Deactivation, Suspension and Reactivation

Do Not Forward “DNF”

With implementation of the DNF initiative, contractors were required to use “return service requested” envelopes for hard copy RAs, hard-copy checks and returned EFT payments.

If you are a provider that receives hard copies of RAs or checks and the post office returns either document to us due to an incorrect address, we must follow the CMS guidelines for the DNF initiative. A hold will be placed on your enrollment. No further payments or RAs will be generated until you furnish a new address that is verified.

Under the DNF initiative, you as a provider are required to update all addresses and/or bank information before the Medicare contractor can remove the hold and this includes (if applicable):

  • Bank account information (CMS-588 EFT Agreement)
  • Payee address
  • Billing address
  • Corporate address
