What Is Not Covered by Medicare Part B
Part B covers outpatient medical care, but it leaves out dental, vision, hearing, long-term care, and most costs outside the country.
The gaps in Part B
Part B pays for outpatient care, doctor visits, and medical equipment, but it was never built to cover everything. Routine dental work, eye exams for glasses, hearing aids, and long-term custodial care all fall outside it. So does most care you get outside the United States.
This isn't a short list of exceptions. It's a different category of care that Medicare Part B simply doesn't touch, which is why so many people end up looking at a separate dental plan, a vision plan, or a Medicare Advantage plan that bundles some of this back in.
Whether you have other coverage filling the gap
Some people already have coverage that fills in what Part B leaves out. A retiree health plan from a former employer, a Medicare Advantage plan, or a standalone dental and vision policy can cover some of the costs Part B won't touch.
If you don't have anything else, the gap is real and immediate. A hearing aid, a set of dentures, or a stay in a nursing home can cost far more out of pocket than most people expect when they assume Medicare has them covered.
Check what you already have before you assume you need something new. If you're on a Medicare Advantage plan, ask what dental, vision, and hearing benefits are actually included, because they vary a lot from plan to plan.
If you have no supplemental coverage at all, it's worth deciding now, before you need the care, rather than after a bill arrives.
What people assume Medicare covers but doesn't
Long-term care is the big one. People hear Medicare and assume it will pay if they ever need a nursing home or long-term help at home. Part B doesn't cover custodial care, meaning help with daily activities like bathing or dressing, even over an extended stay.
Routine foot care, cosmetic surgery, and most prescription drugs also fall outside Part B. Drug coverage is handled separately, through a different part of Medicare or a private plan, so Part B alone won't cover what you pick up at the pharmacy.
Travel is another one people miss. If you're outside the United States and need care, Part B generally won't pay for it, which matters if you travel often or spend part of the year elsewhere.
The pattern across all of these is the same: Part B covers medical treatment, not the broader costs of aging or daily living. Knowing that distinction early helps you plan for the costs it won't touch.
Questions people ask about this
Does Medicare Part B cover dental implants?
No, dental implants and most other dental work fall outside Part B. Some Medicare Advantage plans include dental benefits, so it's worth checking a specific plan's coverage if this matters to you.
Does Medicare cover hearing aids?
Original Medicare, including Part B, doesn't cover hearing aids or the exams to fit them. Some Medicare Advantage plans offer hearing benefits, so this is another case where the plan details matter more than Original Medicare.
What pays for long-term nursing home care if Medicare doesn't?
Medicaid, long-term care insurance, or personal savings typically cover custodial care that Part B won't. Medicaid eligibility depends on income and assets and is run by the state, so check your state's rules if this is a concern.
Is Medicare Advantage better than Original Medicare for these gaps?
It depends on the specific plan, since Medicare Advantage plans vary widely in what extra benefits they include. Compare a plan's dental, vision, and hearing coverage directly rather than assuming Advantage plans all cover the same things.
Do I need a separate dental and vision plan if I have Medicare?
If you want routine dental and vision care covered, you likely need something beyond Original Medicare, since Part B doesn't include either. A standalone dental and vision plan or a Medicare Advantage plan with those benefits are the two common ways people fill this gap.
See what a Medicare Advantage or supplemental plan in your area actually covers before you assume you're protected.
Pull out your current Medicare paperwork and check whether you have anything beyond Part B, such as a Medicare Advantage plan or a retiree health plan. If you don't, think about which gaps matter most to you, dental, vision, hearing, or long-term care, since no single plan covers all of them equally well. Call your plan or your former employer's benefits office and ask directly what's included, rather than assuming. If you're considering a dental or vision plan, compare a few options before enrolling anywhere. Do this before you need the care, since enrollment windows and waiting periods can limit your options once a need comes up.
