Medicare: All you need to know
What is Medicare?
When Medicare’s an option, you’ll have new insurance choices to consider. Our guide will help you figure out:
- How Medicare works
- What are the parts
- Who’s eligible
- When to enroll
- How to choose the best plan
How Medicare worksMedicare might seem complicated. But with a little knowledge, you can make the right coverage choices. Medicare has four parts: A, B, C, and D. Each one is a little different.
Medicare Part A: Hospital coverage
Medicare Part A covers your inpatient hospital care. You don’t need to pay a premium for Part A if you or your spouse worked at least 10 years.
Here are the types of hospital care that qualify for coverage.
|Part A in 2023|
$200 copay per day
All costs for each day after day 100
Medicare Part B covers your medical care. Services include doctor office visits, diagnostic tests, preventive care, medical supplies, and outpatient care. You pay a monthly premium for Part B to the federal government. Your Medicare Part B payment is usually deducted from your Social Security check. If you don’t receive Social Security, you’ll be billed quarterly.
Part B costs

Medicare pays 80% of costs for eligible services and supplies
20% after deductible
When you choose a private Medicare Advantage plan, you agree to have the plan administer your Medicare Part A and Medicare Part B benefits. Medicare Advantage plans include hospital and medical coverage. They cover some of the costs that Medicare doesn’t cover. Many also include Part D prescription drug coverage, which makes it easier for you by having all your hospital, medical, and prescription drug benefits in one plan.
Part D options
Combined coverage plans
Combined coverage plans offer Part D drug plus hospital and medical coverage like Medicare Advantage plans.
Standalone coverage plans only provide Part D prescription drug coverage.
Part D drug plans have costs like premiums, deductibles, and copays. These costs vary by plan, so it pays to shop around. Not all drugs are covered by all plans. Make sure your drugs are covered before you enroll in a plan.
Who’s eligible for Medicare?
Most people become eligible for Medicare at age 65. You don't have to be retired or collecting Social Security to be eligible. You may also be eligible before 65 if you're permanently disabled or have been diagnosed with end-stage renal disease (ESRD).
Medicare eligibility requirements:
- You must be a U.S. citizen or a permanent legal resident for at least five consecutive years
- You must also meet one or more of the following:
- You're age 65 or older
- You receive, or are eligible for, retirement benefits from Social Security or the Railroad Retirement Board
- You’re any age and have a qualifying permanent disability
- You need ongoing dialysis for end-stage renal disease (ESRD) or need a kidney transplant
If you're turning 65 soon, you can sign up during your IEP, which lasts for seven months. That seven-month time frame includes:
- The three months before you turn 65
- The month you turn 65
- The three months after you turn 65
- If you're enrolling for the first time due to disability, your IEP timing is based on your disability date.
During the IEP, you can sign up for any of the following:
- Medicare Part A (Hospital coverage)
- Medicare Part B (Medical coverage)
- Medicare Part C (private Medicare Advantage plans)
- Medicare Part D (private prescription drug plans)
If you want to be covered by Medicare during the month you turn 65, you need to sign up at least one month before your birthday month.
If you don't enroll in Medicare Part B or Part D during IEP, you may have to pay more to enroll later.
Annual Enrollment Periods
Sometimes the plan you choose isn’t the right plan for you. These annual enrollment periods allow you to make changes to your plan.
Annual Open Enrollment Period: October 15 to December 7
If you make any plan changes, they'll go into effect on January 1. During annual open enrollment, you can choose to enroll, disenroll, or change your plan choices. Here are some examples:
- Change from Original Medicare to a Medicare Advantage plan or vice-versa
- Switch from a Cost plan with Part D to another Cost plan with Part D or an alternative private plan like Medicare Advantage
- Switch from one Medicare Advantage plan to another Medicare Advantage plan or a Cost plan
- Switch from one Medicare prescription drug plan to another Medicare prescription drug plan or a Medicare Advantage plan or Cost plan with Part D
Medicare Advantage Open Enrollment Period: January 1 to March 31
If you're enrolled in a Medicare Advantage plan, you have a one-time chance to:
- Switch to a different Medicare Advantage plan
- Drop your Medicare Advantage plan and return to Original Medicare (Part A and Part B)
- Sign up for a standalone Medicare Part D prescription drug plan (if you return to Original Medicare)
Special Enrollment Periods (SEP)
An SEP lets you make coverage changes that you normally can only make during your Initial Enrollment Period (IEP) or open enrollment. There are many types of events that can trigger an SEP:
- You move outside your plan's service area
- You become eligible for Medicaid
- You qualify for extra help with Medicare prescription drug costs
- You lose prescription drug coverage from an employer or union, or your drug coverage is no longer as good as the standard Part D benefit
Other Enrollment Periods
Medicare Cost plans
You can join a Medicare Cost plan whenever it’s accepting new members.
If you're newly eligible for Medicare and enrolled in Medicare Part B, you can enroll in a Cost plan anytime during your seven-month IEP.
Medicare Supplement (Medigap) plans
The best time to enroll in a Medigap plan is during the six-month Medigap Open Enrollment Period, which begins the month you are both age 65 and enrolled in Part B. If you apply for coverage outside of your Open Enrollment Period, you may have to provide your health history and be medically underwritten. You could also be denied coverage or charged a higher rate.
How to Enroll in Medicare
Medicare doesn't cover all your health care costs. Many people choose to enroll in a private Medicare plan to cover costs Medicare alone doesn't cover.
