How to Plan for Health Insurance in Retirement: Coverage Options Explained

Medicare sounds complicated, and without employer health insurance coverage, finding the right policy before age 65 feels daunting. So, inevitably, most of the families I work with want to know how to plan for health insurance in retirement. 

If you want a smooth transition into retirement with less stress, you’ll want to have a solid plan in place for retirement health coverage. In this article, the Stage Ready team—as your Dayton, Ohio financial planning experts—will discuss the important concepts you’ll need to understand as you build your healthcare strategy.

Key Takeaways

• Timing Your Enrollment is Non-Negotiable: Missing your Initial Enrollment Period (IEP) at age 65 or your Special Enrollment Period (SEP) after leaving a large employer can lead to permanent 10% Part B premium penalties for every 12-month period you were eligible but delayed.
• Income Dictates Your Premiums: Whether you are under 65 using the ACA Marketplace or over 65 on Medicare, your Modified Adjusted Gross Income (MAGI) determines your costs. In 2026, the ACA “subsidy cliff” returns at 400% of the Federal Poverty Level, and Medicare IRMAA surcharges begin for individuals making over $109,000.
• Planning Means More Than Comparing Costs: Successful retirement healthcare planning involves coordinating your specific doctors and prescriptions with tax-efficient withdrawal strategies. You’ll need to build a proactive plan for services Medicare doesn’t cover, such as dental, vision, and long-term care, to protect your retirement portfolio.

Health Insurance Planning Is Not the Same as Cost Planning

When you’re working, your employer hands you a few health insurance options, and you pick the one that seems good enough for the premium. In retirement, your choices are more complicated.

Health insurance planning involves a lot more than just being able to afford the cost of the policy, including:

• Staying in Sync with your Doctor: You’ll want to make sure your favorite doctors and hospitals are in-network.
• Don’t Forget Your Prescriptions: This isn’t always easy, but you’ll need to make sure your retirement health coverage includes your prescriptions at an affordable cost.
• Coordinate with a Health Savings Account (HSA): If you’re retiring before 65, you might want a plan that allows you to continue contributing until Medicare kicks in.
• Planning Other Medical Costs: Health insurance and Medicare won’t cover your dental and vision bills. It also won’t pay for your long-term care later in life. You’ll need to figure out coverage or some way to pay for these services.
• Travel Logistics: If you want to travel in retirement, you’ll need to find coverage that works when you’re out of town. For example, some plans have strict service areas, while Traditional Medicare works anywhere in the U.S. that accepts Medicare.
• Tax Coordination (IRMAA & Premium Tax Credits): In retirement, you might have to pay more for health insurance if you make too much money. With Medicare it’s called an IRMAA surcharge. With healthcare.gov plans, you might lose premium tax credits. 

Step One: Know When You’re Retiring (Pre-65 vs. 65+)

When it comes to retirement health insurance planning, a good starting point is to figure out if you’ll be retiring before or after Medicare coverage, which normally begins at 65. 

Retiring Before 65

If you stop working before age 65, you’ll enter a gap period where you’re responsible for finding and paying for your own health insurance coverage until Medicare kicks in. For example, if you retire at 62, you’ll have to find coverage for 3 years. 

Paying for pre-Medicare health insurance can feel pretty jarring because you’re moving from a subsidized employer plan to paying the full bill yourself. The good news is that there are a few ways to bridge the gap including your spouse’s policy, retiree government coverage, the ACA Marketplace, and COBRA.

Retiring At or After 65

Unless you’ve already qualified for Medicare due to a disability, you’ll get access at age 65. Your Initial Enrollment Period is a seven-month window that begins three months before you turn 65, includes your birth month, and ends three months after.

If you’re retiring after 65, you won’t have to sign up for Medicare Part B until you’ve ended your employer health coverage. If your current employer has 20 or more employees, you can delay that part of the coverage without a penalty. 

Many people still choose to sign up for Medicare Part A at 65 because it’s usually premium free and can help cover hospital costs that your employer plan doesn’t. When you keep employer coverage past 65, it’s helpful to know who pays first. If your employer has 20 or more employees, your group plan is the primary payer and Medicare is secondary. If the company has fewer than 20 employees, the opposite is true. Missing this distinction could mean your employer plan denies your claims because they expect Medicare to pay first.

That said, if you want to keep contributing to your health savings account (HSA), you can’t be enrolled in any part of Medicare. In that situation, you’d want to delay both Part A and Part B until you’re ready to fully retire. Once you do leave your job, you’ll trigger an eight-month window to get signed up.

