Summary
Humana Medicare Advantage has established new coverage criteria for microwave thermotherapy (microwave ablation). The policy covers specific hepatic and renal tumor treatments with detailed medical necessity requirements, but excludes breast, pancreatic, prostate, and bone cancer treatments.
Action Required
Before May 1, 2026: Billing team must update prior authorization requirements for microwave thermotherapy procedures. Verify all hepatic tumor treatments (CPT 47382, 47399) meet specific criteria including tumor size limits and surgical candidacy requirements. Confirm renal tumor treatments (CPT 50592) comply with staging and size restrictions. Stop billing CPT 19499, 48999, 53850, and 20982 for microwave ablation as these are not covered. Update billing system to flag contraindications and medical necessity documentation requirements.
