This Covered Medicare Benefit Could Help Lower Your Medical Bills

You might assume you should only tap into your Medicare insurance when something goes wrong with your health. But Medicare doesn't just cover you when you're already sick or injured. What many Americans may not realize is that Medicare Part B covers preventive services designed to reduce the risk of certain illnesses or detect health problems early. By accessing preventive care like vaccines and screening tests, you won't just be helping your health — you could be helping your wallet with lower medical bills.

Health care is one of retirees' biggest expenses, with a 2026 Fidelity study estimating that a 65-year-old retiring that year could spend an average of $185,500 on medical costs throughout retirement. Preventive services may help beneficiaries avoid some future medical expenses by reducing the risk of certain illnesses or identifying health problems before they become more serious. In 2026, the standard Medicare Part B premium is $202.90 per month, although higher-income beneficiaries can pay as much as $689.90. While these costs can add up — starting around $2,434.80 per year — they're a fraction of what you would pay for a serious illness like heart disease, stroke, cancer, or diabetes that went unchecked.

In fact, the CDC reports that chronic diseases are a major driver of illness and health care spending in the U.S., creating substantial costs even for people with insurance coverage. For example, while Medicare covers chemotherapy, you'll still typically be required to pay about 20% for in-clinic treatment. Since some chemo treatments can exceed $10,000 per month, that's potentially $2,000 per month out of pocket.

To receive most preventive services without out-of-pocket costs under Original Medicare, you'll need to make sure your health care provider accepts Medicare assignment. Otherwise, you may have to pay the full amount upfront. Some providers may opt out of Medicare altogether, in which case Medicare generally won't cover their services, even if the treatment would normally qualify for coverage. Always check before booking any medical services whether the provider accepts assignment with Medicare, to avoid unexpected bills and lower your Medicare costs.

Medicare-covered preventive services include yearly wellness visits; flu and hepatitis B vaccines; screenings for conditions such as osteoporosis, glaucoma, cancer, diabetes, and high cholesterol; counseling for alcohol misuse, obesity, and smoking; and depression screenings and cognitive assessments. Some services may require you to be identified as high risk but otherwise, you won't pay for most of these preventive services so long as you're enrolled in Medicare Part B or C (Medicare Advantage) and your provider accepts Medicare assignment or is in your plan's network. Keep in mind that your annual wellness visit isn't the same as a routine physical, and additional tests or treatments performed during the appointment may result in charges.

However, Original Medicare has limited coverage for routine dental, vision, and hearing care. Medicare Advantage plans may offer additional benefits in these areas, or you can explore separate coverage options. While preventive services won't guarantee you never get sick or injured, they can help to reduce the risk of a chronic illness being one of the health care costs that sneak up on you in retirement.
