Summary
BCBS Illinois clarifies billing requirements for behavioral health services, emphasizing that out-of-network providers must bill under their own NPI, trainees must have direct supervision, and a new HL modifier for trainee services will be implemented in the future. These rules also apply to physical health services.
Action Required
Immediately: Review all behavioral health billing to ensure out-of-network providers are billing under their own NPI, not the group practice NPI. Verify trainee services have proper supervision documentation. Do NOT use the HL modifier until BCBSIL provides notification. Review FAQ and reimbursement policy CPCP029 for compliance.
