Medicare covers a lot — but what it doesn’t cover surprises millions of seniors every year. Routine dental work, hearing aids, eyeglasses, and long-term care can cost thousands of dollars that Medicare simply won’t touch. Knowing these gaps before you need care is the difference between financial stability and a devastating bill.
- Original Medicare does NOT cover routine dental, vision, or hearing aids
- Long-term care (nursing home, assisted living) is largely not covered
- Cosmetic procedures and acupuncture (with exceptions) are excluded
- Overseas medical care is generally not covered
- Medigap plans, Medicare Advantage, and standalone policies can fill these gaps
The 9 Biggest Medicare Coverage Gaps
1. Routine Dental Care
Original Medicare doesn’t cover routine dental exams, cleanings, fillings, crowns, dentures, or tooth extractions. This shocks most new enrollees — the average senior spends $1,600/year out of pocket on dental care. Some Medicare Advantage plans include dental benefits, making them worth comparing if dental care is a priority.
2. Vision and Eyeglasses
Medicare doesn’t cover routine eye exams, eyeglasses, or contact lenses. It WILL cover a diabetic eye exam and cataract surgery, but your everyday glasses remain your expense. Vision coverage is available through many Medicare Advantage plans or standalone vision policies.
3. Hearing Aids and Exams
Over 38% of Americans aged 65+ have hearing loss — and Original Medicare covers none of the cost of hearing aids, which average $4,600 per pair. Diagnostic hearing tests ordered by a doctor ARE covered, but the aids themselves are not. Again, many Medicare Advantage plans now include hearing aid benefits.
4. Long-Term Care (Nursing Home Beyond 100 Days)
This is the biggest gap of all. Medicare covers skilled nursing facility care for up to 100 days per benefit period after a qualifying 3-day hospital stay — but only the first 20 days are fully covered. Days 21–100 require a $200/day copay in 2025, and after day 100, you’re entirely on your own. Long-term care insurance or Medicaid are the main solutions.
5. Overseas Medical Care
If you travel outside the U.S., Medicare generally doesn’t cover your medical bills. There are a few narrow exceptions (e.g., a Canadian hospital that’s closer than a U.S. one), but for most international travel, you need separate travel health insurance. Medicare Supplement Plans C, D, F, G, M, and N all include 80% foreign emergency coverage after a deductible.
6. Cosmetic Surgery
Medicare doesn’t cover procedures done purely for cosmetic reasons. However, if a procedure has a medical purpose — like rhinoplasty to correct a breathing problem, or blepharoplasty that impairs vision — Medicare may cover it.
7. Most Acupuncture (Except for Low Back Pain)
Medicare added limited acupuncture coverage for chronic low back pain in 2020 — up to 12 sessions per year. All other acupuncture remains non-covered.
8. Foot Care for General Conditions
Routine foot care (nail trimming, callus treatment) is not covered unless you have a medical condition like diabetes. Diabetic patients may qualify for covered foot exams.
9. Prescription Drugs Under Part A and Part B
Outpatient prescription drugs are not covered by Parts A or B — you need Part D for that. Some drugs administered in a medical setting (like infusions) are covered under Part B, but your monthly medications are Part D territory.
How to Fill These Gaps
| Gap | Best Solution |
|---|---|
| Dental, Vision, Hearing | Medicare Advantage plan or standalone insurance |
| Long-term care | Long-term care insurance or Medicaid planning |
| 20% coinsurance gap | Medigap Plan G or N |
| International travel | Medigap plan or travel health insurance |
| Prescription drugs | Part D drug plan |

How long does Medicare pay for nursing home care?

Bottom Line
Original Medicare is designed for acute medical care — not the long-term, everyday health expenses seniors often need most. Understanding what’s not covered lets you plan ahead, shop for the right supplemental coverage, and avoid getting blindsided by a bill you didn’t see coming.
