Key Takeaways

• Your Medicare coverage might not be as complete as you think, especially when it comes to out-of-pocket costs, prescription drugs, and long-term care.

• Being proactive about reviewing your plan annually, understanding what’s excluded, and exploring coordination options with other coverage can help you avoid costly surprises.

Understanding Medicare’s Limitations in 2025

Medicare plays a vital role in your healthcare, but it isn’t designed to cover everything. In 2025, you might find that some essential services and costs aren’t fully covered. Many people assume that once they’re enrolled in Medicare, all their medical needs will be taken care of. Unfortunately, that’s not always the case.

If you rely solely on Original Medicare—Parts A and B—you might be surprised by the gaps in coverage, especially if you don’t have any supplemental insurance. Let’s explore the areas where your Medicare coverage might fall short and how you can prepare.

1. Out-of-Pocket Costs Can Add Up Quickly

Even though Medicare covers a wide range of services, it doesn’t cover 100% of them. You’re still responsible for deductibles, copayments, and coinsurance. In 2025, here’s what those costs look like:

• Part A deductible: $1,676 per benefit period

• Part A coinsurance: $419 per day (days 61-90), $838 per day (lifetime reserve days)

• Skilled nursing facility coinsurance: $209.50 per day (days 21-100)

• Part B deductible: $257 annually

• Part B coinsurance: 20% of approved charges, with no annual cap

Without additional coverage, these out-of-pocket expenses can become a financial burden—especially if you have a hospital stay or need frequent outpatient care.

2. Prescription Drug Costs May Still Be High

Medicare Part D helps with prescription drug costs, but it doesn’t eliminate them. While 2025 brings good news with a $2,000 annual out-of-pocket cap, you’re still responsible for:

• A deductible (up to $590)

• Copayments and coinsurance during the initial coverage phase

• Out-of-pocket costs up to the $2,000 cap, which still requires careful budgeting

Additionally, not all medications are covered. Each plan has a formulary, and if your drug isn’t on it, you may face high costs or need to request an exception.

3. Medicare Doesn’t Cover Long-Term Custodial Care

If you need help with daily activities—like bathing, dressing, or eating—due to aging, disability, or a chronic condition, Medicare doesn’t cover custodial care.

This includes:

• Assisted living facilities

• Long-term care in nursing homes

• In-home personal care (unless skilled care is involved)

The cost of long-term care can easily run into thousands of dollars per month. If you don’t plan ahead, you could face significant financial strain or be forced to rely on Medicaid after depleting your assets.

4. Dental, Vision, and Hearing Services Are Largely Excluded

Original Medicare does not cover routine dental, vision, or hearing care. That means you’re likely paying out of pocket for:

• Eye exams and prescription glasses

• Hearing aids and exams

• Cleanings, fillings, and other dental procedures

These services are important to your overall health, and ignoring them can lead to bigger problems down the line. Supplemental options may help, but without them, costs fall entirely on you.

5. Coverage for Foreign Travel Is Limited

If you’re planning to travel outside the U.S., it’s essential to know that Medicare generally does not cover medical services you receive abroad. Exceptions are rare and usually limited to emergency situations near the border.

This means you should consider additional travel insurance or a plan with emergency travel benefits. Without it, even a minor illness overseas could result in a major expense.

6. High-Income Surcharges Might Apply

In 2025, if your modified adjusted gross income (MAGI) from 2023 is above a certain threshold, you’ll pay more for Part B and Part D. These income-related monthly adjustment amounts (IRMAA) apply as follows:

• Individuals earning above $106,000

• Couples filing jointly earning above $212,000

If you’re subject to IRMAA, your monthly premiums can significantly increase. Understanding this early helps you prepare for the added financial burden.

7. Preventive Services Aren’t Always Fully Free

Medicare covers many preventive services, such as screenings and vaccines. However, some services might involve cost-sharing or be denied if not properly coded or deemed medically unnecessary. You could face a surprise bill even when you think you’re following preventive care recommendations.

It’s important to:

• Ask if a service is covered before receiving it

• Confirm whether your provider accepts Medicare assignment

• Understand the billing practices of your provider

8. Mental Health Coverage Has Gaps

Medicare covers outpatient mental health services, but there are limitations:

• You’ll owe 20% coinsurance for therapy sessions after meeting your Part B deductible

• There may be restrictions on how often you can receive services

• Finding a provider who accepts Medicare can be challenging

Inpatient psychiatric care is covered under Part A but limited to 190 lifetime days in a freestanding psychiatric hospital. This cap doesn’t reset and may leave you without coverage if you need long-term inpatient care.

9. Coordination Between Plans Can Be Confusing

If you have other forms of insurance, such as retiree coverage or VA benefits, coordinating them with Medicare isn’t always straightforward. Problems can arise when:

• You assume one plan will cover a service, but neither does fully

• Providers bill the wrong plan first, causing delays or denials

• You miss deadlines for enrolling or switching coverage

Understanding how your plans interact helps prevent claim issues and unexpected costs. Reviewing your plan details regularly and seeking help when needed is key.

10. Annual Plan Changes Can Affect Your Benefits

Each year, Medicare plans can change:

• Covered drugs and formularies

• Premiums, deductibles, and copays

• Provider networks

• Coverage rules and limitations

If you don’t review your plan during the Medicare Open Enrollment Period (October 15 to December 7), you could be stuck with a plan that no longer fits your needs in the new year. Take time every fall to compare your current plan with available options.

What You Can Do to Stay Protected

You don’t have to accept these coverage gaps as a given. There are ways to strengthen your Medicare protection in 2025:

• Review your Medicare Summary Notice (MSN) or Explanation of Benefits (EOB) regularly to spot billing issues.

• Compare plans during Open Enrollment each fall to find one that meets your current medical needs.

• Consider supplemental coverage to help pay for costs Original Medicare doesn’t cover.

• Use preventive services to catch health issues early, potentially avoiding higher costs later.

• Create a long-term care plan that includes savings, insurance options, or family support strategies.

• Keep records of your income and understand how IRMAA could affect your premiums.

Being proactive and staying informed gives you more control over your healthcare and financial future.

Taking Action Before It’s Too Late

Waiting until a health crisis hits or you get a surprising bill can leave you scrambling for solutions. The best time to act is before any issues arise. Medicare’s complexity doesn’t have to overwhelm you—as long as you stay ahead of it.

Take the time to:

• Understand what’s covered and what’s not

• Ask questions about how services are billed

• Seek out resources and licensed experts to guide you

You’ve worked hard to earn your Medicare benefits. Make sure you’re getting the most out of them.

Make Informed Medicare Choices in 2025

In 2025, Medicare remains a crucial foundation for your healthcare—but it’s not a one-size-fits-all solution. Gaps in coverage, rising costs, and plan changes require your attention. By understanding these shortcomings and taking thoughtful steps, you can ensure your healthcare is as complete and cost-effective as possible.
