What Medicare Does Not Cover in 2026 — And What Fills Each Gap
Original Medicare (Parts A and B) generally does not cover routine dental care, vision exams and eyeglasses, hearing aids, long-term custodial care, or most medical care received outside the United States. Depending on the gap, Medicare Advantage plans, Medigap policies, standalone dental/vision/hearing plans, or long-term care insurance can help fill what Original Medicare leaves behind.
Key Facts
- Routine dental
- Not covered — no cleanings, fillings, dentures, or root canals unless tied to a covered medical procedure
- Hearing aids
- Not covered; costs vary widely and can run $1,000–$7,000+ per pair depending on technology
- Routine eye exams
- Not covered; eyeglasses and contacts are also excluded except after certain cataract surgeries
- Long-term custodial care
- Not covered — Medicare does not pay for ongoing help with daily activities at home or in a nursing home
- Care outside the U.S.
- Generally not covered; some Medigap plans cap foreign emergency coverage at a $50,000 lifetime limit
- No out-of-pocket maximum
- Original Medicare alone has no annual cap on what you owe — supplemental coverage is the only backstop
The Dental Gap
Original Medicare does not cover routine dental care — no cleanings, X-rays, fillings, extractions, root canals, or dentures. Medicare pays for dental work only when it is directly necessary for a covered medical procedure, such as jaw reconstruction after an accident or a dental clearance before heart surgery.
The result: most beneficiaries face the full cost of dental care out of pocket unless they have supplemental coverage. A single crown, implant, or partial denture can easily run into the thousands.
Vision: What's Covered and What Isn't
Original Medicare covers a medically necessary eye exam if you have diabetes (to screen for retinopathy) or if a doctor is checking for a disease like glaucoma. It does not cover a routine exam to update your glasses prescription, nor the glasses or contacts themselves.
One exception: after cataract surgery through Original Medicare, you're entitled to one pair of eyeglasses or contacts. Otherwise, vision correction is an out-of-pocket expense.
Hearing: A Costly Gap
Original Medicare does not cover routine hearing exams or hearing aids. A diagnostic hearing test ordered to evaluate a medical condition may be covered under Part B, but the hearing aid and fitting exam are excluded.
Hearing aids can range from roughly $1,000 to more than $7,000 per pair depending on technology. Over-the-counter hearing aids, authorized by the FDA in 2022, offer lower-cost options, but the coverage gap in Original Medicare remains.
The Real Cost of These Three Gaps
Together, dental, vision, and hearing gaps can add up to significant annual spending — many older adults face thousands of dollars per year in out-of-pocket costs for services Original Medicare won't pay for. Because Original Medicare has no annual out-of-pocket maximum, there's no ceiling on your combined exposure.
These aren't rare edge cases: most people over 65 need dental care yearly, hearing loss is common, and vision needs evolve with age. Planning for these costs is as important as planning for hospital deductibles.
The Long-Term Care Gap
Medicare does not pay for long-term custodial care — ongoing help with daily activities like bathing, dressing, and eating that many people eventually need. This differs from skilled nursing or rehab, which Medicare covers under strict, time-limited conditions after a qualifying hospital stay.
Skilled nursing facility care is only covered when you need skilled services after at least a three-day hospital inpatient stay, for up to 100 days, with substantial daily copayments after day 20. Once your care becomes primarily custodial, Medicare stops paying. Extended nursing-home or assisted-living stays — which can cost $50,000 to $100,000+ per year — are largely outside Medicare's scope, making long-term care insurance or Medicaid the main options.
Care Outside the United States
Original Medicare generally does not cover care in another country. If you need emergency treatment while traveling internationally, you're typically responsible for the full cost, with only narrow exceptions (care on a ship in U.S. waters, a foreign hospital closer than the nearest U.S. one, or care in Canada on a direct route between Alaska and another state).
For most international travel, short-term travel health insurance covers emergencies abroad more comprehensively than Medicare. Some Medigap plans also include a foreign travel emergency benefit.
How Medicare Advantage Closes Some Gaps
Medicare Advantage plans must cover everything Original Medicare covers, and many go further — the large majority of individual MA plans offer some dental, vision, or hearing benefit. Scope varies: some offer a modest annual dental allowance, others more comprehensive coverage, plus hearing-aid and routine-vision benefits.
MA plans also include an annual out-of-pocket maximum on Part A/B costs, which Original Medicare lacks — a financial backstop that matters in a serious-illness year. The trade-off: networks and prior authorization. Compare plans in your ZIP code during the Annual Enrollment Period (October 15 – December 7).
How Medigap Helps
Medigap policies wrap around Original Medicare, paying costs like deductibles, hospital copayments, and the 20% coinsurance you'd otherwise owe. They do not cover dental, vision, or hearing — those gaps remain regardless of which Medigap plan you choose.
Where Medigap helps internationally is a foreign travel emergency benefit in several plans (C, D, F, G, M, N): after a $250 deductible, they pay 80% of emergency care abroad up to a $50,000 lifetime cap. Medigap requires staying in Original Medicare rather than Medicare Advantage, so the two are an either/or choice.
Standalone Dental, Vision, and Hearing Plans
If you're in Original Medicare or an MA plan with limited extras, standalone dental, vision, and hearing plans are available in most states. Dental plans typically cover preventive care at 100% and share costs on basic and major services after a deductible and waiting period, usually with an annual benefit maximum of $1,000–$2,000.
Vision plans cover routine exams and an allowance toward glasses or contacts on a 12- or 24-month cycle. Hearing plans or discount programs reduce the cost of aids and fittings. Premiums and benefits vary by carrier and region — compare through Medicare's plan finder or a licensed agent in your area.

Does Medicare cover dentures or dental implants?
No. Original Medicare does not cover dentures or implants. Some Medicare Advantage plans include a dental benefit that may cover part of denture costs, but implants are often excluded even on Advantage plans. Check a specific plan's Evidence of Coverage for details.
Will Medicare pay if I have a medical emergency in Europe?
Generally no. Original Medicare does not cover care in Europe or most foreign countries. Some Medigap plans (C, D, F, G, M, N) cover 80% of emergency care abroad after a $250 deductible, up to a $50,000 lifetime maximum. For extended travel, a dedicated travel health policy provides broader protection.
Does Medicare cover any long-term care?
Medicare covers short-term skilled nursing (up to 100 days after a qualifying three-day hospital stay) and short-term skilled home health, but not ongoing custodial care (help with daily activities) in a nursing home, assisted living, or at home. Long-term care insurance, Medicaid (if you qualify), or savings are the main ways to cover extended care.
Can I get hearing aids through Medicare?
Not through Original Medicare, which excludes hearing aids and fitting exams. Some Medicare Advantage plans include a hearing benefit with an annual allowance. Over-the-counter hearing aids (available since 2022) are another lower-cost option.
Is Medigap or Medicare Advantage better for filling gaps?
It depends. Medicare Advantage often adds dental, vision, and hearing benefits and an out-of-pocket maximum. Medigap gives nationwide provider flexibility and lower cost-sharing on Part A/B services but doesn't fill dental/vision/hearing gaps. The right choice depends on your health, travel, doctors, and budget — a SHIP counselor can help you compare free.
