Medicare is our country’s federal health insurance program for people age 65 and older, as well as some younger people with disabilities, or any age with end-stage renal disease (ESRD).
Here’s a closer look at some Medicare basics, including the parts of Medicare, eligibility, enrollment and more.
What are the parts of Medicare?
There are 4 different parts of Medicare that help cover specific services:
What are Medicare Supplement Plans?
Medicare Supplement plans, also known as Medigap, are private insurance plans that can help pay healthcare costs that Original Medicare doesn’t pay. Examples include copayments, coinsurance and deductibles.
How does Medicare work?
Original Medicare (Part A and Part B) is managed by the federal government. You’ll only need to sign up once, but each year, you can make changes to your health coverage during the Medicare Open Enrollment Period.
Your Medicare coverage choices
Once you become eligible for Medicare, you’ll need to decide how you get your coverage. Generally, there are 2 ways to get Medicare coverage:
- Original Medicare, which includes Parts A Part B only.
- Medicare Advantage, referred to as an “all-in-1” plan, bundles Parts A and B coverage and typically includes prescription drug coverage. Some Medicare Advantage plans include extra benefits that Original Medicare doesn’t cover, like dental, vision and hearing care services.
Keep in mind, if you choose Original Medicare, you’ll also want to consider prescription drug coverage (Medicare Part D) coverage and supplemental coverage (Medicare Supplement plan, also known as “Medigap”) to help manage out-of-pocket costs.

How much does Medicare cost?
Each part of Medicare has their own costs and coverage levels. Here’s a quick breakdown of common costs for each:
- Medicare Part A: Most people pay $0 for the Part A premium because they or a spouse paid Medicare taxes long enough while working (generally at least 10 years).
- Medicare Part B: In 2023, most Medicare members must pay a monthly premium of $164.90 (a decrease of $5.20 from $170.10 in 2022).
- Medicare Part C: Medicare Advantage plans are offered by private insurance companies so they vary in cost.
- Medicare Part D: Medicare prescription drug plans are offered by private insurance companies so they vary in cost.

Are you eligible for Medicare?
Original Medicare Parts A and B are available to people:
- Age 65 or older
- Younger than 65 with a qualifying disability
- With ESKD, permanent kidney failure requiring dialysis or a kidney transplant

How to enroll in Medicare
Whether you’re new to Medicare or want to change your coverage, there are certain times during the year when you can enroll. Here’s a look at each enrollment period.
Medicare Enrollment Periods
- Initial Election Period (IEP): For many people, IEP begins 3 months before you turn 65 and ends 3 months after. This is your first chance to enroll in Original Medicare.
- Initial Coverage Election Period (ICEP): ICEP begins 3 months before you become eligible for both Part A and Part B. This is when you can enroll in a Medicare Advantage plan with or without prescription drug coverage.
- Annual Election Period (AEP): Also known as “Medicare open enrollment” and “annual enrollment period”, AEP is available each year from Oct. 15 – Dec. 7 to any Medicare eligible recipient who wants to enroll or change their coverage.
- Special Election Period (SEP): SEPs are opportunities to enroll in or change a Medicare Advantage plan outside of ICEP or AEP. An SEP must be triggered by a qualifying event, like a change in residence or termination of your current plan.

Medicare vs. Medicaid
Medicaid and Medicare are 2 types of public health insurance programs. However, there are differences in availability and coverage. Medicare is open to most people ages 65 and older and to some people under 65 who have specific disabilities. People eligible for Medicare can get coverage through the federal government or through a private health insurance company like Humana.
Medicaid is open to people who meet income guidelines, qualified families and children, pregnant women, seniors and people with disabilities. People of any age can qualify to receive Medicaid benefits.
People who qualify for both Medicare and Medicaid are called “dual eligible.” If you have dual eligibility, Medicare will be your primary plan and cover most healthcare services. Your Medicaid plan will cover services and benefits that Medicare does not. Some private insurers offer dual eligible special needs plans, or D-SNPS, which are Medicare Advantage plans designed to meet the specialized needs of dual-eligible beneficiaries.
