Why does Medicare have so many coverage gaps, and is it designed that way on purpose?

Question

Brian Penner · Accepted Answer

Great question — and honestly, one I hear in my office more than almost any other. The frustrating answer: yes and no.

Medicare wasn't designed with "gaps" as a trap. It was designed in 1965 to mirror the private insurance of that era — hospital coverage (Part A) and doctor coverage (Part B), with cost-sharing so the program stayed solvent. What we call "gaps" today — deductibles, the 20% coinsurance with no cap, no dental/vision/hearing, limited long-term care — are mostly things that were never included in the original design, and Congress has patched them piecemeal ever since: Part D for drugs in 2006, the $2,100 out-of-pocket cap on prescriptions that took effect in 2025 under the Inflation Reduction Act (it's indexed annually).

The part that surprises people most: Original Medicare has no out-of-pocket maximum on Parts A and B. That 20% coinsurance can run forever on a serious illness. That single gap is why an entire industry of Medigap plans and Medicare Advantage exists — private coverage filling the spaces the public program left open.

So is it "on purpose"? The gaps exist because of when the program was written and the political compromises made since — not because anyone's trying to trick you. But the consequence is real: the coverage you end up with depends heavily on the choices you make at enrollment, and some of those choices (like Medigap enrollment windows) can close permanently.

Gary Burroughs · Answer

That’s a thoughtful question, and the short answer is: yes, Medicare’s gaps are largely by design.

When Medicare was created in 1965, it was never intended to cover everything. The structure was built to:

• Share costs between you and the program (deductibles, 20% coinsurance) to help control overall spending
• Focus on medical care, not things like dental, vision, or hearing, which were considered outside core coverage at the time
• Leave room for private insurance—that’s why Supplement (Medigap) and later Medicare Advantage plans exist to fill in those gaps

Over time, healthcare has evolved, but the basic framework hasn’t fully kept up—so those gaps are still there today.

Bottom line:
Medicare gives you a strong foundation, but it was intentionally designed to be paired with additional coverage if you want more complete protection.

Ann Sanfelippo · Answer

Originally, Medicare was designed to cover basic medical needs, not to function as full, first-dollar insurance. Cost-sharing like deductibles, coinsurance, and coverage limits were intentionally built in to help control overall program costs and reduce overuse. Over time, those gaps led to the creation of Medigap, Part D, and Medicare Advantage plans to fill in or manage those costs. So yes, the gaps are intentional, but Medicare also provides options to help beneficiaries manage them.

Linda Davies · Answer

While various parts of Medicare provide widespread health coverage, these do not always pay 100% of the cost of what it covers. For example, there may be deductibles for:

Part A hospital services
Part B doctor and outpatient services
Part D prescription drugs

After these deductibles are paid, there are often gaps in what Medicare will pay for your covered health care, such as:

Part A of Medicare has expensive copays for people with long stays in hospitals and skilled nursing facilities.

Part B of Medicare pays only 80% of covered expenses for the costs of doctors, durable medical equipment and other outpatient expenses.

Copays and drug costs charged by Part D drug plans can differ among Part D insurers, even for the same drug.

Marnie Applegate · Answer

I’m not sure if you’re looking for a specific answer for a coverage gap on Medicare supplement or Medicare advantage plan so I’ll try to be general and answering. Each type of plan has out-of-pocket expenses for services not covered deductibles and coinsurance. Original Medicare has 20% responsibility for the beneficiary. You can pick up a Medicare supplement also known as a Medigap plan to cover that 20% but you’ll still have depending on which letter plan you pick a deductible and excess charges. You’ll also have the cost of a prescription plan the cost of the drugs and any deductible. However, with the elimination of the donut hole or coverage gap, the max out-of-pocket spending for cover drugs is capped at $2000 in 2025 and it will increase to $2100 in 2026. If you have a Medicare advantage plan also known as part C there are specific coverages that vary between plans and those have different premiums, max out-of-pocket and co-pays and they are all developed based upon each carrier and the plans that they choose to offer. It is really important that you sit down with a knowledgeable agent that can explain the differences between original Medicare, Medicare supplement plans, prescription plans, and Medicare advantage plans and review not just the premium cost but what your overall cost could be as a result of coverage gaps. I hope that helps

Michael Martin · Answer

When Medicare was created in 1965, it was designed to offer basic health insurance for seniors, not to cover everything. 

