Medicare Part B covers cataract removal surgery, including laser-assisted procedures, when a doctor determines the cataract is affecting your vision enough to interfere with daily life
Medicare Part B pays for the surgeon's fee, the facility cost, and the laser equipment used during cataract surgery. You pay 20 percent of the Medicare-approved amount after you meet your Part B deductible for the year. The exact out-of-pocket cost depends on which surgeon and surgical center you use, because Medicare pays based on a set fee schedule, and providers can charge differently.
The surgery itself — whether traditional phacoemulsification or femtosecond laser-assisted cataract surgery (FLACS) — is covered the same way. What matters to Medicare is that a doctor has documented that the cataract is reducing your vision enough to limit your normal activities. If you have cataracts in both eyes, Medicare covers surgery on each eye separately.
Key Takeaways
- Medicare Part B covers the surgeon's fee, facility, and laser equipment for cataract removal when vision loss affects your daily activities.
- You pay 20 percent of the Medicare-approved amount after meeting your Part B deductible; the total out-of-pocket cost varies by provider.
- Your doctor must document that the cataract is reducing your vision enough to interfere with normal tasks before surgery is covered.
- Premium intraocular lenses (IOLs) that correct astigmatism or presbyopia are not covered; you pay the difference between the standard lens and the premium option.
- You should ask your surgeon's office what the expected out-of-pocket cost will be before scheduling, because it depends on the specific Medicare-approved amount for your area.
What Medicare Part B actually pays for
Medicare Part B covers the removal of the clouded lens and the insertion of a standard intraocular lens (IOL) — the artificial lens that replaces your natural one. The laser itself, whether used to soften the cataract before removal or to create the incision, is included in the surgery cost that Medicare reimburses.
The covered amount is based on the Medicare Physician Fee Schedule, which sets a standard reimbursement for cataract surgery in your geographic area. Your surgeon's office bills Medicare directly, and Medicare pays 80 percent of that approved amount. You are responsible for the remaining 20 percent, plus any amount above the approved fee if your surgeon chooses to charge more (though many surgeons accept Medicare's approved amount as payment in full).
What you pay out of pocket
Your actual cost depends on three things: whether you have met your Part B deductible for the year, what the Medicare-approved amount is in your area, and whether your surgeon accepts Medicare assignment (agrees to accept Medicare's approved amount as full payment).
If you have not yet met your Part B deductible, you pay the full deductible amount first, then 20 percent of the approved surgery cost. If you have already met it, you pay only the 20 percent. The Part B deductible is the same every year, but the approved surgery amount varies by location. Call your surgeon's office and ask them to tell you the Medicare-approved amount for cataract surgery in your area, then calculate 20 percent of that number to get a rough estimate.
Some surgical centers charge facility fees on top of the surgeon's fee. Both are covered by Medicare, but you will owe 20 percent of both amounts combined. Ask the facility what their Medicare-approved facility fee is so you can add it to the surgeon's fee when calculating your share.
Premium lenses and add-on features you pay for separately
Medicare covers only a standard monofocal IOL — a single-vision lens that typically corrects distance vision. If you want a premium lens that corrects astigmatism, presbyopia (age-related focusing difficulty), or both, you pay the full difference between the standard lens cost and the premium lens cost out of your own pocket.
The standard lens is usually included in the surgery cost Medicare covers. A toric IOL (for astigmatism) or a multifocal IOL (for presbyopia) can cost anywhere from a few hundred to several thousand dollars more, depending on the lens type and your surgeon. Ask your surgeon's office for the exact price of any premium lens you are considering before you decide.
Laser-assisted cataract surgery (FLACS) itself is covered by Medicare at the same rate as traditional phacoemulsification. Some surgeons charge an additional fee for the laser technology, but this is not standard and should be disclosed to you upfront. If a surgeon quotes you an extra fee for using the laser, ask whether that fee is covered by Medicare or whether it is an out-of-pocket charge.
How to find out your exact cost before surgery
Contact your surgeon's office and ask for a cost estimate. Provide them with your Medicare information, and ask them to tell you:
- The Medicare-approved amount for cataract surgery in your area
- The facility fee (if surgery is at an outpatient surgical center)
- Your expected 20 percent coinsurance amount
- Whether any premium lens or add-on technology carries an extra charge
- Whether the surgeon accepts Medicare assignment
If you have not met your Part B deductible for the year, add that amount to your coinsurance. The surgeon's office should be able to give you a reasonably accurate estimate within a day or two.
What happens if your vision is not bad enough yet
Medicare requires that your cataract be affecting your vision enough to interfere with your normal activities. If your eye doctor says you have a cataract but your vision is still good enough for daily tasks, Medicare will not cover the surgery yet. This is a clinical judgment call, not a specific number on an eye chart.
Your doctor documents the reason for surgery in your medical record. If you later have surgery and Medicare reviews the claim, they check that documentation to confirm the cataract was affecting your function. If the documentation is weak or missing, Medicare may deny the claim and you could be billed for the full cost.
If you are unsure whether your cataract is advanced enough, ask your eye doctor directly: "Does Medicare consider this cataract advanced enough that they would cover surgery?" A good eye doctor will tell you honestly whether you are at the point where surgery is medically necessary or whether you can wait.
Cataract surgery at an ambulatory surgical center versus a hospital
Cataract surgery is usually done at an outpatient surgical center, not a hospital. Medicare covers the facility fee at either location, but the cost structure is slightly different. At an ambulatory surgical center, you typically pay a facility fee plus the surgeon's fee. At a hospital outpatient department, you may pay a facility fee plus the surgeon's fee, but the hospital's charges can be higher.
Ask your surgeon where the surgery will be performed and request the facility fee for that location. If you have a choice between locations, comparing the facility fees can help you understand the total cost difference.
Frequently Asked Questions
Does Medicare cover cataract surgery in both eyes at the same time?
Medicare covers cataract removal in each eye, but surgeons typically operate on one eye at a time, usually waiting one to two weeks between surgeries. This allows your first eye to heal and your vision to stabilize before the second surgery. Both surgeries are covered separately by Medicare.
What if I have a supplemental insurance plan (Medigap)?
Medigap plans vary in what they cover. Most Medigap plans cover some or all of the 20 percent coinsurance you owe after Medicare pays. Contact your Medigap insurer before surgery to find out what they will pay toward cataract surgery, so you know your true out-of-pocket cost.
Does Medicare cover the cost of glasses or contacts after cataract surgery?
Medicare Part B covers one pair of glasses or contact lenses after cataract surgery, but only if you had the surgery covered by Medicare. This benefit is limited to one pair per eye per lifetime. Your eye doctor can provide a prescription after surgery, and you can use it at any optical shop.
What if my surgeon is not in my Medicare network?
Medicare does not use networks the way private insurance does. Any surgeon who accepts Medicare can treat you, and Medicare pays the same approved amount regardless of whether the surgeon is "in network." However, some surgeons may not accept Medicare assignment, meaning they can charge you more than Medicare's approved amount. Always ask whether your surgeon accepts Medicare assignment before scheduling.
Will Medicare cover cataract surgery if I also have other eye conditions?
Yes. If you have glaucoma, macular degeneration, or another eye condition along with a cataract, Medicare still covers the cataract surgery based on the same rules. The other condition does not change your coverage, though your surgeon may recommend treating the other condition before or after cataract surgery depending on your situation.
