Nov. 07, 2019

The below announcement applies to providers submitting claims for the following Blue Cross and Blue Shield of Montana (BCBSMT) government programs members:

  • Blue Cross Medicare Advantage (PPO)SM

Reversals and corrections may occur when claim adjudication results have been modified from a previous claim report. The method for revision is to reverse the entire claim and resend with modified data. Provider level adjustments are reported in the Provider Level Balance (PLB) segment within the 835 ERA from BCBSMT.

As of Dec. 5, 2019, the following information will change in the 835 ERA PLB segment for the above-referenced members' claims:

  • Adjustment Reason Code (PLB03-1) – qualifier FB (Forward Balance) will be replaced with qualifier WO (Overpayment Recovery – negative amount).
  • Provider Adjustment Identifier (PLB03-2) – this field currently contains check number and will be replaced with patient control number and payer document control number (DCN) of the overpaid claim.
    • Example: PLB*15483NN082*20191231*WO:JONES001 181580099999*-1156
