Medicare Seems Like a Lifesaver at First—Until You Start Paying for Services You Thought Were Covered

Key Takeaways

• Medicare can leave you with unexpected out-of-pocket costs if you assume everything is covered automatically. Many services require coinsurance, deductibles, or aren’t covered at all.

• Understanding what Medicare does and doesn’t pay for in 2025 can help you avoid surprises and better plan your retirement budget.

It Feels Like Relief at First: Enrolling in Medicare

You become eligible for Medicare when you turn 65, and for many, that initial enrollment feels like a major win. After years of high premiums, employer-based insurance shifts, or limited coverage, the idea of government-supported healthcare sounds like a major relief.

Medicare promises access to hospitals, doctors, prescriptions, and more. But soon after you begin using your coverage, you may realize there are costs that never came up in casual conversations or media messages. Services you thought would be free come with bills. Coverage you assumed was included ends up requiring add-ons or outside policies. And instead of saving money, you may start spending more than you expected.

What Original Medicare Actually Covers

Original Medicare is made up of Part A and Part B:

• Part A helps cover inpatient hospital care, limited skilled nursing facility stays, hospice, and some home healthcare.

• Part B covers outpatient care such as doctor visits, preventive services, lab work, and durable medical equipment.

But neither part covers everything. Many retirees mistakenly believe that once they enroll, they won’t face any medical expenses. That’s simply not the case.

Here are just a few things that Original Medicare does not fully cover in 2025:

• Prescription drugs (not included under Part A or B)

• Routine dental, vision, and hearing services

• Long-term custodial care (like help with bathing or dressing)

• Foreign travel medical coverage

• Most chiropractic care, acupuncture, or alternative therapies

The Cost Breakdown You Weren’t Expecting

Even services that Medicare does cover often come with cost-sharing. That means deductibles, coinsurance, or copayments are part of the deal.

Medicare Part A in 2025

• If you worked and paid Medicare taxes for at least 40 quarters, you don’t owe a monthly premium.

• The inpatient hospital deductible is $1,676 per benefit period.

• Days 1–60 are covered fully after you pay the deductible.

• Days 61–90 require a daily coinsurance of $419.

• Lifetime reserve days (91 and beyond) cost $838 per day.

• Skilled nursing facility care: first 20 days are free, then $209.50 per day for days 21–100.

Medicare Part B in 2025

• The monthly premium is $185.

• The annual deductible is $257.

• After you meet the deductible, you pay 20% of the Medicare-approved amount for most outpatient services.

This 20% may not sound like much until you have a diagnostic scan, outpatient surgery, or frequent therapy visits. These costs can add up quickly without any out-of-pocket cap under Original Medicare.

Why You May Need Additional Coverage

Because Original Medicare doesn’t include a maximum out-of-pocket limit, your expenses can grow with each additional medical need. To deal with this, many beneficiaries explore:

• Medicare Supplement Insurance (Medigap): Helps pay for deductibles, coinsurance, and other out-of-pocket costs.

• Medicare Advantage (Part C): Offers bundled coverage through private insurance, often with added benefits. (General features only mentioned, no plan specifics.)

• Part D Prescription Drug Plans: Covers medications but may still have deductibles and cost tiers.

However, none of these are free. Each comes with its own premiums, restrictions, and enrollment rules. You need to assess how each fits with your healthcare usage and financial situation.

The High Cost of Missing Enrollment Windows

If you delay enrollment in certain parts of Medicare, you may face lifetime penalties. Here are some key time-sensitive costs to understand:

• Late Enrollment Penalty for Part B: If you miss your Initial Enrollment Period and don’t qualify for a Special Enrollment Period, your premium goes up by 10% for every full 12-month period you were eligible but didn’t sign up.

• Late Enrollment Penalty for Part D: Adds 1% of the national base premium for each month you went without coverage after becoming eligible.

These penalties are added to your monthly premium for life. And they apply even if you later get coverage through another method.

Prescription Drugs: The Hidden Giant

In 2025, Medicare introduces a $2,000 annual cap on out-of-pocket drug costs for those enrolled in Part D. This is a welcome relief for many, especially those with chronic illnesses.

However, you still face other drug-related costs:

• Plan premiums

• Deductibles (up to $590 in 2025)

• Tiered copayments or coinsurance for brand-name and specialty medications

The new cap only applies after you hit the limit through spending, so budgeting early in the year is critical.

Dental, Vision, and Hearing: Common Oversights

One of the most misunderstood parts of Medicare is the lack of routine dental, vision, and hearing coverage under Original Medicare.

• Dental: Cleanings, fillings, dentures, and root canals are not covered.

• Vision: Routine eye exams and eyeglasses are not included.

• Hearing: Hearing aids and related exams are excluded.

To get these benefits, you must either pay out of pocket or explore private supplemental policies. These expenses can easily run into hundreds or thousands of dollars annually, depending on your needs.

Home Health vs Long-Term Care: A Crucial Difference

Medicare covers skilled home health services like physical therapy or nursing after hospitalization, but it does not cover custodial long-term care if all you need is help with daily tasks like bathing or eating.

This difference becomes financially significant. Custodial care in assisted living or nursing homes can cost tens of thousands per year. Many families mistakenly believe Medicare will help, only to face full out-of-pocket responsibility when the time comes.

Emergency Care While Traveling

Medicare usually does not cover healthcare costs outside the United States, with only rare exceptions.

If you travel abroad and require hospitalization, you are likely responsible for 100% of the bill unless you have supplemental coverage. Similarly, even domestic travel can present problems if you’re away from a local network or out of area.

Some Medicare Advantage plans may offer emergency coverage overseas, but again, plan rules vary and coverage may be limited.

Copayments and Prior Authorizations in Medicare Advantage Plans

If you choose to enroll in a Medicare Advantage plan, you may gain additional benefits, but you also may encounter:

• Required copayments for many services

• Prior authorization for procedures or referrals

• Network restrictions for doctors and hospitals

While some beneficiaries prefer the simplicity of an all-in-one plan, others find the structure limiting, especially if their provider choices are narrowed or authorizations delay care.

Why a Cost Estimate Isn’t Always Reliable

You might try estimating your yearly Medicare expenses by adding up premiums, deductibles, and coinsurance. That can work well for routine health needs.

But here’s where the issue lies: unexpected health events can throw your budget off completely. A sudden hospitalization, new diagnosis, or specialty drug prescription can move your cost from manageable to overwhelming. Since Original Medicare lacks a cap on out-of-pocket costs, your potential financial exposure is virtually unlimited unless you secure supplemental protection.

The Role of Annual Plan Reviews

Every fall, Medicare holds an Open Enrollment Period from October 15 through December 7. This is your opportunity to:

• Switch between Original Medicare and a Medicare Advantage plan

• Change from one Medicare Advantage plan to another

• Join or switch a Part D plan

• Drop Part D coverage

Failing to review your plan annually can mean overpaying or missing out on coverage that better fits your current needs. Formularies, networks, premiums, and cost-sharing often change from year to year.

What to Do If You’re Already Feeling Overwhelmed

You’re not alone. Many Medicare beneficiaries are surprised by the actual costs they face once enrolled. If you feel unsure about what coverage to choose or how to protect yourself from unexpected bills, help is available.

Getting Help Before It Costs You

Avoiding surprises with Medicare isn’t just about reading the fine print. It’s about taking control of your healthcare plan before it becomes a financial problem. You need to:

• Know what Original Medicare does and doesn’t cover

• Understand your enrollment windows

• Review your plan annually

• Consider additional coverage based on your needs
