Medicare Doesn’t Cover These Routine Doctor Visits and That Can Lead to Surprise Bills

People entering Medicare often expect their healthcare routine to continue more or less unchanged. They had an annual physical through an employer plan, visited the dentist twice a year, scheduled an eye examination when their glasses needed updating and assumed Medicare would simply become the insurance company paying for those familiar appointments. That assumption can produce an unpleasant surprise.

Original Medicare covers an enormous range of medically necessary care and preventive services, but it does not cover everything people traditionally think of as routine healthcare. A comprehensive annual physical is one of the most notable exclusions. Routine dental cleanings, ordinary eye exams for glasses, hearing aids and many forms of routine foot care also generally fall outside Original Medicare. Medicare Advantage plans may add some of these benefits, but that is separate from what Parts A and B themselves cover.

The distinction becomes even more confusing because Medicare does cover a “Welcome to Medicare” preventive visit and yearly “Wellness” visits. Those appointments sound like annual physicals, but Medicare explicitly says they are not comprehensive physical examinations. Understanding the vocabulary Medicare uses can therefore be almost as important as understanding the medical care itself.

Your Annual Physical May Not Be the Visit Medicare Covers

One of the most common Medicare surprises occurs at the primary-care doctor’s office. A patient schedules what has always been called an annual physical, expecting a head-to-toe examination similar to the one previously covered by employer insurance. Original Medicare generally does not cover routine physical exams.

Instead, Medicare Part B offers specific preventive visits. During the first 12 months someone has Part B, Medicare covers one “Welcome to Medicare” preventive visit. The appointment reviews medical and social history, preventive screenings and vaccines, risk factors, medications and other information intended to establish a preventive-care plan. It can include measurements such as body mass index, a simple vision test, depression-risk review and discussion of advance directives.

Medicare makes an important point about this appointment: it is not a comprehensive physical examination. If the physician performs services beyond the covered preventive benefit, the patient can owe additional costs. Some added services may be subject to the Part B deductible and coinsurance, while services Medicare does not cover at all may become entirely the patient’s responsibility.

That is why the words used when scheduling an appointment matter. A beneficiary wanting Medicare’s covered introductory preventive service should ask for the “Welcome to Medicare” preventive visit rather than simply requesting an annual physical and assuming the two are interchangeable.

The Yearly Wellness Visit Is Not an Annual Physical Either

After the introductory period, Medicare Part B covers a yearly Wellness visit once every 12 months for eligible beneficiaries. The purpose is to develop or update a personalized prevention plan based on the person’s health and risk factors. Again, Medicare specifically says this is a conversation-based preventive visit rather than a routine physical examination.

The visit can include a health-risk assessment, height, weight and blood-pressure measurements, review of medical and family history, review of prescriptions and personalized health advice. Providers also perform a cognitive assessment looking for potential signs of dementia and can discuss advance-care planning, screenings and vaccinations.

When the provider accepts assignment, Medicare generally covers the Wellness visit without the Part B deductible or coinsurance. But that favorable treatment applies to the preventive visit itself. If a patient brings up a new medical condition and the physician evaluates or treats it during the same appointment, the additional service may be billed separately and normal Part B cost sharing can apply.

That explains why someone can legitimately receive a bill after a supposedly “free” Medicare Wellness visit. The Wellness component may have been covered at no cost while another medically necessary service provided during the same appointment generated ordinary Medicare charges.

Medicare Actually Covers Considerable Preventive Care

It would be misleading to characterize Medicare as a program that covers illness but not prevention. Although Medicare’s original benefit structure dates to 1965, Congress has expanded preventive coverage substantially over the decades.

Today Medicare covers numerous preventive screenings and vaccines when eligibility requirements are satisfied. The yearly Wellness visit itself is built around identifying recommended preventive services, and Medicare covers services ranging from many cancer screenings to cardiovascular testing, diabetes screening and various immunizations under applicable rules.

The more accurate distinction is that Medicare does not necessarily cover routine maintenance services in the same format private insurance historically offered them. It has its own statutory preventive benefits, eligibility requirements and billing categories.

That distinction is important because beneficiaries can accidentally pay for something Medicare would have covered if they request a different service from the one Medicare actually recognizes. The goal should never be manipulating billing terminology, but it should be making sure the appointment being scheduled corresponds to the benefit the patient actually wants.

Routine Eye Exams Are Usually Not Covered

Vision care creates another common surprise. Original Medicare generally does not cover routine eye examinations performed to determine a prescription for eyeglasses or contact lenses. Someone wanting a standard refraction because vision has changed will generally be responsible for the cost unless another insurance plan provides coverage.