If You Retire Before 65: Bridge Coverage Options

Here are some common instruments available to help you fill the gap between retirement and Medicare at age 65.

Spousal Employer Coverage

If your spouse is still working and has access to a group health plan, joining their policy is usually the most affordable way to bridge the gap to Medicare. According to the Kaiser Family Foundation 2025 survey, the average worker contributes about $6,850 per year (roughly $570 a month) for family coverage. 

While spousal coverage is often the cheapest option, it’s worth a comparison check:

• Spousal Coverage: Usually features the lowest premiums and manageable deductibles.
• ACA Marketplace: Might be cheaper if your retirement income is low enough to qualify for significant tax credits but probably be a high deductible health plan.
• COBRA: Likely the most expensive route, as you’re paying 100% of the premium plus an administrative fee.

Government and Public Service Plans

If you’re a retired Ohio teacher (STRS), school employee (SERS), state employee (OPERS), or police officer/firefighter (OP&F), you may have access to specialized retiree health programs or stipends. Similarly, retired military members and federal employees can often carry TRICARE or FEHB into retirement. These plans are designed to bridge you to age 65, at which point they typically shift to become a supplement to your Medicare coverage.

ACA Marketplace Plans

If you have a longer gap between retirement and turning 65, you may want to consider finding coverage using the Affordable Care Act (ACA) Marketplace (healthcare.gov). These policies can be pretty expensive and feature high deductibles but if you have low enough income, you could qualify for premium tax credits. You can choose to have your credit sent directly to your insurance company each month so you pay less out-of-pocket, or you can claim it on your tax return.

In 2026, If your modified adjusted gross income (MAGI) exceeds 400% of the federal poverty level, which is $63,840 for an individual or $86,560 for a family of two, you lose the ability to qualify for tax credits.

ACA plans are divided into tiers that balance your monthly bill against your out-of-pocket costs. The premiums and deductibles mentioned below are based on 2026 data from the Peterson-KFF Health System Tracker and represent the gross premiums before any tax credits are applied:

• Bronze: These policies have the lowest monthly premiums, averaging around $456. However, they come with high average deductibles of $7,186. 
• Silver: These policies have average premiums of around $625/mo and a $5,304 average deductible.
• Gold and Platinum: These carry the highest monthly premiums but offer much lower deductibles, averaging $1,722 for Gold plans.

Example: If you and your spouse are 62 and retiring with a $1 million portfolio and you take $50,000 a year from your taxable brokerage account (which has little taxable impact) rather than your traditional IRA, you could keep your MAGI low. In 2026, this strategy could mean paying a subsidized premium of between $300-$400/mo instead of around $1,300-$1,400.

COBRA Coverage

If you plan to retire shortly before you turn 65, COBRA might be a helpful bridge because it lets you keep your current health coverage for about 18 months post separation. There are also qualifying events can lengthen COBRA retiree health coverage for your family, including: 

• A disability (extending coverage up to 29 months) 
• The death of a covered employee (extending coverage for a spouse or dependent child for up to 36 months)

If your retirement gap is longer than these windows, COBRA won’t get you all the way to Medicare.

While you’re employed, your company pays a large portion of your health insurance premium. With COBRA, you’re responsible for 100% of that premium (including your employer’s portion), plus a 2% administrative fee. This means that if your employer-sponsored plan costs $1,500/mo and you were only paying $400 of that, your new out of pocket premium under COBRA would jump to around $1,530/mo.

One COBRA feature that’s less well known is that if a retiring spouse enrolls in Medicare Part A or B before they stop working, it can trigger a special rule that allows the younger spouse to keep COBRA for up to 36 months from the date of that Medicare enrollment. 

Example: Let’s say you’re 65 and your spouse is 63 and you plan to retire in six months. If you enroll in Medicare Part A today, your spouse could potentially receive COBRA for up to 30 months after you actually leave your job (36 months minus the 6 months you were still working). This would bridge them until they reach their own Medicare eligibility at 65.

Medicare Planning at Age 65

Once you turn 65, you’ll be eligible for Medicare, which is broken into different parts that cover specific types of health care.

Understanding Medicare Parts

• Part A (Hospital Insurance): Covers inpatient hospital stays, skilled nursing facility care, hospice, and some home health care. Most people won’t pay a premium for Part A, having paid into it previously via taxes.
• Part B (Medical Coverage): Covers your doctor visits, outpatient treatments, preventive care, and medical equipment. The lowest monthly premium is $202.90 in 2026 but can be increased by having a higher MAGI (IRMAA Surcharge).
• Part C (Medicare Advantage): A private insurance alternative to traditional Medicare that bundles Parts A, B, and usually D into a single plan. Many Part C plans have a $0 monthly premium, but you’ll still pay your Part B premium to the government.
• Part D (Prescription Drugs): Helps cover the cost of prescription drugs and is run by private insurance companies. In 2026, the average premium is around $34.50 but just like Part B, it can be higher based on your MAGI (IRMAA Surcharge).

