Why do some seniors end up paying lifelong penalties for Medicare Part B or Part D?

Question

Samantha Jellison · Accepted Answer

Lack of appropriate retirement planning education. One of the foundations I have built my business on is education. Medicare 101 seminars can be really useful to people to learn how to avoid these penalties. 

It is important to know that unless you have what is known as Creditable Coverage, delaying Part B and or Part D can carry lifelong penalties. Each situation is unique so it’s important to consult with a professional to understand if you have Creditable Coverage or not and have a plan in place, months before you turn 65. Sorting out your Medicare coverage is best done up to 3 months before you turn 65.

Hi. Thanks for watching. My name is Steve. I'm the husband, half of the husband-wife medical team here in Arizona. Sue's off today. The question we're looking at is, why do some seniors end up paying lifelong penalties for Part B and/or Part D?

Now, remember, Part B is the medical insurance piece of Medicare, and Part D, D for drugs, is the prescription drug coverage. So here's what happens. Sometimes people get bad advice or they think they don't have to sign up. There's a million situations as to why people get penalties, but find an independent Medicare agent that only does Medicare, and they can help you through this.

But typically, when you turn 65, unless you have employer coverage that's deemed what they call credible, meaning it's as good a coverage as Medicare or better, if you have that, then you're fine to delay your enrollment until you leave your employer. If you have a small employer, or if you don't have any other coverage or whatever, if you don't have credible coverage, you have to sign up when you're 65.

So there's some moving parts to this. And that's why you should lean on your independent Medicare advisor to figure these things out and talk through it with you.

Norman Smith · Answer

Penalties are assessed when a Senior hasn't deferred or shown proven health coverage, including Prescription coverage, adequate in comparison to the Medicare offerings.
This why it is important for every person, before or at their 65th birthday to visit SSI.gov or Medicare.gov, to address what needs they will have moving forward. Almost everyone takes their no premium Part A, even as a secondary coverage. But unfortunately, people don't understand they need to defer the B and D to avoid penalties, if they are going to keep work coverage, military, or other continuous health coverage plans.

Lt Col Tim Brown · Answer

Mainly because people don’t know the rules. This is why you need a professional agent/broker. If someone does not have credible coverage and goes past their enrollment period, they have a penalty for life. Or If their income is considered high, they get ugly aunt I.R.M.A. (income related monthly adjustment) attached as a penalty until such time as their income drops. None of this is fair, just what they can do (the rules).

Seniors who end up paying lifelong penalties must do so because they neglected to enroll in Part B when they were originally eligible. There is a monetary penalty for each month they were eligible, but did not enroll in Part B unless they had creditable health coverage through employment.

Voss Speros · Answer

Voss Speros here, Greek god of Medicare. If Medicare's all Greek to you, you're in luck. I'm Greek. So the question is, why do people end up paying lifelong penalties for Part B and D of Medicare? You go on Medicare at 65 and you're like, "I don't need Part B. I just take A because it's free." I'm like, okay, yeah, that's fine. But if you have credible coverage through work, you don't need it. But if you just don't have any coverage at 65 and you just take A and that's it, or you take A and B and say, "I don't need drug coverage because I don't take any drugs." So later in life, when you do need Part B for some reason or Part D drug plan, there's a penalty. The government, you didn't pay the government for all those years for Parts B and D because you didn't want to. Well, they're going to get it back when you do need it in the long run. They're going to be like, "Oh, yeah, now you're stuck with a lifetime penalty for every 12-month period of Part B that you didn't do." It's 10% of the average monthly income for that monthly average premium. So $185 right now, 18 bucks for as many years as you didn't take it. Part D, they're going to be like, it's like 1% of the average cost of Part D on a monthly basis for as many months as you didn't take it. So roughly 33 cents right now a month for as many months as you didn't take it. So it's not a lot, but it adds up and then it's a lifetime penalty that stacks onto what you owe. Now you want it. Well, you're going to pay back to the government for not taking it when you were supposed to take it. So they're going to get their money back. So if you need it in the long run, there's where the penalties come in. Make sure to get on something at 65 or when you retire that covers what you need. Talk to a broker, find a plan. If you need help, give us a call. We'll send somebody out to help you out. Thank you.

