Medicare, dental, vision, and hearing
Last reviewed June 11, 20263 min readBy the Goodsurance editorial team Reviewed by the Goodsurance editorial team
This is one of the biggest surprises new enrollees run into, because it runs against common sense. You finally have health coverage built for older adults, the exact group most likely to need glasses, hearing aids, and dental work, and routine versions of all three are the things Original Medicare leaves out. Understanding the gap precisely, including the medically necessary exceptions that do get covered, is what lets you plan for it instead of being caught off guard.
1What Original Medicare leaves out
Original Medicare (Part A and Part B) does not pay for routine dental care, routine eye exams for glasses, eyeglasses or contacts in most cases, routine hearing exams, or hearing aids. These are not oversights you can appeal; they are written into what the program covers. So the cleaning, the cavity, the new glasses, and the hearing aids are, by default, your cost.
That default is exactly why so many Medicare Advantage plans advertise these benefits so loudly: they are filling a real and well-known gap, and it is one of the main reasons people choose that path.
2The medically necessary exceptions
The blanket statement "Medicare does not cover dental, vision, or hearing" is not quite complete, and the exceptions matter because they are the expensive ones. Medicare covers care in these areas when it is medically necessary rather than routine:
- Vision: Medicare covers cataract surgery and, after it, a basic pair of corrective lenses, plus certain medical eye care such as treatment for glaucoma or macular degeneration. What it does not cover is the routine refraction exam to update your glasses prescription.
- Dental: Medicare generally excludes routine dental, but it covers dental services that are an integral part of a covered procedure. This area has been widening in recent years, so the current rule is worth checking.
- Hearing: Medicare covers diagnostic hearing and balance exams when a doctor orders them to diagnose a medical problem, even though it does not cover routine hearing tests or the aids themselves.
The line throughout is medical necessity. If the care is treating a diagnosed problem, Medicare often pays; if it is routine maintenance, it usually does not.
| Routine | Medically necessary | |
|---|---|---|
| Vision | ✗ | Cataract surgery + one pair of lenses |
| Dental | ✗ | Tied to a covered procedure |
| Hearing | ✗ | Doctor-ordered diagnostic exams |

3The ways people fill the gap
There is no single right answer here; these are trade-offs, not a ranked list with a winner. A Medicare Advantage plan bundles some dental, vision, and hearing, but the extras live inside the plan's networks and the specific allowance varies a great deal from plan to plan, the brochure number is a cap, not unlimited coverage. A standalone dental or dental-vision-hearing plan keeps your medical and dental coverage independent and lets you choose a benefit level, at the cost of a separate premium and often waiting periods. Paying out of pocket, deliberately, can be simpler for someone with low routine needs, with the trade-off of exposure if a big need appears.
- Most MA plans bundle some DVH
- Inside the plan network; an annual cap
- Buy dental or DVH separately
- A separate premium; often waiting periods
- Simplest for low routine needs
- Exposure if a big need appears
4The benefit that gets oversold: hearing aids
Hearing aids deserve a specific caution because they are expensive and because the benefit is the one most easily misread. When a plan advertises a hearing-aid benefit, it is typically an allowance applied toward the cost through specific providers, not blanket coverage of any device you choose. That can still be real, useful money, but it is worth knowing the shape of it before you choose a plan primarily for that reason. The same caution applies to high-end dental work: an annual allowance can be used up quickly by a single major procedure.
The dental, vision, or hearing number on a plan brochure is an annual ceiling, not unlimited coverage. One major procedure, or a pair of hearing aids, can use the whole year's allowance. Read the specific plan's benefit, not the category.
Common questions about Medicare
Quick answers to common questions
Tap any question to expand. Each question links to a fuller standalone answer.
Does Medicare cover hearing aids?
Original Medicare does not cover hearing aids or the exams used to fit them.
Some Medicare Advantage plans include a hearing benefit, but coverage varies by plan.
Does Medicare pay for hearing aids
Original Medicare does not cover hearing aids or fittings.
Some Medicare Advantage plans may include a hearing benefit, but what they cover varies by plan.
Does Medicare cover vision care?
Mostly no for routine care.
In 2026, Original Medicare does not cover routine eye exams for glasses or contact lenses, and it does not pay for the glasses or contacts themselves. It does cover some medical eye care: yearly glaucoma screenings for people at high risk, diabetic retinopathy exams, treatment for eye diseases, and cataract surgery (including one pair of standard glasses or contacts afterward). For those covered services you pay 20% after the $283 Part B deductible. Many Medicare Advantage plans add a routine vision benefit covering eye exams and an allowance for glasses.
Does Medicare cover skilled nursing facility care?
Yes, on a short-term basis.
