Fidelity Has a Blunt Message for Anyone Counting on Medicare in Retirement

If Medicare is the center of your retirement health care plan, here's the uncomfortable part: Your red, white, and blue card isn't the same thing as a paid-in-full receipt.

Fidelity's latest retiree health care estimate puts the lifetime cost for a 65-year-old retiring in 2026 at $185,500 for health care and medical expenses throughout retirement, assuming enrollment in Original Medicare and Part D. CMS also set the 2026 standard Medicare Part B premium at $202.90 per month and the Part B deductible at $283.

That doesn't mean Medicare is a bad deal. It means you may need a separate plan for the bills Medicare leaves behind to try to avoid financial mistakes when money is stretched thin.

The blunt warning

Fidelity's estimate is a retirement reality check. Even with Medicare, a new retiree could still face premiums, deductibles, copays, coinsurance, and other health costs over time. Fidelity says its estimate includes Medicare Part B and Part D premiums, cost sharing, and certain services Original Medicare excludes. It does not include over-the-counter medications, most dental services, or long-term care.

The key point is simple: Medicare can reduce your exposure, but it usually doesn't erase it. If your retirement plan assumes Medicare covers almost everything, your budget might be too thin.

That gap exists because Medicare has built-in cost sharing. It also leaves out some common needs, especially if you're using Original Medicare without added coverage.

The 2026 bill

The 2026 standard Part B premium is $202.90 per month. That comes out to $2,434.80 per year before you pay for prescriptions, supplemental coverage, dental care, or out-of-pocket treatment costs.

Part B also has a $283 annual deductible in 2026. After you meet it, you typically pay 20% of the Medicare-approved amount for many covered services under Original Medicare.

Hospital coverage has its own cost sharing. The 2026 Medicare Part A inpatient hospital deductible is $1,736 per benefit period, which means a serious hospital stay could still come with a sizable bill.

What Medicare misses

Original Medicare generally doesn't cover routine dental care, routine vision care, hearing aids, or most long-term custodial care. Those are standard exclusions.

This is where retirees often get surprised. A crown, new glasses, hearing aids, or help with daily activities might be medically important to you, but that doesn't mean Medicare treats the cost the same way.

Some Medicare Advantage plans may include dental, vision, hearing, or other extra benefits. That can help, but you still need to compare the actual plan rules, provider network, drug list, prior authorization rules, and annual out-of-pocket limit.

Drug cost relief

There is some good news for prescriptions. In 2026, the Medicare Part D out-of-pocket cap is $2,100 for covered drugs.

That cap can matter if you take expensive medications. It could protect you from runaway Part D costs once your covered out-of-pocket spending reaches the annual limit.

But the cap doesn't make every medication free. It also doesn't cover all health care spending, premiums, dental bills, hearing aids, noncovered drugs, or many services outside your plan's rules. The relief is real, but it isn't a full retirement health care budget.

Original or Advantage

Your costs can look very different depending on whether you use Original Medicare, add a Medigap policy, enroll in a stand-alone Part D plan, or choose Medicare Advantage.

Original Medicare gives you broad access to providers that accept Medicare, but it doesn't have a yearly out-of-pocket maximum for Part A and Part B services. That is the gap Medigap is designed to help fill, though Medigap comes with its own premium.

Medicare Advantage plans do have annual out-of-pocket limits for covered Part A and Part B services. They might also include extras. Some Medicare Advantage plans charge no additional plan premium, although you generally still pay your Part B premium. Depending on the plan, provider networks, specialist referrals, prior authorization, and drug coverage rules may apply.

Long-term care

Long-term care deserves its own line in your retirement plan because this is one of the biggest misunderstandings around Medicare. Medicare generally doesn't pay for ongoing custodial care if the main help you need is bathing, dressing, eating, or supervision.

Medicare may cover limited skilled nursing facility care after a qualifying hospital stay, and it may cover certain home health services when you meet specific rules. Coverage is limited and stops short of open-ended nursing home care or full-time help at home.

Medicaid may help with long-term care for people who meet income and asset rules, but that is a different program with eligibility limits. If you have savings you hope to protect, this is a gap to plan for before a crisis hits.

Your next step

Medicare open enrollment runs from October 15 through December 7 each year. During this window, you can change Medicare Advantage or Part D coverage, or switch between Original Medicare and Medicare Advantage, with changes generally effective Jan. 1. This window does not guarantee that you can buy a Medigap policy without medical underwriting.

Look beyond the monthly premium. Check your doctors, hospitals, prescriptions, pharmacy, deductibles, copays, coinsurance, annual out-of-pocket maximum, dental coverage, and prior authorization rules.

If you're not on Medicare yet, build health care into your retirement number now. If you're eligible to contribute to a health savings account before Medicare, that could give you tax-advantaged money for future qualified medical expenses.

Your HSA contribution limit is zero for months you're enrolled in Medicare, including any months of retroactive Medicare coverage. You can still use existing HSA funds for qualified medical expenses.

Bottom line

Fidelity's warning comes down to this: Medicare helps, but it doesn't replace a complete financial plan for retirement health care. If you're looking to save money in retirement, understanding these numbers can help you see the bigger picture. 

You may still need cash for premiums, deductibles, prescriptions, dental work, hearing, vision, and long-term care. Review your coverage during open enrollment, price your regular medications, and keep a separate health care cushion in your retirement budget.

Medicare can be one of the most valuable benefits you receive in retirement. It just might not be enough by itself.
