Medicare

Medicare Basics, Explained

What is Medicare? 

Medicare is a federal health insurance program in the United States that

provides coverage for eligible individuals, including those who are 65

years old or older, certain younger individuals with disabilities, and

individuals with end-stage renal disease. Medicare was created to provide

a federally funded health insurance program specifically for individuals

aged 65 and older, regardless of their income or medical history. 

Over the years, Medicare has played a crucial role in improving healthcare

access and financial security for millions of people. It continues to evolve

and adapt to the changing healthcare landscape, ensuring that eligible

individuals have access to essential medical services and treatments.

Medicare remains a cornerstone of the healthcare system, providing vital

support to older adults and individuals with disabilities.  

Medicare Eligibility  

  • Most individuals 65 and over are eligible for Medicare 

  • Some people under 65 are eligible too if they have certain

    disabilities or illnesses 

Medicare eligibility is primarily based on age, with most people aged 65

and over being eligible for the program. When individuals turn 65, they

become eligible for Medicare as long as they meet certain residency and

citizenship requirements. This age requirement is rooted in the original

intent of Medicare, which aimed to provide healthcare coverage for senior

citizens who often face increased healthcare needs as they age. 

For individuals under 65, Medicare eligibility is determined by specific

disabilities or medical conditions. This includes individuals who have been

receiving Social Security Disability Insurance (SSDI) benefits for at least 24

months. SSDI is a program that provides income support to individuals

who are unable to work due to a disability. After receiving SSDI benefits

for two years, individuals become eligible for Medicare, regardless of their

age. 

In addition to SSDI, individuals with certain medical conditions may also

qualify for Medicare under the age of 65. These conditions include end-

stage renal disease (ESRD) and amyotrophic lateral sclerosis (ALS), also

known as Lou Gehrig’s disease. Individuals with ESRD, which is permanent

kidney failure requiring dialysis or a kidney transplant, are eligible for

Medicare regardless of their age. Similarly, individuals with ALS are

automatically eligible for Medicare as soon as they start receiving disability

benefits from Social Security. 

It’s important to note that while individuals under 65 may qualify for

Medicare based on disabilities or specific medical conditions, the process

and requirements for enrollment may differ from those of individuals who

become eligible at age 65. In such cases, individuals can work with the

Social Security Administration to determine their eligibility and initiate the

Medicare enrollment process. 

Overall, Medicare provides essential healthcare coverage for millions of

aged 65 and older. It also extends its benefits to individuals under 65 who

  • meet specific disability or medical condition criteria, ensuring that they

have access to necessary healthcare services and treatments. 

What are the 4 types of Medicare? 

  • Medicare Part A: Also known as hospital insurance, Part A covers

inpatient hospital stays, skilled nursing facility care, hospice care,

and some home health services. Most people do not have to pay a

premium for Part A if they or their spouse have paid Medicare taxes

while working. 

  • Medicare Part B: Part B is medical insurance that covers outpatient

services, including doctor visits, preventive care, lab tests, medical

equipment, and some home health services. Part B requires the

payment of a monthly premium, which is typically deducted from

the individual’s Social Security benefits. 

  • Medicare Part C: Commonly referred to as Medicare Advantage, Part

C plans are offered by private insurance companies approved by

Medicare. These plans provide the same coverage as Part A and Part

B, and often include additional benefits like prescription drug

coverage and dental or vision care. Medicare Advantage plans may

have different costs and rules, and individuals who enroll in them

still need to pay their Part B premium. 

  • Medicare Part D: Part D is prescription drug coverage. This coverage

is available through private insurance companies that are approved

by Medicare. Part D helps individuals with the cost of prescription

medications and is available as a standalone plan or as part of a

Medicare Advantage plan. 

  • Medicare Supplement Insurance (Medigap): Medigap plans are

private insurance policies that help cover the “gaps” in coverage left

by Original Medicare (Part A and Part B). These plans can help pay

for out-of-pocket costs such as deductibles, coinsurance, and

copayments. Medigap plans are standardized and offered by private

insurance companies.

 

Original Medicare (Parts A & B) 

Original Medicare is the basic form of Medicare coverage that includes

Part A (hospital insurance) and Part B (medical insurance), providing

essential healthcare services for eligible individuals aged 65 and older or

those with certain disabilities. 

What is not covered by Original Medicare? 

