Commonly Used Terms for MSP:
The following commonly used terms and field explanations will serve as a guide for submitting proper electronic MSP claims.

Terms often seen on primary insurer Explanation of Benefits to indicate OTAF include but are not limited to: Contractual Adjustment, Network Discount, Provider Discount, Contract Write-off, Capitation Amount, PPO Discount, PPO Savings.
Contractual Obligation is the difference between billed amount and Obligation primary allowed amount that cannot be billed to the beneficiary.
Beneficiary responsibility is the amount that can be billed to the (PR) beneficiary, normally the difference between primary allowed amount and the primary paid amount. This amount can be equal to zero.
Approved Amount is the amount of money approved by the primary payer. The allowed equals the amount for the service line that was approved by the payer.
Line adjustments are required if the primary payer made line level adjustments that caused the amount paid to be different from the amount originally charged. Line adjustment information is reported in the CAS segment, including the claim adjustment group code, claim adjustment reason code and the monetary adjustment amounts.