Traditional Medicare (Part A and B) vs. Medicare Advantage (Part C)

When you sign up for Medicare, you’ll need to decide whether to choose traditional Medicare or Medicare Advantage. This decision determines your access to doctors, out-of-pocket limits, and how easily you can switch plans in the future.

Traditional Medicare (Part A and B) + Medigap

Traditional Medicare has the highest level of flexibility, allowing you to see any doctor in the country that accepts your insurance. Unfortunately, Traditional Medicare has no cap on what you’ll spend out-of-pocket, so most retirees add a Medigap (Supplement) policy. These supplement policies can eliminate most of your unpredictable co-pays and deductibles, but with a higher monthly premium. It’s important to note that Medicare Part D has an out of pocket cap of $2,100 for prescription drug expenses in 2026. 

You have a one-time, six-month window when you first sign up for Part B to buy any Medigap plan without a health evaluation. If you decide to purchase a Medigap plan later, insurers in most states can use medical underwriting, meaning they can charge you more or deny coverage based on your health history.

Medicare Advantage (Part C)

Medicare Advantage plans act as a bundled private alternative to traditional Medicare. They bundle Medicare Part A, B, and D and usually include extra benefits like drug coverage, gym memberships, dental, and vision coverage. These plans are popular because they have lower monthly premiums. That said, you’ll have higher costs in the forms of copays and deductibles when you use the insurance. 

According to Mutual of Omaha, Advantage plans have a Maximum Out-of-Pocket (MOOP) limit, capped at $9,250 in 2026. You’re responsible for co-pays and deductibles until you hit that limit. If you join Medicare Advantage at age 65, you’ll have 12 months to switch back to Original Medicare and buy a Medigap plan without health underwriting. 

Enrollment Windows

If you miss your sign up window, you could face permanent premium penalties or a gap in coverage. Here is a basic breakdown of your enrollment window for Medicare based on common situations:

If You Are…	Your Enrollment Window
Turning 65	Initial Enrollment Period (IEP): 7 months (starts 3 months before your birth month).
Retiring after 65 (Large Employer 20+)	Special Enrollment Period (SEP): 8 months after your job or health coverage ends.
Working at 65 (Small Employer < 20)	Must sign up during IEP. Your small business plan usually becomes secondary to Medicare at 65.
Missed your window (and no SEP)	General Enrollment Period: January 1 – March 31 each year. Late penalties may apply.

Supplemental Coverage: Filling the Gaps

Medicare doesn’t cover everything. To keep your retirement plan fine-tuned, you’ll need to consider how you’ll pay for these extra health care costs:

• Medigap
• Prescription Drug Plans
• Dental, Vision, Long-Term Care Insurance

Medigap

Mentioned earlier, Medigap plans (Medicare supplement insurance) help you pay your deductibles and co-insurance expenses because Traditional Medicare doesn’t have an out-of-pocket max. These optional policies can be helpful if you have chronic medical conditions and expect to be visiting the doctor regularly.

Prescription Drug Plans

Medicare Part D is optional prescription drug coverage. Even if you don’t currently take medications, you should consider enrolling when you turn 65 to avoid permanent late penalties. If you decide not to enroll, you’ll face a monthly penalty if you sign up later and have gone 63 days or more without coverage that Medicare considers creditable. You’ll pay this extra surcharge for as long as you have Medicare drug coverage. Since the base premium increases each year, your penalty will also grow over time.

You can avoid penalties by signing up during your seven-month Initial Enrollment Period. If you’re already enrolled, you can change your plan each year during Open Enrollment (October 15 to December 7) if you find a more cost-effective policy.

Dental, Vision, Long-Term Care Insurance

Medicare doesn’t cover dental work, vision exams, and long-term care costs. You’ll need to build a strategy for these services so they don’t eat into your retirement portfolio later.

When it comes to dental and vision coverage, you could choose a Medicare Advantage plan, because it often bundles dental and vision benefits into your monthly premium. If you think you’ll need Traditional Medicare instead, you’ll need to purchase separate dental and vision insurance or pay out-of-pocket.

