1. Specific dollar amount to be collected when services are received. For example, the patient might pay out of pocket $10 for each prescription received and the plan would pay the remaining cost of the drug. This cost-sharing arrangement is sometimes referred to as coinsurance and deductible, cooperative payment, and cost sharing. However, coinsurance has a slightly different meaning under some programs (see coinsurance). 2. Under the Medicare program, it is considered fraud to routinely waiver copayments and deductibles, regardless of need. 3. In the Medicaid program, a dollar amount that an individual must pay at each office visit for receiving medical and child care services. Different copayment amounts may be set for each patient type and certain medical procedures. Child care copayments are based on gross annual income, number in the home, and number needing child care. Note: If a health plan integrates the copayment into the membership fee, then do not collect copays from the patients (members) of the plan.
