Public Part C Medicare Advantage health plan members typically usually also pay a monthly premium in addition to the Medicare Part B premium to cover items not covered by traditional Medicare (Parts A & B), such as the OOP limit, self-administered prescription drugs, dental care, vision care, annual physicals, coverage outside the United States, and even gym or health club memberships as well as—and probably most importantly—reduce the 20% co-pays and high deductibles associated with Original Medicare. But in some situations the benefits are more limited (but they can never be more limited than Original Medicare and must always include an OOP limit) and there is no premium. In some cases, the sponsor even rebates part or all of the Part B premium, though these types of Part C plans are becoming rare.
Part B coverage includes out patient physician services, visiting nurse, and other services such as x-rays, laboratory and diagnostic tests, influenza and pneumonia vaccinations, blood transfusions, renal dialysis, outpatient hospital procedures, limited ambulance transportation, immunosuppressive drugs for organ transplant recipients, chemotherapy, hormonal treatments such as Lupron, and other outpatient medical treatments administered in a doctor's office. It also includes chiropractic care. Medication administration is covered under Part B if it is administered by the physician during an office visit.
As a result of these changes and other administrative choices by Centers for Medicare and Medicaid Services (CMS, per-person expenditures for beneficiaries on Parts A/B/C and those not on A/B/C reached effective parity). One such choice ended the out-of-balance PFFS plan program except for grandfathered beneficiaries. The out-of-balance Employer Group plan program was cut back beginning in 2017.
Over the long-term, Medicare faces significant financial challenges because of rising overall health care costs, increasing enrollment as the population ages, and a decreasing ratio of workers to enrollees. Total Medicare spending is projected to increase from $523 billion in 2010 to around $900 billion by 2020. From 2010 to 2030, Medicare enrollment is projected to increase from 47 million to 79 million, and the ratio of workers to enrollees is expected to decrease from 3.7 to 2.4. However, the ratio of workers to retirees has declined steadily for decades, and social insurance systems have remained sustainable due to rising worker productivity. There is some evidence that productivity gains will continue to offset demographic trends in the near future.
Sicker people and people with higher medical expenditures are more likely to switch from Medicare Advantage plans to Original Medicare. This statistic is primarily driven by people on Medicaid in custodial care at nursing home; such people no longer have need of any Medicare supplement, either a public Part C plan or a private Medigap or group retirement plan. The Part C risk adjusted payments to Medicare Advantage plans are designed to limit this churn between types of Medicare (managed vs. FFS), but it is unclear how effective that policy is.
Among those the Centers for Medicare and Medicaid Services will now allow, if they’re deemed health-related: Adult day care programs. Home aides to help with activities of daily living, like bathing and dressing. Palliative care at home for some patients. Home safety devices and modifications like grab bars and wheelchair ramps. Transportation to medical appointments.
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.
Some people don’t realize this and join Medicare Advantage plans without the help of an agent. Therefore they don’t know about all of these rules. Sometimes they find themselves enrolled into a plan that their doctor doesn’t accept or that doesn’t include one of their medications. This happens most often in January after a person has used the Annual Election Period to join a Medicare Advantage plan.
In 2015, Medicare provided health insurance for over 55 million—46 million people age 65 and older and 9 million younger people. In January 2018, they have issued the new medicare (Red, White and Blue) cards to all the beneficiaries.  On average, Medicare covers about half of the healthcare charges for those enrolled. The enrollees must then cover their remaining costs either with supplemental insurance, separate insurance, or out of pocket. Out-of-pocket costs can vary depending on the amount of healthcare a Medicare enrollee needs. These out-of-pocket costs might include deductibles and co-pays; the costs of uncovered services—such as for long-term, dental, hearing, and vision care—and supplemental insurance premiums.
