What Does Medicare Not Cover in 2026?

The biggest thing Medicare does not cover is the one most families assume it does: long-term care, the day-to-day help a parent needs when they can't manage alone. That gap, plus routine dental, vision, and hearing, is where the surprise bills come from.

The gaps that catch families off guard

Most people picture Medicare as the thing that covers Mom or Dad once they hit 65, full stop. And for hospital stays, doctor visits, and short rehab, it largely does. The trouble starts with the care that isn't a hospital stay or a quick recovery, the steady, unglamorous help that adds up month after month. That's where Original Medicare (Parts A and B) draws a hard line: it excludes long-term custodial care, apart from hospice, most routine dental, vision, and hearing care, most care outside the United States, routine foot care, and cosmetic surgery.1

Long-term care: the costliest thing Medicare does not cover

Medicare does not cover long-term custodial care. That's the term for help with the activities of daily living, bathing, dressing, eating, getting to the bathroom, when that personal care is the only care a person needs. It doesn't matter whether that help happens in a nursing home, an assisted living community, or your own living room. If it's custodial, Medicare won't pay for it. The official long-term care page on Medicare.gov says so plainly.1 There is one exception, and it matters if your parent is terminally ill: the statute and regulations carve hospice out of the custodial-care exclusion, so the hands-on personal care needed for the palliation or management of a terminal illness is covered when it is furnished as part of Medicare hospice care.1

So where does the confusion come from? Medicare does pay for skilled nursing, just not the way people assume.

Skilled nursing is covered, but only short-term

Medicare Part A covers a stay in a skilled nursing facility, but only on a short-term, post-acute basis. To qualify, you generally need a hospital stay of at least three consecutive days as an admitted inpatient (the day you leave doesn't count), a doctor's decision that you need daily skilled care, and entry into a Medicare-certified facility, generally within 30 days of leaving the hospital, for skilled care tied to that stay. Original Medicare then covers up to 100 days per benefit period (a Medicare Advantage plan may charge copays in the first 20): days 1 through 20 at $0 a day once the $1,736 Part A deductible is paid, which the qualifying hospital stay normally covers. Days 21 through 100 carry a daily coinsurance of $217 in 2026, then coverage ends.5,6

That last part is the crux. Coverage stops at 100 days, and it only ever applied to skilled care, not to help with daily living. If your mother needs help getting dressed every morning indefinitely, that's custodial care, and Medicare was never going to cover it, hospital stay or not.

The three-day requirement itself is where families most often get told no, and it is not the dead end it looks like. First, know that time spent under observation or in the emergency room before you're admitted doesn't count toward the three days, even if you were there overnight.5 Then check all four ways around it:

• A waiver. You may not need the three-day minimum if your doctor participates in an Accountable Care Organization approved for a Skilled Nursing Facility 3-Day Rule Waiver, and a Medicare Advantage plan may also waive it.5
• Re-entry. If you leave a facility and re-enter the same or another one within 30 days, you don't need another three-day qualifying hospital stay. The same holds if skilled care stops while you're in the facility and then starts again within 30 days.5
• An appeal. A hospital's switch of your status from inpatient to observation may be appealable, on one of two tracks. For an admission on or after February 14, 2025, the track is open: ask for a fast appeal while you're still in the hospital. Going home doesn't by itself end your appeal rights, but act promptly and follow the instructions on your Medicare Change of Status Notice (CMS-10868), or contact your local BFCC-QIO if you can't find it.6 For an admission between January 1, 2009 and February 13, 2025, you also needed, among other conditions, observation services after the switch and either no Part B during the stay, or 3 or more hospital days but fewer than 3 as an inpatient and a skilled nursing facility admission within 30 days. That window closed on January 2, 2026, and a late request is denied unless you show good cause, such as serious illness, incapacity, a death in the immediate family, records lost to fire or disaster, or wrong information about how to appeal. If you qualify, file immediately and attach the reason.5
• Another payer. If none of it fits, ask whether the care can be delivered in another setting like home health, or whether Medicaid or veterans benefits can cover the facility stay instead.5

What about a nursing home or assisted living?

This is where the distinction bites. A "nursing home" can mean two very different things. A short rehab stay after a hip replacement? Medicare may cover that for a while, under the skilled-nursing rules above. A permanent room because someone can no longer live safely alone? That's long-term custodial care, and it's on you, your family, or one of the alternatives below.

