Medicare covers some eye exams, but not all, and the coverage depends on whether you have a medical reason for the visit
Medicare Part B covers an eye exam only if you have a medical condition affecting your eyes — such as diabetes, glaucoma, macular degeneration, or cataracts — and your doctor refers you to an ophthalmologist or optometrist for diagnosis or treatment. Medicare does not cover routine eye exams done for the purpose of getting a glasses or contact lens prescription. If you go in for a standard vision check to see if you need new glasses, you pay the full cost yourself.
The distinction matters because many people assume Medicare covers all medical visits. It does not. A visit to check your vision and update your prescription is considered a routine service, not a medical treatment, even though an eye care professional performs it. If you have a diagnosed eye disease, however, the exam to monitor or treat that disease is covered.
You also need to understand the difference between the two types of eye care professionals. An ophthalmologist is a medical doctor who can perform surgery and prescribe medication. An optometrist is not a medical doctor but can perform exams and prescribe glasses and contacts. Medicare covers exams by either type if there is a medical reason, but you must see someone who accepts Medicare assignment to get the coverage.
Key Takeaways
- Medicare Part B covers eye exams only when you have a diagnosed eye disease or condition and need the exam for diagnosis or treatment, not for a routine vision check.
- Routine eye exams for glasses or contact lens prescriptions are not covered by Medicare, and you pay the full cost out of pocket.
- You must see an eye care provider who accepts Medicare assignment for the exam to be covered under Part B.
- If you have Medicare Advantage (Part C), your plan may cover routine eye exams and eyeglasses as an added benefit, so check your plan documents.
- Diabetics and people with glaucoma, macular degeneration, or cataracts should ask their primary care doctor for a referral to may support the exam is coded as medically necessary.
What Medicare Part B covers for eye exams
Medicare Part B covers the cost of an eye exam when an ophthalmologist or optometrist performs it to diagnose or monitor a medical eye condition. Common conditions that trigger coverage include diabetic retinopathy (damage to the blood vessels in the retina caused by diabetes), glaucoma, age-related macular degeneration, cataracts, and dry eye disease. The exam itself is covered at 80 percent of the Medicare-approved amount after you meet your Part B deductible, which means you pay 20 percent coinsurance.
The key word is medical. The exam must be ordered because you have symptoms or a known condition, not because you want to know if your vision has changed. If your doctor suspects you have glaucoma and refers you to an eye specialist for testing, that visit is covered. If you straightforward want to see whether you need new glasses, it is not.
You also need to make sure the provider accepts Medicare assignment. This means they have agreed to accept Medicare's approved amount as full payment for the service. If they do not accept assignment, you may be charged more, and Medicare will pay less. Before you schedule, call the office and ask whether they accept Medicare assignment.
What Medicare does not cover for vision care
Medicare Part B does not cover routine eye exams, eyeglasses, contact lenses, or eye exams for the purpose of fitting glasses or contacts. It also does not cover the cost of frames or lenses. If you need new glasses and do not have a medical reason for the eye exam, you pay for the entire visit and the glasses yourself.
Refractive errors — nearsightedness, farsightedness, and astigmatism — are not considered medical conditions by Medicare, even though they affect your vision. An exam to measure your prescription and fit you for glasses is a routine service. Some people confuse this with a medical eye exam and are surprised when they receive a bill.
Medicare also does not cover low-vision aids, magnifying devices, or other visual aids, though some Medicare Advantage plans may offer limited coverage. If you have significant vision loss, ask your doctor about a referral to a low-vision specialist, who may be able to recommend devices that are covered under other programs.
How to know if your eye exam will be covered
The simplest way to find out is to tell your primary care doctor about your eye symptoms or condition and ask for a referral to an eye care provider. When your doctor refers you, they are documenting that the visit is medically necessary. Write down the reason for the referral — for example, "monitoring glaucoma" or "diabetic retinopathy screening" — and bring it with you to the appointment.
When you call to schedule the appointment, tell the office staff the reason for your visit and ask them to confirm that Medicare will cover the exam. Ask specifically whether the provider accepts Medicare assignment. If the office is unsure, ask them to contact Medicare directly or have them give you the number for your local Medicare carrier, which can answer coverage questions before your visit.
