Turning 65? The Medicare Decisions That Could Matter Even More at 80
When someone is getting ready to turn 65, I often hear the same question: Which Medicare plan should I choose? I understand why people want a simple answer. They may have a friend who loves a particular plan, or they've seen advertisements promising extra benefits. But the more important conversation is usually about what they need, what they can afford, and what they might need later.
I've met people who were genuinely surprised to learn that Medicare isn't automatically free at 65. Some of the clients I've spoken with came to the United States from other countries and were approaching Medicare for the first time. They knew the name but not the details. They didn't know what Medicare Advantage was, had never heard of Medigap, and assumed that reaching their 65th birthday meant their medical bills would simply be taken care of.
One point that often causes confusion is work history. In general, about 10 years of Medicare-covered employment, often expressed as 40 work credits, are needed for premium-free Part A, although a spouse's work record may also help someone qualify. Not having enough credits does not automatically mean a person cannot get Medicare; some people can enroll and pay a Part A premium if they meet the other eligibility rules. Part B generally has its own monthly premium. For someone who has spent years working and paying taxes without ever having to understand these rules, that can be a difficult surprise.
I don't think people should have to become insurance experts to make a healthcare decision. They do, however, deserve to know the questions to ask. And one question is too often missing: What would this choice mean if my health looked very different 10 or 15 years from now?
The price you see is not always the cost you pay
A Medicare Advantage plan with a $0 additional monthly premium can be appealing, especially to someone preparing to live on a fixed retirement income. Some plans include prescription drug coverage and benefits such as routine dental, vision, or hearing care. Those features may be a good fit for many people.
But a $0 plan premium does not mean $0 healthcare costs. Most members still owe the Medicare Part B premium unless they qualify for help or their plan provides a giveback. Depending on the plan and service, they may also pay copayments, coinsurance, or deductibles for visits, tests, hospital care, or ongoing treatment. Medicare Advantage plans have annual out-of-pocket limits for covered Part A and Part B services, which is an important safeguard. Even with that limit, costs can be difficult to manage. Premiums, prescription drug expenses, and some other costs generally do not count toward that medical limit.
Original Medicare works differently. Part A helps cover inpatient hospital care and Part B helps cover outpatient medical services. It generally lets a person see providers anywhere in the country who accept Medicare. But Original Medicare alone does not have an annual out-of-pocket maximum for covered Part A and Part B services. Without other coverage, the patient's share can add up.
Medigap, also called Medicare Supplement Insurance, is designed to help pay certain out-of-pocket costs left by Original Medicare. It isn't a type of Medicare Advantage plan, and the two aren't meant to be used together. People who choose Original Medicare and Medigap generally need a separate Part D plan if they want prescription drug coverage. They also pay a Medigap premium, which can rise over time. So the comparison is not simply "free versus expensive." It is a comparison of how and when you pay, the coverage rules, and the level of financial uncertainty you are comfortable with.
Does everyone pay the same amount for Medicare, or does my premium depend on my situation?
Not everyone pays the same amount for Medicare.Your costs can depend on your income, work history, and the coverage you choose.
Most people don't pay a monthly premium for Part A, but Part B has a monthly cost that may be higher depending on your income.
My advice is to review your options carefully, because you may also qualify for programs that help lower your costs.
A client whose health changed
This became especially personal for me when a client who had been doing well with their health suddenly needed dialysis. Someone who had not been living with a major medical condition was now facing regular treatment and the disruption that comes with it. On top of that, the costs the client faced under a Medicare Advantage plan were difficult to manage.
What I remember most is not a particular bill. It is how upsetting it was to see someone dealing with a serious health problem while also worrying about whether they could keep up financially. Trying to understand the available options and find a workable path was not simple.
To be clear, medically necessary dialysis is covered by Medicare, including through Medicare Advantage plans, subject to the applicable coverage rules. Medicare Advantage also has cost-sharing protections and annual limits for covered medical services. The problem in this situation was not that dialysis was categorically excluded. It was that the client's share of the costs, alongside the realities of living on a limited income, had become hard to bear.
Under Original Medicare, outpatient dialysis generally involves 20% coinsurance after the Part B deductible. A Medigap policy that covers that coinsurance may reduce the patient's exposure, but someone cannot assume they will be able to buy such a policy later, especially after a serious diagnosis. The details always depend on the coverage a person has and the rules that apply to them.
I share this experience without identifying the client because I think it raises a question worth asking before anyone needs intensive medical care: If my health changes, could I still manage the costs of the plan I choose today?
