Medicare is a federal health insurance program for individuals aged 65 and over, as well as some younger people with specific disabilities or conditions. It is divided into several parts, each covering different services. Medicare Part B is also known as Medical Insurance and covers doctors' services, tests, and preventive services.

Part A (Hospital Insurance)

Medicare Part A, also known as Hospital Insurance, is one of the two parts of Original Medicare—the other being Part B, or Medical Insurance. Part A covers inpatient hospital care, skilled nursing facility (SNF) care, hospice care, and some home health care.

Part A covers inpatient hospital care, including hospital stays and services received in a hospital or long-term care setting. If a doctor formally admits you to a hospital, Part A will cover you for up to 90 days in your benefit period. This period begins on the day of admission and ends after you have been out of the hospital for 60 consecutive days. Once you meet your deductible, Part A will pay for days 1–60 of your hospital stay. For days 61–90, you will pay a coinsurance fee for each day. If your hospital stay exceeds 90 days, you can use up to 60 lifetime reserve days, which are extra days of Medicare coverage for extended hospital stays.

Part A also covers skilled nursing facility (SNF) care, including room and board, administering medication, and changing sterile dressings. To qualify for SNF coverage, you must first spend at least three days as an inpatient in a hospital within 30 days of being admitted to an SNF. Medicare will cover up to 100 days of SNF care per benefit period.

In addition to inpatient hospital care and SNF care, Part A also covers hospice care, which provides comfort and support for terminally ill patients. Hospice care has relatively fewer restrictions on Medicare eligibility, and as long as your provider certifies the care, Medicare will cover the cost.

Finally, Part A covers some home health care services. To qualify for Medicare coverage for home healthcare, you must require skilled care, such as services that typically require a license or medical supervision to perform, and be homebound. If you meet these criteria and have spent at least three days as a hospital inpatient within 14 days of receiving home healthcare, Part A can cover up to 100 days of home healthcare.

It is important to note that while Part A covers a range of services, there are also exclusions. For example, long-term care, dentures, and routine physical exams are not typically covered by Original Medicare. Additionally, to be eligible for Medicare coverage, you must be lawfully present in the United States, and there may be specific enrollment periods and requirements to consider.

Part B (Medical Insurance)

Medicare Part B, also known as Medical Insurance, is one of the two parts of Original Medicare, the other being Part A (Hospital Insurance). Part B helps cover medically necessary services and preventive services. Medically necessary services are those that meet accepted standards of medical practice to diagnose or treat a medical condition. Preventive services include healthcare to prevent illness (e.g. the flu) or detect it in its early stages when treatment is likely to be most effective.

Most people pay a monthly premium for Part B, and the exact premium depends on their income level. If you are in a Medicare Advantage Plan or other Medicare plan, your plan may have different rules, but it must give you at least the same coverage as Original Medicare. If you have Part B and Medicare Supplement Insurance (Medigap) that pays your Part B coinsurance, your Medigap plan should cover the cost of insulin (up to $35 or less).

You can choose to get your Medicare coverage through Original Medicare (Parts A and B) or Medicare Advantage (Part C). If you choose Original Medicare, you can also decide whether you want drug coverage (Part D) and supplemental coverage, like Medigap. If you have Medicare and other health insurance (e.g. from your job), one will be the primary payer, and the other will be the secondary payer.

Medicare Advantage (Part C)

With Medicare Advantage, you receive all of your Part A and Part B coverage through the plan, and it may also offer extra benefits such as vision, hearing, dental, and health and wellness programs. Most Medicare Advantage plans also include prescription drug coverage (Part D).

Medicare Advantage plans are available from a variety of private companies, and you can choose the one that best suits your needs. These plans must follow the rules set by Medicare, but they can have different out-of-pocket costs and rules for accessing services. For example, you may need a referral to see a specialist or be restricted to using doctors and facilities within the plan's network.

When enrolling in Medicare, you have the option to choose between Original Medicare and Medicare Advantage (Part C) for your health coverage. If you opt for Original Medicare, you can also decide whether you want drug coverage (Part D) and supplemental coverage, such as Medigap, to help with out-of-pocket costs.

It is important to note that to join a Medicare Advantage Plan, you must have both Part A and Part B. Additionally, if you are not lawfully present in the U.S., you are not eligible for Medicare Advantage.

Supplemental coverage (Medigap)

Medicare Part B is also known as Medical Insurance. This is one part of Original Medicare, which also includes Part A (Hospital Insurance).

Supplemental coverage, also known as Medigap, is an additional insurance policy that can be purchased from a private health insurance company. It helps to cover the out-of-pocket costs associated with Original Medicare, which includes Part A and Part B.

Medigap policies are generally only available to those who have Original Medicare. They can help to lower the costs of services received through Medicare, and some policies may also cover additional benefits that aren't included in Medicare.

When you buy a Medigap policy, you will need to pay a monthly premium to the insurance company, in addition to the Medicare Part B premium. The Medigap policy is guaranteed to be renewable each year as long as you continue to pay your premium. It is important to note that Medigap policies are standardized, and the benefits offered are the same regardless of which insurance company you choose.

Medigap can help provide additional coverage and reduce out-of-pocket expenses for those who are enrolled in Original Medicare. It is an optional supplement that individuals can choose to purchase to enhance their healthcare coverage.

Medicare Part D (Drug coverage)

Medicare Part D, also known as the Prescription Drug Plan, is an optional benefit for those who are enrolled in Original Medicare (Parts A and B). Part D helps cover the cost of prescription medications, including those taken regularly for chronic conditions like heart disease, high cholesterol, or asthma, as well as short-term medications like antibiotics.

There are two ways to get Part D coverage. The first is to enroll in a standalone Part D plan offered by approved private insurers. The second option is to choose a Medicare Advantage plan (Part C) that includes drug coverage. It is important to note that not all Medicare Advantage plans include drug coverage, so it is essential to review the details of any plan before enrolling.

Part D plans can vary in terms of the specific drugs they cover, the level of cost coverage, and monthly premiums. However, all Part D plans are required to provide a minimum standard level of coverage as mandated by Medicare. Additionally, Part D plans offer flexible options, allowing individuals to choose plans that best suit their needs and other coverage they may have.

It is important to enroll in a Part D plan when eligible to avoid paying a late enrollment penalty. If an individual delays enrolling, Medicare will charge a small fee for each month of delay, which is added to the monthly premium. Part D plans typically have three phases: deductible, initial coverage, and catastrophic coverage. During the initial coverage phase, individuals pay a copay or coinsurance on covered drugs until their out-of-pocket costs reach $2,000. After reaching this threshold, the individual enters the catastrophic coverage phase, where they pay nothing for the rest of the calendar year.
