What is Capitation?

Legal Definition
Capitation is a payment arrangement for health care service providers such as physicians or nurse practitioners. It pays a physician or group of physicians a set amount for each enrolled person assigned to them, per period of time, whether or not that person seeks care. These providers generally are contracted with a type of health maintenance organization (HMO) known as an independent practice association (IPA), which enlists the providers to care for HMO-enrolled patients. The amount of remuneration is based on the average expected health care utilization of that patient, with greater payment for patients with significant medical history.
