Medicare covers cataract surgery as a medically necessary procedure

Medicare Part B covers the surgery itself when a doctor determines that cataracts are affecting your vision enough to interfere with daily activities. The surgery is performed in an outpatient facility, and Medicare pays 80% of the approved amount after you meet your Part B deductible. You pay the remaining 20%, plus any costs above what Medicare considers reasonable.

The coverage includes the surgeon's fee, the facility cost, and basic anesthesia. It does not include the intraocular lens (the artificial lens implanted during surgery) if you choose a premium lens with special features — though Medicare does cover a standard monofocal lens at no extra charge to you.

Your actual out-of-pocket cost depends on whether you have a Medigap policy, a Medicare Advantage plan, or original Medicare alone. If you have not yet met your Part B deductible for the year, you will pay that first.

Key Takeaways

  • Medicare Part B covers cataract surgery when your doctor documents that cataracts are reducing your vision and affecting your ability to function.
  • You pay 20% of the Medicare-approved cost after your Part B deductible, unless you have a Medigap or Medicare Advantage plan that covers more.
  • A standard monofocal lens implant is included in Medicare coverage at no extra charge; premium lenses cost more and are your responsibility.
  • Pre-surgery testing, the surgery itself, and basic post-operative care are all covered, but you should confirm your specific plan's coverage before scheduling.

What is covered and what is not

Medicare covers the full surgical procedure: the removal of the clouded lens, insertion of an intraocular lens, and the facility where the surgery takes place. Pre-operative testing — such as measurements of your eye and imaging — is covered. Post-operative visits to check your healing are covered. Prescription eyedrops you use after surgery are covered under Part B.

Medicare does not cover the cost difference if you choose a premium lens designed to correct astigmatism or provide multifocal vision (so you can see at multiple distances without glasses). If you select a premium lens, you pay the difference between what the standard lens costs and what the premium lens costs. This difference is typically $500 to $3,000 per eye, depending on the lens type and your surgeon's pricing.

Routine eyeglasses or contact lenses you may need after surgery are not covered by Medicare Part B. However, Medicare Part B does cover one pair of glasses or contact lenses after cataract surgery — but only if the surgery was on both eyes, and only once per lifetime. You must obtain them from a Medicare-approved supplier.

How much you will pay out of pocket

Your cost depends on your coverage type. With original Medicare, you pay your Part B deductible (currently $240 per year, though this amount changes annually) plus 20% of the Medicare-approved amount for the surgery. For a straightforward cataract surgery, the 20% coinsurance typically ranges from $300 to $600 per eye, but this varies by region and facility.

If you have a Medigap policy (supplemental insurance), your plan may cover some or all of the 20% coinsurance and the deductible, depending on which Medigap plan you hold. Plans G, N, and F offer the most comprehensive coverage of these costs. If you have a Medicare Advantage plan, your costs depend on your specific plan — some cover cataract surgery with a copay (often $0 to $250), while others use coinsurance like original Medicare.

If you choose a premium lens, add the lens upgrade cost to your other out-of-pocket expenses. This is a separate charge not subject to the deductible or coinsurance calculation.

How to confirm coverage before surgery

Contact your eye doctor's office and ask them to verify your Medicare coverage before you schedule surgery. They can submit a request to Medicare to confirm that your cataracts meet the medical necessity threshold — this is called a pre-authorization or pre-information. The office will tell you what Medicare will cover and what you will owe.

Call Medicare directly at 1-800-MEDICARE (1-800-633-4227) if you want to verify on your own. Have your Medicare card ready. Ask specifically whether your surgery is covered, what your deductible status is for the year, and whether you have met it. If you have a Medigap or Medicare Advantage plan, also contact that plan to learn what they cover beyond Medicare.

Do not assume that because you have cataracts, the surgery is automatically covered. Medicare requires that your cataracts be reducing your vision in a way that affects your daily life — not just that they exist. Your doctor's documentation of this is what Medicare reviews.

What happens if you have both eyes done

Medicare covers surgery on both eyes, but typically not on the same day. Most surgeons perform one eye first, allow it to heal for a few weeks, and then operate on the second eye. You will meet your Part B deductible once per calendar year, so if both surgeries happen in the same year, you pay the deductible only once and then 20% coinsurance for each eye.

If your surgeries fall in two different calendar years, you will pay the deductible in each year. For example, if you have surgery in December and the second eye in January, you pay the deductible twice.

The one pair of eyeglasses or contacts that Medicare covers after cataract surgery is a one-time benefit for both eyes combined, not per eye. You receive this benefit only once in your lifetime under Medicare Part B.

Medicare Advantage plans and cataract surgery

If you are enrolled in a Medicare Advantage plan (Part C), your coverage for cataract surgery is determined by your specific plan, not by original Medicare rules. Most Medicare Advantage plans do cover cataract surgery, but the copay, coinsurance, or deductible may differ from original Medicare.

Some Medicare Advantage plans cover the surgery with a $0 copay; others charge $100 to $250. Some use coinsurance (you pay a percentage) instead of a fixed copay. A few plans may require prior authorization from the plan before you schedule surgery, meaning your doctor must get approval first.

Contact your Medicare Advantage plan before scheduling to learn your exact cost. Ask whether the plan covers premium lens upgrades or whether you pay the full difference yourself. Plans vary widely, so do not assume your neighbor's plan works the same way yours does.

What to ask your doctor and Medicare

Ask your eye doctor these questions: Does Medicare cover my cataract surgery based on my vision loss? What is the standard lens option that Medicare covers? What are the premium lens options, and what do they cost? Will your office handle the pre-authorization with Medicare, or do I need to do it? What is your facility's charge for the surgery, and what portion will Medicare cover?

Ask Medicare or your plan: Have I met my Part B deductible this year? What is my coinsurance responsibility? If I choose a premium lens, do you cover any of the upgrade cost? Do I need prior authorization before scheduling?

Ask yourself: Can I afford the 20% coinsurance plus any premium lens cost? Do I want to explore Medigap coverage if I do not have it? Would a Medicare Advantage plan with lower copays be better for me if I am switching plans during open enrollment?

Frequently Asked Questions

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

No. Medicare covers cataract surgery only when cataracts are reducing your vision enough to interfere with your daily activities — such as driving, reading, or watching television. If your cataracts are present but not yet affecting your vision significantly, Medicare will not cover the surgery. Your doctor documents the vision loss, and Medicare reviews this before approving coverage.

What if I choose a premium lens and then change my mind?

You must decide on the lens type before surgery. Once the surgery is complete, you cannot switch to a premium lens or request a refund if you chose one. Discuss all lens options with your surgeon during your pre-operative visit and ask about the costs and benefits of each before committing.

Do I need to use a Medicare-approved surgeon?

Your surgeon does not need special Medicare approval to perform cataract surgery, but the facility where the surgery takes place must be Medicare-certified. Most hospitals and ambulatory surgery centers are certified. Ask your surgeon's office whether the facility is Medicare-approved before scheduling.

Can I have cataract surgery at an urgent care or retail clinic?

No. Cataract surgery must be performed in a hospital or an ambulatory surgery center certified by Medicare. Urgent care clinics and retail eye clinics cannot perform this surgery. Your eye doctor will refer you to an appropriate facility if surgery is needed.

What if my cataract surgery is deemed not medically necessary?

If Medicare denies coverage, you have the right to appeal. Ask your doctor's office to submit additional documentation of your vision loss and how it affects your daily life. You can also file an appeal with Medicare yourself within 180 days of the denial notice. Contact 1-800-MEDICARE for instructions on the appeal process.
