We talk to people every day who are excited about Medicare, and rightly so — but there's a common misconception that it covers everything. Here are five real gaps in Original Medicare, plus a distinction that trips up almost everyone.
The short version
Original Medicare is excellent at what it's designed for — hospital stays, doctor visits, and medically necessary care — but it leaves real gaps most people don't expect. Routine dental care, routine vision care, hearing aids, long-term custodial care, and most care received outside the U.S. are all generally excluded. On top of that, there's a commonly confused distinction between the Annual Wellness Visit Medicare does cover and a traditional physical exam, which it generally doesn't. Understanding these gaps before you need the services is what actually lets you plan for them, whether through a Medicare Advantage plan, Medigap, standalone dental and vision coverage, or long-term care insurance.

Routine dental care (and most dentures)
Your yearly cleaning, fillings, extractions, and most dentures are generally not covered by Original Medicare. While there are a few very specific, medically necessary dental procedures that Medicare might cover, such as an exam before an organ transplant or certain cancer treatments, the vast majority of routine dental work falls outside this scope. This can quickly become a significant expense as dental needs tend to increase with age, and most dentures specifically are not covered by Original Medicare, so you'll pay out of pocket for this type of care.
Routine eye exams, eyeglasses, and contact lenses
If you're looking to get your eyes checked for a new glasses or contacts prescription, Original Medicare won't pick up the tab. While it does cover medically necessary eye care, such as for cataracts or glaucoma, routine vision services are excluded. That means the cost of new frames and lenses will likely be your responsibility.
Hearing aids and routine hearing exams
The cost of hearing aids can be substantial, and unfortunately, Original Medicare does not cover routine hearing exams, fittings, or the hearing aids themselves. This lack of coverage often presents a significant financial burden for many seniors who experience hearing loss, a common age-related condition.
While Medicare Part B may cover diagnostic hearing and balance exams if your doctor orders them to determine the need for medical treatment, it does not extend to the purchase or maintenance of hearing aids. As a result, beneficiaries frequently face considerable out-of-pocket expenses to obtain these essential devices.
To mitigate these costs, some individuals explore alternative coverage options such as Medicare Advantage plans, which often include hearing benefits, or separate supplemental insurance policies specifically designed to cover hearing-related services and devices. Understanding these limitations and planning accordingly is crucial for maintaining quality of life and effective communication as hearing health declines with age.
Long-term custodial care
This is perhaps one of the biggest misunderstandings about Medicare, and it's an important one. While Medicare Part A does cover short-term skilled nursing facility care, such as rehabilitation after a hospital stay, up to 100 days under specific conditions, it generally does not cover long-term custodial care. This includes day-to-day assistance with activities like bathing, dressing, eating, or using the restroom, whether that care is provided in a nursing home, an assisted living facility, or even in your own home. Long-term care costs can be substantial, and without proper planning, they can quickly deplete savings and financial legacy.
Most care while traveling outside the U.S.
Dreaming of international travel in retirement? Just be aware that Original Medicare typically doesn't cover healthcare services you receive while traveling outside the United States. There are a few very limited exceptions for emergencies in Canada or Mexico, or on a ship in U.S. territorial waters. But for most international adventures, you'll want to look into travel insurance or a Medicare Advantage plan that offers out-of-country coverage.
The key distinction: Annual Wellness Visit vs. routine physical exam
This is a point that causes a lot of confusion. While Medicare does cover an Annual Wellness Visit (AWV) once every 12 months, after your first 12 months with Part B, this is not the same as a comprehensive annual physical exam that many people are used to getting.
Here's the key distinction, and why it matters for your wallet:
- Medicare Annual Wellness Visit (AWV): this visit is all about prevention and planning for your health. Your doctor will primarily review your medical and family history, discuss your health risks, help you create or update a personalized prevention plan, and perform basic measurements like height, weight, and blood pressure. They might also screen for cognitive impairment and discuss advance care planning. The important part: an AWV typically does not include a hands-on physical exam, blood work, or other diagnostic tests unless there's a specific medical necessity, which would then be billed separately.
- Routine annual physical exam: this is the more traditional, hands-on head-to-toe examination by your doctor. It usually involves a physical assessment, such as listening to your heart and lungs, palpating your abdomen, and checking reflexes, and often includes blood work or other lab tests. Original Medicare generally does not cover a routine annual physical exam. If you receive one, you'll likely be responsible for the full cost.
It's absolutely vital to understand this difference to avoid unexpected bills. If your doctor performs additional services during your Annual Wellness Visit that go beyond the scope of preventive planning, for example addressing a new health concern or ordering specific tests, those services will likely be billed separately, and you may owe a deductible or coinsurance. Always ask your doctor's office how services will be billed before your appointment.
This confusion is common enough that it's worth repeating in slightly different words: the Annual Wellness Visit exists to build and update a prevention plan, not to replace the comprehensive physical exam many people grew up expecting from an annual doctor visit. If you walk into an appointment assuming the two are interchangeable, you may leave having received exactly the visit Medicare intended, while still being surprised by a bill for anything beyond that scope. Confirming which type of visit is being scheduled, by name, before you go in, is the simplest way to avoid that mismatch entirely.
What are your options to fill these gaps?
While Original Medicare is a cornerstone of retirement healthcare, understanding its limitations is crucial for smart planning. To help cover these uncovered services and reduce out-of-pocket costs, many people consider:
- Medicare Advantage Plans (Part C): these plans are offered by private insurance companies approved by Medicare and often include valuable extra benefits like dental, vision, and hearing coverage, as well as prescription drug coverage (Part D). Some Medicare Advantage plans may even cover a traditional annual physical exam. They also come with an annual out-of-pocket limit, which Original Medicare alone doesn't have.
- Medicare Supplement Insurance (Medigap): these plans work with Original Medicare and help pay for some of the costs Original Medicare doesn't cover, such as deductibles, copayments, and coinsurance. It's important to remember that Medigap plans generally don't cover the routine services listed above, like routine dental, vision, hearing aids, or long-term care.
- Standalone dental, vision, or hearing plans: you can purchase separate insurance policies specifically for these services, which can be a good way to get targeted coverage for your specific needs.
- Long-term care insurance: for the potentially substantial costs of long-term custodial care, a separate long-term care insurance policy is often the primary way to gain coverage and protect your savings.
A quick checklist
- Review whether your specific dental, vision, and hearing needs are likely to be routine maintenance or medically necessary treatment, since the coverage rules differ.
- Ask whether your next doctor visit will be billed as an Annual Wellness Visit or a full physical exam, and what that means for your bill.
- Confirm whether a Medicare Advantage plan available in your area includes the specific routine benefits you're most likely to use.
- If you're considering extended international travel, price out a separate travel insurance policy rather than assuming Medicare Advantage out-of-country benefits will be sufficient.
- Talk to a licensed Medicare advisor before a gap actually affects you, not after.
- Keep a simple written note of which plan type covers which gap for your household, since it's easy to lose track once you're juggling Original Medicare alongside a Medigap policy and one or two standalone plans.