Medicare Part A covers skilled nursing facility (SNF) care after a qualifying inpatient hospital stay of at least 3 days, when you need daily skilled care like nursing or therapy. In 2026 you pay $0 for days 1 through 20 of each benefit period, $217 per day for days 21 through 100, and all costs after day 100. Coverage is for skilled care while you recover, not for long-term or custodial care (help with daily activities like bathing or dressing), which Medicare does not cover. Long-term nursing home care is generally paid through Medicaid or private funds.
Does Medicare cover home health care?
Yes, when you qualify.
Medicare Parts A and B cover home health care if a doctor certifies that you are homebound (leaving home takes a major effort) and need part-time skilled care, such as skilled nursing, physical therapy, occupational therapy, or speech therapy. A Medicare-certified home health agency must provide the care under a plan your doctor reviews. You pay $0 for covered home health visits in 2026, and 20% for any durable medical equipment. Medicare does not cover 24-hour home care, meal delivery, or homemaker services like cleaning when that is the only care you need.
Is Medicare free?
No, Medicare is not free for most people in 2026.
Many people pay nothing for Part A (the part that covers hospital stays) because they paid Medicare taxes while working, but Part B (the part that covers doctor visits and outpatient care) has a standard premium, meaning a monthly amount you pay, of $202.90 in 2026. Part B also has a yearly deductible, the amount you pay before Medicare starts to share costs, of $283 in 2026. If you choose drug coverage under Part D, that has its own premium too. So while one part may cost you nothing, Medicare overall carries monthly premiums and out-of-pocket costs for most people.
What are the parts of Medicare?
Medicare has four parts, labeled A, B, C, and D.
Part A covers inpatient hospital stays, skilled nursing care, and some home health care. Part B covers doctor visits, outpatient care, preventive services, and durable medical equipment. Together, Part A and Part B are called Original Medicare. Part C, also called Medicare Advantage, is a way to get your Part A and Part B benefits bundled through a private plan, often with extra benefits. Part D covers prescription drugs. You can keep Original Medicare and add a separate Part D drug plan, or you can choose a Part C plan that may include drug coverage. Each path has different costs and rules.
Do I have to sign up for Medicare?
Not always, but many people are enrolled automatically.
If you are already getting Social Security benefits when you turn 65, you are usually enrolled in Part A (hospital coverage) and Part B (doctor and outpatient coverage) automatically. If you are not yet getting Social Security, you generally need to sign up yourself during your Initial Enrollment Period, the seven-month window around your 65th birthday. Signing up is not always required, since some people delay Part B if they have qualifying coverage from a current employer. But if you wait without qualifying coverage, you may owe a late enrollment penalty, an amount added to your premium for as long as you have it. Whether you must enroll depends on your current coverage and your situation.
At what age do you qualify for Medicare?
Most people qualify for Medicare at age 65.
You become eligible the month you turn 65, and your Initial Enrollment Period, the seven-month window for signing up, starts three months before your birthday month and ends three months after. Some people qualify before 65: if you have received Social Security disability benefits for 24 months, or if you have certain conditions such as end-stage kidney disease or ALS, you may become eligible earlier. Age 65 is the standard milestone, but a qualifying disability can open the door sooner.
What is the difference between Medicare and Medicaid?
Medicare and Medicaid are two different programs that are easy to confuse.
Medicare is a federal health insurance program based mainly on age, covering people 65 and older and some younger people with disabilities, regardless of income. Medicaid is a joint federal and state program based on income and need, helping people with limited income and resources pay for care. The names sound alike, but the qualifying rules are different: Medicare looks at your age or disability, while Medicaid looks at your income. Some people qualify for both programs at the same time, which is called being dually eligible, and the two can work together to cover costs.
What does Medicare Part A cover?
Medicare Part A covers inpatient hospital care, meaning care you get when you are formally admitted to a hospital.
It also covers skilled nursing facility care after a qualifying hospital stay, some home health care, and hospice care for people who are terminally ill. Part A is the hospital side of Original Medicare. It does not cover routine doctor visits or outpatient services; those fall under Part B. Part A also does not cover long-term custodial care, meaning help with daily activities like bathing or dressing when that is the only care you need. For inpatient stays, you pay an inpatient deductible of $1,736 per benefit period in 2026 before Part A begins covering your share.
Does Original Medicare have an out-of-pocket cap?
No, Original Medicare does not have a yearly out-of-pocket cap.
With Part A (hospital coverage) and Part B (doctor and outpatient coverage), there is no limit on the total amount you could pay in coinsurance, your share of costs after the deductible, in a single year. This is one of the most important things to understand about Original Medicare. To help manage this, many people add a Medigap policy, also called Medicare Supplement Insurance, which is private coverage that helps pay some of the costs Original Medicare leaves to you. Medicare Advantage plans, the bundled private option, do include a yearly out-of-pocket limit. The lack of a built-in cap is a key reason people consider extra coverage.