Lynn C Shurtleff · Answer

If you delay signing up for Medicare Part B or D you will pay a penalty based on the length of time you delayed signing up. These penalties last a lifetime unless you qualify for help due to income. It is not recommended to delay signing up because depending on the period of time these penalties can become cost prohibitive over time.

Gregg Matheny · Answer

When they were originally eligible for Medicare part B or a part D plan they did not enroll and Medicare starts keeping track after 63 days or more In which you were uncovered. The kicker is that Medicare doesn’t assess that penalty until you get Medicare part B. Same goes with part D, If you didn’t get a prescription plan when you were first eligible for one and 63 days or more has passed then Medicare will keep track of the number of months that you didn’t have a prescription drug plan and a penalty that roughly ends up being about $.35 per month (in AZ) gets multiplied by the number of months that you didn’t have prescription drug coverage. That amount gets added to what your part D premium is.

Medicare allows a few scenarios where you can wait to sign up for Part B or Part D. For example, if you or a spouse is working and has coverage available from an employer, you may be able to stay on the plan and wait to enroll in Part B, and/or Part D. However, if you do not have "credible" (coverage as good as or better than Medicare) coverage and you do not sign up for Medicare Part B or Part D when you first become eligible, you will pay penalty amounts once you do sign up.

Brian Moore · Answer

Some seniors face lifelong penalties for Medicare Part B or Part D because they miss their initial enrollment period—typically the seven months surrounding their 65th birthday—and lack qualifying coverage, such as an employer plan, to justify delaying enrollment. For every year they’re late, Part B adds a 10% premium penalty, while Part D increases by roughly 1% per month missed, and these extra costs stay with you permanently since Medicare enforces timely sign-ups to maintain its structure. I’ve seen this catch people by surprise, especially when they overestimate their existing coverage, making it a costly oversight to avoid.

Part D rx coverage is similar but needs to be placed within 63 days of becoming eligible for Medicare

Mark Cook · Answer

Because Medicare Part B and Medicare part D are both ruled by the same insurance philosophy. The rule of large numbers. Everyone needs to participate in order for it to make sense. So the federal government has come up with a set of guidelines that include penalties that are reasonable and equitable that would penalize individuals that when they do qualify for part B and part D, for whatever reason, decide NOT to participate. When these individuals decide not to participate in our communal system that is in place to provide insurance to what should be some of our most protected groups of Americans due to their vulnerability…and that’s our seniors and the subgroup of individuals that are on disability; penalties are a wise deterrent in helping reduce this outcome

Misty Tucker · Answer

Late Enrollment penalties (LEP's) are a result of not having creditable coverage through an employer or spouse and not being enrolled in Medicare Part B or Part D after age 65. Part B and Part D (drug) penalties are calculated based on how my many months you went without being enrolled in Medicare Part B and Part D past age 65. Medicare Part B penalties may go away after a certain amount of time, Part D penalties never go away. LEP's are avoidable by enrolling in Medicare Part B and Part D at age 65 if you do not have "creditable" coverage. Medicare considers most group employer plans creditable, but it a good idea to check with your HR dept ahead of your 65th birthday to verify.

Steven Bleicher · Answer

It’s mostly for folks who when they joined Medicare took no prescriptions and were riled up about picking up a Part D(rug) plan. So, they refused to pay for the sometimes free PDP or Prescription Drug Plan. Medicare believes that every senior should have drug coverage since they knew that eventually most everyone’s health deteriorates as they age. There is a lifetime penalty for every month after age 65 that you don’t have a PDP. The actual penalty is not bad but if years go by, that amount when added to your plan’s premium can be a bit off-putting.

When you first age into 65 a lot of seniors do not know about the penalties for not taking a Drug plan or Part B. This is not good considering they do not know about these things unless an agent tells them. The Part B penalty is because they did not take Part B when they were first eligible for medicare and it is the same with Part D. Always connecting with an agent when you age in is the best thing.

