Summary
BCBS Rhode Island now requires anatomical modifiers (like -RT, -LT, -50) on all surgical procedure codes 10000-69999 that have Medicare bilateral indicator '1'. Claims without proper anatomical modifiers risk duplicate payments, incorrect bundling, and claim delays.
Action Required
Immediately: Billing team must update system edits to require anatomical modifiers (-RT, -LT, -50) on all surgical codes 10000-69999 with Medicare bilateral indicator '1'. Update encounter forms and EMR templates to prompt providers for laterality documentation. Train staff on proper modifier usage to prevent claim denials and bundling errors.
