Summary & Overview
CPT 69511: Radical Mastoidectomy, Surgical Otologic Procedure
CPT code 69511 designates a radical mastoidectomy, an extensive otologic surgical procedure used to remove mastoid air cells and diseased temporal bone tissue. Nationally, this code is relevant for hospital-based and ambulatory surgical care involving chronic ear disease management, with implications for operative coding, facility billing, and clinical documentation. Key payers in typical analyses include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of the clinical intent behind the code, typical sites of service, and common billing considerations used by payers. The publication outlines benchmark metrics and policy context relevant to approval, coverage variation, and facility reimbursement frameworks. Clinical context covers indications such as chronic mastoiditis and cholesteatoma, while operational content addresses coding accuracy, documentation elements that support medical necessity, and common modifiers used in operative billing. Data not provided in the input are noted where applicable. This material is written for clinicians, coding professionals, and payers seeking a national perspective on the use and administrative handling of CPT code 69511.
Billing Code Overview
CPT code 69511 represents a radical mastoidectomy, a surgical procedure involving extensive removal of mastoid air cells and associated diseased tissue of the temporal bone. This procedure is typically performed to eradicate chronic infection, cholesteatoma, or other destructive processes that involve the mastoid and middle ear structures.

Service Type: Surgical otologic procedure
-
Typical Site of Service: Hospital operating room or ambulatory surgical center where otologic surgeries are performed
Clinical & Coding Specifications
Clinical Context
A 52-year-old patient presents with chronic, refractory mastoid and middle ear disease characterized by persistent otorrhea, extensive cholesteatoma, and progressive hearing loss despite prior tympanostomy and medical therapy. Preoperative evaluation includes otoscopic exam, high-resolution CT temporal bones demonstrating coalescent mastoiditis with destruction of mastoid air cell septations and extension toward the petrous apex, audiometry showing conductive hearing loss, and discussion with otolaryngology regarding surgical options. The surgical team elects to perform a radical mastoidectomy (69511) to eradicate disease by removing mastoid air cells, exteriorizing the mastoid and middle ear into a single cavity, and creating a postauricular approach for disease clearance.
Perioperative workflow: preoperative consent and anesthesia evaluation (general anesthesia), intraoperative facial nerve monitoring as indicated, postauricular incision, cortical bone removal, canal wall sacrifice as required to exteriorize the disease, ossicular assessment and possible staged ossiculoplasty, packing and dressing of the mastoid cavity, and postoperative inpatient or outpatient recovery with scheduled follow-up for cavity care and possible hearing rehabilitation. Documentation should include operative indications, extent of mastoidectomy, ossicular status, any adjuvant procedures, estimated blood loss, and any complications encountered.
