Summary
Excellus BlueCross BlueShield has updated their policy defining medical necessity criteria for coverage determinations. This is an annual review with no changes to policy intent, but reinforces the six key criteria all services must meet for coverage and emphasizes that provider orders alone don't guarantee coverage.
Action Required
By October 16, 2025: Billing team should review current documentation practices to ensure all claims include comprehensive clinical information supporting medical necessity. Verify that all prior authorization requests include complete medical records, as requests without clinical notes, lab tests, or imaging studies will be automatically denied. Update provider education materials to emphasize that a prescription or order alone does not guarantee coverage.
