Medicare is a national health insurance program that was implemented by the US government in the year 1965 as part of the Social Security Act. Since then Medicare has been serving elder Americans, who have reached the age of 65 and have certain disabilities, in getting proper medical care that they need and deserve.

You will qualify for Medicare under certain conditions. You must be

• 65 years or older or
• Under age 65 but with a specific disability or
• Any age but with terminal-stage renal disease

Medicare insurance is an entitlement program just like Social Security and anybody who meets the qualifying criteria for Medicare is eligible. The Medicare eligibility criteria are constant throughout America and coverage constant and independent of the state you get treated in.

Medicare benefits have been divided in 4 main parts by "The Department of Health and Human Services":

1. Medicare Part A (Hospital Insurance):
   Covers part of inpatient care in hospitals, skilled nursing facility, home health care (if you meet certain conditions) as well as hospice services. Benefit from Medicare Part A can be received beginning from the time you turn 65 if you already receive benefits from Social Security or the Railroad Retirement Board (RRB). If you are under 65 years and have some kind of disability, Part A benefits will be provided after you get disability benefits from Social Security or Railroad Retirement Board for 24 months. You will receive a Medicare card either in the mail 3 months in advance to your 65th birthday or on the 25th month of your disability.
   
   When should you enroll for Medicare Part A?
   Medicare Part A or Hospital Insurance can be bought during the period beginning 3 months prior to your 65th birthday and ending 3 months after your 65th birthday. You may also buy this insurance during January 1and March 31 every year. You may even opt for a special enrollment in case you are covered under the group health insurance plan of your spouse's employer or union.


2. Medicare Part B (Medical Insurance):
   Covers services like doctor's service and outpatient care and also a part of the preventive services that helps maintain your health and check some health conditions from worsening.
   
   When should you enroll for Medicare Part B?
   If you already get Social Security Benefits or Railroad Retirement Board (RRB) benefits then you will automatically get Part B beginning the day you turn 65. If you are under 65 and disabled, you will be entitled to certain disability benefits from Social Security or RRB for 24 months.


3. Medicare Part C (Medicare Advantage Plans):
   Private insurance companies approved by Medicare manage Part C. Medicare providers have combined hospital care, medical care and also sometimes prescription drug coverage in this plan. Such a plan can, however, charge different co-insurance premiums, co payments or deductibles compared to those charged by the government in Medicare parts A and B.
   
   Part C or which is also popularly known as the Medicare + Choice or "Medicare Advantage" plan requires that you should pay a monthly premium in addition to the fixed premium. Whenever you see a doctor you need to pay a fixed amount but for seeing a specialist you need to pay extra. This plan may be more expensive than the original Medicare plan.


4. Medicare Part D (Prescription Drug Plan): Covers part of the cost for your prescription drugs. Individual plans vary in cost and the benefits received may also differ. Prescription Drug Plan can be added with the help of private insurance companies. However, if you have Medicare Hospital insurance and Medical Insurance, you will be automatically entitled to the Prescription Drug Plan.
   
   With Medicare Part D you can pay less when buying prescription drugs. Use the Medicare ID card at any drug store and if you have limited income, you may get additional assistance with the costs.

Yes there is a Medicare supplement plan for those who feel there are significant gaps or large expenses that is associated with medical cost sharing that can later add up to a Medicare plan. Solutions to cover these gaps have been developed by the collaborative efforts of the Federal and State Governments. You can choose from different levels of coverage.

• Whether you are pregnant
• Your income and resources (bank accounts, real property or any other item that can be sold for cash)
• Whether you are disabled (blindness included)
• Whether you are a US citizen or a lawfully admitted immigrant
