Do I have to apply for Medicare if I am still working past 65?

Question

Angie Templin · Accepted Answer

If you are happy with your creditable employer plan, or if you are carry dependants on that plan, you can delay Medicare without penalties. You will get a special election to enroll in Medicare when you retire or when your dependants are eligible for other coverage. You can enroll in Medicare Part A only this time since it is generally free of premium. If you contribute to an HSA, delay Part A for now -IRS rules do not allow HSA contributions once you have a Medicare number!

Depends on whether your company has more than 20 employees; if so, then no, you do not have to enroll. If fewer than 20 employees, then yes, you must enroll in Medicare Part A &B

Christopher Boyd · Answer

Check with your employer HR department to see if they will cover you and, if applicable, your partner or spouse when you/they turn 65. If so, you will not need Medicare until you lose credible health/drug coverage.

Voss Speros · Answer

Voss Speros, Greek god of Medicare, here talking about Medicare. I got a cool new pink hat my wife got for me, probably for her more than for me, but I thought it’d be pretty cool to put it on.

The question is, do I have to sign up for Medicare if I'm still working past 65? No, you don't have to if you're working and you have credible coverage through your work. You don't have to sign up for Medicare at 65 if you're on an HSA plan and a Health Savings Account. If you want to keep contributing, don't sign up for Medicare if you're not on an HSA.

You can really just go on Part A and get that out of the way. So when you do retire, when you stop, and you want to go on Medicare, Part B is the only one you need to go on. When you stop working, you got a two-month window and a six-month window, depending on it, to go on Part B. You have a two-month window to go on Part B, and then you have a six-month window to pick a plan.

So you don't have to do it, but look into your options. Give us a call if you have questions. We'll help you out.

George Ibanez · Answer

If you are working and your employer provides creditable coverage you do not need to apply for Medicare part B, however, if you don't have creditable carrier from your employer and you do not apply for Medicare B then you will be paying an extra fee for your Medicare when you need your part B coverage and the penalty never goes away.

Mark Maliwauki · Answer

When you turn 65, Medicare will sign you up for Part A automatically. Part B will be signed up for as you leave your group health coverage from your employer. Make sure you give yourself at least a month prior to enroll in Part B. You have 63 days from the time you lose your employer coverage too sign up for a Medicare plan. There are a couple of different directions you can go.

Bill Wheeler · Answer

At 65  you are automatically eligible for part A if you have worked ten years or forty quarters. I would go on and get that. 
On part B if you work for a large company (more than 20 employees)  you can put off part B to a later date since you pay $185.00
A month for it. ob, you can delay enrolling in Part B without penalty until you retire or your employer coverage ends. You'll then have a Special Enrollment Period (SEP) to sign up for Part B without penalty.

Tony Capraro III · Answer

Do I have to apply for Medicare if I'm still working past 65? I hear that question every day at my State Farm agency here on Kelly Street in Manchester, New Hampshire. Here's the rules. As long as your employer has 20 or more employees, they do not have to be on the health plan, but if they have more than 20 employees, you can stay on an employer's health plan. However, you should deal with someone like myself who can show you exactly what Medicare would be. I've had situations over the last couple of weeks where it makes much better financial sense to go on Medicare than it does to stay on the employer's company plan. So please let me help you with that. We'll give you some great information so that you can make good decisions. Thank you.

Ray McCauley · Answer

no. Not as long as you have credible coverage with your employer you will not receive a penalty if you sign up for medicare within 60 days of leaving employer coverage.

Shelly Hefley · Answer

The important part is that you have credible prescription drug coverage. There are penalties involved in situations if you do not sign up for Medicare and do not have adequate coverage. There are certain rules with Medicare and Medicaid coverage as well as Medicaid and employer group plans. It’s always smart to talk to a licensed agent who deals with this all the time. It should save you time and a lot of hassles.

Nikki Rowland · Answer

You don’t have to apply for Medicare at 65 if you're still working—but it depends on your situation. 

Your employer coverage needs to be considered "credible coverage". That typically means they have 20 or more employees and the coverage is as good or better than Medicare. You can ask the HR department of your job and they would be able to tell you this answer.

If your coverage is NOT considered "credible" then yes, you would need to apply for Medicare. Some employers coverage may require you to take your Part B along with theirs. 

There are so many different situations.

Edward Wooten · Answer

If you’re working past 65, depending on your company size and work history, you might not need to apply right away. Still, signing up for Part A can give you extra protection when paired with active job or union coverage. If you’re getting Social Security or railroad retirement benefits, you’ll be enrolled automatically! You can delay enrollment if you keep working, but you’ll need proof of credible health coverage when you sign up for Part B. Once you do enroll in Part B, your monthly rate will be based on your income from two years earlier.

