The dual-eligible population comprises roughly 20 percent of Medicare's enrollees but accounts for 36 percent of its costs. There is substantial evidence that these individuals receive highly inefficient care because responsibility for their care is split between the Medicare and Medicaid programs—most see a number of different providers without any kind of mechanism to coordinate their care, and they face high rates of potentially preventable hospitalizations. Because Medicaid and Medicare cover different aspects of health care, both have a financial incentive to shunt patients into care the other program pays for.
Generally, the different parts of Medicare help cover specific services. Most beneficiaries choose to receive their Parts A and B benefits through Original Medicare, the traditional fee-for-service program offered directly through the federal government. It is sometimes called Traditional Medicare or Fee-for-Service (FFS) Medicare. Under Original Medicare, the government pays directly for the health care services you receive. You can see any doctor and hospital that takes Medicare (and most do) anywhere in the country.
Unless you choose otherwise, you will have Original Medicare. Instead of Original Medicare, you can decide to get your Medicare benefits from a Medicare Advantage Plan, also called Part C or Medicare private health plan. Remember, you still have Medicare if you enroll in a Medicare Advantage Plan. This means that you must still pay your monthly Part B premium (and your Part A premium, if you have one). Each Medicare Advantage Plan must provide all Part A and Part B services covered by Original Medicare, but they can do so with different rules, costs, and restrictions that can affect how and when you receive care.
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.
The Omnibus Budget Reconciliation Act of 1989 made several changes to physician payments under Medicare. Firstly, it introduced the Medicare Fee Schedule, which took effect in 1992. Secondly, it limited the amount Medicare non-providers could balance bill Medicare beneficiaries. Thirdly, it introduced the Medicare Volume Performance Standards (MVPS) as a way to control costs.
A federal law passed in 2003 created a “competition” requirement for Medicare Cost plans, which stipulated the plans could not be offered in service areas where there was significant competition from Medicare Advantage plans. Congress delayed implementation of the requirement several times until a law passed in 2015 that called for the rule to take effect in 2019.
