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

Yes, Medicare Part B covers cataract surgery. The surgery must be performed by an ophthalmologist or optometrist who accepts Medicare, and your doctor must document that the cataract is affecting your vision enough to interfere with daily activities. Medicare does not cover surgery for cataracts that are not yet affecting your sight, even if they are visible on an eye exam.

Part B pays 80 percent of the approved amount after you meet your annual deductible. You pay the remaining 20 percent, plus any difference between what Medicare approves and what your surgeon charges if they do not accept Medicare assignment. The total out-of-pocket cost varies depending on your deductible, your specific surgeon's fees, and whether you have supplemental coverage.

Key Takeaways

  • Medicare Part B covers cataract surgery when a doctor confirms the cataract reduces your vision enough to affect daily life.
  • You pay 20 percent of the Medicare-approved cost after meeting your annual Part B deductible, which is $240 in 2024.
  • Intraocular lens implants (the artificial lens placed during surgery) are covered at no extra charge under Part B.
  • If your surgeon does not accept Medicare assignment, you may owe the full difference between their charge and Medicare's approved amount.
  • Routine eye exams and glasses or contact lenses after surgery are not covered by Part B; you need separate vision coverage for those.

What Part B actually pays for during cataract surgery

Medicare Part B covers the surgery itself, the facility costs (whether performed in a hospital outpatient department or an ambulatory surgery center), and the intraocular lens implant. The intraocular lens is the artificial lens placed in your eye during the procedure to replace the clouded natural lens. Standard monofocal lenses are fully covered. Premium lenses that correct astigmatism or allow you to see at multiple distances without glasses cost extra, and Medicare covers only the standard lens portion.

Pre-operative testing, such as measurements of your eye and blood work, is covered if ordered by your surgeon. Post-operative care visits during the healing period are also covered. However, routine eye exams before surgery and glasses or contact lenses prescribed after surgery are not covered by Part B. You would need a separate vision plan or pay out of pocket for those.

How much you will pay out of pocket

Your costs depend on whether you have met your Part B deductible for the year. The Part B deductible for 2024 is $240. Once you meet it, you pay 20 percent of what Medicare approves for the surgery and related care.

The Medicare-approved amount for cataract surgery varies by location and facility type. In most areas, the approved amount for facility-based surgery ranges from roughly $1,500 to $3,000, meaning your 20 percent share could be $300 to $600 after the deductible. If you choose a premium intraocular lens, you pay the full difference between the premium lens cost and the standard lens cost — typically $500 to $2,000 per eye, depending on the lens type and your surgeon.

If your surgeon does not accept Medicare assignment, they can charge up to 15 percent more than Medicare's approved amount. You would owe that overage in addition to your 20 percent coinsurance. Always confirm your surgeon accepts Medicare assignment before scheduling.

Finding a Medicare-participating surgeon

Search the Medicare Physician Compare tool at compare.cms.gov to find ophthalmologists and optometrists in your area who accept Medicare. The tool shows whether each provider accepts assignment, their location, and their contact information. You can also call your Medicare Advantage plan (if you have one) or your Original Medicare carrier to request a list of in-network eye surgeons.

When you call to schedule, ask the surgeon's office directly whether they accept Medicare assignment. If they do, your costs are limited to the deductible and 20 percent coinsurance. If they do not, ask for an estimate of their total charge so you can compare it to what Medicare approves.

Medicare Advantage plans and cataract surgery

If you have a Medicare Advantage plan (Part C), your coverage for cataract surgery is determined by your specific plan, not by Part B rules. Most Medicare Advantage plans cover cataract surgery, but your out-of-pocket costs, deductibles, and copayments may differ from Original Medicare. Some plans require prior authorization before surgery, meaning your surgeon must get approval from the plan before the procedure is scheduled.

Contact your Medicare Advantage plan directly to learn your coverage details. Ask whether the surgery requires prior authorization, what your copayment or coinsurance will be, and whether your preferred surgeon is in the plan's network. If your surgeon is out of network, your costs will be higher or the plan may not cover the surgery at all.

What happens if you delay surgery

Cataracts worsen over time, and waiting longer usually means thicker, denser cataracts that take longer to remove and carry slightly higher surgical risk. However, Medicare will not cover surgery until the cataract is affecting your vision enough to interfere with your daily activities — reading, driving, watching television, or other tasks you do regularly. Your ophthalmologist will determine when surgery becomes medically necessary based on your vision test results and your own report of how the cataract affects your life.

If you are on a tight budget, discuss the timing with your surgeon. Some people schedule surgery in January to reset their deductible, or they space out surgery on both eyes to spread costs across two calendar years. These are personal decisions, not medical ones, and your surgeon can help you plan around your financial situation.

Supplemental insurance and cataract surgery costs

If you have a Medigap (supplemental) policy, it may cover some or all of your 20 percent coinsurance and deductible. Medigap plans vary in what they cover, so review your policy documents or call your Medigap insurer to confirm. Some Medigap plans cover the full coinsurance; others cover part of it.

If you do not have Medigap and are concerned about costs, ask your surgeon's office about payment plans. Many surgical centers offer financing options that allow you to spread payments over several months with little or no interest. Some community health centers and charitable organizations also offer reduced-cost eye surgery for people with limited income.

Frequently Asked Questions

Does Medicare cover both eyes in one surgery visit?

Yes, Medicare covers surgery on both eyes. However, surgeons typically perform one eye at a time, usually one to two weeks apart, so you can heal from the first eye before the second surgery. Each surgery is billed separately, so you pay your 20 percent coinsurance for each eye.

What if my cataract surgery is done in a hospital instead of an outpatient center?

Medicare covers cataract surgery in a hospital outpatient department the same way it covers surgery in an ambulatory surgery center. You pay the same 20 percent coinsurance after your deductible. Hospital facility fees may be slightly higher than surgery center fees, so your out-of-pocket cost could be a bit more, but coverage rules are identical.

Does Medicare cover the cost of glasses after cataract surgery?

No, Medicare Part B does not cover eyeglasses or contact lenses after cataract surgery. You would need to purchase them separately or have a separate vision plan. Some people find they need only a mild prescription after surgery, especially if they choose a premium intraocular lens.

Can I use my Medicare Advantage plan's out-of-network benefits for cataract surgery?

Most Medicare Advantage plans do not cover out-of-network surgery, or they cover it at a much higher out-of-pocket cost to you. Check your plan's summary of benefits or call the plan to confirm. If your preferred surgeon is out of network and your plan does not cover out-of-network care, you may need to choose an in-network surgeon or switch plans during the annual enrollment period.

What if my doctor says I need a premium lens but I cannot afford it?

Medicare covers the standard monofocal lens at no extra charge. If you cannot afford a premium lens, the standard lens is a fully covered option. Discuss with your surgeon what your vision will be like with a standard lens — many people are satisfied with standard lenses and do not need glasses for most activities after surgery.
