Most people arriving at 65 assume Medicare has them covered. They’ve paid into the system for decades, watched their parents use it, and finally have the card. The part that doesn’t land until a bill shows up in the mailbox is that Medicare was never built to cover everything, and the gaps it leaves aren’t small.
Medicare Part A covers hospital stays, and Part B covers doctors’ services and outpatient care. That’s the foundation, and it’s a solid one. But there are entire categories of care that sit completely outside those walls, and some of them represent the largest costs a retiree will face.
The uncovered list includes routine dental, vision and hearing care, long-term nursing home care, and most international medical care. Congress has talked about closing these gaps for years. As of 2026, no legislation has passed to add routine dental coverage to Original Medicare, leaving all those exclusions in place.
These aren’t obscure fine print buried in the Medicare handbook. They’re structural, they’re predictable, and most of them have at least partial workarounds. But only if you know about them before you need the care.
Long-Term Care: The Expense That Can Drain Decades of Savings
The most financially devastating gap in Medicare isn’t a high deductible or a surprise copay. It’s the years-long cost of needing help with daily life, getting dressed, bathing, eating, getting out of a chair, and learning that Medicare pays nothing for it.
Medicare covers some skilled nursing services but not custodial care: the ongoing help with bathing, dressing, and other activities of daily living that becomes a permanent part of life for millions of older Americans. Skilled care means a nurse administering IV medication, or a physical therapist working to restore your mobility after surgery.
Custodial care means someone helping you get up in the morning. What Medicare does cover is short-term skilled nursing care for up to 100 days after a qualifying hospital stay. Once that skilled care need ends, Medicare stops paying. The moment care shifts to helping someone bathe, dress, eat, or manage daily activities, Medicare does not cover it.
According to SeniorLiving.org data, the median cost of a private room in a nursing home ranges from approximately $355 to $376 per day, depending on the survey, as of mid-2026.
Semiprivate rooms run lower, with national medians in the $315 to $328 per day range. That adds up to annual costs well into six figures for either room type. Assisted living runs lower but is still a serious number: national median costs for assisted living communities fall in the range of $6,200 to $6,313 per month as of mid-2026, varying by survey methodology and location.
The probability that you’ll need this care is higher than most people realize. According to the Urban Institute, 70% of adults who survive to age 65 develop severe long-term care needs before they die, and 20% will need care for more than five years.
Long-term care insurance is the most direct way to address this, and earlier is dramatically cheaper. Based on 2025 figures from the American Association for Long-Term Care Insurance, a 55-year-old man pays roughly $950 per year for a $165,000 policy with no inflation protection, or around $2,200 per year with 3% compound inflation protection. The same policy for a woman runs higher, reflecting that women statistically require longer periods of care.
Waiting until 65 to buy raises that man’s annual premium to $3,280 and the woman’s to $5,290. If you’re still contributing to a health savings account (HSA), those funds can legally pay long-term care insurance premiums, though they cannot be used to pay for the care itself.
Medicare Dental Coverage: The Routine Bill Nobody Plans For
A significant number of people turn 65 with an overdue dental issue and assume Medicare will handle it. Original Medicare does not cover routine dental care, including checkups, cleanings, X-rays, fillings, root canals, tooth extractions, and dentures. It hasn’t covered these things since Medicare launched in 1965, and as of 2026, Congress has again failed to add routine dental coverage to Original Medicare.
The American Dental Association reports that for seniors ages 65 and older, 33% have private dental benefits, 12% have public dental benefits, and 55% have no dental benefits at all, not counting Medicare Advantage plans. A majority of seniors over 65 have no dental coverage.
The bills this creates aren’t trivial: a single dental crown runs $1,000 to $1,700 in 2026. A full set of dentures costs $1,500 to $3,500 per arch. A dental implant runs $3,000 to $6,000.
Medicare will cover dental care only when it’s directly connected to a covered medical procedure, such as dental work required before heart valve surgery or treatment for a jaw fracture that requires hospitalization. For anything short of that threshold, you’re paying out of pocket.
Medicare Advantage does better here. According to KFF’s 2026 analysis, 98% of Medicare Advantage plans offer some dental benefits, with annual caps averaging around $1,500 per CMS data. Once that cap is reached, beneficiaries pay all remaining dental costs out of pocket until the next plan year resets.