  • Original Medicare does not cover: 

  • Most prescription drugs 

  • Long-term care 

  • Routine dental care or dentures 

  • Routine vision care 

  • Routine hearing care or hearing aids 

  • Routine foot care 

  • Other alternative treatments. 

Original Medicare does not cover everything, but there are Medicare Plans

that offer additional benefits that cover dental, vision and hearing. 

What is Medicare Part C (Medicare Advantage)? 

Medicare Part C, also known as Medicare Advantage, is an alternative way

for beneficiaries to receive their Medicare benefits through private

insurance companies approved by Medicare. These plans offer all the

coverage provided by Original Medicare (Part A and Part B) and often

include additional benefits such as vision, dental, and hearing

services. Medicare Advantage plans may also have different cost

structures and provider networks compared to Original Medicare,

providing beneficiaries with more options and flexibility in their healthcare

coverage. 

What is Medicare Supplement (Medigap)? 

Medicare Supplement, also known as Medigap, is a type of private health

insurance that helps fill the coverage gaps in Original Medicare. Medigap

plans are offered by private insurance companies and work alongside

Medicare to provide additional benefits and financial protection. These

plans help cover expenses such as deductibles, copayments, and

coinsurance that are not fully covered by Original Medicare. It’s important

to note that Medigap plans do not include prescription drug coverage.

Therefore, if you have a Medigap plan, you’ll need to enroll in a separate

Medicare Part D plan for prescription drug coverage. Having a Medicare

Supplement plan can provide peace of mind by reducing out-of-pocket

costs and giving you more predictable healthcare expenses. 

How do I enroll in Medicare? 

Enrolling in Medicare involves several steps and options, depending on

your specific situation. Here is an outline of the enrollment process,

including information about automatic enrollment, initial enrollment

periods, special enrollment periods, and late enrollment penalties: 

1. Automatic Enrollment: 

  • If you are already receiving Social Security benefits or Railroad

    Retirement Board (RRB) benefits, you will be automatically

    enrolled in Medicare Part A (Hospital Insurance) and Part B

    (Medical Insurance) when you turn 65. 

  • You will receive your Medicare card in the mail about three

    months before your 65th birthday. 

2. Initial Enrollment Period (IEP): 

  • If you are not automatically enrolled, you have an Initial

    Enrollment Period to sign up for Medicare. The IEP lasts for 7

    months and begins three months before the month you turn

    65, includes your birthday month, and ends three months

    after your birthday month. 

3. Enrolling in Part A and Part B: 

  • You can enroll in Medicare Part A and/or Part B in the following

    ways: 

  • Online: Visit the Social Security Administration (SSA) website

    and complete the application. 

  • Phone: Call the SSA at 1-800-772-1213 (TTY 1-800-325-0778)

    and apply over the phone. 

  • In-person: Visit your local SSA office and apply in person. 

4. Special Enrollment Period (SEP): 

  • If you missed your Initial Enrollment Period, you may be

    eligible for a Special Enrollment Period. 

  • SEPs are triggered by certain life events, such as losing

    employer-based coverage, moving, or qualifying for Medicaid. 

  • You typically have 8 months to enroll in Medicare after the

    qualifying event. 

5. Late Enrollment Penalties: 

  • If you don’t enroll in Medicare Part B when you are first eligible

    and you don’t have other creditable coverage (e.g., employer-

    based coverage), you may have to pay a late enrollment

    penalty. 

  • The penalty is added to your Part B premium and increases

    your monthly premium for as long as you have Part B. 

  • The penalty amount depends on how long you delayed

    enrollment, and it may increase over time. 

It’s essential to understand the enrollment periods and options to ensure

timely and proper enrollment in Medicare. If you have any questions or

need assistance, you can contact the Social Security Administration or visit

their website for more detailed information. 

Automatic Enrollment 

If you are already receiving Social Security benefits or Railroad Retirement

Board (RRB) benefits, you will be automatically enrolled in Original

Medicare when you turn 65. This includes Medicare Part A (Hospital

Insurance) and Part B (Medical Insurance). However, you have the option

to delay enrollment in Part B if you have other health insurance coverage,

such as through an employer or union. In such cases, you can choose to

decline Part B and enroll later without facing a late enrollment penalty. It’s

essential to carefully consider your existing coverage and consult with

your employer or benefits administrator to understand how your current

insurance interacts with Medicare. 

If you are not receiving Social Security benefits, you need to take steps to

enroll in Original Medicare.  

Here are the options: 

  • Enroll online: You can visit the official Social Security website and

    complete the Medicare application online. This process is

    straightforward and allows you to conveniently submit your

    application. 

