CPT code 69222 covers debridement of the mastoid cavity after mastoidectomy, a procedure used when the postoperative cavity requires operative cleaning under anesthesia or more extensive debridement than routine care. This code matters nationally because mastoid surgery and its sequelae are managed across inpatient and outpatient surgical settings, and repeated debridements can affect utilization, perioperative planning, and post-surgical resource use.

Key payers discussed include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. The publication provides clinical context for when 69222 is used, the typical sites of service, and common billing considerations. Readers will find benchmarks and comparisons of coverage practice among major payers, summaries of relevant policy elements that influence prior authorization and payment, and a concise clinical description of the procedure's role in postoperative mastoid care.

The content focuses on operational and policy-relevant information: definition and clinical scenario for use, payer coverage landscape, and what to expect in terms of service location and typical procedural setting. Data not available in the input is noted where relevant in the detailed sections.
