Original Medicare (Part A and Part B)

Medicare Part A (Hospital Insurance)

Medicare Part A, also known as hospital insurance, covers inpatient hospital stays, skilled nursing facility care, hospice care, and some home health services. Let’s take a closer look at each aspect:


Inpatient Care:

Medicare Part A provides coverage for hospital stays, including critical access hospitals and psychiatric hospitals. This coverage includes necessary services such as meals, nursing, and medications during your stay.

It also covers semi-private rooms, although you may have to pay a deductible. 2.

Skilled Nursing Facility Care:

Part A also covers skilled nursing facility care following a qualifying hospital stay of at least three days. This benefit can be a great option for those who require extra care or rehabilitation services before returning home.

However, it’s important to note that not all services or stays in a nursing facility are covered. 3.

Hospice Care:

Medicare Part A covers hospice care for individuals diagnosed with a terminal illness and have a life expectancy of six months or less. This comprehensive program provides medical services, pain management, counseling, and support for both the patient and their family.

Medicare will cover most services related to hospice care, although you may need to pay a small copayment for prescriptions. 4.

Home Health Care:

Part A also includes limited coverage for home health care services. This benefit allows eligible individuals to receive medically necessary care in their homes, such as nursing care, physical therapy, and medical equipment.

To qualify, you must meet specific criteria and have a plan of care established by your doctor.

Medicare Part B (Medical Insurance)

Medicare Part B covers a wide range of medical services, including doctor visits, outpatient care, preventive services, and some prescription drugs. Take a closer look at the coverage offered:


Doctor Visits:

Medicare Part B covers visits to doctors, specialists, and other healthcare providers. This coverage includes diagnostic tests, X-rays, and lab work.

You may need to pay an annual deductible, and typically, Medicare will cover 80% of the approved amount for these services.


Outpatient Services:

Part B also covers a variety of outpatient services, such as ambulance services, outpatient surgeries, and mental health care. Coverage also includes durable medical equipment like wheelchairs, walkers, or oxygen supplies.

As with doctor visits, you will generally be responsible for 20% of the approved costs after meeting your deductible. 3.

Preventive Services:

Medicare Part B emphasizes preventive care, offering coverage for screenings, vaccines, and counseling to help prevent illnesses and detect conditions early on. These preventive services include flu shots, mammograms, colonoscopies, and diabetic screenings.

These services are vital for maintaining good health and preventing serious illnesses. 4.

Prescription Drugs:

While Part B covers certain prescription drugs administered in outpatient settings, it does not typically cover prescription medications you can take at home. For prescription drug coverage, you can consider Medicare Part D, which we will discuss in another section.

Medicare Advantage (Part C)

Overview of Medicare Advantage

Medicare Advantage, also known as Part C, provides an alternative to Original Medicare (Part A and Part B) by offering comprehensive coverage through private insurers. Here’s what you need to know:


How Does Medicare Advantage Work? Medicare Advantage plans are offered by private insurance companies approved by Medicare.

These plans must cover all the benefits provided by Original Medicare, but often include additional benefits, such as vision care, dental care, and hearing care. Part C plans typically have networks of healthcare providers, and you may need to choose a primary care doctor and obtain referrals for specialist visits.

2. Types of Medicare Advantage Plans:

Medicare Advantage plans include Health Maintenance Organization (HMO), Preferred Provider Organization (PPO), and Private Fee-for-Service (PFFS) plans.

Each plan type has different guidelines for coverage and costs, so it’s important to understand the specifics before enrolling.

Additional Benefits and Costs of Medicare Advantage

In addition to the standard coverage provided by Original Medicare, Medicare Advantage plans often offer extra benefits and cost help:

1. Additional Benefits:

Medicare Advantage plans may include additional benefits not covered by Original Medicare, such as prescription drug coverage, vision care, dental care, hearing care, and even fitness programs.

These extra perks can enhance your healthcare experience and provide comprehensive coverage, especially for services that are not covered under Original Medicare. 2.

Cost Help:

Medicare Advantage plans typically have out-of-pocket limits, which means once you reach a certain spending threshold in a calendar year, the plan covers all additional costs for covered services. This can provide financial protection and peace of mind, especially for individuals with chronic conditions or high medical expenses.

It is important to note that Medicare Advantage plans can have different premium structures, copayments, and deductibles depending on the specific plan and insurer. Comparing plans and understanding the costs involved is essential when choosing the right Medicare Advantage plan for your needs.

In conclusion, understanding the details of Medicare coverage is essential when navigating the healthcare system. By familiarizing yourself with the different parts of Medicare and their specific coverages, you will be equipped to make informed decisions about your healthcare needs.

Whether you opt for Original Medicare (Part A and Part B) or choose to explore additional benefits through Medicare Advantage (Part C), the goal is to ensure that you receive the necessary care and support for a healthy and fulfilling life.