Steven A James, MBA · Answer

Social Security expects a new Medicare beneficiary to enroll in their Part B as well as a Part D prescription drug plan (PDP).

When turning 65, you'll have a 7-month window (3mo ahead before your birth month, your birth month, and 3 months thereafter) to enroll in your Medicare Part B.  If not, a Late Enrollment Penalty (LEP) would apply.  If one goes longer term without having enrolled in their Part B, they'll eventually pay an additional 10% for each year without coverage above the current standard rate at the time of issue.

If one is retiring and losing employer/group coverage, they'll have the opportunity to enroll in their Part B without penalty, so long as creditable coverage has been verified.

Social Security also "expects" one to have a qualified PDP.  If one doesn't enroll in a PDP plan, nothing happens until there is enrollment into a plan; either a standalone PDP or a Medicare Advantage Plan w/PDP.  The LEP here is a % of the current standard rate for a PDP at the time of issue, multiplied by a % factor to establish the LEP.

Unfortunately, in either circumstance where an LEP is applied, this penalty is for life.  Thus, it's always wise to make sure there's adequate research before becoming Medicare eligible or simply contact a credible agent.

If they miss an enrollment window and do not have qualifying creditable coverage as good as Medicare then they will have a penalty imposed upon them. For example, if an individual has started Original Medicare (A&B) but they decline Part D (prescription drug) and they have no other insurance then they will begin to accrue a penalty until they pick up a Part D drug plan. This penalty continues to accrue every month they go without coverage. Once they do pick up Part D then a penalty will be assessed for every month they went without and they will continue paying said penalty for their lifetime.

Seniors end up with lifelong penalties for Part B or Part D when they go without creditable coverage and don’t realize they were supposed to enroll. Medicare charges these penalties to discourage people from waiting until they get sick to sign up — but most penalties happen simply because no one explained the rules to them.

Here’s why it happens so often:
They didn’t know their employer coverage wasn’t “creditable.”  
They missed their Initial Enrollment Period at 65.  
They thought “I’m healthy, I don’t need it yet.”  
They relied on misinformation.  

These penalties are permanent they last for as long as the person has Medicare.  
That’s why I believe in Medicare guidance and educating on Medicare basics, it really matters so much. I help people avoid mistakes they didn’t even know were possible.

Delaying Part B Medicare and Part D prescription drug costs will incur a penalty when you do apply for it at a future date. The penalties will be in place for the rest of your life once incurred. Having credible medical and prescription coverage from an employer group insurance plan can eliminate the potential penalty.

Seniors pay lifelong Medicare Part B and D penalties, often exceeding 30% of their premium, due to missing enrollment deadlines, lacking "creditable" coverage, or misunderstanding rules while working past 65. Penalties are added for not signing up during the initial 7-month window and remain for life.

Cori Richerson · Answer

You can have a penalty for Part B or Part D if you do not enroll when you are first eligible. There are timeframes that are specific for each part that determine penalty amount. If you are still working and have credible group coverage through your employer then the penalty is waived if necessary documentation is received. 

Part B - you incur a 10% penalty for every 12 month period you were eligible but did not enroll.  This penalty you pay monthly for the rest of your life. For example you didn't have Part B for 3 years, you enroll now. You pay a base premium of $202.90 in 2026 + 30% ($60.87) for a total premium in 2026 of $263.77 per month. 

Part D - you incur a 1% penalty for every month you did not have coverage and were eligible. The 1% is of the average prescription drug plan premium for that year.

Rachel Armstrong · Answer

Unfortunately, if a beneficiary does not enroll as soon as they are eligible for Part B and Part D a penalty will be accrued. The Part B late enrollment penalty is 10% of the standard premium for each year that a person delays enrollment after their initial enrollment period. The Part D penalty is 1% of the national base premium for each full month the go without coverage that you were eligible and didn't enroll. This penalty is often time added to your Part D monthly premium. Both penalties last as long as you are enrolled in Part B or Part D.

