Medicare covers cataract surgery, but only the surgical procedure itself

Medicare Part B covers cataract surgery when your doctor determines it is medically necessary — meaning the cataract is affecting your vision enough to interfere with daily life. The surgery itself, the intraocular lens implant, and related facility costs are covered. You pay 20% of the Medicare-approved amount after you meet your Part B deductible, which is $240 in 2024.

What Medicare does not cover is the cost of premium lens options. If you choose a lens that corrects astigmatism, presbyopia, or distance vision beyond what a standard lens does, you pay the full difference out of pocket. That difference can range from a few hundred to several thousand dollars per eye, depending on the lens technology.

The surgery itself is typically an outpatient procedure, meaning you go home the same day. Your eye doctor (either an ophthalmologist or optometrist) must refer you to a surgeon, and the surgeon's office will handle the Medicare paperwork.

Key Takeaways

  • Medicare Part B covers the surgical removal of a cataract and the cost of a standard intraocular lens implant when medically necessary.
  • You pay 20% of the Medicare-approved surgical cost after meeting your $240 Part B deductible for the year.
  • Premium lens upgrades that correct astigmatism or reduce dependence on glasses are not covered and cost extra out of pocket.
  • Your eye doctor must document that the cataract is affecting your vision before Medicare will cover the procedure.
  • Medigap or Medicare Advantage plans may cover some or all of your 20% coinsurance, depending on your specific plan.

How Medicare determines if your cataract surgery is medically necessary

Medicare requires your eye doctor to show that the cataract is causing vision loss that affects your ability to perform everyday tasks. straightforward having a cataract does not automatically mean surgery is covered — the cataract must be the reason your vision is poor.

Your eye doctor will perform a visual acuity test and document your vision level in your medical record. They will also note how the cataract is affecting activities like reading, driving, or watching television. If your vision is 20/40 or worse in the affected eye and the cataract is the cause, Medicare will typically cover the surgery.

If you have other eye conditions — such as macular degeneration or diabetic retinopathy — that are also affecting your vision, your doctor must clarify that removing the cataract will meaningfully improve your sight. Medicare will not cover surgery if another condition is the main cause of your vision loss.

What you pay out of pocket for cataract surgery

Your costs depend on whether you have Original Medicare alone, a Medigap plan, or a Medicare Advantage plan.

With Original Medicare only: You pay your Part B deductible ($240 in 2024) plus 20% of the Medicare-approved amount for the surgery and facility. For a straightforward cataract removal with a standard lens, your total out-of-pocket cost is typically $300 to $600 per eye, though this varies by region and surgeon.

With a Medigap plan: Most Medigap plans (Plan C, D, F, G, M, and N) cover the 20% coinsurance, so you would pay only the deductible or nothing, depending on your plan. Check your Medigap policy documents to confirm what your plan covers.

With a Medicare Advantage plan: Your costs depend on your specific plan's copay or coinsurance structure. Some plans cover cataract surgery with a small copay; others require coinsurance. Call your plan to find out your exact cost before scheduling surgery.

Premium lens options and their costs

A standard intraocular lens corrects distance vision only. If you want to reduce your dependence on glasses after surgery, you have options — but Medicare does not cover the extra cost.

Multifocal lenses allow you to see at multiple distances (near, intermediate, and far) without glasses. The upgrade cost is typically $1,500 to $3,000 per eye.

Toric lenses correct astigmatism at the same time as removing the cataract. The upgrade cost is usually $1,000 to $2,500 per eye.

Extended depth-of-focus lenses provide a wider range of clear vision than standard lenses. The upgrade cost is typically $1,500 to $3,500 per eye.

Some surgeons offer financing plans for premium lenses, and some Medigap or Medicare Advantage plans may cover a portion of the upgrade cost. Ask your surgeon's office what payment options are available and whether your supplemental insurance covers any part of the premium lens cost.

How to prepare for cataract surgery and Medicare coverage

Start by scheduling an eye exam with your eye doctor. Bring your Medicare card. Your doctor will test your vision and examine your eye to determine whether the cataract is affecting your sight enough for Medicare to cover surgery.

If your doctor recommends surgery, ask them to document the medical reason in your chart. This documentation is what Medicare uses to decide whether to cover the procedure. Your doctor's office will submit the claim to Medicare on your behalf.

Before the surgery date, contact your Medicare Advantage plan or Medigap insurer to confirm your out-of-pocket costs. Ask whether your plan covers any premium lens upgrades. If you are considering a premium lens, get a written quote from the surgeon's office showing the standard lens cost and the upgrade cost separately.

On the day of surgery, bring your Medicare card and any insurance cards for supplemental coverage. The surgeon's office will have you sign consent forms that include the lens choice and any premium upgrades you have decided on.

What happens if Medicare denies coverage

Medicare may deny coverage if your eye doctor does not document that the cataract is causing vision loss, or if your vision loss is caused by another eye condition rather than the cataract.

If your claim is denied, you have the right to request a review. Your surgeon's office can help you file an appeal and provide additional documentation of your vision loss. The appeal process typically takes 30 to 60 days.

If you disagree with the appeal decision, you can request a hearing before a Medicare administrative law judge. This step is less common but is available if you believe Medicare made an error.

Cataract surgery in both eyes

If you have cataracts in both eyes, Medicare covers surgery on each eye separately. Your surgeon will typically schedule the second eye surgery a few weeks after the first, once your first eye has healed.

You will pay the Part B deductible only once per calendar year, so your second surgery will cost less out of pocket than your first (assuming both surgeries happen in the same year). If your surgeries fall in different calendar years, you will pay the deductible twice.

If you choose a premium lens for one eye, you can choose a different lens type for the other eye, or stick with a standard lens. The cost of each eye is separate.

Frequently Asked Questions

Does Medicare cover the eye exam before cataract surgery?

Yes. Medicare Part B covers one routine eye exam per year performed by an ophthalmologist or optometrist. If your eye doctor needs to do additional testing to evaluate your cataract, those tests are also covered. You pay 20% coinsurance after your deductible.

What if I have a Medicare Advantage plan instead of Original Medicare?

Medicare Advantage plans must cover cataract surgery the same way Original Medicare does, but your out-of-pocket costs may be different. Call your plan to find out your copay or coinsurance before scheduling surgery. Some plans require prior approval from the plan before surgery.

Can I choose which eye surgeon performs my cataract surgery?

Yes, but if you have a Medicare Advantage plan, the surgeon must be in your plan's network. If you have Original Medicare, you can see any surgeon who accepts Medicare. Ask your eye doctor for a referral, or search the Medicare provider directory at Medicare.gov to find surgeons near you.

Will I need glasses after cataract surgery with a standard lens?

Most people need glasses for reading or close work after surgery with a standard lens, even if they did not wear glasses before the cataract developed. Your surgeon will discuss what to expect during your pre-surgery visit. Premium lenses may reduce or eliminate the need for glasses, but Medicare does not cover the extra cost.

How long does it take to recover from cataract surgery?

Most people notice improved vision within a few days, and vision continues to improve over several weeks. You will need to use prescribed eye drops for several weeks and avoid strenuous activity and water in your eye during healing. Your surgeon will give you detailed aftercare instructions.
