Summary & Overview
CPT 69601: Revision Simple to Total Mastoidectomy
CPT code 69601 denotes a revision otologic surgery converting a prior simple mastoidectomy to a total mastoidectomy, often including removal of diseased mastoid mucosa or cholesteatoma. This procedure addresses persistent or recurrent middle ear infection, ongoing drainage, tympanic membrane perforation, and residual hearing loss when the initial mastoidectomy failed to achieve a dry, stable ear. Nationally, procedures like this carry clinical and payer significance because they represent more extensive surgical management for recurrent or complicated otitis media and cholesteatoma, with implications for utilization, facility resources, and postoperative care.
Key payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise clinical context for the procedure, typical sites of service (hospital OR or ambulatory surgical center), and how the code is used to describe revision mastoid surgery. The publication summarizes common modifiers and related administrative considerations, highlights billing and coding relationships, and provides benchmarks and policy context where available. Data not available in the input is noted as such. The goal is to give clinicians, billing staff, and policy stakeholders a clear, national-level overview of CPT code 69601 and its clinical role in treating recurrent otitis media and cholesteatoma.
Billing Code Overview
CPT code 69601 describes a surgical revision in which a previously performed simple mastoidectomy is converted to a total mastoidectomy. The procedure includes removal of diseased mastoid mucosa or cholesteatoma when present and is performed when the prior operation failed to produce a dry ear, resulting in recurrent otitis media with pus accumulation, tympanic membrane perforation, and recurrent or residual hearing loss. Acute or recurrent cholesteatoma may also be an indication.
-
Service type: Revision mastoidectomy (conversion from simple to total mastoidectomy); surgical otologic procedure
-
Typical site of service: Hospital operating room or ambulatory surgical center (OR/ASC)
Clinical & Coding Specifications
Clinical Context
A 45-year-old patient with a history of chronic otitis media previously underwent a simple mastoidectomy but continues to have a persistently wet ear, recurrent purulent drainage, tympanic membrane perforation, and progressive conductive hearing loss. Examination and CT temporal bone imaging demonstrate residual disease with persistent infected mastoid air cells and possible cholesteatoma. The otologic surgeon elects to revise the prior simple mastoidectomy and convert it to a total (radical) mastoidectomy, removing diseased mastoid mucosa and any residual cholesteatoma. The clinical workflow includes preoperative assessment (history, audiogram, CT temporal bones), informed consent with discussion of goals and risks, intraoperative conversion of the prior mastoid cavity to a total mastoidectomy with disease clearance, possible ossicular chain evaluation or reconstruction later depending on intraoperative findings, and postoperative care with antibiotic therapy, wound care, audiologic follow-up, and imaging as indicated. Typical perioperative documentation includes operative note describing conversion of the prior procedure, extent of disease removed, estimated blood loss, specimen handling, and postoperative plan for surveillance and hearing rehabilitation.