Do not assume that because you are seeing an eye doctor, the visit is covered. Many eye care offices see both routine patients (who pay out of pocket) and medical patients (who are covered by insurance). The difference is in the reason for the visit and how it is coded in the billing system.
Medicare Advantage plans and vision coverage
If you have Medicare Advantage (Part C), your coverage for eye exams and vision care may be different from Original Medicare. Many Medicare Advantage plans include vision benefits as an added feature, which may cover routine eye exams, eyeglasses, and contact lenses. Some plans cover one eye exam per year; others cover two. Some plans also include a dollar amount toward frames and lenses.
The catch is that coverage varies widely from plan to plan and from year to year. You need to check your specific plan's documents or call the plan's customer service line to find out what is covered. Do not assume that because one Medicare Advantage plan covers routine eye exams, yours does too.
If you are thinking about switching to a Medicare Advantage plan or are in the open enrollment period, vision coverage is one factor to consider, especially if you need new glasses or contacts regularly. Some plans offer better vision benefits than others, and the cost of the plan plus your out-of-pocket costs for vision care may be lower with one plan than another.
What to bring to your eye exam appointment
Bring your Medicare card and any referral paperwork from your doctor. If you have a Medicare Advantage plan, bring that card instead. Bring a list of all medications you are taking, because some eye conditions are related to medication side effects, and the eye doctor may need to know what you are on.
If you have had previous eye exams or imaging (such as optical coherence tomography or visual field testing), ask whether those records are available and whether the new office can obtain them. This saves time and money because the doctor may not need to repeat tests that were done recently.
Arrive early to allow time for check-in. The office will likely ask you to sign a form confirming that you understand your financial responsibility. Read this carefully. If the form says you are responsible for the full cost of the visit, ask the office to clarify whether the visit is being billed to Medicare or to you.
If you do not have Medicare coverage for an eye exam
If your eye exam is not covered by Medicare, you have several options. You can pay out of pocket at the time of the visit. Many eye care offices offer discounts for uninsured or out-of-pocket patients, so ask whether a discount is available before you pay.
You can also look for a community health center or a vision clinic that offers exams on a sliding fee scale based on income. Many areas have these clinics, and they can perform routine eye exams and fit you for glasses at a lower cost than a private practice. To find one near you, search online for "community health center" or "vision clinic" plus your city name, or call 211 to ask for referrals.
If you are having vision problems and are not sure whether the issue is routine or medical, start with your primary care doctor. They can examine your eyes and refer you to a specialist if needed. This way, if there is a medical reason for the problem, the specialist visit may be covered by Medicare.
Frequently Asked Questions
Does Medicare cover eye exams for diabetics?
Yes, if the exam is to screen for or monitor diabetic retinopathy. Diabetics should have their eyes examined at least once a year by an eye care professional, and Medicare covers this exam if it is ordered by your doctor for that reason. Make sure your primary care doctor refers you and documents that the visit is for diabetic eye screening.
Will Medicare pay for new glasses after cataract surgery?
Medicare covers the eye exam after cataract surgery if it is performed by the surgeon or another eye care provider to check the surgical result. However, Medicare does not cover the cost of glasses or contacts themselves. You pay for the frames and lenses out of pocket, though some Medicare Advantage plans may cover part of this cost.
What if my eye doctor says I need an exam but I am not sure if Medicare will cover it?
Call your local Medicare carrier before the appointment and describe your symptoms or condition. The carrier can tell you whether the exam is likely to be covered. You can find your carrier's phone number on the back of your Medicare card or by visiting Medicare.gov and entering your state.
Can I use my vision insurance and Medicare at the same time?
If you have both Medicare and a separate vision insurance plan, you can use both. Medicare pays first for medically necessary exams, and your vision plan may cover routine exams or glasses. Tell both your Medicare provider and your vision plan provider that you have both coverages so they can coordinate benefits correctly.
Does Medicare cover contact lenses?
No. Medicare does not cover contact lenses or the fitting for contact lenses. If you need contacts, you pay for them out of pocket. Some Medicare Advantage plans may offer a small benefit toward contacts, so check your plan documents if you have one.
