Medicare is a national health insurance program created and administered by the federal government in the United States to address the medical needs of older American citizens. Medicare is available to U.S. citizens 65 years of age and older and some people with disabilities under age 65.
"Health Maintenance Organization" (HMO) An HMO delivers all health services through a network of healthcare providers and facilities. With an HMO, you may have: The least freedom to choose your health care providers The least amount of paperwork compared to other plans A primary care doctor to manage your care and refer you to specialists when you need one so the care is covered by the health plan; most HMOs will require a referral before you can see a specialist.
"Preferred Provider Organizations" (PPO) Are a type of health plan. PPOs have a network of doctors, hospitals, and other providers who have agreed to charge less for plan members. Members of the health plan have access to a list of providers in the network by name and location. With PPO coverage, you may also choose to seek care from providers that do not participate in the plan's network. However, going outside the network comes with additional costs. .
"Point of Service" (POS) is a mix between an HMO and a PPO-style health insurance policy. With a POS health plan, you have more choices than with an HMO. You may need to select a primary care provider and need a referral to see a specialist. But with a POS plan you have the choice to use doctors, hospitals, and other providers that are not in your health plan's network. However, you will have to pay more for using out-of-network providers. .
