Which payment method involves an agreement between payer and provider on a reasonable amount for services rendered?

The most appropriate answer highlights the capitation payment method, which involves an agreement between payer and provider on a predetermined amount for a range of services. In a capitation model, healthcare providers are paid a fixed amount for each enrolled patient over a specified time period, regardless of the number of services provided. This system is designed to encourage efficient care and emphasize preventive services, as physicians benefit financially from keeping patients healthy and reducing unnecessary procedures.

The structure of capitation allows for straightforward budgeting and encourages healthcare providers to manage the costs of care effectively, creating a clear incentive for quality patient management while limiting excess spending on services that may not be necessary. This contrasts with other payment methods where reimbursement is based on individual services rendered or claims submitted, which may not facilitate the same level of agreement on a reasonable amount for services.