Assisted living works the same way. Medicare doesn't pay the rent or the personal-care fees at an assisted living community, because the exclusion follows the care rather than the setting, and that fee buys custodial care.1 It might still cover a covered medical service a resident receives there, a doctor visit, a covered medication, and the hospice exception above still applies to a resident who elects hospice, but not the cost of living there.

Adult day care follows the same line. Original Medicare doesn't pay for adult day programs, the daytime supervision and custodial care many families use to keep a parent safe during working hours; Medicare's own long-term care page says Medicare doesn't pay for long-term care and lists adult day health care among what long-term care includes. Medicare.gov points families toward Medicaid, if they meet their state's rules, or private long-term care insurance instead.7 A few narrow channels can still help. Our guide to whether Medicare covers adult day care walks through each one.

Home care has the same catch

Plenty of families hope to keep a parent at home and lean on Medicare to help. It can, but narrowly. Medicare covers home health care only when someone is homebound and needs intermittent skilled care, skilled nursing or therapy, ordered by a doctor and delivered through a certified agency. For those covered services you generally pay $0. Durable medical equipment is the exception: Medicare pays 80% of the approved amount and you pay the other 20%, once you've met the Part B deductible.8

What it specifically won't cover, per Medicare's own home health rules: around-the-clock care at home, meals delivered to the house, homemaker services unrelated to the care plan, like cleaning and laundry, and custodial personal care when that personal care is the only thing needed.8

Read that last one carefully, because the word "only" is doing real work and families give up money here that is theirs to claim. While a Medicare-covered nurse or therapist is still visiting, the home health benefit also pays for a home health aide, and Medicare's own examples of that aide's job are help with walking, bathing or grooming, changing bed linens, and feeding.8 Those are the same hands-on tasks the exclusion names. So if a nurse or therapist is coming to the house, ask the agency for aide hours rather than assume Medicare pays nothing toward them. What Medicare won't fund is someone there for hours each day once the skilled care has ended and personal care is all that's left.8

Dental, vision, and hearing: what Medicare does not cover

Original Medicare covers almost none of the routine dental, vision, and hearing care families lean on, which catches many new enrollees off guard.1

Dental. Routine dental care isn't covered: cleanings, fillings, extractions, dentures, none of it. But dental work tied to serious medical treatment is a real exception. Medicare covers a dental or oral exam as part of the workup before, and the treatment needed to clear an oral or dental infection before or alongside, an organ transplant, a stem cell or bone marrow transplant, a cardiac valve replacement or valvuloplasty, or chemotherapy, CAR T-cell therapy, or high-dose bone-modifying drugs used to treat cancer. For head and neck cancer it covers the pre-treatment exam, infection treatment before or alongside the cancer treatment, and treatment of dental complications afterward. For dialysis for end-stage renal disease it covers the exam and the infection treatment, before or alongside dialysis. These are specific services, not dental care in general. So if your parent is heading into cancer treatment or starting dialysis, don't accept "Medicare doesn't cover dental" for the pre-treatment workup.1,3 CMS's manual adds that this may not include every service a dentist recommends: before a transplant or heart valve procedure, an infected tooth may be pulled, but an implant or crown may not count as immediately necessary, and then Medicare pays nothing for it.9 One more exception matters if your parent is frail or medically complex: when their underlying condition or the sheer severity of the dental procedure means it has to be done as an inpatient, Part A may pay for the hospital stay, though not for the dental work itself.1 When the dental work itself isn't covered, the doctors' services tied to it aren't either, including the anesthesiologist, even if the hospital stay is.10 Otherwise, the everyday dentist visit is out of pocket.

Vision. Original Medicare doesn't cover routine eye exams for glasses, the eyeglasses themselves, or contact lenses. It does cover medically necessary eye care, such as cataract surgery, a yearly glaucoma screening for people at high risk, and a yearly diabetic retinopathy exam for people with diabetes, but not the exam-and-frames trip most people mean by "the eye doctor."1,11 One exception is worth real money and gets missed constantly: Part B covers one pair of conventional eyeglasses with standard frames, or one set of conventional contact lenses, after each cataract surgery in which an intraocular lens is inserted. Two eyes done in two surgeries means a pair after each one, not one pair for life. You pay any extra for upgraded frames, and after the Part B deductible you generally pay 20% of the approved amount, and only a supplier that participates in Medicare can be paid for it.2

Hearing. Hearing aids aren't covered, and neither are the routine exams to fit them. Given what a pair of hearing aids runs, this one stings.1

