Large group practices may also establish management services organizations to sell management services to other physician groups.
Medicaid (Title XIX) — a federally aided, state-operated and -administered program that provides medical benefits for certain indigent and low-income persons in need of health and medical care. The program, authorized by Title XIX of the Social Security Act, is basically for low-income people.

Subject to broad federal guidelines, states determine the benefits covered, program eligibility, rates of payment for providers and methods of administering the program.

point of service — a health insurance benefits program in which subscribers can select among different delivery systems (e.g., health maintenance organizations, preferred provider organizations or fee-for-service arrangements) when in need of health care services, rather than making the selection among delivery systems at time of open enrollment at place of employment.
pre-existing condition — a medical condition developed prior to issuance of a health insurance policy.
preferred provider organization — formally organized medical entity, such as a hospital or physician, that provides health care services to purchasers, usually at discounted rates in return for expedited claims payment and a somewhat predictable market share. In this model, consumers have a choice of using providers in or out of the health insurance network; however, financial incentives are built in to benefit structures to encourage utilization of providers within the network.
prepayment — usually refers to any payment to a provider for anticipated services, such as an expectant mother paying in advance for maternity care. Sometimes prepayment is distinguished from insurance as referring to payment to organizations that, unlike insurance companies, take responsibility for arranging for, and providing, needed services as well as paying for them, such as health maintenance organizations, prepaid group practices and medical foundations.

prevalence — the number of cases of disease, infected persons or persons with some other attribute present at a particular time and in relation to the size of the population from which drawn. It can be a measurement of morbidity at a moment in time, e.g., the number of cases of hemophilia in the country as of the first of the year.
preventive medicine — care that has the aim of preventing disease or its consequences, including health care programs aimed at warding off illnesses (e.g., immunizations), detecting diseases (e.g., Pap smears) and inhibiting further deterioration of the body (e.g., exercise or prophylactic surgery). Preventive medicine developed following discovery of bacterial diseases and was concerned in its early history with specific medical control measures taken against the agents of infectious diseases. Preventive medicine is also concerned with general preventive measures aimed at improving the healthfulness of the environment. In particular, the promotion of health through altering behavior, especially using health education, is gaining prominence as a component of preventive care.
primary health care — basic or general health care focused on the point at which a patient ideally first seeks assistance from the medical care system. Primary care is considered comprehensive when the primary care provider takes responsibility for the overall coordination of the care of the patient's health problems, be they biological, behavioral or social.

Such care is generally provided by physicians but is increasingly provided by other personnel, such as nurse practitioners and physician assistants.
