With that in mind, here's a list of five essential Medicare facts that all current and future recipients should know.

How to qualify for Medicare benefits

Most U.S. citizens qualify forMedicare coverage once they reach age 65, so long as they (or their spouse) earned enough work credits during their career. Full Medicare benefits kick in once 40 credits are earned, and you can earn up to one work credit per quarter. Thus, reaching the 40 credit threshold requires at least 10 years of full-time work.

Thankfully, if you do not have enoughcredits to qualify for full benefits, you are still allowed to enroll. However, your monthly premiums will likely be higher.

It's also possible to qualify for Medicare coverage prior to reaching age 65 if one of the following conditions are met:

  • You are listed as permanently disabled and have received disability benefits for at least two years.
  • You have End-Stage Renal Disease and require dialysis, or have had a kidney transplant.
  • You have Lou Gehrig's disease.

How to sign up

If you're already receiving Social Security or Railroad Retirement Board benefits prior to age 65, then you won't have to do a thing -- you'll automatically be enrolled in Medicare, and you can expect to receive your card three months prior to your 65th birthday. The same is true if you meet one of the special conditions listed above.

For everyone else, you can sign up for Medicare benefits during the seven-month window that starts three months prior to your 65th birthday. If youfail to enroll during this period, then you can sign up during the general enrollment period that runs from January 1 through March 31 of each year, but your premiums will likely be higher. That's why it's important to sign up for Medicare benefits as soon as you qualify.

What it will cost you

While Medicare is generallyinexpensive, it isn't completely free. That can come as a shock to some recipients, so it's important to have a good idea of what your costs will be ahead of time.

Medicare Part A, which coversinpatient services like trips to the hospital, is free if you or your spouse earned enough work credits to qualify. However, if you wind up using the benefit, then you'll be responsible for the first $1,288 of hospital expenses as part of the deductible. There could also be additional costs for co-payments, or if your stay last longer than 60 days.More details of Part A costs and coverage can be foundhere.

Medicare Part B, which covers the costs of services and supplies needed to diagnose and treat diseases, does require a monthly premium payment. The costs for most recipients in 2016 is $104.90 per month, but there's also an annual deductible of $166 to consider. After the deductible is met, you'll generally pay a 20% copayment on any Medicare-approved products and services.

Medicare Part C, which is known as your Medicare Advantage benefit, is not provided through thegovernmentdirectly. Instead, it is provided byprivate health insurers. As such, the costs for each plan will vary greatly based on a wide number factors. You can get an idea of those costs by using Medicare'sPlan Findertool.
