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, age-related macular degeneration, or cataracts. A routine eye exam to check your vision and update your glasses or contact lens prescription is not covered. If you need an exam to diagnose or monitor a disease, Medicare pays 80 percent of the approved amount after you meet your Part B deductible. You pay the remaining 20 percent.

The distinction matters because many people schedule an eye exam thinking it will be covered, then learn at the desk that their visit is classified as routine. Knowing the difference before you call an eye doctor can save you from unexpected bills.

Key Takeaways

  • Medicare Part B covers eye exams only when a doctor documents a medical eye condition, not for routine vision checks or prescription updates.
  • If your exam is covered, Medicare pays 80 percent after your Part B deductible; you pay 20 percent of the approved amount.
  • Routine eye exams and eyeglasses or contact lenses are not covered by Original Medicare, though some Medicare Advantage plans include vision benefits.
  • You must see an ophthalmologist (a medical doctor) for a covered exam; optometrists can perform exams but may bill differently depending on the reason for the visit.
  • If you have a medical eye condition, ask your doctor whether the exam will be billed as a medical visit before your appointment.

What counts as a covered medical eye exam

A covered eye exam must be ordered by a doctor to diagnose or monitor a specific eye disease or condition. Common reasons Medicare covers an exam include checking for glaucoma (high pressure in the eye), monitoring diabetic retinopathy (damage to blood vessels in the retina from diabetes), evaluating cataracts, assessing age-related macular degeneration, or investigating sudden vision changes or eye pain.

The key is that the exam serves a medical purpose, not a refractive one. Refractive means checking your vision to see whether you need glasses or a stronger prescription. Even if you have never had an eye exam and your vision is blurry, if the blurriness is not caused by a diagnosed disease, the exam is considered routine and is not covered.

Your primary care doctor can order a medical eye exam and refer you to an eye specialist. You do not need a referral to see an ophthalmologist under Medicare, but having a doctor's order helps clarify that the visit is for a medical reason.

The difference between ophthalmologists and optometrists

An ophthalmologist is a medical doctor (MD or DO) who specializes in eye care. They can perform eye exams, diagnose eye diseases, prescribe glasses and contacts, and perform surgery. Medicare covers medical eye exams performed by ophthalmologists.

An optometrist is not a medical doctor but a licensed professional who can perform eye exams and prescribe glasses and contacts in most states. Medicare does not cover routine exams by optometrists. However, some optometrists can bill Medicare for a medical eye exam if they are evaluating a specific eye disease under a doctor's order. Before scheduling, ask the optometrist's office whether they bill Medicare for medical exams and whether your reason for the visit qualifies.

What is not covered by Medicare

Routine eye exams — exams done to check your vision and update your prescription — are not covered by Original Medicare. This includes exams for reading glasses, distance glasses, or contact lenses, even if you have never had an exam before.

Eyeglasses, contact lenses, and contact lens fittings are also not covered. If you need glasses after a covered medical eye exam, you pay the full cost out of pocket. Some Medicare Advantage plans (Part C) include vision benefits that cover routine exams, glasses, or contacts, but coverage varies widely by plan. Check your plan documents or call your plan to see what vision services are included.

How to find out whether your exam will be covered

Before you schedule or go to an appointment, call the eye doctor's office and tell them the reason for your visit. Ask them directly: "Will this visit be billed to Medicare as a medical exam, or as a routine exam?" The office staff should be able to tell you based on your medical history and the reason your doctor referred you.

If the office is unsure, ask to speak with the billing department. You can also call Medicare at 1-800-MEDICARE to ask whether a specific condition or reason for an exam is typically covered, though Medicare cannot tell you whether your individual visit will be covered until the claim is submitted.

If you are told the exam is routine and not covered, ask whether the office offers a cash price or a discount for uninsured patients. Some practices charge less if you pay out of pocket than if they bill insurance.

What you pay if the exam is covered

If your eye exam is covered as a medical visit, you pay 20 percent of the Medicare-approved amount after you have met your Part B deductible for the year. The deductible for 2024 is $240, though this amount may change each year. Once you meet the deductible, Medicare pays 80 percent and you pay 20 percent for the rest of the year.

The amount you pay depends on what the eye doctor charges and what Medicare approves. If the doctor charges more than the Medicare-approved amount, you are responsible only for 20 percent of the approved amount, not the difference. Ask the office for an estimate of the Medicare-approved charge before your visit so you know what to expect.

If you have a Medigap (supplemental insurance) policy, it may cover some or all of your 20 percent coinsurance. Check your policy or call your Medigap insurer to see what is covered.

Medicare Advantage vision coverage

If you are enrolled in a Medicare Advantage plan (Part C), your plan may cover routine eye exams, glasses, or contact lenses. Coverage varies significantly from plan to plan — some plans cover one routine exam per year, others cover two, and some cover none. Some plans cover a set dollar amount toward glasses or contacts each year; others do not.

Check your plan's Summary of Benefits or call your plan's customer service to find out what vision services are included. If your plan does cover routine exams, you typically pay a copay (a fixed amount like $10 or $25) rather than a percentage of the cost. Medical eye exams for a diagnosed condition are usually covered the same way as they are under Original Medicare.

Frequently Asked Questions

Will Medicare cover my eye exam if I have diabetes?

Only if the exam is to check for diabetic retinopathy or other diabetes-related eye damage. A routine exam to update your glasses prescription is not covered, even if you have diabetes. Ask your doctor to order an exam specifically to screen for diabetic eye disease if you have not had one recently.

Do I need a referral to see an eye doctor?

No, Medicare does not require a referral to see an ophthalmologist. However, having your primary care doctor order the exam or write a referral helps document that the visit is for a medical reason, which can prevent billing confusion.

What if I go to the eye doctor and they say the exam is not covered?

Ask the office to bill it as routine and give you a cash price. You can also ask whether they will submit it to Medicare anyway and let you know the result. If Medicare denies the claim, the office should send you a notice explaining why. You can then decide whether to pay out of pocket or appeal.

Are glasses covered if my eye exam is covered?

No. Medicare covers the medical eye exam but not the glasses or contact lenses themselves. You pay the full cost for frames and lenses out of pocket. Some Medicare Advantage plans include a glasses benefit, so check your plan.

How often can I have a covered eye exam?

There is no set limit, but Medicare covers exams only when medically necessary. If you have glaucoma or diabetic retinopathy, your eye doctor may recommend exams every few months or once a year. Medicare will cover exams at the frequency your doctor orders, as long as the condition warrants it.