Medicare Part D (Prescription Drugs)

Overview of Medicare Part D

Medicare Part D is the prescription drug coverage program available to Medicare beneficiaries. It is designed to help individuals with the cost of their prescription medications.

Here’s what you need to know about Part D:

1. How Does Medicare Part D Work?

Medicare Part D is offered through private insurance companies that are approved by Medicare. These plans provide coverage for both brand-name and generic prescription medications.

It is important to note that Part D plans have their own formularies, which are lists of covered drugs. These formularies may vary between plans, so it’s crucial to review the specifics of each plan to ensure your necessary medications are covered.

2. Enrollment in Medicare Part D:

Medicare beneficiaries can enroll in either standalone Part D plans or Medicare Advantage plans that include prescription drug coverage (Part C).

Enrollment typically occurs during the Initial Enrollment Period when you first become eligible for Medicare, during the Annual Enrollment Period, or during a Special Enrollment Period if you qualify.

Late Enrollment Penalty and Coverage

Understanding the late enrollment penalty and coverage details of Medicare Part D is crucial for making informed decisions about prescription drug coverage:

1. Late Enrollment Penalty:

If you do not enroll in a Part D plan when you first become eligible for Medicare and you go without creditable prescription drug coverage (coverage that is expected to pay, on average, at least as much as standard Medicare prescription drug coverage), you may face a late enrollment penalty.

This penalty is added to your premium and can be a long-term additional cost. It’s important to avoid this penalty by enrolling in a Part D plan during your Initial Enrollment Period if you do not have creditable coverage.

2. Coverage and Costs:

Medicare Part D plans must cover a wide range of prescription drugs, but the specific coverage and costs can vary between plans.

Each Part D plan will have its own list of covered drugs (formulary) and may also have restrictions such as prior authorization or quantity limits for certain medications. When reviewing Part D plans, it’s essential to compare the drugs you take with each plan’s formulary to ensure your medications are covered.

Additionally, Medicare Part D plans typically have premiums, deductibles, and varying levels of cost-sharing, such as copayments or coinsurance. It’s important to carefully review these costs when selecting a plan to ensure it aligns with your medication needs and budget.

Medigap (Medicare Supplement Insurance)

to Medigap

Medigap, also known as Medicare Supplement Insurance, is additional health insurance that can be purchased from private insurance companies to help fill gaps in Original Medicare coverage. Here’s what you should know about Medigap:


How Does Medigap Work? Medigap policies work alongside Original Medicare (Part A and Part B) to help cover certain costs, such as deductibles, coinsurance, and copayments.

Medigap plans are standardized and labeled with letters (A, B, C, D, F, G, K, L, M, and N). Each standardized plan offers the same basic benefits, regardless of the insurance company offering it.

However, premiums can vary between insurance companies. 2.

Enrollment in Medigap:

You can enroll in a Medigap plan during your Medigap Open Enrollment Period, which lasts for six months and begins on the first day of the month in which you turn 65 or older and enroll in Medicare Part B. During this period, you have guaranteed issue rights, meaning insurance companies must sell you a Medigap policy regardless of your health history.

If you miss this open enrollment period, insurance companies can use medical underwriting to determine your eligibility and may deny coverage or charge higher premiums based on your health.

Coverage and Limitations of Medigap

Understanding the coverage and limitations of Medigap policies is crucial for making informed decisions about supplemental insurance:

1. Coverage:

Medigap policies generally cover some or all of the following costs:

– Medicare Part A coinsurance and hospital costs up to an additional 365 days after Medicare benefits are exhausted.

– Medicare Part B coinsurance or copayments. – Blood transfusions (first three pints).

– Hospice care coinsurance or copayments. – Skilled Nursing Facility coinsurance.

– Some plans may also cover Part A and/or Part B deductibles. 2.


It’s important to note that Medigap policies do not usually cover prescription drugs (Part D). To obtain prescription drug coverage, you would need to enroll in a standalone Part D plan.

Additionally, Medigap policies generally do not cover vision, dental, hearing care, or long-term care. If you require coverage for these services, you may want to consider enrolling in a separate supplemental insurance plan or explore Medicare Advantage plans.

In conclusion, understanding Medicare Part D and Medigap is essential for comprehensive healthcare coverage. Part D helps cover the costs of prescription medications, while Medigap can help fill the gaps in coverage left by Original Medicare.

By choosing the right plans for your needs, you can ensure that you have the necessary coverage to maintain good health and financial security.

Enrolling in Medicare

Automatic Enrollment and Eligibility

Understanding automatic enrollment and eligibility requirements for Medicare is crucial for ensuring timely coverage:

1. Automatic Enrollment:

For most individuals, automatic enrollment in Medicare begins once they reach the age of 65 and are already receiving Social Security benefits.