  • Enroll by phone: You can call the Social Security Administration at 1-

    800-772-1213 (TTY 1-800-325-0778) and speak with a representative

    who can guide you through the enrollment process. They will assist

    you in completing the application over the phone. 

  • Enroll in person: If you prefer a face-to-face interaction, you can visit

    your local Social Security office and apply for Medicare in person.

    The staff at the office will provide you with the necessary forms and

    help you complete the application. 

It’s important to note that if you delay enrolling in Part B without having

other creditable coverage (such as employer-based insurance), you may

face a late enrollment penalty. This penalty can result in a higher monthly

premium for Part B, and it will apply for as long as you have Part B

coverage. 

It’s advisable to understand your options and the timing of your

enrollment to ensure you have the appropriate coverage when you need

it. If you have any questions or need assistance with the enrollment

process, you can contact the Social Security Administration or visit their

website for more information. 

Medicare Enrollment Periods 

Initial Enrollment Period (IEP):  The Initial Enrollment Period is the first

opportunity for individuals to enroll in Medicare. It occurs when you first

become eligible for Medicare, typically around your 65th birthday. The IEP

lasts for seven months and includes the three months before your 65th

birthday, the month of your birthday, and the three months after. 

During your IEP, you have several enrollment options: 

 Original Medicare (Part A and Part B): You can enroll in Original

Medicare, which includes hospital insurance (Part A) and medical

insurance (Part B). 

 Medicare Advantage (Part C): You can choose to enroll in a Medicare

Advantage plan offered by private insurance companies. These

plans provide Medicare Part A and Part B coverage, often with

additional benefits such as prescription drug coverage. 

 Prescription Drug Coverage (Part D): If you opt for Original Medicare,

you can also enroll in a standalone Medicare Part D prescription

drug plan to help cover the cost of medications. 

Medicare Advantage Open Enrollment Period (MA OEP): The Medicare

Advantage Open Enrollment Period is an annual period during which

individuals who are already enrolled in a Medicare Advantage plan can

make changes to their coverage. This period takes place from January 1st

to March 31st each year. During this period, it’s recommended to review

your current Medicare Advantage plan and compare it with other available

options to ensure that you have the coverage that best meets your needs. 

During the MA OEP, individuals who are enrolled in a Medicare Advantage

plan can do the following: 

 Switch to a different Medicare Advantage plan: You can switch from

one Medicare Advantage plan to another, which may offer different

benefits, costs, or provider networks. 

 Disenroll from a Medicare Advantage plan and return to Original

Medicare: If you decide that a Medicare Advantage plan is not the

right fit for you, you can disenroll and return to Original Medicare.

You will have the option to add standalone Medicare Part D

prescription drug coverage if needed. 

It’s important to note that the Medicare Advantage Open Enrollment

Period is specifically for individuals who are already enrolled in a Medicare

Advantage plan. It does not apply to individuals who are enrolled in

Original Medicare without a Medicare Advantage plan.  

Medicare Supplement Open Enrollment Period (Med Supp

OEP):  Medicare Supplement Open Enrollment Period (Med Supp OEP):

The Medicare Supplement Open Enrollment Period is a six-month period

that begins when you are both 65 years old and enrolled in Medicare Part

B. During this time, you have the opportunity to purchase any Medicare

Supplement (Medigap) policy available in your state, regardless of your

health condition. 

Here’s what you need to know about the Med Supp OEP: 

 Guaranteed Issue Right: During the Med Supp OEP, insurance

companies cannot deny you coverage or charge you higher

premiums based on your health status. This is known as your

guaranteed issue right. 

 Freedom to Choose: You have the freedom to choose any Medicare

Supplement plan available in your area. These plans are labeled with

letters (such as Plan A, B, C, etc.) and each plan offers different

benefits to supplement your Original Medicare coverage. 

 No Medical Underwriting: Insurance companies cannot require you

to undergo medical underwriting during the Med Supp OEP. This

means they cannot ask you about your pre-existing conditions or

deny you coverage based on your health. 

It’s important to take advantage of the Med Supp OEP because once this

period ends, insurance companies can consider your health status and

medical history when deciding whether to offer you a Medicare

Supplement policy and at what price. If you miss this enrollment period,

you may still be able to apply for a Medicare Supplement plan, but you

could face medical underwriting and potentially higher premiums. 

