Summary
BCBSWY clarified their diagnosis code policy: E&M services billed on the same date and claim as preventive medicine services will be denied if a Z code is the only diagnosis listed. The insurer also updated their Behavioral Health Guidelines with new documentation requirements.
Action Required
Immediately: Billing team must update claim submission procedures to ensure E&M services billed with preventive medicine on the same date include appropriate non-Z diagnosis codes. Review and implement updated Behavioral Health Guidelines for all behavioral health claims. Train staff on proper diagnosis code pairing to prevent E&M denials.
