What Does Medicare Not Cover?

Medicare is a federal health insurance program for people 65 and older, as well as certain younger people with disabilities. It is a solid foundation, but it was never designed to cover everything. If you go into retirement assuming Medicare handles all your medical costs, you are likely to be surprised by some large out-of-pocket bills.

The short answer to what Medicare does not cover falls into several clear categories: routine dental, vision, and hearing care; long-term custodial care; most care outside the United States; and a handful of other services people commonly assume are included. Let me walk through each one so you know exactly where the holes are.

Dental, Vision, and Hearing Care

This is the big one that shocks most new Medicare enrollees. Original Medicare (Parts A and B) does not cover routine dental exams, cleanings, fillings, crowns, dentures, or extractions. It does not pay for routine eye exams, eyeglasses, or contact lenses. It also does not cover hearing exams or hearing aids.

Think about how often you visit a dentist or optometrist. Now imagine paying for all of that completely out of pocket in retirement, when you are on a fixed income. That is the reality for many Medicare beneficiaries who do not plan ahead.

Some Medicare Advantage (Part C) plans do bundle dental, vision, and hearing benefits, which is one reason those plans attract a lot of attention. However, the coverage limits can be modest, and not every plan in every area includes meaningful benefits. You need to read the details before assuming you are covered.

Long-Term Care and Custodial Care

Medicare does not pay for long-term custodial care, which is the kind of help people need when they can no longer perform basic daily activities on their own, like bathing, dressing, or eating. This type of care is provided in nursing homes, assisted living facilities, and increasingly in private homes through home health aides.

Medicare will pay for short-term skilled nursing facility care after a qualifying hospital stay, but that benefit has strict rules and time limits. It is not the same as long-term care. Once the skilled care requirement ends, Medicare stops paying, and the daily rate for a nursing home can exceed $300 or $400 depending on where you live.

Long-term care is one of the biggest financial risks in retirement, and it is almost entirely uncovered by Medicare. Planning options include long-term care insurance, hybrid life insurance policies with long-term care riders, and certain annuity products that can help fund those costs.

Medical Care Outside the United States

If you travel internationally or spend part of the year abroad, this gap matters to you. Original Medicare generally does not cover health care services received outside the United States. There are very limited exceptions, such as certain emergencies near the Canadian or Mexican border, but they are narrow.

If you get sick or injured in another country, you will be paying out of pocket unless you have a separate travel health insurance policy or a Medigap plan that includes foreign travel emergency coverage. Some Medigap policies do include an emergency foreign travel benefit, so this is worth comparing if you are an active traveler.

Other Gaps People Commonly Miss

Beyond the big three above, there are several other services that Medicare either does not cover or covers in a very limited way:

  • Cosmetic surgery -- Medicare does not pay for procedures that are purely cosmetic, though it may cover reconstructive surgery that is medically necessary.
  • Acupuncture -- Medicare does cover acupuncture for chronic low back pain in certain circumstances, but coverage for other conditions is not included.
  • Routine foot care -- Trimming nails and other routine foot care is generally not covered, though some foot care related to diabetes complications may be.
  • Most chiropractic care -- Medicare only covers manual manipulation of the spine when medically necessary. It does not cover other chiropractic services.
  • Prescription drugs (without Part D) -- Original Medicare Parts A and B do not cover outpatient prescription drugs. You need to enroll in a Part D plan or choose a Medicare Advantage plan that includes drug coverage to get that benefit.
  • Private-duty nursing -- Around-the-clock nursing care at home is not covered.
  • Personal comfort items -- Things like a private room or television in a hospital room are not covered.

Cost-Sharing Is Also a Gap

It is worth mentioning that even for services Medicare does cover, you are still responsible for deductibles, copayments, and coinsurance. Part A has a hospital deductible that resets per benefit period, not per year. Part B has an annual deductible and then requires you to pay 20 percent of the Medicare-approved amount for most services, with no out-of-pocket maximum.

That 20 percent with no cap is a real exposure. If you need surgery, chemotherapy, or extended outpatient treatment, 20 percent of a large bill can be a significant number. Medigap supplemental insurance (also called Medicare Supplement) is designed specifically to cover some or all of that cost-sharing, which is why many people buy it alongside Original Medicare.

How to Fill the Gaps

You have a few main tools for addressing what Medicare leaves out:

  • Medigap (Medicare Supplement) -- Covers cost-sharing gaps in Original Medicare. Does not add new benefits like dental or vision, but limits your exposure on covered services.
  • Medicare Advantage (Part C) -- An alternative to Original Medicare that often bundles Part D, dental, vision, and hearing. Trade-offs include network restrictions and prior authorization requirements.
  • Standalone Part D -- Adds prescription drug coverage if you stay in Original Medicare.
  • Dental and vision insurance -- Standalone policies that cover routine care Medicare excludes.
  • Long-term care insurance or hybrid life policies -- Address the custodial care gap, which is often the most financially dangerous one.
  • Fixed indexed annuities (FIAs) -- Can be structured to provide guaranteed income that helps fund gaps, including long-term care costs.

The right combination depends on your health, your budget, and how much risk you are comfortable carrying. There is no single answer that works for everyone.

The Bottom Line

Medicare is valuable coverage, but it leaves meaningful gaps that can become expensive problems if you are not prepared. Dental, vision, hearing, long-term custodial care, overseas medical care, and cost-sharing exposure are the ones that trip people up most often.
