How to Submit a Corrected Claim to Avoid Rejection


To prevent your corrected claim from getting rejected as a duplicate claim, ask your software vendor to do the following:

  • Populate the claim with the frequency type code of 7 (adjustment) in Loop 2300 (CLM5-3).
  • Populate the Original Reference Number (ICN/DCN in Loop 2300 with the UniCare claim number).

If you file your claims using free web-based transactions without a vendor, you should also follow the above steps when submitting corrected claims to avoid the claim getting rejected as a duplicate.

Trading partners can also purchase the full Technical Report Type 3 (TR3) guides from Washington Publishing Company.
