Missing NM103 - subscriber last name






Kareo Validation Error

This rejection indicates that the patient’s insurance policy is through another individual but a valid last name has not been populated for the insured.

Claims billed without the insured first and last name will reject at the clearinghouse; therefore Kareo has held the claim until the error has been corrected. You must correct the error and resubmit the claims in order for them to be delivered to the payer.

Note: Since claims rejected within Kareo are not forwarded to the clearinghouse you will be unable to generate timely filing for that submission until validation errors have been corrected and the claim resubmitted.



Follow the instructions below enter the address for the Insured:

  1. Click Encounters > Track Claim Status.
  2. Look for and double-click on the encounter that needs correcting.
  3. Double-click on the case.
  4. Double-click on the insurance policy that the needs to be corrected.
  5. Navigate to the “Insured” section and click on Full Name.
  6. Enter the insured last name in the corresponding field.
  7. Click Save all the way out.           

Then, rebill and resubmit all affected claims.