That does not mean Medicare ignores eye disease. Part B can cover medically necessary diagnosis and treatment for eye conditions and covers specific preventive services for qualifying beneficiaries. For example, Medicare covers glaucoma screenings once every 12 months for certain people at elevated risk, including people with diabetes or a family history of glaucoma and members of specified higher-risk demographic groups.

Cataracts provide another useful example. Medicare Part B can cover qualifying cataract surgery and ordinarily covers one pair of eyeglasses with standard frames, or one set of contact lenses, after each covered cataract surgery that implants an intraocular lens. Ordinary eyeglasses and contacts outside that situation are generally not covered.

The same ophthalmologist’s office can therefore provide a service Medicare covers and another service it does not. The relevant question is not simply whether Medicare covers “eye doctors.” It is why the patient is seeing the eye doctor and which service is being performed.

Most Routine Dental Care Remains Outside Original Medicare

Dental coverage is one of Original Medicare’s largest gaps. Medicare generally does not pay for routine cleanings, fillings, ordinary tooth extractions, dentures or implants. Beneficiaries needing those services typically pay themselves or rely on separate dental insurance or additional benefits available through some Medicare Advantage plans.

The rules have become more nuanced for dental care connected directly with certain covered medical treatment. Medicare may cover qualifying dental examinations or treatment when those services are integral to treatment such as certain organ transplants, heart-valve procedures, cancer therapy or dialysis. It may also cover certain inpatient dental procedures when hospitalization is medically necessary because of the patient’s underlying condition or the severity of the procedure.

That does not transform Medicare into general dental insurance. Someone needing an ordinary cleaning or an implant because a tooth deteriorated should not assume the procedure becomes covered merely because dental treatment affects overall health.

Beneficiaries comparing Original Medicare with Medicare Advantage should consequently evaluate dental benefits carefully. An Advantage plan may advertise dental coverage, but annual allowances, networks, covered procedures and cost sharing can differ significantly among plans. “Dental included” is not enough information to determine whether an expensive crown or implant will actually be covered.

Hearing Aids Are Still a Major Coverage Gap

Original Medicare does not cover hearing aids or examinations performed specifically to fit hearing aids. The beneficiary generally pays the full cost unless another source of coverage applies.

Medicare can cover diagnostic hearing and balance examinations when they are medically necessary to determine whether treatment is needed for a condition. Once again, the reason for the visit changes the coverage.

An examination prompted by sudden hearing loss, dizziness or another medical problem can therefore be treated differently from a routine appointment designed to select and fit a hearing aid. Medicare Advantage plans frequently advertise hearing benefits, but the details need to be checked at the plan level.

This difference between diagnosis of a medical problem and routine hearing-aid services is representative of many Medicare coverage questions. Beneficiaries should ask what exact service is being ordered rather than whether Medicare broadly covers a particular specialty.

Routine Foot Care Is Usually Excluded Too

Routine podiatry provides another example. Medicare does not generally cover services such as cutting corns and calluses, trimming toenails or ordinary preventive foot maintenance. Those are typically considered routine foot care.

Medicare Part B can cover medically necessary treatment for foot injuries and diseases, including conditions such as bunion deformities, heel spurs and hammer toe. Certain beneficiaries with diabetes-related complications may also qualify for covered foot examinations and treatment under Medicare rules.

A podiatry appointment therefore is not automatically covered or excluded. Two patients can receive what appears superficially to be similar care but have different Medicare treatment because one has a qualifying medical condition and the other is receiving ordinary maintenance.

This is why documentation is important. The medical record has to support the condition and service actually provided rather than simply attaching a diagnosis code designed to generate payment.

Medicare Does Not Pay for Most Long-Term Custodial Care

Perhaps the most financially significant misunderstanding concerns long-term care. Original Medicare does not provide general coverage for custodial long-term care when someone primarily needs assistance with activities such as bathing, dressing, eating or using the bathroom. Medicare distinguishes this from qualifying skilled nursing or other medically necessary services.

That gap can involve far more money than routine dental or vision expenses. Someone who eventually needs years of help at home, in assisted living or in a nursing facility can face substantial costs that Medicare does not simply absorb.

Medigap does not convert Medicare into long-term-care insurance either. Medigap generally helps pay certain cost-sharing obligations for services Original Medicare covers; it does not ordinarily create coverage for services Medicare excludes altogether.

Families approaching retirement should therefore treat long-term-care planning as a separate financial issue. Assuming Medicare will pay simply because a person is elderly and needs significant help is one of the most expensive misconceptions in retirement planning.