Sandra Bailey · Answer

No, you do not have to apply for Medicare if you're 65 and still working. As long as you work for a company that offers credible medical insurance.  Credible insurance, meaning you work for a company with 20 or more employees. You can remain on your group plan.

Once you leave the company, you'll obtain a letter from HR stating you had coverage and when it ended.  Then you can enroll in Medicare Part B.  

You can enroll in Medicare Part A (hospital insurance) even if you're still working.  This can be additional hospital coverage to go along with your work plan.

Ron Kaemmerer · Answer

As long as you have credible insurance coverage, no. Part A will come to you but Part B you will have to apply for later. You will need to complete a form from your employer showing what credible coverage was to avoid paying a penalty for not signing up sooner.

Make sure your credible coverage includes coverage for prescription drugs to avoid paying a late enrollment penalty for your drug plan.

Medicare Melanie · Answer

When deciding whether or not to apply for Medicare if you still plan to work after 65, it is more important than ever to sit down with your trusted broker to discuss options. Many people decide to enroll in Part A because there is typically no monthly premium, however factors such as contributing to an HSA could influence your decision on whether or not to do that. Another top consideration is that you lose your trial right when you do not apply for Part A at 65. 

Read more about trial rights below

Trial Right 1:
.
When you enroll in a Medicare Advantage plan for the first time when you turn 65, you have 12 months to switch back to Original Medicare with a Medigap policy.

If you switch from a Medigap policy to a Medicare Advantage plan, and then later decide you want to go back to Original Medicare, you have 12 months to do so.

It depends. If your employer has more than 20 employees and they are offering group help coverage, you don't need to apply for Medicare part A and B. Some people do however apply for Medicare part A because it's free and then you have extra coverage. If you have an employer that has less than 20 employees, then you would need to apply for both Medicare part A and B. The reason is that you need part D creditable coverage and group Health offers that.

Steven Bleicher · Answer

Yes. One of the biggest fallacies in medicine is that one must retire in order to be eligible for Medicare. This is the farthest from the truth! You are entitled to work for as long as you want. But just before you turn 65, you should compare the health benefits of your employer plan vs. Medicare. Unless you’re working for a large corporation, it is likely that the Medicare system is a better fit (both from a health perspective as well as from a monetary standpoint) than from the employer program. You can still work in your current job and simply tell your firm that they no longer need to pay for your health insurance. This means that they are off the hook (saving them money) AND since they don’t have to pay your healthcare policy, you will see a raise in your subsequent paychecks!

Frank Carta · Answer

You should receive a card from Medicare for Part A which is the hospitalization part of
Medicare that we pay for through Medicare deductions from our paychecks. 

Part A does not require you to pay premiums if you have more than 10 years of work credits.

Part B, for the doctors, costs a monthly premium that increases annually. You do not have
to file for Part B unless you do not have creditable coverage from your employer, in which
case you will also be required to have Part D prescription drug coverage.

So, working or not, you must have medical insurance whether it is Medicare or private creditable
insurance coverage.

Rich Baker · Answer

No, as long as you have CREDITABLE COVERAGE (insurance that provides coverage at least as good as Medicare’s) you do not have to apply for Medicare. MOST employer plans are going to be creditable, but you’ll want to check with your benefits administrator as you can pay a hefty late enrollment penalty if medicare later determines your coverage wasn’t creditable. 

Then, when you’re ready to retire and need to sign up, you’ll want to reach out to social security as soon as you know the retirement date to ensure you know what to do next. Generally you’ll need your employer’s plan information to prove you had creditable coverage. Once you have your A and B start dates, and you’re within 90 days of that date, you can sign up for your additional coverage.

At a minimum you’ll need Part D coverage, but I really recommend Medicap or Medicare Advantage to protect yourself financially. A good agent can help you determine which path is right for you.

James Stang · Answer

No, as long as you have credible coverage after you are eligible for Medicare you do not have to enroll. But you may want to enroll in Part A anyway. In most cases it does not have a premium, you have already paid for it by working 40 quarters and paying payroll tax, and it could help reduce your costs if you have a inpatient hospital stay. 

You can apply for Part B when you are ready to drop your Employer Group Health Plan.

Marnie Applegate · Answer

You will automatically get Part A if you or your spouse worked 40 or more quarters over your lifetime, but if you have group medical and prescription drug coverage that is as good or better than what medicare offers, then you can stay on your employer group plan until you retire or quit and then you will have an enrollment period to opt in for Part B and sign up for a supplement and prescription plan or a medicare advantage prescription drug plan. When you are ready to do that contact an insurance agent that specializes in Medicare 3 mos before you plan to retire and they can help you with the process.

