Summary
BCBS Mississippi has established a new medical policy for radioactive seed localization of nonpalpable breast lesions. The procedure is considered medically necessary for guiding excisional biopsy or breast-conserving surgery, but may be denied if it costs more than wire localization alternatives due to 'least costly alternative' provisions.
Action Required
Immediately: Billing team must verify cost comparison between radioactive seed localization and wire localization before submitting claims to BCBS Mississippi. Document medical necessity and ensure procedure is not being used solely for provider or patient convenience. Review any existing claims for this procedure to ensure compliance with new coverage guidelines.
