• Understanding what Medicare does and doesn’t cover can help you plan ahead, explore supplemental coverage, and avoid surprise medical bills.

Understanding Medicare’s Coverage Gaps

Medicare is a crucial program that provides healthcare coverage to millions of Americans, but it doesn’t cover everything. If you assume that Medicare will pay for all of your medical expenses, you may be in for an unpleasant surprise. From hospital stays to prescription drugs, certain costs could slip through the cracks, leaving you with unexpected bills. Knowing where these gaps exist can help you plan and protect your finances.

Even though Medicare was designed to provide financial relief to older adults and individuals with disabilities, it does not function as a comprehensive safety net. It is essential to understand that Medicare works on a cost-sharing basis, meaning that while it covers a portion of medical expenses, you will still have to cover some costs yourself. Without proper planning, you could be facing hefty bills for services that Medicare either doesn’t cover at all or only partially covers.

What Medicare Covers—and What It Doesn’t

Medicare is divided into several parts, each covering different types of healthcare services:

• Medicare Part A (Hospital Insurance): Covers inpatient hospital stays, skilled nursing facility care, hospice care, and some home health services.

• Medicare Part B (Medical Insurance): Covers outpatient care, doctor visits, preventive services, and medical supplies.

• Medicare Part D (Prescription Drug Coverage): Helps cover the cost of prescription medications.

While these parts cover a significant portion of healthcare costs, they don’t eliminate all expenses. Many services and treatments still require cost-sharing, and some aren’t covered at all.

Additionally, there are strict eligibility rules and conditions that apply to each type of coverage. For example, Medicare Part A may cover a hospital stay, but only if it is considered medically necessary and meets specific criteria. Similarly, Medicare Part B covers preventive screenings, but not all diagnostic tests or specialist visits may be included. These limitations mean that beneficiaries must be vigilant in understanding exactly what their plan includes and what they may have to pay out of pocket.

The Biggest Medicare Coverage Gaps You Should Know

1. High Out-of-Pocket Costs

Medicare requires you to pay deductibles, copayments, and coinsurance. In 2025, for example, the Part A hospital deductible is $1,676 per benefit period, while the Part B annual deductible is $257. Even after meeting these deductibles, you’ll still be responsible for 20% of the cost of most outpatient services under Part B.

This means that even routine medical visits or necessary treatments can add up over time. If you need frequent doctor visits, specialized treatments, or medical equipment, the 20% coinsurance can become a financial burden. Many people mistakenly assume that once they meet their deductible, Medicare will cover the rest, but that is not the case.

2. Limited Coverage for Long-Term Care

Many people assume that Medicare will cover nursing home care, but that’s not the case. Medicare only covers short-term stays in skilled nursing facilities under certain conditions. Long-term care, including custodial care in a nursing home or assisted living, is not covered. If you need ongoing care, you may have to pay out of pocket or look into alternative coverage options.

Long-term care is one of the most significant expenses that older adults face. A single year in a nursing home can cost tens of thousands of dollars, and with Medicare offering little to no assistance, many people turn to Medicaid or private long-term care insurance to fill the gap.

3. No Routine Dental, Vision, or Hearing Coverage

Original Medicare doesn’t cover routine dental care, eye exams for glasses, or hearing aids. That means if you need a root canal, new glasses, or a hearing test, you’ll likely have to pay for it yourself. This can lead to significant out-of-pocket expenses, especially as these needs become more common with age.

Since dental, vision, and hearing problems are prevalent among older adults, many Medicare beneficiaries find themselves spending thousands on services that Medicare does not cover. Preventive care in these areas is crucial, but without coverage, many people delay seeking treatment, which can lead to worsening health conditions.

4. Prescription Drug Costs Can Add Up

While Medicare Part D helps cover prescription drugs, it still comes with premiums, deductibles, and copayments. The maximum Part D deductible in 2025 is $590, and while the catastrophic phase eliminates additional out-of-pocket spending after reaching $2,000, costs leading up to that point can still be burdensome.

Additionally, different plans cover different drugs, and formularies change from year to year. If a medication you need is not on your plan’s formulary, you may have to pay the full cost, which could be substantial.

5. Overseas Medical Care Is Not Covered

If you travel outside the U.S., don’t expect Medicare to cover your medical bills. Original Medicare generally doesn’t provide coverage outside the country, except in very limited situations. If you plan on traveling internationally, you may need to consider supplemental coverage for peace of mind.

Strategies to Protect Yourself from Coverage Gaps

Understanding these gaps is the first step. The next step is figuring out how to manage them so you don’t get caught off guard by unexpected medical bills. Here’s what you can do:

1. Budget for Out-of-Pocket Costs

2. Consider Additional Coverage Options

3. Plan for Long-Term Care

4. Enroll in a Prescription Drug Plan Early

5. Check for Preventive Services
