Cryoablation (CPB 0100, reviewed 2026-08-04)

Aetna has issued a comprehensive clinical policy bulletin (CPB 0100) establishing medical necessity criteria for cryoablation procedures across multiple anatomical sites and conditions. The policy clearly distinguishes between covered indications (e.g., renal masses up to 4cm, prostate cancer, atrial fibrillation, cervical dysplasia) and experimental/non-covered applications (e.g., breast carcinoma, benign prostatic hypertrophy, osteoarthritis). Billing teams must immediately implement these criteria as authorization rules to ensure claims are processed only when medical necessity requirements are met.
