Medicare covers some eye care, but not all of it — and the coverage depends on whether you have a medical eye condition or just need glasses

Medicare Part B covers eye exams only when they are medically necessary — meaning a doctor suspects you have an eye disease like glaucoma, cataracts, diabetic retinopathy, or age-related macular degeneration. If you are having the exam to check your vision for glasses or contacts, Medicare does not pay for it. The exam itself is covered at 80 percent after you meet your Part B deductible, but the cost of glasses, contact lenses, or frames is never covered by Original Medicare.

If you have a Medicare Advantage plan (Part C), coverage varies by plan. Some plans include routine eye exams and even a small allowance toward glasses or contacts. You will need to check your specific plan's coverage details, because they differ widely.

Key Takeaways

  • Medicare Part B covers eye exams only when a doctor suspects an eye disease, not for routine vision checks or to get a glasses prescription.
  • You pay 20 percent of the exam cost after meeting your Part B deductible; Medicare pays 80 percent.
  • Glasses, contact lenses, and frames are never covered by Original Medicare, even after a medically necessary exam.
  • Medicare Advantage plans may include routine eye exams and vision benefits, so check your plan documents to see what yours covers.
  • Cataract surgery is covered by Medicare Part B when medically necessary, but you pay 20 percent of the cost after your deductible.

What Medicare Part B Covers for Eye Care

Medicare Part B covers an eye exam performed by an ophthalmologist or optometrist when there is a medical reason — a doctor suspects glaucoma, cataracts, macular degeneration, diabetic eye disease, or another condition affecting the eye itself. The exam is covered at 80 percent after you have met your annual Part B deductible (which is $240 in 2024, though this amount can change yearly).

The key word is medically necessary. If you go in for an exam because you want to update your glasses prescription or you think you might need reading glasses, that exam is not covered. You would pay the full cost out of pocket. The difference matters: a medical eye exam looks for disease; a routine vision exam checks how well you see.

If the exam finds a condition that needs treatment — such as cataracts that are affecting your vision — surgery to remove the cataract is covered by Medicare Part B. You pay 20 percent of the surgeon's fee after your deductible. Lens implants placed during cataract surgery are also covered.

What Medicare Does Not Cover

Original Medicare (Part A and Part B combined) does not cover glasses, contact lenses, or frames under any circumstance. Even if your eye exam was medically necessary and fully covered, the prescription you receive is yours to fill at an optical shop at your own cost. This is true whether the exam found a disease or straightforward revealed that you need correction.

Routine eye exams — exams done to check your vision or update a glasses prescription when there is no suspected disease — are not covered. Many people have these exams annually or every two years. If you want one, you pay the full cost.

Routine care for conditions like dry eye, presbyopia (age-related difficulty focusing), or straightforward refractive errors (nearsightedness, farsightedness, astigmatism) is not covered unless the condition is part of a disease process. For example, dry eye caused by Sjögren's syndrome might be covered as part of treating that disease, but dry eye alone is not.

How Medicare Advantage Plans Handle Vision Coverage

If you have a Medicare Advantage plan (Part C), your vision coverage depends entirely on the plan you chose. Some plans include routine eye exams at no cost or a small copay. Others offer a small allowance — often $100 to $200 per year — toward glasses or contacts. A few plans cover neither.

To find out what your plan covers, look at your plan's Summary of Benefits and Coverage document, which you received when you enrolled. You can also call the plan's customer service number (on your insurance card) and ask specifically: "Does my plan cover routine eye exams?" and "Does my plan help pay for glasses or contacts?" Write down the answers and any limits — for example, "one exam per year" or "up to $150 toward frames."

If you are thinking about switching plans during the annual enrollment period (October 15 to December 7), vision coverage can be one factor to weigh. Plans that include vision benefits often have slightly higher monthly premiums, so compare the premium cost against what you actually spend on eye care each year.

Cataract Surgery and Other Surgical Procedures

Cataract surgery is covered by Medicare Part B when the cataract is affecting your vision enough that surgery is medically necessary. You pay 20 percent of the approved amount after you meet your Part B deductible. The intraocular lens (the artificial lens placed in your eye during surgery) is covered as part of the procedure.

Other eye surgeries — such as surgery for retinal detachment, glaucoma surgery, or corneal transplant — are covered by Medicare Part B when medically necessary, following the same 80/20 split after your deductible.

Refractive surgery (LASIK or PRK) to correct vision is not covered by Medicare. These procedures are considered elective and are paid entirely out of pocket.

How to Know If Your Eye Exam Will Be Covered

Before you schedule an eye exam, ask the eye doctor's office whether they accept Medicare and whether they believe the exam will be medically necessary. If you have symptoms — blurred vision, eye pain, flashing lights, floaters, or a family history of glaucoma — mention them when you call. The office staff can often tell you whether Medicare is likely to cover it.

When you arrive for the exam, bring your Medicare card. The doctor will document the reason for the visit in your medical record. If the exam is medically necessary, the office will bill Medicare. If it is routine, they will ask you to pay out of pocket before or after the visit.

After the exam, you will receive an Explanation of Benefits (EOB) from Medicare showing what was covered and what you owe. If you disagree with the decision, you have the right to appeal, though this process takes time.

Low-Cost Vision Care Options If Medicare Does Not Cover Your Exam

If you need a routine eye exam or glasses and Medicare does not cover it, several programs offer reduced-cost vision care. The EyeCare America program, run by the American Academy of Ophthalmology, provides free or low-cost exams to uninsured and underinsured seniors in some areas. You can search for participating doctors on their website.

Many community health centers and federally may have access to health centers (FQHCs) offer eye exams on a sliding fee scale based on income. You can find one near you through the Health Resources and Services Administration (HRSA) website or by calling 211.

Some optometry and ophthalmology schools offer discounted exams performed by students under supervision. Costco, Walmart, and other retailers with optical departments often have lower prices for glasses and exams than independent optical shops, though they do not accept Medicare.

Frequently Asked Questions

Will Medicare cover my annual eye exam if I have diabetes?

Only if the exam is to check for diabetic retinopathy or other eye disease caused by diabetes. If you are going in for a routine vision check or glasses update, it is not covered. However, if your doctor suspects diabetic eye disease, the exam is covered at 80 percent after your deductible.

Do I need a referral from my primary care doctor to get an eye exam covered by Medicare?

No. You can see an ophthalmologist or optometrist directly without a referral. However, your primary care doctor can refer you if they suspect an eye problem, which may help establish that the exam is medically necessary.

If my eye exam is covered by Medicare, does that mean my glasses will be covered too?

No. Medicare covers the exam itself but never covers glasses, contacts, or frames, regardless of the reason for the exam. You pay the full cost of any vision correction out of pocket.

What happens if I get an eye exam and Medicare decides it was not medically necessary?

You will receive a notice explaining the decision. You may owe the full cost of the exam. You have the right to appeal the decision within 120 days by submitting a written request to Medicare, though the process can take several weeks.

Are there any eye conditions that Medicare covers treatment for but not the exam?

Yes. For example, if you have glaucoma and your doctor prescribes eye drops, the drops are covered by Medicare Part D (prescription drug coverage) if you have it. But the initial exam to diagnose glaucoma must be medically necessary to be covered by Part B.
