Supplier Proof of Delivery Documentation Requirements

4.7.3.1 – Supplier Proof of Delivery Documentation Requirements (Rev. 11797; Issued: 01-19-23; Effective: 02-21-23; Implementation: 02-21-23) This section applies to UPICs. This section is applicable to DME MACs, RACs, SMRC, and CERT MR contractors, as noted in Ch. 5, Section 5.8. Suppliers are required to maintain proof of delivery documentation in their files. Proof of delivery documentation must be maintained in the supplier’s files for seven years (starting from the date of service). Section 1833(e) grants Medicare contractors the authority to request any information necessary to determine the amounts due. This includes proof of delivery in order to verify that the beneficiary received the DMEPOS item and thus to determine the amounts due to the provider. Proof of delivery is also one of the supplier standards as noted in 42 CFR § 424.57(c)(12). If the UPIC has reason to be concerned that Medicare was billed for an item that was not received (such as a complaint from a beneficiary about non-receipt), the UPIC shall request proof of delivery from the supplier. Proof of delivery documentation must be made available, within the prescribed timeframes, to the UPIC upon request. For any items that do not have proof of delivery from the supplier, such claimed items shall be denied by the UPIC and overpayments recovered. Suppliers that consistently do not provide documentation to support that their items were delivered may be referred to the OIG or NPE for investigation and/or imposition of sanctions.
