Payment models refer to the various methods used to compensate service providers or businesses for their products and services. Common types include fee-for-service, where providers are paid for each service rendered, and capitation, where a fixed amount is paid per patient regardless of the number of services provided. These models can influence the quality and efficiency of care delivered. Another important payment model is value-based care, which focuses on patient outcomes rather than the volume of services. In this model, providers are rewarded for improving patient health and reducing costs, encouraging a more holistic approach to healthcare delivery.
