The AMO amount corresponds to the amount theoretically reimbursable by compulsory health insurance.

This is a theoretical amount because we have FSE before the control by the body of social security which issues a payment notice (or NOEMIE return) specifying the payment or rejection of the invoice.

Amount AMO = (Reimbursement basis * Rate applicable to the service) - Remainder payable [if applicable]
