Medicare Part B covers cataract removal when medically necessary

Yes. Medicare Part B pays for cataract removal surgery when your eye doctor determines the cataract is affecting your vision enough to interfere with daily activities. Medicare covers the surgeon's fee, the facility cost, and the anesthesia. You pay 20 percent of the approved amount after you meet your Part B deductible for the year. If your cataract is not yet affecting your vision significantly, Medicare will not cover the surgery.

The surgery itself is usually outpatient — you go home the same day. Medicare covers the procedure whether it is performed at a hospital, an ambulatory surgery center, or an ophthalmologist's office, as long as the facility is Medicare-approved.

Key Takeaways

  • Medicare Part B covers cataract removal when your doctor documents that the cataract reduces your vision enough to limit daily activities.
  • You pay 20 percent of the Medicare-approved cost after meeting your annual Part B deductible, which is $240 in 2024.
  • An intraocular lens implant — the artificial lens placed during surgery — is covered by Medicare at no additional cost.
  • Medicare does not cover the cost of premium lens options, such as multifocal or toric lenses, beyond what a standard lens would cost.
  • You should ask your eye doctor to submit the claim to Medicare before surgery so you know your out-of-pocket cost in advance.

How Medicare determines whether your cataract qualifies

Your ophthalmologist or optometrist must document that the cataract is reducing your vision in a way that affects your ability to perform normal tasks. This is called "visual acuity" testing. Medicare does not have a single cutoff number — the decision depends on your individual circumstances and what activities matter to you.

For example, if you are a driver, a cataract that makes night driving unsafe may may have access to even if your daytime vision is still adequate. If you live alone and need to read medication labels or cook, a cataract affecting your near vision may may have access to. Your doctor will note the specific impact on your daily life in your medical record, and this becomes part of the claim Medicare reviews.

If your cataract is early and not yet affecting your vision meaningfully, your doctor will likely recommend monitoring it rather than surgery. Medicare will not cover surgery in this case, and most insurers will not either.

What you pay out of pocket

Your cost depends on whether you have met your Part B deductible for the calendar year. The Part B deductible is $240 in 2024, though this amount can change annually. Once you meet the deductible, Medicare pays 80 percent of the approved amount and you pay 20 percent.

The approved amount varies by location and by facility type. A surgery center may have a lower approved amount than a hospital. Ask your doctor's office to contact Medicare or check the Medicare website to find the approved amount for your specific procedure and location before you schedule surgery. This lets you calculate your 20 percent cost ahead of time.

If you have a Medigap (supplemental insurance) plan, it may cover some or all of your 20 percent coinsurance. If you have a Medicare Advantage plan, your out-of-pocket costs follow your plan's rules, which may differ from Original Medicare. Check your plan documents or call your plan's member services line to confirm your cost before surgery.

Intraocular lens implants and premium lens options

During cataract removal, your surgeon removes the clouded lens and replaces it with an artificial lens called an intraocular lens (IOL). Medicare covers the cost of a standard monofocal IOL — a lens that corrects distance vision — at no additional charge beyond the surgery cost.

If you choose a premium lens option, such as a multifocal lens (which corrects both distance and near vision) or a toric lens (which corrects astigmatism), Medicare covers only the cost of the standard monofocal lens. You pay the difference out of pocket. This difference can range from a few hundred to several thousand dollars per eye, depending on the lens type and your surgeon's pricing.

Discuss lens options with your surgeon before surgery. Ask for the cost of each option and what Medicare will cover so you can decide whether the premium lens is worth the extra expense to you.

How to prepare your claim before surgery

Ask your eye doctor's office to submit a pre-authorization request to Medicare before your surgery date. This is not required, but it protects you: Medicare will review the request and tell you in writing whether the surgery meets coverage rules and what your estimated out-of-pocket cost will be. This takes about one to two weeks.

Bring to your pre-surgery appointment: your Medicare card, any other insurance cards you have, and a list of current medications. Your doctor's office will use this information to submit the claim. If you have questions about the approved amount or your cost share, ask the office staff to call Medicare on your behalf — they often have direct access to Medicare's billing department and can get answers faster than you can.

After surgery, the facility will submit the claim to Medicare automatically. You will receive an Explanation of Benefits (EOB) in the mail showing what Medicare paid and what you owe. If the amount surprises you, contact Medicare or your doctor's billing office to ask why.

What happens if both eyes need cataract removal

Medicare covers cataract removal on both eyes, but surgeons typically operate on one eye first, wait for it to heal (usually two to four weeks), and then operate on the second eye. This staged approach lets your vision stabilize after the first surgery and gives your brain time to adjust to the new lens.

You will pay your 20 percent coinsurance for each eye separately. If you have not yet met your Part B deductible when the first surgery happens, you will pay the deductible plus 20 percent for that eye. By the time the second eye is done, you will have already met the deductible, so you will pay only 20 percent for the second surgery.

Frequently Asked Questions

Does Medicare cover cataract surgery if I have cataracts in both eyes?

Yes, Medicare covers removal of cataracts in both eyes. Surgeons usually operate on one eye first and the other eye several weeks later. You pay your 20 percent coinsurance for each surgery separately, but you only pay the Part B deductible once per calendar year.

What if my eye doctor says I do not need cataract surgery yet?

If your cataract is not affecting your vision enough to interfere with daily activities, Medicare will not cover surgery. Your doctor will recommend monitoring the cataract with regular eye exams. You can return for surgery later if the cataract worsens and begins to limit your activities.

Do I have to use a specific surgeon or facility for Medicare to cover the cost?

No. Medicare covers cataract removal at any Medicare-approved facility — hospital, surgery center, or ophthalmologist's office. You can choose your surgeon and facility. Confirm that the facility is Medicare-approved before scheduling, and ask about the approved amount so you know your cost share.

Will Medicare cover the cost of a premium lens if my doctor recommends it?

Medicare covers only a standard monofocal lens. If your doctor recommends a premium lens such as multifocal or toric, Medicare pays for the standard lens and you pay the difference out of pocket. Ask your surgeon for the cost of each option before deciding.

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

Medicare Advantage plans cover cataract removal, but your out-of-pocket costs follow your plan's rules, not Original Medicare's rules. Your plan may have a different deductible, copay, or coinsurance. Call your plan's member services number before scheduling surgery to learn what you will pay.
