What Does Medicare Not Cover?

Medicare provides solid coverage for a wide range of medical needs, but it is not all-encompassing. Many people are surprised to discover that some common healthcare services are not included in Original Medicare, and those gaps can lead to unexpected out-of-pocket costs.

Knowing what Medicare does not cover helps you plan ahead and decide whether additional coverage makes sense for your situation.

The Major Coverage Gaps in Original Medicare

Routine Dental Care

Original Medicare does not cover routine dental care. This includes:

• Cleanings and checkups
• Fillings and extractions
• Dentures
• Most oral surgery

Medicare may cover dental services that are part of a covered procedure (for example, a jaw reconstruction following an accident), but day-to-day dental care is not included. This is one of the most common gaps that people choose to fill with a separate dental plan or a Medicare Advantage plan that includes dental benefits.

Routine Vision Care

Medicare does not cover:

• Routine eye exams for prescribing glasses
• Eyeglasses or contact lenses (with rare exceptions, such as after cataract surgery)
• Most vision care beyond medically necessary treatments

Medicare Part B does cover some eye-related medical conditions — like glaucoma screenings and treatment for macular degeneration — but standard vision care for most people requires separate coverage.

Hearing Aids and Routine Hearing Exams

Original Medicare does not cover hearing aids or the exams needed to fit them. Given that hearing loss is common among older adults, this is a significant gap for many people. Medicare does cover diagnostic hearing exams if ordered by a doctor, but that is different from routine hearing care.

Long-Term Custodial Care

Perhaps the most costly gap: Medicare does not cover long-term custodial care. This means:

• Assisted living facilities
• Nursing home care that is primarily custodial (help with daily activities)
• Most in-home personal care (bathing, dressing, meal preparation)

Medicare covers skilled nursing facility care only after a qualifying hospital stay and only for a limited time. Once the skilled care need ends, Medicare coverage ends too.

Routine Foot Care

Medicare covers medically necessary foot care, but routine foot care — such as routine nail trimming or callus removal — is generally not covered unless a qualifying medical condition is present.

Cosmetic Procedures

Elective cosmetic surgery is not covered by Medicare, even if it is performed in a hospital.

Care Outside the United States

With very few exceptions, Medicare does not cover healthcare received outside the United States. Some Medigap plans include limited foreign travel emergency coverage, and travel medical insurance is another option if you spend time abroad.

No Annual Out-of-Pocket Limit on Original Medicare

This one is less a missing service than a missing protection, and it catches people off guard: Original Medicare by itself has no annual out-of-pocket maximum. There is no built-in ceiling on what a long or serious health event could cost you. A Medigap policy reduces or eliminates most of that cost sharing, and Medicare Advantage plans include an annual in-network out-of-pocket maximum.

• Dental, vision, and hearing care are the most common gaps in Original Medicare and affect millions of people.
• Long-term custodial care is not covered — this is an important planning consideration, especially as healthcare needs evolve.
• Supplemental options exist — through standalone dental/vision plans, Medicare Advantage plans with extras, or ancillary coverage like hospital indemnity and critical illness insurance.

A Simple Planning Framework

Rather than reacting to each gap separately, it helps to work through four questions:

1. What routine care do I actually use — dental, vision, hearing?
2. How much out-of-pocket exposure am I comfortable carrying on hospital and Part B cost sharing?
3. Do I need prescription drug coverage? (Almost always yes.)
4. Is long-term care a meaningful risk given my family history and finances?

Your answers point to which gaps are worth closing and which are reasonable to leave open.

How to Fill the Gaps

There are several ways to address what Medicare does not cover:

Medicare Advantage plans often include dental, vision, and hearing benefits as part of the plan. If bundled coverage appeals to you, this is one path to consider.

Standalone dental and vision plans are available separately if you prefer to stay on Original Medicare with a Medigap plan.

Ancillary/supplemental insurance — such as hospital indemnity, critical illness, or AD&D coverage — can provide additional financial protection for specific events that Medicare may not fully cover.

Long-term care insurance is a separate product that specifically covers custodial care in nursing homes, assisted living, or at home. It requires planning ahead, as premiums increase significantly with age.