Medicare’s structure creates space for private insurance companies to offer supplemental coverage (like Medigap or Medicare Advantage). This public-private hybrid model was intentional—it allows the government to provide a foundation, while the private market fills in the gaps.

Harold Randolph · Answer

Good Question. The overall cost of healthcare is a staggering number. The coverage gaps are there so that you provide some of the cost share. So the answer is yes. 

Part A has a period deductible while Part B has a small annual deductible and an 80/20 coinsurance with unlimited out of pocket maximum. 

It can become confusing with all the changes but reaching out and having a Broker can help make sure that feel less of the out of pocket with the right plans and options.

Kelly Corbin · Answer

The gaps arise from the structure of the program and its cost-sharing mechanisms. Medicare does cover a broad range of medical services, but it does not cover everything. Persons on Medicare are responsible for certain out-of-pocket expenses like deductibles, copayments, and coinsurance. These gaps are not intentionally designed to cause hardship. They occur due to policy choices and cost-sharing which anre intended to balance affordability and comprehensiveness.

Hi. Thanks for watching. My name is Steve and I'm the husband half of the husband and wife team, Arizona. So the question is, why does Medicare have so many coverage gaps? And is it designed that way on purpose? So they're never going to tell you this. But yes, it is a sign like that on purpose. And I really feel that they have these coverage gaps because they want people to have some skin in the game. If everything is free, I mean, it would basically be socialized medicine. Everything was free. When you went down, you got everything for free and you never had to pay anything. I mean, people would be going down for everything. I think, but depending on your coverage, you have to either pay a monthly premium for your supplement or Medigap plan and drug plan, or it's a zero premium Medicare Advantage plan. And it's copay based. Meaning when you go to get services, it's a cost share pay. Like I use my plan, I go to the doctor, I go to my primary. It's zero. If I go to the specialist, it's $8. Go to the hospital. It's a copay for the first five days. They want that skin in the game because they know if it was totally free, people would abuse it. Not everybody, but a lot of people would.

Denise Berg · Answer

Original Medicare was designed to provide Hospital Services and Doctor Services. However, with those gaps in coverage, Medicare Advantage and Medicare Supplement plans were offered help fill in some of the gaps. With most Medicare Advantage plans offering Dental, Vision and Hearing; and Medicare Supplements plans providing additional benefits for the Hospital and Doctor Services portions.

Larry Dalton · Answer

In 1965, the government set up Medicare to help primary care for those over 65 with healthcare costs. President Johnson set it up to share healthcare costs between the government and beneficiaries. This was called the cost-sharing approach, with the intent to help control Medicare abuse and overcharge by discouraging unnecessary use of the services.

Today, with healthcare costs rising, the original design has revealed six major gaps in its coverage. Therefore, yes, I think it was designed this way in the beginning, which makes it very confusing today. You need to make sure you have the right coverage and can’t afford the coverage of these gaps.

Justin Lester · Answer

Original Medicare was originally designed to cover major medical expenses, but unfortunately not every healthcare cost such as dental, vision, hearing, cosmetic surgeries, long term care etc.
That's why there is deductibles and coinsurance.. Many people fill those games with a Medicare Supplement plan, Part D plan, hospital indemnity, cancer plan, long term care plan and sometimes replace original medicare with a Medicare Advantage (Part C) plan.

Vachik Chakhbazian · Answer

The gaps are not intentionally designed to cause hardship but are the result of policy choices made to balance affordability and comprehensiveness, leading to out-of-pocket costs like deductibles and coinsurance. Beneficiaries often fill these gaps by purchasing supplemental insurance, such as Medigap policies or enrolling in Medicare Advantage plans.

Bruce Kaserman · Answer

Because it is designed to allow individuals to choose their own coverages based upon one's finances and one's specific needs. If you have the financial means, you can elect to take out a Medicare supplement and a specific Prescription Drug Plan. If you are just OK with Original Medicare (Parts A&B), then all you need to have is a separate PDP( Prescription Drug Plan) to meet the Medicare Requirement. Or if you want to take out a general Medicare plan for yourself, you can take out a Medicare (MA plan) that also includes PDP benefits. However those do have holes inside of them and an experienced Medicare Professional like myself, can help you fill out those holes with coverage that fits with those holes.

