Original Medicare Coverage Gaps

What Does Medicare Not Cover?

Original Medicare covers a wide range of medically necessary hospital and medical services, but it does not cover everything. This guide explains the most important Part A and Part B coverage gaps, the exceptions that matter, and where people often look for additional coverage.

Quick Answer

What is not covered by Original Medicare?

Common Original Medicare exclusions include long-term custodial care, routine eye exams for prescription glasses, hearing aids and fitting exams, routine physical exams, massage therapy, concierge membership fees, most cosmetic surgery, and most routine dental care. Original Medicare also generally does not cover health care outside the United States, except in limited situations.

The important word is routine. Medicare may cover related services when they are medically necessary or directly connected to a covered treatment. That is why checking the exact service before assuming it is excluded can prevent expensive surprises.

Coverage Gaps

Common Services Original Medicare Does Not Cover

These are some of the most important gaps to understand before you assume Medicare will pay. Several categories have limited exceptions, so the details matter.

Long-Term Custodial Care

Not covered

Medicare does not pay for long-term care, also called custodial care, when the main need is help with activities such as bathing, dressing, eating, toileting, or other daily personal care.

Important distinction: Medicare may cover qualifying short-term skilled nursing facility care and certain home health services. Skilled care is not the same as ongoing custodial long-term care.

Most Routine Dental Care

Usually not covered

Original Medicare generally does not cover routine dental services such as cleanings, fillings, most tooth extractions, dentures, or implants.

Exceptions exist: Medicare may cover certain dental services that are directly related to specific covered medical treatments, including some services connected with organ transplants, heart valve procedures, cancer treatment, or dialysis for End-Stage Renal Disease.

See our deeper explanation: Why Doesn't Medicare Cover Dental Care?

Routine Eye Exams and Most Eyeglasses

Routine care not covered

Original Medicare does not cover routine eye exams, sometimes called refractions, for prescription eyeglasses or contact lenses. It also does not usually cover eyeglasses or contacts.

One important exception: Part B covers one pair of standard-frame eyeglasses or one set of contact lenses after each covered cataract surgery that implants an intraocular lens.

Hearing Aids and Fitting Exams

Not covered by Original Medicare

Original Medicare does not cover hearing aids or exams performed specifically to fit hearing aids.

Medicare can cover certain diagnostic hearing and balance exams when they are medically necessary. That is different from routine hearing-aid fitting services.

Routine Physical Exams

Routine physical not covered

Original Medicare does not cover a traditional routine physical exam just because you want a yearly physical.

But Medicare does cover preventive visits: Part B covers the yearly Medicare Wellness visit for eligible beneficiaries. The Wellness visit is focused on prevention planning and is not the same as a routine physical exam.

Most Cosmetic Surgery

Usually not covered

Medicare generally does not cover surgery performed only to change appearance.

Medical exceptions matter: Medicare may cover procedures needed because of an accidental injury, to improve the function of a malformed body part, or for certain reconstructive care such as breast reconstruction following a mastectomy for breast cancer.

Massage Therapy

Not covered

Original Medicare does not cover massage therapy, even when a person uses massage as part of a broader approach to pain management.

Do not assume that every pain treatment is excluded. Medicare coverage depends on the specific service, medical necessity, provider requirements, and Medicare coverage rules.

Concierge Membership Fees

Membership fee not covered

Medicare does not pay the membership or retainer fee charged by a concierge medical practice.

Covered medical services are different: A concierge doctor who participates in Medicare must still follow Medicare rules for Medicare-covered services. The membership fee itself is a separate non-covered charge.

Adult Diapers and Incontinence Supplies

Not covered

Original Medicare does not cover adult diapers or incontinence supplies. You generally pay 100% of the cost for these non-covered items.

Some Medicare Advantage plans may offer additional benefits or allowances. Benefit details vary by plan and area.

Health Care Outside the United States

Usually not covered

Original Medicare generally does not cover medical care you receive outside the United States.

Limited exceptions apply: Medicare may pay in certain situations involving a foreign hospital that is closer than an appropriate U.S. hospital, certain travel through Canada between Alaska and another state, or qualifying care on a cruise ship.

Services From Providers Who Opt Out of Medicare

Generally not paid by Medicare

Medicare generally will not pay for covered items or services you receive from a doctor or other provider who has formally opted out of Medicare.

Emergency exception: Medicare may still cover emergency or urgently needed services in certain situations.

Provider billing rules can be confusing. See Medicare Assignment, Costs, and Provider Billing .

Common Supplies Used at Home

Many are not covered

Part B usually does not cover common disposable medical supplies you use at home, such as ordinary bandages and gauze.

Durable medical equipment is a different category. Medicare can cover qualifying equipment, such as certain walkers, wheelchairs, hospital beds, and other items, when Medicare requirements are met.
Key Distinction

Skilled Care and Long-Term Care Are Not the Same Thing

One of the most expensive Medicare misunderstandings is assuming that a Medicare-covered skilled nursing stay means Medicare will also pay for indefinite nursing-home or custodial care.

Medicare May Cover Qualifying Skilled Care

Part A can cover qualifying short-term skilled nursing facility care when Medicare's eligibility and medical-necessity requirements are met. Medicare can also cover certain skilled home health services.

Medicare Does Not Cover Ongoing Custodial Care

If the primary need is long-term help with daily living rather than skilled medical care, Medicare generally does not pay for that care, whether it is delivered at home, in assisted living, or in a nursing home.

Next Steps

How People Fill Medicare Coverage Gaps

The right approach depends on the type of gap. Medicare Advantage, Medigap, Part D, Medicaid, employer coverage, and private insurance solve different problems.

1

Medicare Advantage

Medicare Advantage plans must cover Medicare-covered services and may include extra benefits that Original Medicare does not, such as certain dental, vision, or hearing benefits. Benefits, provider networks, costs, and rules vary by plan.

2

Medigap

Medigap primarily helps pay your share of costs for services Original Medicare covers. It generally does not add routine dental, vision, hearing-aid, or long-term-care coverage. Some Medigap plans include limited foreign travel emergency benefits.

3

Medicare Part D

Original Medicare Part A and Part B are not designed to provide broad retail prescription drug coverage. A separate Part D plan, or a Medicare Advantage plan with drug coverage, can provide Medicare prescription drug coverage.

4

Other Coverage

Medicaid, employer or retiree coverage, stand-alone dental or vision insurance, long-term care insurance, and other private coverage may help with gaps that Medicare does not cover. Eligibility and benefits vary.

Important

A Medicare Supplement Does Not Automatically Cover Everything Medicare Excludes

This distinction is worth making explicit because it is one of the most common sources of confusion.

Medigap Rule of Thumb

Medigap is mainly designed to help with cost-sharing for Medicare-covered services.

A standardized Medicare Supplement policy can help pay certain deductibles, coinsurance, and copayments associated with Original Medicare. It generally does not turn routine dental care, routine vision care, hearing aids, or long-term custodial care into covered Medicare services. Some Medigap plans do provide limited foreign travel emergency coverage.
