Medicare covers one diabetic eye exam per year at no cost to you

If you have Medicare Part B and a diagnosis of diabetes, you are covered for one comprehensive dilated eye exam each year to check for diabetic retinopathy — damage to the blood vessels in your retina caused by high blood sugar. Medicare pays for the full exam, and you pay nothing if your eye doctor accepts Medicare assignment (which most do). The exam includes dilating your pupils so the doctor can see the back of your eye clearly.

This coverage is separate from your regular vision benefits. Even if you have a vision plan through a Medigap or Medicare Advantage plan, Medicare Part B still covers this one annual diabetic eye exam. The key requirement is that your doctor has documented that you have diabetes — either Type 1 or Type 2.

Key Takeaways

  • Medicare Part B covers one dilated eye exam per year for people with diabetes, with no out-of-pocket cost if your eye doctor accepts Medicare assignment.
  • The exam must be performed by an ophthalmologist or optometrist and must include dilation to check for diabetic retinopathy.
  • Your doctor must have a record that you have diabetes for the claim to be covered under this benefit.
  • If you need more than one exam per year, you may have to pay out of pocket unless your eye doctor finds a medical reason for additional visits.

Who performs the exam and where to go

An ophthalmologist (a medical doctor who specializes in eye care) or an optometrist (a licensed eye care professional) can perform your covered diabetic eye exam. Both are trained to detect diabetic retinopathy and other eye problems related to diabetes. You can see either type of provider — the coverage is the same.

Before you schedule, call the office and confirm that the provider accepts Medicare assignment. This means they have agreed to accept Medicare's payment as full payment and will not bill you extra. Most eye care offices accept Medicare, but it is worth checking. If a provider does not accept assignment, you may end up paying more out of pocket.

What the exam includes

Your diabetic eye exam will include a dilated eye test, which means your eye doctor will put drops in your eyes to widen your pupils. This allows them to see the back of your eye and check for signs of diabetic retinopathy, such as leaking blood vessels, swelling, or damage to the retina. The exam also checks for other eye problems common in people with diabetes, including cataracts and glaucoma.

The exam typically takes 30 to 60 minutes. Your vision will be blurry for a few hours afterward because of the dilating drops, so plan to have someone drive you home or use another form of transportation. Bring sunglasses — your eyes will be sensitive to light.

When you may have to pay out of pocket

Medicare covers one dilated exam per year. If you need a second exam in the same year, you will likely have to pay for it yourself unless your eye doctor documents a medical reason — for example, if they find signs of diabetic retinopathy that require monitoring before your next annual exam. In that case, the additional visit may be covered, but you should ask your doctor's office to check with Medicare before the visit.

You will also pay out of pocket for glasses, contact lenses, or other vision correction products, even if they are prescribed during your covered exam. These items are not included in Medicare Part B coverage. Some Medicare Advantage plans or Medigap policies may cover vision correction, so check your plan documents.

How to schedule your exam

Call an eye care office in your area and tell them you have Medicare and want to schedule your annual diabetic eye exam. Have your Medicare card ready. The office will verify your coverage and confirm that they accept Medicare assignment. Let them know you have diabetes so they can note it in your chart — this ensures the claim is processed under the correct benefit.

If you do not have a regular eye doctor, you can search for one using the Medicare Provider Search tool on Medicare.gov, or ask your primary care doctor for a referral. You can also call your state's health department or a local diabetes organization for recommendations.

What happens if you do not have Part B

If you have Original Medicare Part A only (hospital insurance) but not Part B (medical insurance), you are not covered for diabetic eye exams. Part B is what covers outpatient care, including eye exams. If you declined Part B when you first became may be able to access for Medicare, you may be able to enroll during the General Enrollment Period (January 1 to March 31 each year), though a late enrollment penalty may explore.

If you have a Medicare Advantage plan instead of Original Medicare, check your plan documents or call your plan to see what vision coverage is included. Medicare Advantage plans vary in what they cover for eye care, and some may cover more than one exam per year or include vision correction.

What to bring to your appointment

Bring your Medicare card and any photo ID. If you have other insurance (such as a Medigap or Medicare Advantage plan), bring that card too. Bring a list of any eye medications you use and any other health conditions you have, especially if they affect your eyes. If you have had previous eye exams, ask if those records can be sent to your new provider so they can compare and track changes over time.

Wear comfortable clothing and plan to have someone available to drive you home if possible, since your vision will be blurred after the dilating drops.

Frequently Asked Questions

Do I need a referral from my doctor to get a diabetic eye exam?

No, you do not need a referral. You can call an eye care office directly and schedule your exam. However, if you do not have a regular eye doctor, your primary care doctor can recommend one.

What if I have Medicare Advantage instead of Original Medicare?

Medicare Advantage plans must cover at least the same diabetic eye exam benefit as Original Medicare Part B. However, some plans cover additional vision services or more frequent exams. Check your plan documents or call your plan to see what is included.

Will I have to pay a copay or coinsurance?

No. If your eye doctor accepts Medicare assignment, you pay nothing for the covered diabetic eye exam. Medicare pays the full cost. If the doctor does not accept assignment, you may owe a balance.

What if my eye doctor finds diabetic retinopathy?

Your doctor will discuss treatment options with you. Depending on the severity, you may need laser treatment, injections, or surgery. These treatments are covered by Medicare Part B. Your doctor may also recommend more frequent eye exams, which Medicare may cover if medically necessary.

Can I get my exam at a retail vision center like Walmart or Costco?

Yes, if the optometrist or ophthalmologist at that location accepts Medicare assignment. Call ahead to confirm. Many retail vision centers do accept Medicare, but coverage and acceptance vary by location.