Toyin Adeleye · Answer

A lot of the time people decide that the coverage they have for their healthcare needs is all they need. Sometimes these other insurance coverages- like COBRA and some retiree health plans- do not count for Medicare as creditable coverage (what the government considers equal to or better than what medicare has to offer). 

Say the person's health suddenly gets worse- which is more likely the older we get- and they decide they now want to get onto Medicare; well this person is now considered a higher risk health-wise, and will likely "cost more" for the system to insure. Medicare will penalize them for as long as they have Medicare to essentially ease the costs on the greater system and deter others from not applying on time. This person can choose to never get onto Medicare; but if they do decide to get on, they will pay more. 

It sucks to find out about these penalties after the fact, which is why I always encourage people to look into Medicare well before they turn 65, and make a plan. If it's too late, one can look into appealing this penalty.

I hope this helps!

Fred Manas · Answer

Seniors can incur lifelong penalties for Medicare Part B and Part D due to late enrollment or missing enrollment periods. These penalties are designed to encourage prompt enrollment and discourage waiting until health needs arise. For Part B, the penalty is 10% of the premium for each 12-month period of delayed enrollment. For Part D, the penalty is 1% per month of delayed enrollment. 
Here's a more detailed breakdown:
Why the penalties exist:
Risk Pool:
Medicare's cost-sharing mechanism relies on a balanced risk pool, where healthy people contribute to cover the costs of those who need more care. If everyone waited to enroll until they needed coverage, costs would skyrocket. 
Prompt Enrollment:
The penalties incentivize people to enroll in Part B and D when they become eligible to avoid potential financial hardship later on. 
How to avoid penalties:
Initial Enrollment Period (IEP):
Enroll during your IEP, which is the seven-month period around your 65th birthday. 
Special Enrollment Periods (SEPs):
If you have creditable coverage through an employer or other qualifying coverage, you may be eligible for an SEP, which allows you to enroll without penalty within a certain timeframe after losing that coverage. 
Avoid Creditable Coverage Gaps:
Ensure you have continuous coverage or are enrolled in Medicare when you become eligible to avoid penalties. 
In essence, late enrollment penalties are meant to encourage timely enrollment in Medicare Part B and D, promoting a more balanced and sustainable healthcare system.

Gary Henderson · Answer

Medicare signs a penalty if you do not sign up during your initial enrollment period, which occurs at age 65 or if after 65 after you've left a qualified plan, for example from your employer. If you fail to enroll then you are assigned a 10% penalty per year for part b, which means 10% of the current part b payment which this year is $185. So that would be $18.50 per year, and the drug plan is 1% per month of the average cost of a drug plan which is about $0.40 a month. A 
Month these are permanent lifetime penalties and added to your cost of your insurance. Therefore, know the rules. If you don't know, contact qualified insurance agent like me

Linda Davies · Answer

Seniors may miss their IEP, which is a seven-month period around age 65, or miss a Special Enrollment Period if they continue working past 65. 

Some seniors believe they have adequate coverage through a current employer, retiree plan, or other insurance and delay enrolling in Part B, only to find it doesn't qualify as creditable coverage. 

Some individuals are simply unaware of the importance of enrolling in Part B when eligible, or don't understand the rules surrounding enrollment deadlines. 

If they don't enroll during their Initial Enrollment Period (IEP) or Special Enrollment Period (SEP) and don't have creditable coverage from another source. These penalties are a 10% increase to the Part B premium for each 12-month period they delayed enrollment. The penalty is designed to encourage timely enrollment and maintain a balanced risk pool for Medicare. 

Some seniors pay penalties on Medicare Part D, primarily because they either missed their initial enrollment period or didn't maintain continuous coverage through creditable prescription drug coverage. This penalty is a monthly add-on to their Part D premium, calculated as 1% of the national base beneficiary premium for each month they lacked coverage. 