My Medicare Advantage plan with UHC has been closed and will not be available next year. Can I switch to enrolling in a Medicare Supplemental plan for 2027 without having to pre-qualify
Yes! The good news is, you may have some special protections! If UHC is ending your Medicare Advantage plan for 2027, you may be able to switch to Original Medicare and get certain Medicare Supplement plans without having to qualify based on your health.My advice? Keep the letter you received from UHC and start looking at your options early.
You generally have up to 63 days after your coverage ends to apply, but I wouldn't wait until the last minute!
The doctors you can see matter, too
Money isn't the only consideration. Some people have long-standing relationships with particular specialists. Others travel between states, spend part of the year near their children, or want flexibility if they need treatment somewhere else in the country.
With Original Medicare, patients can generally use any doctor or hospital in the United States that accepts Medicare and is willing to treat them. Standard Medigap coverage helps with certain remaining costs; it doesn't create that provider access. With Medicare Advantage, the experience depends on the plan. Many HMO plans use networks and may require referrals. PPO plans may offer more out-of-network options, often at a higher cost. Certain services may also require prior authorization.
That doesn't make one system universally better. Some people are very happy with the coordinated care and extra benefits of their Medicare Advantage plan. Others place a higher value on the broad provider choice available through Original Medicare. Someone who rarely travels and already has preferred doctors in a plan's network may see the decision differently from someone who regularly moves between Florida and another state. It is worth checking the doctors, hospitals, prescriptions, and pharmacy arrangements that actually matter to you, rather than assuming every plan works the same way.
The choice you can make at 65 may be harder to make at 80
Here is one part of Medicare I wish more people understood early: choosing Medicare Advantage today and changing your mind years later does not automatically guarantee that you can buy Medigap.
Under federal rules, people generally have a one-time six-month Medigap Open Enrollment Period that begins when they are 65 or older and enrolled in Medicare Part B. During that period, an insurer generally cannot reject an application for a Medigap policy it sells because of existing health conditions. After that window, medical underwriting may apply. Depending on state law and the person's circumstances, an insurer might charge more or decline an application.
There are exceptions, including certain guaranteed-issue protections and trial rights. Some states provide additional opportunities to enroll. But those exceptions should never be assumed without checking. This is also different from Medicare's Annual Open Enrollment Period, when people can make changes to Medicare Advantage or Part D coverage; that annual window does not automatically create a new right to purchase Medigap.
That's why I encourage people to understand the options they could lose as well as the benefits they would gain. A plan that fits comfortably at 65 may still be a reasonable choice. The important thing is to make that choice with open eyes.
I have a SCAN Medicare Advantage plan and turn 66 in November. Can I switch back to Original Medicare during this enrollment period?
Yes, absolutely!You can switch from your SCAN Medicare Advantage plan back to Original Medicare during Open Enrollment, from October 15 through December 7.
Your new coverage would begin January 1. Turning 66 doesn't affect your ability to make this change. Just remember, you may need a separate prescription drug plan, and if you're considering a Medicare Supplement, it's important to check your eligibility before switching.
Planning for 2027 without losing sight of the years after it
As people review their Medicare choices for 2027, the usual Annual Open Enrollment Period runs from October 15 through December 7, 2026, with plan changes generally taking effect January 1, 2027. That period is mainly for changing Medicare Advantage and Part D coverage. Someone signing up for Medicare for the first time around age 65 follows different enrollment rules and should not assume they need to wait until January.
Before comparing plans, I would encourage anyone approaching Medicare to check 3 basic things: when they are eligible to enroll, which doctors and medicines they rely on, and what they could realistically afford during a difficult medical year. If they are still working, they should also check whether their employer coverage allows them to delay Part B without a penalty. Missing a deadline can have consequences, and not every type of employer-related coverage is treated the same way.
For people with limited income, assistance may be available through Medicare Savings Programs, Extra Help for prescription drug costs, or Medicaid, depending on eligibility. Those programs are worth investigating before concluding that a necessary treatment or a particular coverage arrangement is simply unaffordable.
I don't believe there's one Medicare answer for everyone. A retiree watching every monthly expense may reasonably prioritize a low additional premium. Another person may choose to spend more each month in exchange for more predictable costs under Original Medicare and Medigap. Both deserve a careful explanation.
We all hope to stay healthy as we get older. But good planning isn't only about the year we turn 65. It's also about the years that follow, when our health, finances, and priorities may change. A Medicare decision should make sense for the person we are today while giving honest consideration to the person we may be at 75 or 80.
