Health care is one of the toughest financial challenges you'll face in retirement. For millions of retirees, Medicare coverage that takes effect for most people at age 65 is the key to being able to afford health care costs that would otherwise quickly sap their retirement savings.

But over the years, Medicare has gotten increasingly complicated, and with the emergence of Obamacare, Americans are struggling to understand exactly how to get their health care covered.
To help you get a handle on Medicare, let's run through the different types of coverage the program provides.

The Medicare Alphabet

Since 1965, Medicare's two original components have helped cover basic health needs.

The first, known as Part A, focuses on the costs of health care at medical facilities, providing coverage for medically necessary care at hospitals while you're receiving inpatient care. Under some circumstances, it also covers costs for home health services, hospice care, and skilled nursing facilities. However, nursing home costs are covered only for limited purposes and time periods.

Medicare Part B covers the costs of health care outside medical facilities, such as doctors' visits, outpatient procedures, and lab tests. It also helps cover the cost of services related to health care, such as wheelchairs and scooters, oxygen tanks, and ambulance services. In addition to providing coverage for health care needs that qualify as medically necessary, Part B also covers certain preventive-care services, such as screening for heart conditions, diabetes, and certain types of cancer.

In addition to government-provided Parts A and B, Medicare Part C is optional private insurance that Humana (HUM), Aetna (AET), UnitedHealth (UNH), and others provide. Better known as Medicare Advantage Plans, Part C involves paying premiums to those insurers, which then provide coverage for charges that Parts A and B don't pay for. Medicare Advantage Plans vary greatly both in cost and in scope of coverage, so you have to look closely at all your options to make sure they fit what you want from a plan.

Finally, Medicare Part D provides prescription drug coverage. Like Medicare Advantage Plans, Part D plans are offered through private insurance companies, and the coverage that different policies offer can vary widely from insurer to insurer and from plan to plan. In fact, many Part C Medicare Advantage Plans include Part D options within a single package.

How You Pay for Medicare

Each part of Medicare has different charges associated with it. For Part A, those who've had Medicare taxes withheld from their pay for at least 40 calendar quarters during their lifetime are eligible for free coverage.

Part B coverage requires a monthly premium that varies depending on your income level. Individuals with yearly income in 2011 of $85,000 or less, or joint tax-return filers with $170,000 or less in income, all pay $104.90 in monthly premiums for Part B. Above those levels, premiums are higher, topping out at $335.70 per month for incomes above $214,000 for singles and $428,000 for joint filers.

Private insurance for Medicare Advantage and prescription drug coverage involves paying monthly premiums to the insurers that provide your policy. What you'll pay in premiums depends in large part on the extent of the coverage the policy provides, with more all-inclusive policies charging higher monthly premiums.

In addition to premiums, you may also be responsible for deductibles, copayments, and other costs. For instance, hospital stays and covered skilled-nursing care often requires a per-day copayment from the patient.

Adding It All Together

Medicare is a complex system that has many interlocking parts. By understanding how they all work, however, you'll be in the best position to get everything you're entitled to receive under Medicare.

Medicare Explained: Understanding the Basics from Part A to Part D
Nearly 25 percent of all income taxes go to pay for defense. Of that amount, salaries and benefits for members of the armed services make up roughly a quarter, while most of the remainder goes toward equipment and supplies as well as weapons, construction, and research and development.
About 22.5 percent of income tax revenue goes toward health care programs. The two big expenditures are for Medicare and Medicaid, but additional amounts go toward health research, food safety, and public health services and disease control. These amounts don't include the dedicated Medicare taxes that workers have withheld from their pay.
The government spends roughly 17 percent of income tax revenue on various programs that provide money for those in need, including retirement benefits for federal employees, food and nutritional assistance, and Supplemental Security Income. The Earned Income Tax Credit and the Child Tax Credit are also funded from income tax revenue.
The national debt incurs a substantial amount of interest each year. Even at current low interest rates, about 8 percent of your income tax dollars go toward paying interest costs annually.
About 4.5 percent of spending goes to pay for various benefits for veterans. Income and housing support represent not quite half of the spending in this category, with health-care expenditures nearly as high. The remainder goes for education, training, and other benefits for former military personnel.
The majority of the 3.3 percent of income tax revenue spent on education and job training goes toward funding education through the high-school level. College financial aid, along with employment training for those with disabilities and more general job training and employment services for the broader public, take up the remainder.
Just over 2 percent of income tax revenue goes to support the nation's immigration and law enforcement programs. These expenses help fund the nation's court system, as well as federal law enforcement agencies and the federal service that implements U.S. immigration policy.
About 2 percent of revenue from income taxes is spent on various expenses related to the natural resources of the nation. About a third of that money goes toward water and land management, with the remainder funding environmental protection initiatives as well as management of the nation's energy assets and conservation efforts.
Money going toward international initiatives makes up about 1.7 percent of total income tax revenue. About half of that amount is spent on humanitarian and economic-development assistance, while the remainder is split among the costs of maintaining embassies and diplomatic missions, and providing security assistance overseas.
Just over 1 percent of income taxes go toward science-related programs. More than half of that amount goes to NASA, but additional recipients include the National Science Foundation as well as various national laboratories and other research facilities.