The penalty aims to encourage individuals to enroll in Part D when they become eligible to ensure they have consistent coverage for prescription drugs.  Without a penalty, some individuals might delay enrolling in Part D until they need costly medications, shifting costs to those who enroll promptly.

The penalty also discourages people from dropping Part D coverage and then re-enrolling later when they need expensive drugs, potentially straining the program.

For Part B, if you don't sign up when you're first eligible and don't have creditable coverage through an employer, you get hit with a 10% penalty for every 12 month period you could have had it but didn't. That penalty sticks with you permanently, added to your premium every month for as long as you have Part B. Part D works similarly but calculates it differently, roughly 1% of the national base premium for each month you went without creditable drug coverage. These penalties exist to discourage people from waiting until they get sick to sign up, but a lot of folks get caught simply because they didn't understand the rules or thought they could delay without consequences.

The most likely reason. For part B is they waited over a year after receiving part A and did not have credible medical insurance coverage.
As first part D usually the same reason As mentioned already however they went over 63 days with no prescription drug coverage.!

Rene Apack · Answer

People who ignore to enroll.when they turn 65 within 6 mongh for their Oart B premiums and or within 3 months fail to enroll to Medicare Prescription Drug Plan will pay penalties for the rest of their lives.
Simple solution sign up for your Medicare Part B before you are turning 65 on live at SSA.gov and get a Medicare broker who works with all the companies and you get either your Medicare Supplement Plan and your Prescription Drug Plan  OR your Medicare Advantage Plan.
Done.
I hope this helps you

Some seniors pay lifelong penalties for Medicare Part B or Part D because they didn’t enroll during their initial eligibility period and didn’t have other credible coverage. These penalties are added to their monthly premiums and continue for as long as they have the coverage.

Velvet Ohlen · Answer

Great question. Seniors who do not enroll in Medicare Part B or have creditable coverage will have a penalty. 
Seniors who do not enroll in a stand alone or Medicare Advantage plan that offers Part D coverage will have a 1% penalty. 

Please see below: 

The penalty for late enrollment in Medicare Part B is generally an extra 10% of the monthly premium for each full 12-month period you could have signed up but didn't. For Part D, the penalty is 1% of the national base beneficiary premium for each month you didn't have coverage, and this is added to your monthly Part D premium. Both penalties are often permanent once incurred.

Calvin Fritz · Answer

Some seniors end up paying lifelong penalties for Medicare Part B or Part D because they didn’t enroll when they were first eligible and didn’t have other qualifying coverage during that time. Medicare imposes these penalties to encourage timely enrollment and to keep costs down overall.

Part B:
If you don’t enroll in Part B (medical insurance) when you're first eligible and don’t have other creditable coverage (like employer insurance), you may face a permanent penalty.

Part D:
If you go without creditable prescription drug coverage (like from an employer or union plan) for 63 days or more after your Initial Enrollment Period, you’ll pay a penalty when you do enroll in Part D.

How to Avoid the Penalties:

Enroll on time: During your Initial Enrollment Period (IEP)—a 7-month window around your 65th birthday.

If you have employer coverage, enroll during a Special Enrollment Period (SEP) when that coverage ends.

Always maintain creditable coverage to avoid gaps.

Jonathan Brower · Answer

If you are eligible for part B or D and do not have other credible coverage in place you will begin being penalized.  The penalties are permanent and will never go away.

Mindy Kay · Answer

Some seniors pay lifelong Medicare penalties because Medicare requires you to enroll when first eligible unless you have other creditable coverage (such as employer insurance). Delaying without qualifying coverage signals higher future risk to the system — so penalties are added to your premium.

🔹 Part B Penalty:
If you don’t sign up when first eligible, your premium typically increases 10% for every 12-month period you were eligible but not enrolled. In most cases, this higher premium lasts for life.

🔹 Part D Penalty:
Going 63 consecutive days or more without creditable prescription drug coverage triggers a penalty calculated monthly and added to your Part D premium — also generally permanent.