So what fills these gaps? A few options:

• Medicare Advantage. Advantage plans (other than Medical Savings Account plans, which follow separate rules) are allowed to offer supplemental benefits in addition to Medicare-covered services, and that's the mechanism by which a plan can add dental, vision, or hearing coverage.1 Whether a particular plan offers them, and how much they actually pay, varies by plan, so read the specifics before you assume a plan covers what you need. Some of these are optional extras you choose to buy, so they can carry a premium of their own.1
• Low-cost dental care. With Medicare you generally can't buy a stand-alone dental plan through the Health Insurance Marketplace. Where HealthCare.gov runs it, you can't unless you're also buying a health plan, and it's illegal for someone who knows you have Medicare to sell you a Marketplace plan; a state-run Marketplace may offer one.12 Cheaper routes exist. Federally funded health centers must offer preventive dental care with fees based on ability to pay,13 dental school clinics charge reduced rates under licensed dentists' supervision,14 states may cover adult dental under full Medicaid,15 PACE covers what its care team decides a member needs,16 and some veterans get free VA dental care.17 Our affordable dental care guide covers who qualifies.
• Paying out of pocket and budgeting for it, which is where a lot of people end up.

Care abroad, foot care, and cosmetic surgery

Care outside the United States. Medicare usually doesn't cover health care you get while traveling outside the United States, and in most cases you pay all of the costs. For this purpose the 50 states, the District of Columbia, Puerto Rico, the U.S. Virgin Islands, Guam, the Northern Mariana Islands, and American Samoa all count as inside the U.S.18 Medicare names three narrow situations in which it may pay, in rare cases, for inpatient hospital, doctor, and ambulance services in a foreign country: you're in the U.S. when a medical emergency happens and the foreign hospital is closer than the nearest U.S. hospital that can treat you; you're traveling the most direct route through Canada between Alaska and another state, without unreasonable delay, when an emergency happens and the Canadian hospital is closer; or you live in the U.S. and a foreign hospital is closer to your home than the nearest U.S. hospital that can treat your condition, emergency or not.18 Outside those, don't count on Medicare overseas. If you travel a lot, look into travel medical coverage or a Medigap plan with a foreign-travel emergency benefit.

Routine foot care. Medicare doesn't cover routine foot care like nail trimming or callus removal for otherwise healthy feet. It does cover medically necessary foot care, such as treating a foot injury or disease, and even routine-looking care can be covered when diabetes or another systemic condition makes it risky for a non-professional, so this gap is narrower than it sounds.1,19

Cosmetic surgery. Purely cosmetic procedures aren't covered. The exception is narrower than the word “reconstructive” suggests: what's excepted is surgery required for the prompt repair of an accidental injury, or surgery to improve the functioning of a malformed body part.1

What to do about the long-term-care gap

The dental and vision gaps are an annoyance you can budget around. The long-term-care gap is the one that can run through a family's savings, so it's worth knowing the real options before you're in a crisis.

For long-term care specifically, there are four paths:

Private pay. Many families start here simply because it's the default, covering costs out of savings, a pension, or the sale of a home. It works until the money runs low, which, given what care costs, it often does.

Long-term care insurance. A policy bought ahead of time (usually well before you need it) can cover custodial care Medicare won't. The trade-off is that premiums aren't cheap, and you generally have to be in decent health to qualify when you apply, so it's something to look at earlier rather than later.

VA benefits. For veterans who qualify, VA benefits can help pay for long-term care Medicare won't. Under current law, through December 11, 2026, when that provision is set to end unless Congress extends it, the VA must provide nursing home care it determines is needed to a veteran who needs that care for a service-connected disability, and to a veteran who needs nursing home care and has a service-connected disability rated at 70 percent or more; separately, a veteran with any compensable service-connected rating is among those exempt from the VA's extended-care copayments.4 Other veterans may still qualify depending on income and level of care needed, and it's worth asking about the Aid and Attendance (A&A) pension, so check with the VA even if you assume you won't qualify.

Medicaid. This is the big one, and the most misunderstood. Unlike Medicare, Medicaid does cover long-term care, including nursing-home care and, in many states, in-home and assisted-living support, for people who meet the income and asset limits. Medicaid pays for the largest share of long-term care services, and whatever no public or private program covers, families pay themselves.20 The eligibility rules are strict and vary by state, but for families facing years of custodial care, Medicaid is often where the road leads.1