Medicare was designed decades ago and really has not changed much per original Medicare. It covers basics but not 100% and was not designed to cover 100%. That is why there are supplemental plans you can pick up to help cover some of those gaps and give you predictability for costs.

You are a bit behind the times. The problematic “Donut Hole” (Rx’s) has been eliminated by the Inflation Reduction Act of 2023/24. This was a gap where folks would reach a certain dollar cost for their drugs & their copays would go up. Now in 2025, the maximum out of pocket amount is $2,000.00, tops! This is for both generics & brand name drugs. That is a great help for those less fortunate.

Abigail Turner · Answer

That is a loaded question! Medicare, similar to any other health insurance, was never meant to cover everything, and certainly not at 100%. There is no health insurance that offers that kind of coverage, unfortunately! 

Many people argue Medicare should add coverages it currently doesn't include (such as dental/vision/hearing) but we also have to remember, Medicare is a government program so that just means we would have to pay in more money.

Deborah Webster · Answer

Original Medicare does have gaps; this is why it is important to purchase supplemental plans that can help fill those gaps. You can contact a ship office or a local agent to discuss what those plans consist of and what they cost. Whether it was designed well or not, it is the healthcare option that seniors must work with as of now.

Tony Capraro III · Answer

Why does Medicare have so many coverage gaps, and was it designed that way? No, it's a government program, so there's a lot of good in there and a lot of not-so-good. People have to come up with their own decisions. It's Medicare alphabet soup. How do I do the best for me and my family at age 65, knowing that at age 65, most times my health is not gonna get better? Work with someone like myself who can give you all your options, whether it's Medicare A and B only, Medicare A and B with a supplement, or Medicare Advantage, which you see all those 800 numbers and all the mailings you're probably getting. Work with someone like myself who can give you all the pros and cons of each program before you make that all-important Medicare decision. I'll be glad to help. We know it inside and out; we deal with clients every single day. Yes, it is confusing. Why? Because it's a government program. Work with someone who can help you out with that and make the right decisions. Great decisions come from good information.

Lilyana Uzdenova-Gomez · Answer

Medicare was not meant and can not  provide full coverage, as it is funded by payroll taxes and premiums. 
   It’s a baseline for the qualified consumer to add on to. Most consumers should be able to find a fitting plan between Medicare Supplement and the original Medicare, or the Medicare Advantage plans.

Juan Beraldi · Answer

The cost of healthcare in the USA is very high and the amount we pay for Medicare coverage cannot pay for all services. For Medicare to pay a higher amount to lower our out-of-pocket, they will have to increase the Medicare premium and amounts we pay on our taxes. 

Currently the Medicare premium is $185. They also pay 80% on the medical expenses (Part B) and have a Part A deductible (Hospital) of $1632 for hospital stay up to 60 days.

If you'll like more details about it's coverage and how to lower your out-of-pucket, you can call me and I can explain in more details

Andrew Kramer · Answer

Not sure what you're referring to as "coverage gaps?" Do you mean the 20% that Medicare does not pay? Or the Part B deductible, which this year is $257? If that's what you mean, those are not coverage gaps, rather financial cost sharing. Coverage gaps would infer illnesses that Medicare does not cover, and that's not the case.

Daniel Brechin · Answer

Medicare was never intended to be the only coverage for your insurance. Medicare A&B were set to be alone when first developed. However, Medicare supplement programs were developed to supplement the part A &B. So for a small premium the supplement company cover to part A and Part B. In 1995 Medicare Advantage plans came about. They received money from Medicare. This was done by having a 0 premium and a max out of pocket that were 2000.00. The best thing about would be your cost was what you needed.

It's difficult to answer why Medicare has so many coverage gaps, and also to know which gaps you're referring to that would be important for you. There are plans that help fill in the gaps, i.e. Medicare Supplement plans were designed for this purpose. There are a variety of plan options, premiums will vary based on the plans so you get to choose how much or how little you want gap coverage.
