequate conduction.
