Global capitation (Wikipedia, the free encyclopedia)
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. Rates are also affected by age, race, sex, type of employment, and geographical location, as these factors typically influence the cost of providing care.