Medigap Plan G Does Not Fill Every Medicare Coverage Gap

Medigap Plan G is popular because it covers many of the cost-sharing gaps left by Original Medicare for Medicare-covered services. Once applicable Medicare requirements are satisfied, standard Plan G can cover benefits including Part A coinsurance and deductible, Part B coinsurance and certain other standardized expenses.

But Medigap does not generally turn a non-covered service into a covered one. If Original Medicare does not cover an ordinary physical, routine dental cleaning or hearing aid, standard Plan G does not normally step in simply because Medicare rejected the bill.

Another point of confusion involves the deductible. Standard Plan G does not have a $283 “Plan G deductible.” The $283 figure is the 2026 Medicare Part B deductible, and standard Plan G does not cover that deductible for people newly eligible for Medicare after the statutory cutoff. Separately, insurers can sell a high-deductible version of Plan G, whose deductible is $2,950 in 2026.

The 2027 Part B deductible should not be assumed from the 2026 figure before CMS announces the new amount. Medicare figures frequently change annually, making current-year numbers a poor basis for quoting future-year costs prematurely.

A Billing Error Is Not Always Fixed by Changing “Routine” to “Diagnostic”

Medical coding can create legitimate claim problems, but beneficiaries should be cautious with advice telling a physician simply to change a service from “routine” to “diagnostic” so Medicare will pay it.

Medical claims must reflect the service that was actually provided and the documented reason it was medically necessary. If a test truly was ordered to investigate a symptom or manage a diagnosed condition but was incorrectly coded, the physician’s office can review the claim and correct an error. That is very different from relabeling a legitimately routine service solely to obtain Medicare reimbursement.

When an unexpected bill arrives, a beneficiary can first compare the provider’s bill with the Medicare Summary Notice and ask the provider’s billing department to explain the diagnosis and procedure codes submitted. If something appears inconsistent with what occurred, the patient can ask the provider to review the documentation and resubmit the claim if an actual error exists.

The practical rule is simple: do not immediately assume that either Medicare or the doctor’s office is correct. Investigate the reason for the denial before paying a large disputed bill, but insist that any correction accurately reflect the medical record.

Medicare Enrollment Periods Depend on the Individual Situation

The enrollment portion of Medicare can be just as confusing as the coverage rules. The Initial Enrollment Period generally lasts seven months around the month someone turns 65: three months before the birthday month, the birthday month and three months afterward. A person who postpones Part B because of qualifying group coverage based on current employment may later be able to use a Special Enrollment Period.

The CMS-40B form is used by someone who already has Part A and wants to enroll in Part B. It can be used in appropriate Initial, General or Special Enrollment Period circumstances, while someone using the working-aged Special Enrollment Period generally also provides Form CMS-L564 documenting qualifying employer coverage.

That means there is no universal rule telling every beneficiary to wait until December 1 to submit Form CMS-40B for a January effective date. The correct submission date and enrollment period depend on the person’s age, existing Part A status, employment coverage, desired Part B effective date and Social Security circumstances.

People transitioning from a spouse’s employer plan should confirm the timing with Social Security and the employer benefits office before terminating existing insurance. A gap between employer coverage and Medicare can be much more serious than paying an extra premium for one month.

The Best Question Is Not “Does Medicare Cover My Doctor?”

A provider can participate in Medicare while offering some services Medicare covers and others Medicare does not. That is why asking whether a doctor “takes Medicare” is only the beginning.

Before a routine appointment, beneficiaries should identify the specific purpose of the visit. Is it the Welcome to Medicare preventive visit, the yearly Wellness visit, evaluation of a new symptom or a comprehensive physical that Medicare does not cover? At an eye doctor, is it a routine refraction or treatment of cataracts? At a podiatrist, is it nail trimming or medically necessary treatment of a diagnosed condition?

Those distinctions determine coverage far more reliably than the name of the medical specialty. They also help beneficiaries ask better questions before the service occurs, when there is still time to understand possible charges.

Medicare is not simply a less generous version of employer insurance. It is a different insurance system with its own categories, preventive benefits and exclusions. Learning those categories can save beneficiaries from assuming that every familiar healthcare routine will follow them automatically into retirement.

The greatest surprise is often not that Medicare covers too little. It is that Medicare may cover substantial care under one definition while declining to pay for a seemingly similar service under another. Knowing the difference between a physical and a Wellness visit, between routine vision care and treatment of eye disease, or between ordinary dental work and medically necessary dental services can prevent both gaps in care and expensive misunderstandings at the billing office.
