Request a Reopening

Note: Unprocessable claims with Remittance Advice (RA) message MA130 cannot be reopened. ("Your claim contains incomplete and/or invalid information, and no appeal or Reopening rights are afforded because the claim is unprocessable. Submit a new claim with the complete/correct information.")

Before submitting a Reopening request, suppliers must research the claim denial reason (see Standard Paper Remittance (SPR) or Electronic Remittance Advice (ERA), call Interactive Voice Response (IVR), access NMP, or contact Supplier Contact Center) and determine the proper way to correct it.

Suppliers must wait three business days, following ERA or SPR receipt, before calling Telephone Reopenings or submitting a request via NMP.

Do not resubmit a claim after submitting a Reopening request.
