Summary
Blue Cross Blue Shield of Montana issued reminders for behavioral health billing requiring providers to use their own NPIs (no pass-through billing), maintain direct supervision of trainees 100% of the time, and follow proper claims submission procedures. A new modifier (HL) will be required for trainee services at a future date.
Action Required
Immediately: Ensure all behavioral health providers bill under their own NPI only - no pass-through billing allowed. Verify all trainee services have 100% direct supervision with supervising provider in immediate vicinity. Prepare for future implementation of HL modifier for trainee services (do not use until BCBSMT notification). Review Medical Record Documentation Guidelines CPCP029 in Availity Essentials.
