I'm new to DME coding and billing. I have a question regarding DME and the BlueCard program. If a patient who receives a DME supply outside of the DME company's state, do I bill our local BCBS even if we are not contracted, or do I bill the patient's home plan? I cannot find anything on the BCBS Associations website that specifies where to bill the claim. Also if I go onto a specific state BCBS website they tell me something different. Any help would be greatly appreciated.
