A. Expected Fee Schedule

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

B. Payment Total

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