Write Off:

This is an amount that the provider has to remove from his books. There are two types of write off: One is contractual write off and the other one is adjustments. Contractual write off are those wherein the excess of billed amount over the carrier’s allowed amount is written off. The fee schedules of each carrier will be loaded in the billing system. When you are posting the EOBs these fee schedules in the system also called system allowed amount would pop up. The difference between the billed amount and the system allowed amount will be the write off, if the EOB allowed amount is less than the system allowed amount. Otherwise the difference between the billed amount and the EOB allowed amount would be the write off.

De antemano mil gracias