Since Medicare won’t cover extended nursing home stays or private home-care, you’ll need a plan. Note that I said plan, not insurance. You could explore independent long-term care insurance to shift that risk to an insurance company but you don’t have to have insurance if you have enough cash to pay for your care. Instead you could max fund your Health Savings Account (HSA) while you’re still working. If you invest these funds, you could be building a tax-free instrument specifically for medical and long-term care expenses later in life. 

Keep in mind that you can’t contribute to an HSA once you’re enrolled in any part of Medicare. If you’re healthy and want to keep building your account, you might consider delaying Medicare enrollment as long as you’re covered by a qualifying large-employer plan.

At the end of the day, a plan for long-term care is simply noting where you want to be cared for, who will take care of you, and how you’ll pay for it. 

Common Health Insurance Planning Mistakes in Retirement

Here are a few of the most common retiree health insurance pitfalls you’ll want to avoid:

• Underestimating Costs: You might assume that Medicare is low cost or even free. In reality, a healthy couple retiring at age 65 in 2026 can expect to spend between $315,000 and $400,000 on health care expenses throughout retirement, not counting long-term care.
• Ignoring Timelines: Medicare is really strict about timelines. If you miss your window for Part B, you’ll face a 10% penalty for every 12-month period you were eligible. If you miss Part D, you’ll face a 1% monthly penalty if you go more than 63 days without creditable coverage. These are permanent surcharges added to your monthly bill.
• Not Understanding IRMAA: Medicare looks at your tax returns from two years ago to determine your current premiums. If you had a high-income year just before retiring, you could be in for a surprise surcharge. If your income drops significantly because you’ve retired, you don’t have to just accept a high IRMAA surcharge. You can file an appeal using Form SSA-44 (Life-Changing Event). This tells Social Security that your two-year-old tax return no longer reflects your current financial reality, potentially saving you thousands in annual premiums.
• Failing to Plan: Choosing a plan based on your neighbor’s advice is a recipe for frustration. Your coverage should be built around your specific doctors and medications.

A Step-by-Step Health Insurance Planning Checklist

1. Confirm your retirement date to understand your enrollment window. For example, if you’re retiring at 65, your window opens three months before your birthday.
2. Create a list of every doctor you see and every prescription you take, including dosages. 
3. Review your tax return from two years ago. If your income was high due to a business sale or a bonus, you’ll want to know if you qualify for an appeal to lower your IRMAA surcharges.
4. I recommend my clients work with an independent retirement health insurance consultant, like RetireMed, in Dayton, Ohio. Since their benefits specialists aren’t paid commissions, they can objectively compare plans based on your health and income situation. They can also help you review your plan yearly as your health changes.
5. Once you’re in retirement, work with your financial advisor to monitor your Modified Adjusted Gross Income (MAGI). Strategic withdrawals from Roth IRAs or HSAs can help you stay below the IRMAA thresholds and keep your premiums low.

Frequently Asked Questions (FAQs)

Do I automatically get Medicare when I turn 65?

Not necessarily. You only get Medicare automatically if you’re receiving Social Security benefits. If you aren’t, you’ll need to actively sign up through the Social Security Administration during your seven-month Initial Enrollment Period. If you miss your window, you’ll face lifetime late-enrollment penalties.

How much will I pay for prescription drugs in 2026?

For 2026, there’s now a hard $2,100 out-of-pocket cap on what you’ll pay for covered Part D prescriptions each year. Once you hit that limit, you won’t pay a copayment or coinsurance for the rest of the year. This out of pocket limit is in addition to your Part D premiums. 

Should I choose Traditional Medicare or Medicare Advantage?

Your choice depends on your health, how much you plan to travel in retirement, and how you feel about out of pocket costs. Traditional Medicare plus a Medigap supplement offers the most flexibility because you can see any doctor in the country who accepts Medicare, but you’ll have higher premiums. Medicare Advantage acts as a private alternative with lower premiums and extra perks like dental or vision, but you’re restricted to a specific network of providers and will face higher copays and deductibles.

Can I still contribute to my HSA once I turn 65?

Only if you haven’t enrolled in any part of Medicare. Once you’re enrolled in Part A or Part B, you’re no longer allowed to contribute to your HSA. However, you can still use the funds already in your account to pay for qualified medical expenses tax-free, including your Medicare premiums and long-term care costs.

How do I avoid the Medicare “High-Income” surcharge (IRMAA)?

Medicare looks at your Modified Adjusted Gross Income (MAGI) from two years ago to determine if you’ll pay a higher premium. In 2026, those surcharges kick in for individuals making over $109,000 or couples over $218,000 on their 2024 tax return. To keep your premiums low, we consider strategies like Roth conversions or using HSA funds to manage your taxable income during important look-back years.