Special Enrollment Period (SEP): The Special Enrollment Period (SEP) is a

time outside of the initial enrollment period when you may be eligible to

enroll in Medicare or make changes to your existing Medicare coverage.

SEPs are granted for specific circumstances, allowing you to enroll or

make changes outside of the standard enrollment periods. 

Here are some common situations that may qualify you for a Special

Enrollment Period: 

 Delayed Retirement: If you delayed your retirement past the age of

65 and had healthcare coverage through your employer or union,

you may be eligible for an SEP when you retire and lose your existing

coverage. 

 Loss of Employer Coverage: If you had employer-sponsored health

insurance and it is no longer available to you (e.g., due to job loss or

retirement), you may be eligible for an SEP to enroll in Medicare. 

 Moving: If you move outside of your current Medicare plan’s service

area, you may be eligible for an SEP to select a new plan that serves

your new location. 

 Dual Eligibility: If you are eligible for both Medicare and Medicaid,

you may have additional opportunities to make changes to your

coverage through an SEP. 

 Qualifying Life Events: Certain life events, such as marriage, divorce,

or the death of a spouse, may trigger an SEP. 

It’s important to be aware of the specific requirements and timelines for

each SEP. Generally, you will have a limited window of time to take

advantage of the SEP, typically around 60 days from the qualifying event.

During this time, you can enroll in or make changes to your Medicare

coverage without facing penalties or restrictions. 

Annual Election Period (AEP):  The Annual Election Period (AEP), also

known as the Open Enrollment Period, is a designated time each year

when Medicare beneficiaries can make changes to their Medicare

Advantage (Part C) and Medicare prescription drug (Part D) plans. 

During the AEP, which runs from October 15th to December 7th, you have

the following options: 

Switch Medicare Advantage plans:  

 You can change from one Medicare Advantage plan to another, or

you can switch from Original Medicare to a Medicare Advantage

plan. 

 Enroll in a Medicare Advantage plan: If you are currently enrolled in

Original Medicare, you can use the AEP to enroll in a Medicare

Advantage plan that offers additional benefits. 

 Join a Medicare prescription drug plan: If you have Original Medicare

and want prescription drug coverage, you can enroll in a Medicare

Part D prescription drug plan. 

 Change your Medicare prescription drug plan: If you already have a

Medicare Part D plan, you can switch to a different plan that better

suits your needs. 

It’s important to note that any changes made during the AEP will take

effect on January 1st of the following year. This is a crucial period to

review your current Medicare coverage, assess your healthcare needs,

and make any necessary adjustments to ensure you have the most

suitable coverage for the upcoming year. 

History of Medicare 

Medicare was signed into law on July 30, 1965, by President Lyndon B.

Johnson as an amendment to the Social Security Act. It was created to

provide health insurance coverage for Americans aged 65 and older,

regardless of income or medical history. The program aimed to address

the lack of affordable healthcare for seniors and to ensure they had

access to essential medical services. Since its inception, Medicare has

undergone several expansions and amendments, including the addition of

coverage for people with disabilities and those with end-stage renal

disease. Medicare has become a cornerstone of the American healthcare

system, providing millions of beneficiaries with access to essential

healthcare services and contributing to improved health outcomes for

older adults and individuals with disabilities. 

Medicare vs. Medicaid 

Medicare and Medicaid are both government programs that provide

healthcare coverage, but they serve different populations and have

different eligibility requirements. 

Medicare is a federal health insurance program primarily for people aged

65 and older, although it also covers some individuals with disabilities or

specific medical conditions. It is generally available to all U.S. citizens and

legal residents who have paid into the Medicare system through payroll

taxes. Medicare is divided into different parts: Part A covers hospital

insurance, Part B covers medical insurance, Part C offers Medicare

Advantage plans, and Part D provides prescription drug coverage.

Medicare is administered by the federal government. 

Medicaid, on the other hand, is a joint federal and state program that

provides health coverage to low-income individuals and families. Eligibility

for Medicaid is based on income and other factors, and it varies from state

to state. Medicaid is designed to assist individuals and families who have

limited financial resources and may not be able to afford private health

insurance. The program covers a wide range of medical services and is

administered by individual states, following certain federal guidelines. 

In summary, Medicare primarily serves older adults and people with

disabilities, while Medicaid focuses on providing healthcare coverage to

low-income individuals and families. The eligibility requirements, benefits,

and administration of the two programs differ, but both play important

roles in ensuring access to healthcare for different segments of the

population.