Anna Davis CIC-RSSA · Answer

You should apply for Part A anyway—especially if you’ve worked and paid Medicare taxes for at least 10 years (40 quarters), as it’s usually premium-free.
Turning 65 is considered a qualifying life event, which means you have the right to leave your employer health plan if you choose to.
So what should you do?
Speak with a licensed Medicare agent in your area.
Compare the Medicare plans available in your ZIP code. Compare those plans to your current employer coverage.
Look at:
Monthly premium costs -  Doctor network access - Out-of-pocket costs (deductibles, copays, and max limits)
If Medicare offers better value—and in many cases it does—you can add Part B to your application and drop your employer coverage.
If not, you can keep your employer plan and Part A only until you retire. Later on, you can always enroll in Part B with no penalty, as long as you had creditable coverage.

Jason Vallejos · Answer

Not necessarily but do check with your Human Resources Department to make sure your current coverage is Medicare credible coverage to avoid penalties.

Heidi Delaney · Answer

As long as your employer group plan is creditable under Medicare, you do not need to apply for Medicare.  Employers are required to provide this information in September/October each year.  That said, you may be surprised to find that Medicare is more cost-effective for you.  It's good to compare costs and options side by side each year.

If, however, your employer group plan is not creditable, you will need to enroll in Medicare Parts A, B, and D to avoid late enrollment penalties.

Joseph Ford · Answer

Carlos Rodriguez · Answer

If your employer has 20 or more employees, you can usually delay Medicare without penalty as long as you have "creditable" coverage through your job.

However, if your employer has fewer than 20 employees, you generally must sign up for Medicare at 65, as it becomes your primary insurance.

If you have a Health Savings Account, you must delay Medicare to keep contributing.

Andrew Kramer · Answer

That depends. If you have an ACA plan (Affordable Care Act), then you must sign up for Medicare at age 65. But if you are on employer health insurance, the rule from Medicare is that you can keep your group health insurance, and not be penalized later for not taking Part B, if 20 or more employees are on the group plan. Not just employed, but on the group health plan. Second rule, does the drug plan of your group health meet Medicare's minimum requirements of Part D? If not, you will need to sign up for a Medicare Part D plan. Lastly, it's important to compare the cost of your group health plan, including the premium, deductible, co-pays and max out-of-pocket, to paying for Medicare Part B and either choosing an Advantage plan, or a supplement.

Barbara Barnes, CMIP® · Answer

Probably yes, but there are a lot of details that go into this decision that you need to consider. 

If you work for a small employer with less than 20 employees, Medicare will become your Primary coverage once you’re eligible and your plan at work will only pay what Medicare does not cover - usually deductibles and the 20% coinsurance. Some employer plans will only pay the secondary portion even if you never signed-up for Medicare, and that would potentially leave you responsible for 80% of the bill on your own if you have not signed-up for Medicare Parts A & B.

If you have an HSA that you or your employer puts money into, you must stop adding money to that account once you’re eligible and have Medicare - even if you only have Medicare Part A. For this reason, you might choose to delay enrollment into Medicare.

If you are paying a part of the premium for your health plan at work or if you have a high deductible, you may want to take Medicare instead of your coverage at work. It may cost less and/or cover more.

There are so many different scenarios that require careful consideration when you work past age 65 and become eligible for Medicare. You should speak with an expert before making decisions to be sure you’re doing everything correctly for the outcomes you want and to avoid penalties later.

Antonio Rodriguez · Answer

Not always. If you’re still working past 65 and you have good employer health coverage, you usually don’t have to sign up for Medicare right away. Most people delay Part B so they don’t have to pay the monthly premium yet.

However, if your employer has fewer than 20 employees, Medicare becomes your primary insurance and you should enroll at 65 to avoid gaps or penalties.

Everyone should still check whether they need Part A, which is often premium-free and can be beneficial.

If you’re unsure about your situation, I’m always happy to take a quick look and point you in the right direction.

Julie Thompson · Answer

If your employer offers you group health insurance, then no you do not have to. You will have an opportunity to do so when you leave that employer. This would be considered a special enrollment period (SEP). Be sure to ask if the prescription drug portion (known as Part D) of your employer plan is considered Creditable Coverage. You should receive a notice stating this every year. Should it loose creditability this would be an SEP and an opportunity to enroll in another plan.

