Effective June 1, 2020, Noridian began requiring suppliers to use the Noridian Medicare Portal (NMP) for all reopenings that are available through the Self-Service Reopening feature.

The Reopening process allows suppliers to correct clerical errors or omissions on denials received without having to request a formal appeal. Suppliers can initiate a request:

  • Self-Service reopening online via the Noridian Medicare Portal (NMP)
  • Telephone
  • Written
  • Spreadsheets/Special Projects
    • Call the Phone Reopenings to get the directions
      • If a spreadsheet is sent in without the correct information, it will be dismissed and a letter sent to the supplier

Minor clerical errors or omissions available for reopening include:

  • Diagnosis/procedure changes
  • Place of service changes - to POS 12 only
  • Date of service changes
    • The date of service cannot be changed to a date greater than the date that claim was originally received
    • Must be within the same calendar year except for Glucose and Nutrition
  • Modifier changes
  • Units of service changes
  • Billed Amount changes - Submitted amount and change amount must be < $10,000 (or must be sent to appeals)

Note: This is not an all-inclusive list.

Prior to Submitting Reopening Request

Before submitting a Reopening request, suppliers should research the claim denial reason to determine the proper way to resolve the denial and avoid it in the future. This can be accomplished through:

When the denial is identified, utilize the Denial Code Resolution Tool for guidance in resolving the denial. There are three options for resolving the denial. Correct the claim and rebill, reopening, and redetermination/appeal.

  • Rebill - Is the claim unprocessable which means the claim needs to be corrected and rebilled?
  • Reopening - Does the claim meet requirements for reopening?
    • Does not require documentation review
    • Not previously reopened or appealed
    • Not under review by Noridian or other review contractors
    • Not unprocessable indicated by denial code MA130
      • Resubmit/rebill these claims with corrections
    • HCPCS or denial reason not listed under too complex for reopening
    • Claim was not already paid
    • The remittance advice date must be within one year of the current date
    • The claim must be finalized
  • Redetermination/Appeal - Does the claim contain items too complex for a reopening and requires redetermination/appeal?

Suppliers must wait three business days following ERA or SPR receipt before submitting a request via the NMP or calling Telephone Reopenings. Do not resubmit a claim after submitting a Reopening request.

Unprocessable Claims - Correct and Rebill

Claims with remittance advice (RA) message MA130 cannot be reopened as they are unprocessable. "Your claim contains incomplete and/or invalid information, and no appeal or Reopening rights are afforded because the claim is unprocessable." Correct and submit a new claim with the complete/correct information.
