If you plan to travel a lot or simply want to choose doctors without concerns over only picking providers on an HMO or PPO network, you might compare Medigap plans. With a supplement, you will have to buy Medicare Part D to cover most prescription medications. This may cost somewhat more, but some folks prefer to choose their drug plan separately from the rest of their medical benefits.

As a Medicare beneficiary, you may also be enrolled in other types of coverage, either through the Medicare program or other sources, such as an employer. When you first sign up for Original Medicare, you’ll fill out a form called the Initial Enrollment Questionnaire and be asked whether you have other types of insurance. It’s important to include all other types of coverage you have in this questionnaire. Medicare uses this information when deciding who pays first when you receive health-care services.
Because the federal government is legally obligated to provide Medicare benefits to older and disabled Americans, it cannot cut costs by restricting eligibility or benefits, except by going through a difficult legislative process, or by revising its interpretation of medical necessity. By statute, Medicare may only pay for items and services that are "reasonable and necessary for the diagnosis or treatment of illness or injury or to improve the functioning of a malformed body member", unless there is another statutory authorization for payment.[75] Cutting costs by cutting benefits is difficult, but the program can also achieve substantial economies of scale in terms of the prices it pays for health care and administrative expenses—and, as a result, private insurers' costs have grown almost 60% more than Medicare's since 1970.[citation needed][Original research?][76] Medicare's cost growth is now the same as GDP growth and expected to stay well below private insurance's for the next decade.[77]
Medicare also has an important role driving changes in the entire health care system. Because Medicare pays for a huge share of health care in every region of the country, it has a great deal of power to set delivery and payment policies. For example, Medicare promoted the adaptation of prospective payments based on DRG's, which prevents unscrupulous providers from setting their own exorbitant prices.[80] Meanwhile, the Patient Protection and Affordable Care Act has given Medicare the mandate to promote cost-containment throughout the health care system, for example, by promoting the creation of accountable care organizations or by replacing fee-for-service payments with bundled payments.[81]
**NY: In New York, the Excess Charge is limited to 5%; PA and OH: Under Pennsylvania and Ohio law, a physician may not charge or collect fees from Medicare patients which exceed the Medicare-approved Part B charge. Plans F and G pay benefits for excess charges when services are rendered in a jurisdiction not having a balance billing law; TX: In Texas, the amount cannot exceed 15% over the Medicare approved amount or any other charge limitation established by the Medicare program or state law. Note that the limiting charge applies only to certain services and does not apply to some supplies and durable medical equipment; VT: Vermont law generally prohibits a physician from charging more than the Medicare approved amount. However, there are exceptions and this prohibition may not apply if you receive services out of state.
Medicare has four parts: loosely speaking Part A is Hospital Insurance. Part B is Medical Services Insurance. Medicare Part D covers many prescription drugs, though some are covered by Part B. In general, the distinction is based on whether or not the drugs are self-administered but even this distinction is not total. Public Part C Medicare health plans, the most popular of which are branded Medicare Advantage, are another way for Original Medicare (Part A and B) beneficiaries to receive their Part A, B and D benefits; simply, Part C is capitated fee and Original Medicare is fee for service. All Medicare benefits are subject to medical necessity.
It is best to enroll in a Medigap plan during your six-month Medigap Open Enrollment Period starting the first day of the month you are 65 or older and are enrolled in Medicare Part B. During this time, you may enroll in any Medicare Supplement Insurance plan in Michigan, even if you have health problems. No medical underwriting is required, premiums are not higher based on pre-existing conditions*, and you have the guaranteed issue right to enroll in a plan of your choosing.

Robert M. Ball, a former commissioner of Social Security under President Kennedy in 1961 (and later under Johnson, and Nixon) defined the major obstacle to financing health insurance for the elderly: the high cost of care for the aged combined with the generally low incomes of retired people. Because retired older people use much more medical care than younger employed people, an insurance premium related to the risk for older people needed to be high, but if the high premium had to be paid after retirement, when incomes are low, it was an almost impossible burden for the average person. The only feasible approach, he said, was to finance health insurance in the same way as cash benefits for retirement, by contributions paid while at work, when the payments are least burdensome, with the protection furnished in retirement without further payment.[97] In the early 1960s relatively few of the elderly had health insurance, and what they had was usually inadequate. Insurers such as Blue Cross, which had originally applied the principle of community rating, faced competition from other commercial insurers that did not community rate, and so were forced to raise their rates for the elderly.[98]
