CMS Pub. 100-08, ch. 4, § 4.7.3.1
Supplier Proof of Delivery Documentation Requirements
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.