In this case, you will be automatically enrolled in Medicare Parts A and B, which make up Original Medicare. You will receive your Medicare card in the mail approximately three months before your 65th birthday.

If you decide to keep Part B, you will need to pay the monthly premium. 2.

Turning 65:

If you are not receiving Social Security benefits when you turn 65, you will need to take the initiative to enroll in Medicare. This can be done during your Initial Enrollment Period, which begins three months before the month you turn 65 and ends three months after the month you turn 65.

Medicare Enrollment Periods and Options

Understanding the different enrollment periods and options available is essential for ensuring proper coverage:

1. Initial Enrollment Period (IEP):

The Initial Enrollment Period is an essential enrollment period that allows you to sign up for Medicare when you are first eligible.

It lasts for seven months and includes the three months before, the month of, and the three months after your 65th birthday. Failing to enroll during this period may result in a late enrollment penalty or delays in coverage.

2. General Enrollment Period (GEP):

The General Enrollment Period occurs annually from January 1st to March 31st.

During this period, individuals who did not enroll in Part A and/or Part B during their Initial Enrollment Period have another chance to enroll. However, there may be late enrollment penalties associated with delayed enrollment.

3. Special Enrollment Period (SEP):

Special Enrollment Periods are available to individuals who experience specific life events, such as losing employer-provided coverage, moving to a new location, or qualifying for other government assistance programs.

These periods provide an opportunity to enroll in or make changes to your Medicare coverage outside of the standard enrollment periods. 4.

Open Enrollment Period (OEP) for Medicare Advantage and Medicare Part D:

The annual Open Enrollment Period, also known as the Annual Election Period (AEP), is from October 15th to December 7th. During this time, individuals can make changes to their Medicare Advantage or Medicare Part D coverage.

This includes switching between plans or enrolling in a new plan to better meet their healthcare needs and budget. What Medicare Doesn’t Cover

Long-Term Care and Excluded Expenses

Understanding what Medicare doesn’t cover can help individuals plan for additional healthcare needs:

1. Long-Term Care:

Medicare does not typically cover long-term care or custodial care, which is assistance with activities of daily living, such as bathing, dressing, or eating.

This type of care is often provided in nursing homes, assisted living facilities, or through home care services. To cover long-term care costs, individuals may need to explore other options, such as long-term care insurance or Medicaid.

2. Excluded Expenses:

Medicare may not cover certain services or items, leading to out-of-pocket expenses for beneficiaries.

These exclusions include routine dental care, vision care, hearing aids, cosmetic surgeries, and acupuncture. It’s essential to review your Medicare coverage and consider supplemental insurance options, such as Medigap or Medicare Advantage plans, to help cover these excluded services.

Medicare vs. Medicaid

Understanding the differences between Medicare and Medicaid is crucial for individuals who may be eligible for both programs:



Medicare is a federal health insurance program primarily designed for individuals aged 65 and older, as well as those with certain disabilities. Funding for Medicare comes from payroll taxes, premiums, and government contributions.

Medicare helps cover some medical services, but it does not typically cover all expenses. 2.


Medicaid, on the other hand, is a joint federal and state program that provides healthcare coverage to low-income individuals and families. Eligibility for Medicaid is based on income and other factors, such as age or disability.

Medicaid covers a broader range of services, including long-term care, that Medicare does not typically cover. Medicaid benefits vary by state, and individuals may be eligible for both Medicare and Medicaid simultaneously, referred to as dual-eligible.

In conclusion, enrolling in Medicare is an important step in securing healthcare coverage for eligible individuals. Understanding the enrollment periods, eligibility requirements, and coverage options available is crucial for making informed decisions about your healthcare needs.

Additionally, being aware of what Medicare does not cover and the differences between Medicare and Medicaid helps individuals plan for potential out-of-pocket expenses and explore additional assistance programs. By navigating the Medicare landscape with knowledge and understanding, you can ensure that you have the necessary coverage and support to maintain your health and well-being.

In conclusion, understanding the intricacies of Medicare is essential for individuals approaching the age of 65 and those with certain disabilities. This comprehensive guide has provided an overview of Medicare, including its different parts (A, B, C, and D), coverage, costs, enrollment periods, and what is not covered.

From automatic enrollment and eligibility to supplemental options like Medicare Advantage and Medigap, we have explored how individuals can navigate the complexities of healthcare coverage. It is important to remember that making informed decisions about enrollment and understanding what Medicare does and does not cover can greatly impact one’s access to healthcare and financial well-being.

As you approach eligibility or consider enrollment options, take the time to explore your choices, seek guidance when needed, and ensure that you have the coverage necessary to protect your health and future.