A single crown can eat through an entire year’s allowance. If you’re on original Medicare only, the practical fix is adding a standalone dental plan before you need major work, ideally before your employer dental coverage ends, which avoids the waiting periods standalone plans typically impose on new enrollees.
Hearing Aids: $6,000 Out of Pocket, No Coverage in Sight
Hearing loss affects the majority of adults over 70, and the financial exposure it creates under Medicare is striking. Original Medicare does not cover services considered nonmedically necessary, and hearing aids fall squarely in that category. Not the devices, not the fitting, not the follow-up calibration appointments.
Prescription-grade hearing aids typically cost $2,000 to $8,000 or more per pair in 2026, with the higher end of that range applying to devices for significant hearing loss. Over-the-counter hearing aids for mild to moderate loss are available for $200 to $1,500, following the FDA’s 2022 ruling that created an OTC category.
OTC devices lack the audiologist programming that many people with significant hearing impairment need, and the gap in real-world performance becomes obvious quickly. Some Medicare Advantage plans include a hearing benefit, but coverage limits vary widely. Before enrolling in any Advantage plan, call the insurer and ask specifically what devices are covered and at what dollar amount, not just whether a “hearing benefit” exists.
The difference between a plan that covers $500 toward hearing aids and one that covers $2,500 is worth knowing before you sign enrollment papers. The most practical move for anyone approaching Medicare age: if you haven’t had a hearing evaluation recently and you’re still on employer coverage, schedule one now. If hearing aids are recommended, purchasing them while employer insurance is still active can save several thousand dollars compared to buying them once you’re on Medicare only.
Routine Vision Care: The Annual Exam Medicare Won’t Pay For
Parts A and B cover a large portion of your medical expenses after 65, but that doesn’t mean Medicare covers everything. Routine vision care is a clean example of what gets left out. Medicare doesn’t pay for annual eye exams for glasses or contacts, and it doesn’t cover eyeglasses or contact lenses, with one narrow exception: after cataract surgery, it covers one pair of standard frames or contact lenses.
What Medicare does cover is treatment for diagnosed eye disease. Glaucoma, macular degeneration, and diabetic retinopathy are medical conditions that trigger Part B coverage for related care. The routine annual exam that would catch those conditions early, before they’ve caused damage, falls outside what Medicare pays for.
A routine eye exam typically costs $100 to $200 out of pocket. Eyeglasses with progressive lenses generally run $400 to $700 or more. Across a retirement that may span two or three decades, those costs build steadily.
Medicare Advantage plans provide medical and drug coverage through private insurers, and many offer supplemental benefits for vision. If you’re in an Advantage plan, check what the vision benefit actually covers: the annual exam, plus a dollar amount toward frames or lenses. These are often capped annually, and a $150 vision allowance looks very different from a $300 one when you’re covering the rest yourself.
Medical Care Outside the United States
Original Medicare generally does not cover medical care outside the United States. For retirees who travel internationally, spend winters abroad, or are considering relocating to a lower-cost country, that’s a gap worth understanding clearly before departure rather than after a medical emergency.
A serious medical event abroad could trigger costs most people aren’t prepared for. Medical evacuation, being transported to a facility equipped to treat your condition or being flown back to the United States, can run $50,000 to $100,000.
Some Medigap plans offer limited international emergency coverage. Specifically, Medigap Plans C, D, F, G, M, and N include foreign travel emergency benefits, with a $250 deductible, 80% coverage of billed charges after that, and a lifetime maximum of $50,000. Medicare Advantage plans, for all their extra benefits, generally don’t extend coverage outside the U.S. either.
For any extended trip or planned relocation abroad, a standalone international health insurance policy or a comprehensive travel medical plan is the more reliable solution.

What to Do With All of This
Long-term care insurance is dramatically cheaper at 55 than at 65. Standalone dental plans impose waiting periods if you don’t buy them before you need a crown. Hearing aids cost less with employer insurance than without it.
The window to act affordably on most of these is before retirement, not after. If you’re still working and building savings, understanding what Medicare won’t cover is part of building a retirement plan that reflects what costs actually look like, rather than what people assume they’ll look like.
None of these gaps are secrets. They’ve been part of Medicare since the program launched in 1965. Medicare dental coverage, long-term care, hearing, vision, international care: each has a practical fix. But those fixes require time to research, price, and decide on.
