### A. Expected

The mandated reimbursement amount per California’s Official Medical Fee Schedule (OMFS). The Expected reimbursement amount is calculated using the fee schedules in effect for the entered Date of Service. The Expected reimbursement amount incorporates fee-affecting workers' comp billing ground rule calculations (eg., surgical cascading, MPPR, NCCI, MUE) and modifiers. The Expected reimbursement amount does not calculate contracted or network discounts.

### B. Payment Amount

The reimbursement amount paid by the claims administrator as reported on an Explanation of Review (EOR) and entered in the Payment Amount field on the previous screen. If not provided, this optional field defaults to $0. The Payment Amount is used to calculate the Expected %.

### C. Balance Due

The Balance Due amount represents the Expected reimbursement amount minus the Payment Amount.