Gary Haft · Answer

Normally you are automatically on Medicare Part A (Hospital Insurance) as of the first day of the month of your 65th birthday, even though you have not applied for it. Do you have to apply for Medicare Part B? No - not while you are still working, whether you are on your employers group health plan or an individual health plan. If your group has 20 or less employees on the group plan, then Medicare is Primary and you may be required to enroll in Medicare in order to have coverage. If the group is larger than 20 employees (21 or more) then Medicare is secondary to your group plan and your plan pays first and Medicare pays second. I don't recommend that anyone enroll in Medicare if they are still working unless they are required to. Besides, if you are on the group plan and NOT enrolled in Medicare, you do not have to pay the Medicare Part B fee.

Toni Chavez · Answer

Thanks for your question!  

If you’ve worked at least 10 years (that’s 40 quarters), Part A usually kicks in automatically the month you turn 65.

You can hold off on Part B if you’re still working and have credible coverage through your employer — but keep in mind, employer coverage is often more expensive than Medicare. I always do a comparison for my clients to see what actually makes the most sense financially.

If you don’t have employer coverage or any other creditable coverage, it’s important to enroll in Medicare at 65 — otherwise, you could face lifetime penalties.

When you’re ready to retire, I always recommend working with a broker (like me!) to help you apply for Part B. There are forms that need to be filled out and sent to Social Security, and I help walk my clients through that step-by-step — no cost to you.

Once you’ve got Part B in place, I can help you compare all the Medicare plan options in your area and get you enrolled in a plan that fits your needs and budget.

Working with a broker gives you peace of mind — not just when you first enroll in Medicare, but every year after that.

Hope this helps.  

Be Well,

Make sure your credible coverage includes coverage for prescription drugs to avoid paying a late enrollment penalty for your drug plan.

Mark Murphy · Answer

To answer your question, yes and no.  If you work for a company with more than 20 employees and your prescription coverage meets Medicare's minimum requirement, you do not have to register for Medicare.  In this situation your group plan would pay before Medicare paid.
If you work for a company with under 20 employees you must enroll in Medicare Parts A&B.  In this situation Medicare is the primary payer and the group plan would be 2nd.
It is always wise to speak with an agent 3 months before you turn 65 to look at your options and the costs of making such a move.  Sometimes it's best to move to Medicare, other times it's better to stay on the group plan until you retire.

Silvana Peacock · Answer

It depends. If you are still working past 65 and have creditable employer coverage (20+ employees), you usually can delay Medicare Part B without penalty. However many people still choose to enroll in Part A at 65, since is premium-free for most and can serve as secondary hospital coverage.

The answer hinges on your situation. Suppose you’re still working and covered by an employer health plan with 20 or more employees. In that case, you can delay Medicare Part B (and Part D, if your plan includes creditable drug coverage) without penalty until you retire. However, you should enroll in Part A at 65—it’s usually premium-free and may supplement your employer plan. If your employer has fewer than 20 employees, Medicare becomes primary, so you must enroll in Parts A and B at 65 to avoid gaps or penalties (8.33%–10% premium hikes for late Part B enrollment).

While Medicare Part A is automatic for most people turning 65 who have enough work credits, enrollment in Part B is not automatic. If you do not have other creditable health coverage, you must actively apply for Part B to avoid late enrollment penalties.

If you will continue to have employer coverage or another form of insurance when you turn 65, confirm that it is considered "creditable coverage" by Medicare standards. Having creditable coverage allows you to delay enrolling in Part B without incurring a late enrollment penalty once your other coverage ends.

Generally, if you're still working past 65 and covered by your employer's plan, you can delay enrolling in Medicare Parts A and B until you lose that coverage.

When considering Medicare enrollment, the size of your employer is a key factor to evaluate.

Are you working for a large employer or a small employer? Let’s break it down:

If you’re turning 65 and covered by a large employer’s health plan (with 20 or more employees), your group health plan will remain your primary coverage, while Medicare takes a secondary role. In this scenario, enrolling in Medicare Part A or Part B may not be necessary. 

However, many people choose to enroll in Part A since it typically doesn’t have a monthly premium if you’re eligible. I recommend holding off on Part B, as it does come with a monthly premium. There’s no need to pay for both your group plan and Part B when your group plan is already taking care of your primary coverage. Instead, you can enroll in Part B later, such as when you retire or leave your group plan, without incurring a penalty because your group coverage qualifies as creditable employment-based insurance.

Now, let’s look at the situation if your employer has fewer than 20 employees. In this case, Medicare becomes your primary insurance, and your group health plan shifts to secondary coverage. This means you’ll need to enroll in both Part A and Part B to maintain full coverage. 

Understanding how Medicare coordinates with your employer’s health plan is essential for making the right choice and avoiding unnecessary expenses.
