Reminder for Billing Attending Provider on UB-04 and 837I Claims, CR 110840

This is a reminder that the attending provider is required on all UB-04 and 837I claims. MaineCare denies UB-04 and 837I claims submitted without an enrolled attending provider.

The attending provider is the individual who has overall responsibility for the patient’s medical care and treatment reported in the claim/encounter. The attending provider requirement includes all claim submission methods (paper, HealthPAS Online Portal, or 837I).