Common Reasons People Get Penalized:

Assuming they could enroll anytime

Not realizing COBRA or some retiree plans may not count as creditable

Missing enrollment deadlines

Believing they don’t need drug coverage because they take no medications

Kelly Anderson · Answer

Seniors often face lifelong penalties due to missing their initial enrollment window when turning 65. Penalties occur due to not understanding the complex Medicare guidelines.

Michael Reardon · Answer

1. Part B Late Enrollment Penalty 
It is a penalty that encourages people to sign up when they are first eligible. When you do not sign up for part B and you are first eligible and you do not have credible coverage you will receive a 10% of the standard part B premium for each 12 month. You could have part B but didn’t. The penalty is added to your premium for as long as you have part B.

 2. Part D Late Enrollment Penalty

When it happens:
You go 63 days or longer without “creditable” prescription drug coverage after you’re first eligible for Medicare.

Penalty amount:
	•	1% of the “national base beneficiary premium” for each month you were without coverage.
	•	That amount is added to your monthly premium for as long as you have Part D — again, typically for life.

Jon Harkness · Answer

Lifelong penalties are a result of not signing up for Part B or Part D, and then later on having to sign up for one or both due to medical conditions.

Medicare gives you the option to not sign up for it, and for the moment it seems like a great way to save money - especially if you are fairly healthy (minimal doctor's visits and prescription drugs) - but in the long wrong it is far more detrimental to your bank account if, one day, you require major medical assistance or go on a brand-name drug.

The penalties are a set-percentage added on to your monthly premium (1%/month or 12%/year) and roll over every month/year. So, if you've not had Part B/D for 10 years you could have a 100-120% interest rate added on to your monthly premium that you'll be required to pay in order to receive coverage.

Best to sign up for your Part B and D when you turn 65 and/or retire to save major money in the long run.

Debra Weber · Answer

If you do not pick up your part b when first eligible for Medicare you will be charged a penalty whether under 65 or at 65. If you are under 64 and do not pick up part b then, when you turn 65 and pick it up  the penalty goes away.
For part d, if you do not pick up a plan when eligible then you have the penalty

Zachary Montgomery · Answer

Because Medicare is such a robust coverage model with guaranteed issue options regardless of health, it is a very expensive healthcare model. To mitigate this, individuals are required to enroll within certain periods to collect premiums before it becomes necessary for those beneficiaries to use their benefits. To further mitigate individuals that do not enroll within those time periods, fees or penalties are levied to offset their missed premiums. While Medicare is not mandated, many other forms of health insurance is illegal after Medicare eligibility. It is important to meet with your agent to understand when you should or should not enroll in Medicare and how to avoid penalties correctly.

Because they didn't enroll in a timely manner for Part B and Part D - they were given poor information from their Plan administrators OR they had NO idea they had to enroll.

Christopher DiBiase · Answer

Short answer: They don't consult with an experienced professional. Long answer: Medicare is different from health insurance, since it is government-sponsored, and there are more rules, regulations, and guidelines to follow. There are generous time frames to enrolling and many think they can get it if and when it is needed. Those errors are unforgiving; the government fines people for the remainder of their lives.

Mark Rich · Answer

The most common reason for Medicare beneficiaries enrolling late in Medicare Part B and/or Part D is carrying other health insurance (usually through an employer) past their 65th birth month.  Beneficiaries who enroll late, for this reason, can avoid the late enrollment penalties if they obtain proof of "creditable" coverage from their employer and furnish it to CMS.  Unfortunately, some fail to do this.  Others, out of ignorance, either fail to sign up for Medicare Part B when they should or cancel Part B because they do not want to pay the monthly premium ($185/month in 2025).  Similarly, some fail to enroll in a Part D Prescription Drug Plan, which can also expose them to a lifelong late enrollment penalty.  These are among the many reasons every Medicare beneficiary should engage an experienced local Medicare Health Insurance agent before turning 65.  An agent can help assess whether it is even wise or cost-effective to continue in non-Medicare health insurance coverage through an employer.  Oftentimes, changing to Medicare at age 65 and starting a Medicare Health Plan is more economical.
