Hello, what documentation would be necessary to have in a patient file, if you ship the equipment/supply to their home through a delivery provider? For example, for a DME Supply item patient needs a refill of the equipment/supply item, and would like to be drop shipped to their home directly. Is it a tracking number from the delivery provider sufficient? Would a Delivery ticket with the supply items signed electronic, by the patient be sufficient to be compliant to bill insurance? Would tracking number from the delivery provider have to be on the signed Delivery Ticket? Any information or suggestions will be greatly appreciated. Thank you!
