How to Avoid Proof of Delivery (POD) Comprehensive Error Rate Testing (CERT) Errors for Method Two

Noridian has received notification of errors from CERT for POD Method Two.

CERT has identified the main cause of these errors is due to:

  • Invoice from supplier missing quantity of items delivered
  • Invoice from supplier missing tracking number from shipping company
  • Tracking document from shipping company missing evidence of delivery
  • Invoice from supplier missing beneficiary address
  • Tracking document from shipping company missing delivery address.

To be compliant with Standard Documentation Requirements for All Claims Submitted to DME MACs:

Documentation for Method Two delivery would include at a minimum:

  • Beneficiary’s name
  • Delivery address
  • Delivery service’s package identification number, supplier invoice number, or alternative method that links the supplier’s delivery documents with the delivery service’s records
  • A description of the item(s) being delivered. The description can be either a narrative description (e.g., lightweight wheelchair base), a HCPCS code, the long description of a HCPCS code, or a brand name/model number
  • Quantity delivered
  • Date delivered
  • Evidence of delivery

This documentation must be available upon request. If documentation is requested and does not substantiate that the item(s) delivered are the same item(s) submitted for Medicare reimbursement and that the item(s) are intended for, and received by, a specific Medicare beneficiary, claim(s) will be denied.
