The Payment Mechanism determines reimbursement for services based on which of the following?

• A. It determines the reimbursement amount as a fixed fee
• B. It determines the calculation method only
• C. It determines reimbursement for services and how it is calculated based on factors such as a fee schedule or a percentage of billed amounts
• D. It determines whether a claim is eligible

Answer: (C)

The Payment Mechanism sets both how much will be paid for a service and how that amount is calculated. It defines the reimbursement amount and the method used to arrive at that amount, such as using a predetermined fee schedule or paying a percentage of the billed charges. For example, with a fee schedule, each service code has a fixed reimbursement amount, so billing $100 for that service would yield the schedule’s listed payment. With a percentage of billed charges, the payer pays a portion of what’s billed, like 70% of $100, which equals $70. Eligibility decisions happen separately in claims processing, so they don’t define the calculation method itself. This combination of determining the payment and the calculation approach is why this option best captures the concept.
