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 one routine eye exam every 24 months if you have diabetes or a history of glaucoma. For any other reason — including a regular checkup or new glasses — you pay the full cost yourself. If you have a medical eye condition like macular degeneration, cataracts, or diabetic retinopathy, Medicare covers the exam that diagnoses or monitors it. The difference matters because "routine" and "medical" are not the same thing to Medicare, and your doctor's reason for seeing you determines what you owe.

Medicare does not cover eyeglasses, contact lenses, or the eye exam needed to prescribe them, with one exception: after cataract surgery, Medicare covers one pair of glasses or contact lenses as part of your surgical care. Hearing aids and routine vision correction are among the few things Original Medicare leaves to you.

Key Takeaways

  • Medicare Part B covers one routine eye exam every 24 months only if you have diabetes or glaucoma; otherwise you pay the full cost.
  • Exams for medical eye conditions — cataracts, macular degeneration, diabetic retinopathy, and others — are covered when your doctor documents the medical reason.
  • Eyeglasses and contact lenses are not covered except for one pair after cataract surgery.
  • Medicare Advantage plans may cover routine eye exams and glasses, so check your plan's vision benefits before paying out of pocket.
  • You can see any ophthalmologist or optometrist who accepts Medicare; you do not need a referral.

When Medicare Part B covers an eye exam

Medicare Part B covers a dilated eye exam once every 24 months if you have been diagnosed with diabetes or glaucoma. The exam must be performed by an ophthalmologist or optometrist, and Medicare pays 80 percent of the approved amount after you meet your Part B deductible. You pay 20 percent of the cost, which is typically $20 to $50 depending on your location and the provider.

If you have a medical eye condition that is not diabetes or glaucoma — such as age-related macular degeneration, cataracts, dry eye disease, or a history of retinal detachment — Medicare covers the diagnostic exam and follow-up visits. Your doctor must document the medical reason for the visit in your chart. A visit coded as "routine eye exam" or "vision screening" will not be covered unless you have diabetes or glaucoma.

The key is the reason your doctor documents for the visit. If you go in for a checkup and your doctor finds a cataract, the exam is covered because it becomes a medical visit. If you go in for a checkup and nothing is found, you may receive a bill. Ask your eye doctor before the visit whether they will code it as routine or medical, and what Medicare will cover.

What Medicare does not cover for vision

Medicare does not cover eyeglasses, bifocals, trifocals, or contact lenses under any circumstance except one: after cataract surgery, Medicare covers the cost of one pair of glasses or contact lenses as part of your surgical benefit. This is the only time Medicare pays for vision correction.

Routine eye exams — the kind you get to check if your vision has changed or to get a new prescription — are not covered unless you have diabetes or glaucoma. Refractive errors (nearsightedness, farsightedness, astigmatism) are not considered medical conditions by Medicare, so the exam to diagnose them is your responsibility. Vision screening at a primary care visit is also not covered.

If you need glasses or contacts, you can buy them from any optician or online retailer. Many offer discounts for seniors, and some community health centers offer low-cost frames. Ask your eye doctor for your prescription and pupillary distance (PD) — they must give it to you by law — and shop around.

How Medicare Advantage plans handle vision coverage

Medicare Advantage (Part C) plans often include vision benefits that Original Medicare does not. Many plans cover one routine eye exam per year, and some cover eyeglasses or contact lenses up to a set dollar amount — often $100 to $200 per year. Coverage varies widely by plan and by region, so you cannot assume your plan includes it.

To find out what your plan covers, call the member services number on the back of your insurance card or log into your plan's website. Ask specifically: Does the plan cover routine eye exams? How often? Do you cover eyeglasses or contacts, and if so, how much? Is there a copay or coinsurance? Do I need to see a provider in the plan's network?

If your current Advantage plan does not cover vision and you want it to, you can switch to a plan that does during the Annual Enrollment Period (October 15 to December 7 each year). Plans that include vision coverage often charge a higher monthly premium, so compare the cost of the premium against what you would spend on glasses or exams on your own.

How to find a Medicare-accepting eye doctor

You do not need a referral to see an eye doctor under Medicare. You can see any ophthalmologist or optometrist who accepts Medicare assignment, which means they agree to accept Medicare's approved amount as full payment (after your deductible and coinsurance).

To find a doctor near you, use the Medicare Provider Search tool at Medicare.gov. Go to the "Care Providers" section, select "Ophthalmologist" or "Optometrist," enter your zip code, and filter by those who accept Medicare. You can also call your local health department or ask your primary care doctor for a referral to someone they trust.

Before you schedule, confirm that the doctor accepts Medicare assignment and ask whether the visit will be coded as routine or medical. If you have a Medicare Advantage plan, check whether the doctor is in your plan's network — seeing an out-of-network provider may cost you more.

What to bring to your eye exam

Bring your Medicare card and any other insurance card you have (such as a Medigap or Advantage plan card). Bring a list of all medications and supplements you take, because some affect vision or interact with dilating drops. If you have had eye surgery or a serious eye condition, bring records from your previous eye doctor if you have them.

Wear comfortable clothing and plan to have your pupils dilated, which means your vision will be blurry for a few hours afterward. Do not drive when ready after the exam if your eyes are dilated. Bring sunglasses or ask the office for a pair, because your eyes will be sensitive to light.

Understanding the bill after your eye exam

After your exam, you will receive an Explanation of Benefits (EOB) from Medicare. The EOB shows what Medicare approved, what Medicare paid, and what you owe. If the visit was coded as routine and you do not have diabetes or glaucoma, the EOB will show that Medicare denied the claim and you are responsible for the full bill.

If you believe the visit should have been covered because you have a medical eye condition, contact your eye doctor's office and ask them to review the coding. Sometimes a visit is miscoded, and the office can resubmit it with the correct diagnosis code. Keep a copy of your EOB and any bills you receive.

If you have a Medigap plan (supplemental insurance), it may cover some or all of your coinsurance and deductible. Check your Medigap policy or call your Medigap insurer to ask what vision-related costs they cover.

Frequently Asked Questions

Does Medicare cover eye exams for cataracts?

Yes. If your eye doctor suspects or diagnoses a cataract, the exam is covered as a medical visit. Medicare also covers cataract surgery and one pair of glasses or contacts after surgery. Routine exams to check for cataracts are not covered unless you have diabetes or glaucoma.

Can I get a free eye exam through Medicare?

Not exactly. If you have diabetes or glaucoma, Medicare covers 80 percent of the exam cost after your deductible, so you pay 20 percent (usually $20 to $50). For any other reason, you pay the full cost. Some community health centers offer low-cost or sliding-scale eye exams if cost is a barrier.

What if I need new glasses but Medicare won't cover the exam?

You can pay out of pocket for the exam and glasses. Many optometrists and online retailers offer discounts for seniors. Some community health centers and nonprofit organizations offer low-cost frames and exams. Ask your eye doctor for your prescription and pupillary distance so you can shop around.

Does my Medicare Advantage plan cover routine eye exams?

Many do, but not all. Call your plan's member services number or check your plan documents to find out. Coverage varies by plan and region. If your plan does not cover vision and you want it to, you can switch during the Annual Enrollment Period (October 15 to December 7).

Will Medicare cover my eye exam if I have glaucoma?

Yes. Medicare covers one dilated eye exam every 24 months for people with glaucoma. You pay 20 percent coinsurance after your Part B deductible. If you need more frequent exams because your glaucoma is being monitored closely, ask your doctor whether Medicare will cover additional visits as medically necessary.
