Medicare Part B covers cataract surgery when your doctor says it is medically necessary

Yes, Medicare Part B pays for cataract surgery if your vision loss from cataracts is affecting your daily life and your eye doctor documents that surgery will help. Medicare does not cover the surgery straightforward because you have a cataract — it has to be interfering with your ability to do things you need to do, like reading, driving, or watching television. Your doctor makes this information, not Medicare.

Medicare pays 80 percent of the approved amount for the surgery itself after you meet your Part B deductible (which is $226 in 2024, though this changes yearly). You pay the remaining 20 percent, called coinsurance. If you have a Medigap or Medicare Advantage plan, that plan may cover some or all of your coinsurance, depending on which plan you have.

The surgery typically happens at an outpatient surgical center or hospital. You go home the same day. Medicare covers the surgeon's fee, the facility cost, and the basic intraocular lens (IOL) — the artificial lens placed in your eye during surgery.

Key Takeaways

  • Medicare Part B covers cataract surgery when your eye doctor confirms the cataract is reducing your vision enough to affect daily activities.
  • You pay 20 percent coinsurance after meeting your Part B deductible; the exact amount depends on what your surgeon charges and your location.
  • Medicare covers the standard intraocular lens, but premium lens options cost extra and are your responsibility.
  • Your eye doctor must refer you to a surgeon, and the surgeon's office will verify your Medicare coverage before scheduling.
  • Cataract surgery is outpatient, meaning you return home the same day, and recovery typically takes a few weeks.

What Medicare actually pays for during cataract surgery

Medicare Part B covers the surgeon's fee, the facility where the surgery takes place, anesthesia, and the standard monofocal intraocular lens. The monofocal lens corrects distance vision. It is the basic lens Medicare considers medically necessary.

Medicare does not cover the cost of premium lens options, such as multifocal lenses (which correct both near and distance vision) or toric lenses (which correct astigmatism). If you choose one of these lenses, you pay the full difference out of pocket. This can range from $500 to $3,000 per eye, depending on the lens type and your surgeon's fees. Ask your surgeon's office for the exact cost before surgery.

Pre-surgery testing, such as measurements of your eye and imaging, is covered by Medicare. Post-surgery visits during your recovery period are also covered. If you need glasses or contact lenses after surgery, that cost is yours — Medicare does not cover eyewear.

How to get Medicare approval before surgery

You do not need to call Medicare ahead of time to ask permission. Instead, your eye doctor (usually an ophthalmologist) examines you, documents that the cataract is affecting your vision, and refers you to a surgeon. The surgeon's office contacts Medicare to verify your coverage and confirm that you have met any requirements.

Before your surgery appointment, the surgeon's office will tell you what your out-of-pocket cost will be. This is when you learn your exact coinsurance amount. If you have a Medigap or Medicare Advantage plan, bring your insurance card so the office can calculate what your secondary plan will cover.

If you are enrolled in a Medicare Advantage plan instead of Original Medicare, the process is similar, but you may have different copays or coinsurance amounts. Check your plan documents or call your plan's customer service to learn what you will owe before you schedule surgery.

What happens if both eyes need surgery

Medicare covers surgery on both eyes, but they are typically done separately, usually one to three weeks apart. This allows your first eye to heal and your vision to stabilize before the second surgery. Each surgery is subject to the same 20 percent coinsurance after your deductible.

Because the surgeries are separate procedures, you will meet your Part B deductible twice if both surgeries happen in the same calendar year. However, once you have paid your deductible for the year, you only owe coinsurance for the second surgery. Ask your surgeon's office to schedule both surgeries in the same calendar year if possible, so you understand your total out-of-pocket cost upfront.

Costs you are responsible for

After you meet your $226 Part B deductible (2024 amount), you owe 20 percent of Medicare's approved amount for the surgery. The approved amount varies by location and surgeon, but typically ranges from $3,000 to $4,000 per eye for the surgery and lens combined. This means your coinsurance is usually between $600 and $800 per eye.

If you choose a premium intraocular lens, add $500 to $3,000 per eye to this cost. If you do not have Medigap or Medicare Advantage coverage, you pay this entire amount yourself. If you have Medigap Plan G, Plan F, or Plan C, those plans cover your coinsurance. If you have a Medicare Advantage plan, your coinsurance may be lower, but check your plan documents.

Some surgeons' offices offer payment plans if your out-of-pocket cost is high. Ask about this option when you call to schedule.

When Medicare may deny coverage

Medicare denies cataract surgery coverage in a few situations. The most common is when your eye doctor cannot document that the cataract is affecting your vision enough to interfere with daily activities. If your doctor says "you have a cataract, but your vision is still good," Medicare will not pay.

Medicare may also deny coverage if the surgery is being done at a facility that is not Medicare-approved, though this is rare in the United States. If your surgeon's office is in-network with Medicare, this is not a concern.

If Medicare denies your claim, you have the right to appeal. 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.

What to ask your eye doctor and surgeon

Before you schedule surgery, ask your eye doctor: "Does my cataract meet Medicare's standard for surgery based on my vision loss?" If the answer is yes, ask for a referral to a surgeon who accepts Medicare.

When you call the surgeon's office, ask: "What is my out-of-pocket cost after Medicare pays?" and "Do you offer payment plans?" Ask whether the surgeon uses the standard monofocal lens or offers premium options, and what the cost difference is. If you have a secondary insurance plan, ask the surgeon's office to calculate your total cost with that plan included.

Ask when you can expect to have your vision stabilize after surgery (usually two to four weeks) and when you can resume normal activities like driving and exercise.

Frequently Asked Questions

Does Medicare cover cataract surgery if I have no symptoms yet?

No. Medicare covers cataract surgery only when the cataract is causing vision loss that affects your daily life. If you have a cataract but your vision is still clear, Medicare will not pay for surgery. Your eye doctor will tell you whether your cataract meets this standard.

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 copay or coinsurance amount may be different. Call your plan's customer service number (on your insurance card) and ask what you will owe for cataract surgery. Some Advantage plans have lower coinsurance than the standard 20 percent.

Can I choose which surgeon performs my cataract surgery?

Yes, you can choose any surgeon who accepts Medicare. Your eye doctor can refer you to a surgeon, or you can search for Medicare-approved surgeons in your area on Medicare.gov. Make sure the surgeon operates at a Medicare-approved facility.

Will I need glasses after cataract surgery?

Most people need glasses for reading or close work after cataract surgery, even if they did not wear glasses before. Some people also need glasses for distance vision. Your surgeon will discuss this with you before surgery. Glasses are not covered by Medicare, but they are usually inexpensive.

What if I cannot afford my coinsurance?

Talk to your surgeon's office about payment plans. Some offices work with patients to spread the cost over several months. You can also ask your eye doctor whether delaying surgery is safe, though this is usually not recommended if the cataract is significantly affecting your vision and safety.
