The Parts of Your Health that Medicare Doesn’t Cover - And How People Fill Them In

The Parts of Your Health Medicare Doesn't Cover — And How People Fill Them In

Medicare covers an enormous amount — hospital stays, doctor visits, most prescription drugs through Part D, and more. But there's a short list of everyday health needs it was never designed to cover, and it tends to catch people off guard right when they need it most. Here's what's actually excluded, and the common ways people handle each gap.

Dental Care

Original Medicare doesn't cover routine dental work — cleanings, fillings, extractions, or dentures are all out of pocket. There's one narrow exception: dental care tied directly to a covered medical procedure, such as an exam required before heart valve surgery or an organ transplant, or extractions needed before radiation treatment for jaw cancer. Routine care doesn't qualify.

How people cover it: a Medicare Advantage plan that includes a dental allowance, a standalone dental insurance policy, a dental discount plan, or care through a dental school or community health center, which often charge reduced rates.

Vision Care

Part B covers a few specific, medically driven services: an annual glaucoma screening if you're considered high-risk, an annual diabetic retinopathy exam if you have diabetes, and cataract surgery, which includes one pair of glasses or contact lenses afterward. Routine eye exams for glasses, and the glasses or contacts themselves, aren't covered outside of that.

How people cover it: Medicare Advantage vision allowances, a standalone vision insurance plan, or community vision clinics.

Hearing Care

Medicare covers a diagnostic hearing or balance exam only when a doctor orders it to investigate a specific medical condition — not a routine hearing check. Hearing aids and the fitting exams that go with them aren't covered at all.

How people cover it: a Medicare Advantage hearing benefit, a standalone hearing insurance plan, or since 2022, FDA-approved over-the-counter hearing aids — a lower-cost option for mild-to-moderate hearing loss that doesn't require a prescription or exam to purchase.

Long-Term Custodial Care

This is the gap with the biggest financial consequences, and the most misunderstood. Medicare does cover skilled nursing care — but only short-term, only after a qualifying hospital stay (typically an inpatient stay of at least three days), and only up to 100 days, with a daily coinsurance kicking in after day 20. It's meant for rehabilitation, not ongoing care.

What it doesn't cover is what most people actually mean by "long-term care": ongoing help with daily activities like bathing, dressing, or eating, whether at home or in a nursing facility, for months or years at a time.

How people cover it:

•        Long-term care insurance, typically purchased well before it's needed

•        Medicaid, for those who financially qualify — usually after a personal spend-down of assets

•        PACE (Program of All-Inclusive Care for the Elderly), for eligible seniors who need nursing-home-level care but want to remain at home

•        Family caregiving and personal savings, which is where a large share of long-term care in the U.S. actually comes from

Care Received Outside the U.S.

Original Medicare generally doesn't cover health care received outside the United States, with only a few narrow exceptions (such as an emergency where a foreign hospital is genuinely closer than the nearest U.S. one).

How people cover it: certain Medicare Supplement (Medigap) plans include a foreign travel emergency benefit, generally covering 80% of emergency care abroad after a small deductible, up to a lifetime limit. Travel insurance is another option worth considering for extended trips.

A Few Other Gaps Worth Knowing

•        Cosmetic surgery isn't covered, except when needed to repair damage from an accident or to improve function following a deformity.

•        Acupuncture is covered only for chronic low back pain, and only up to a capped number of visits per year — not for other conditions.

•        Most massage therapy and alternative medicine falls outside what Medicare pays for.

One Thing Worth Knowing About Medicare Advantage's Extra Benefits

Many Medicare Advantage plans advertise dental, vision, and hearing coverage as a selling point, and for a lot of people that's a genuine reason to consider one. But the size and structure of these benefits is up to each insurer, within CMS's rules — one plan's "dental included" might mean two cleanings a year, while another's covers major work like crowns or dentures. These allowances can also change from one plan year to the next. It's worth reading the actual covered services and dollar limits rather than assuming a plan's dental, vision, or hearing benefit matches what you had elsewhere.

Putting It Together

No single option covers every gap on this list, and that's normal — most people end up combining a couple of these based on what matters most for their own health and budget. Revisiting your coverage each year, the same way you'd review your Medicare Advantage or Part D plan during the fall enrollment period, is a good moment to ask whether your current combination still fits, or whether a gap has opened up somewhere you didn't expect.
