Health Insurance

Useful Definitions

Health Maintenance Organization (HMO):
A Health Maintenance Organization is a health care plan that provides benefits to any person or group of persons on a prepaid basis. Comprehensive health coverage is provided for enrollees through hospital services and physician services.
Indemnity Plan:
An Indemnity Plan is a health care plan that reimburses physicians for services performed or beneficiaries for medical expenses incurred. The plans are different from group health plans (HMOs, PPOs, etc.) that provide services through group medical practice.
Point-of-Service Plan (POS):
A Point-of-Service Plan is a health care plan that allows the patient to choose between an indemnity plan, a PPO, or an HMO each time he/she needs health care services. POSs are also known as open ended HMOs. Although the member is encouraged to choose a primary care physician, it is not required. Higher rates are assessed for individuals opting to use non-network physicians.
Preferred Provider Organization (PPO):
A Preferred Provider Organization is a group of providers who agree to provide services at discounted rates in return for prompt payment and an increased volume of patients. Individuals enrolled in a PPO may accumulate out-of-pocket expenses, costs for services received outside the provider network.
Primary Care Physician:
A Primary Care Physician is a doctor who has the responsibility of overseeing and coordinating all aspects of a patient's medical care. If a patient's needs require a specialist and it is not an emergency situation, the primary care physician must provide a referral for the patient to see the specialist. Primary care physicians may also be referred to as gatekeepers.
