Medicare
​Medicare Part A hospital insurance covers inpatient hospital care, skilled nursing facility, hospice, lab tests, surgery, home health care.  Medicare Part B (Medical Insurance) covers medical expenses incurred while not being treated as inpatient in a hospital, including doctor and other health care providers' services and outpatient care. Part B also covers durable medical equipment, home health care, and some preventive services.
Generally, a Medicare health plan is offered by a private company that contracts with Medicare to provide Medicare Part A (Hospital Insurance) and Medicare Part B (Medical Insurance) benefits to people who enroll in the plan.
Medicare health plans include:
Medicare Advantage Plans 
Medicare Supplement Plans
Medicare Advantage Plans are another way to get your Medicare Part A and Part B coverage. Medicare Advantage Plans, sometimes called “Part C” or “MA Plans,” are offered by Medicare-approved private companies that must follow rules set by Medicare. Most Medicare Advantage Plans include drug coverage (Part D). In many cases, you’ll need to use health care providers who participate in the plan’s network and service area for the lowest costs. These plans set a limit on what you’ll have to pay out-of-pocket each year for covered services, to help protect you from unexpected costs. Some plans offer out-of-network coverage, but sometimes at a higher cost. Remember, you must use the card from your Medicare Advantage Plan to get your Medicare-covered services. Keep your red, white, and blue Medicare card in a safe place because you’ll need it if you ever switch back to Original Medicare. Below are the most common types of Medicare Advantage Plans. 
Other less common types of Medicare Advantage Plans that may be available include HMO Point of Service (HMOPOS) Plans and a Medicare Medical Savings Account (MSA) Plan.
Medigap is Medicare Supplement Insurance that helps fill "gaps" in Original Medicare and is sold by private companies. Original Medicare pays for much, but not all, of the cost for covered health care services and supplies. A Medicare Supplement Insurance (Medigap) policy can help pay some of the remaining health care costs, like:
  • Copayments
  • Coinsurance
  • Deductibles
 
 
MEDICARE PRESCRIPTION DRUG PLANS (PDP):
  • Medicare Part D, also called the Medicare prescription drug benefit, is an optional United States federal-government program to help Medicare beneficiaries pay for self-administered prescription drugs through prescription drug insurance premiums.
