Determining Crossover Claims
When ERA files are imported, you can determine from the Complimentary Insurance Flag field if the claim has been handled as a crossover, even if the payer is not set up to be a crossover. A value of NM1*TT in this field indicates that the insurance that was billed, automatically forwarded the balance of the claim to the secondary insurance, regardless of the crossover flag in the application.
By using the Complimentary Insurance Flag, you can make sure that the Medicare payers that automatically forward remaining balances to a secondary insurance are correctly handled in the application. When transaction detail records are created from the ERA process for crossover claims, the Status is set to Forwarded to and the Charge Rebill Indicator is set to N, so the secondary payer is not flagged for billing.
