Summary
BCBS Mississippi updated their medical policy for Intensity-Modulated Radiotherapy (IMRT) for breast and lung cancer, establishing specific criteria for when IMRT is considered medically necessary versus investigational. The policy defines strict dosimetry and clinical requirements that must be met for coverage approval.
Action Required
Immediately: Billing team must review all pending and future IMRT claims for breast and lung cancer to ensure they meet the specific medical necessity criteria outlined in policy A.8.01.46. Providers must document that alternative radiotherapy cannot avoid cardiac exposure for left-sided breast cancer, demonstrate hot spots >10% dose variation for large breast cases, and show V20 reduction of at least 10% for lung cancer cases. Claims not meeting these criteria will be considered investigational and denied.
