Every month Noridian receives thousands of claims sent in error. Many beneficiaries choose a Medicare replacement plan for their coverage, instead of Noridian Fee-For-Service Medicare. These claims should be sent to the appropriate Health Maintenance Organization (HMO), Medicare Advantage Plan or Preferred Provider Organization (PPO) for processing.

You will see a claim denial on your remittance advice with the codes CO-24, or a CO-109.

To avoid this error and shorten the amount of time it takes to get paid for claims, use the Noridian Medicare Portal (NMP) to identify Primary and Secondary payers before billing.

You can learn how to do this by reviewing our Tutorial on YouTube:
