For many Americans, enrolling in Medicare feels like a safety net finally snapping into place after decades of work. It’s often described as the health coverage that carries people through retirement. Sadly, the reality can surprise many new beneficiaries. It helps with a wide range of hospital and medical costs, yet Medicare was never designed to cover every healthcare need older adults might face.
That gap can lead to unexpected bills. Some services fall completely outside Medicare’s rules, while others are only partially covered, leaving patients responsible for high out-of-pocket costs.
According to the recent data, retirees spend thousands each year on healthcare expenses not covered by Medicare. Knowing where those gaps exist can help people plan, choose supplemental coverage wisely, and avoid financial surprises down the road.
1. Long-Term Nursing Home Care

Some Americans may assume Medicare will pay for long-term stays in a nursing home, but that isn’t the case. Medicare only covers short-term skilled nursing care under specific conditions, typically following a hospital stay.
The Centers for Medicare & Medicaid Services makes this clear in its guidance for beneficiaries. “Most long-term care is custodial care,” the agency explains. “Medicare doesn’t cover long-term care if that’s the only care you need.”
That means assistance with everyday activities like bathing, dressing, and eating usually falls outside Medicare’s coverage. For retirees who may eventually need this level of support, planning is essential. Long-term care insurance, Medicaid eligibility, or personal savings are often the main ways families cover these costs.
2. Most Dental Care

Routine dental care is one of the most common health expenses older adults must pay for themselves. Because oral health affects everything from nutrition to heart health, many retirees choose to purchase standalone dental insurance plans or discount dental memberships. Others budget for annual dental costs directly.
“In most cases, Medicare doesn’t cover dental services like routine cleanings, fillings, tooth extractions (removals), or items like dentures and implants,” reads the official Medicare page. A lifetime of good habits supported by a private dental insurance plan is the way forward.
3. Routine Vision Care and Eyeglasses

Eyesight naturally changes with age, yet routine eye exams and corrective lenses are generally not covered by Medicare. Things like contact lenses or eye exams fall outside the usual jurisdiction.
There are a few exceptions, such as eye exams related to diabetes or screening for glaucoma in higher-risk patients. Medicare may also cover one pair of glasses after cataract surgery with an implanted lens. Still, most seniors pay out of pocket for regular vision care unless they enroll in a Medicare Advantage plan that includes vision benefits.
4. Hearing Aids and Hearing Exams

Hearing loss becomes more common with age, but Medicare typically does not cover hearing aids. Considering that one-in-three adults aged between 65 and 74 have hearing loss, this may come as a surprise. Even some private insurers won’t cover this issue.
Furthermore, as hearing aids can cost thousands of dollars, this gap has drawn increasing attention from policymakers. Some Medicare Advantage plans offer limited hearing benefits, while new over-the-counter hearing aids approved by the FDA may help reduce costs.
Thankfully, the National Council on Aging (NCOA) also lists the charities that can assist those without the right insurance.
5. Routine Foot Care

Foot problems can affect mobility and quality of life, yet Medicare usually excludes routine foot care such as nail trimming or callus removal. Yet, there are some conditions that may not exempt certain claimants.
The Department of Health and Human Services (HHS) dictates that a small stipulation applies. Those with “systemic medical conditions that increase the risk of infection or injury if the services are not performed by a medical nonprofessional,” might qualify.
Medicare may also cover medically necessary foot care for people with certain conditions, like diabetes-related nerve damage. For others, podiatry visits for routine maintenance usually come out of pocket.
6. Cosmetic Surgery

Most cosmetic or plastic surgery is not covered by Medicare or private insurance because it covers improving one’s appearance. Procedures done purely for appearance rather than medical necessity typically fall outside Medicare coverage.
However, there are exceptions. If a procedure is medically necessary, like reconstructive surgery after an accident or cancer treatment, Medicare may provide coverage. Nonetheless, that lip filler or tummy-tuck remains a personal expense.
“It may cover plastic surgery when it becomes necessary to repair damage from an illness, accident, or due to a development issue with a bodily area,” states Medical News Today. Certain cases qualify, like post-accidental or mastectomy surgery, and certain cosmetic corrections of deformities.
7. Care Outside the United States

Living overseas might come with wonderful fringe benefits, but Medicare is unlikely to be one of them, even for foreign-based armed forces members. For retirees who enjoy traveling or even living abroad part-time, private or foreign state coverage is necessary. A few limited exceptions exist, such as emergency care near the U.S. border.
Because of this gap, travelers often purchase travel medical insurance before leaving the country. There is the TRICARE option, though it can come with complications.
“Medicare doesn’t cover health care outside of the U.S. or U.S. territories, so TRICARE is the primary payer,” states the website. It means you are responsible for deductibles, and you may need to pay upfront for later reimbursement.
8. Alternative Medicine Treatments

There has been an obvious rising trend in alternative medical treatments, many of which are now being used as standard. Complementary and alternative therapies, such as acupuncture, naturopathy, and herbal treatments, are popular among many older adults. Yet, most of these services are not covered.
Healthline’s Tess Catlett confirms this in a guide to alternative medicine coverage. She adds that “Medicare Advantage (Part C) plans may offer broader coverage for alternative treatments.” However, one must research their specific plan, and there must be a licensed practitioner involved.
As always, there are small exceptions. Medicare now covers acupuncture for chronic lower back pain in some cases. But many other alternative therapies remain outside the program’s benefits.
9. Concierge or Membership-Based Doctors

Some physicians operate “concierge” or membership-based practices where patients pay annual fees for enhanced access or longer appointments. Of course, being capable of paying this means you are financially better off than most. Therefore, such fees are typically not reimbursed by Medicare.
Furthermore, one must also be careful, warns the Medicare guide on concierge care. “Your doctor may recommend services that Medicare does not cover or offers too frequently,” it reads. “Make sure to ask your doctor about the reasons for these recommendations and what Medicare will actually cover.”
10. Personal Care Services at Home

Medicare does cover some home health services, but only when they are medically necessary and provided by skilled professionals. For everyday assistance, such as help with cooking, dressing, or housekeeping, Medicare generally does not pay.
AARP confirms that “Medicare will cover part-time or intermittent skilled nursing care, therapy and other aid,” though only on your doctor’s orders.
It won’t cover care for daily activities, which might eventually need family or privately covered home assistance. Growing old is no joke, so being prepared before it is too late brings peace of mind.
11. Most Prescription Drugs Without a Part D Plan

Prescription medications can be one of the largest healthcare costs for retirees. While Medicare provides drug coverage through Part D plans, people without one may face high out-of-pocket expenses.
Industry research platform PhRMA reported in 2025 that some Medicare Part D plans were denying up to 70% of claims for four chronic illnesses.
“Pharmacy benefit managers (PBMs) and plans increasingly use aggressive tactics to deny coverage,” writes Caroline Dunne. She lists “excluding physician-prescribed medicines from coverage” among other hard conditions.
