Medicare covers standard cataract surgery, but not the laser version
Medicare Part B covers cataract surgery when your doctor says it is medically necessary — meaning the cataract is affecting your vision enough to interfere with daily life. However, Medicare only pays for the traditional surgical method, in which your surgeon uses a blade and ultrasound to remove the clouded lens. If you choose laser-assisted cataract surgery instead, Medicare will not cover the laser portion of the procedure. You will pay out of pocket for that part, though Medicare may still cover the basic surgery itself.
The difference matters because laser surgery costs more — typically $1,500 to $3,000 extra per eye — and you need to know this cost before you schedule. Your surgeon's office should tell you upfront whether they are recommending traditional surgery (which Medicare covers) or laser surgery (which it does not), and what the out-of-pocket cost would be.
Key Takeaways
- Medicare Part B covers traditional cataract surgery when medically necessary, but does not cover the laser-assisted version of the same procedure.
- You typically pay 20 percent of the Medicare-approved amount for traditional surgery after you meet your Part B deductible, but you pay the full cost of laser technology yourself.
- Your surgeon must document that the cataract is affecting your vision before Medicare will pay, so a vision test is part of the process.
- If you want laser surgery, ask your surgeon's office for the exact out-of-pocket cost before your appointment, because prices vary widely by location and facility.
What Medicare Part B actually covers in cataract surgery
Medicare Part B pays for the surgeon's fee, the facility cost, and the intraocular lens (the artificial lens placed in your eye after the clouded one is removed). It also covers the pre-surgery eye exam and testing that determines whether surgery is necessary. The surgery itself — the removal of the cataract using traditional ultrasound phacoemulsification — is covered.
What Medicare does not cover is any technology beyond the standard approach. This includes femtosecond laser (which softens the cataract before removal), laser-assisted astigmatism correction, and premium lens options like multifocal or toric lenses designed to reduce your need for glasses afterward. If your surgeon recommends any of these add-ons, you pay for them separately.
How much you will owe out of pocket for traditional surgery
After you meet your Part B deductible (which is $240 in 2024, though this amount changes yearly), you pay 20 percent of what Medicare approves for the surgery. The exact amount depends on your surgeon and facility, but Medicare-approved amounts for cataract surgery typically range from $1,200 to $1,800 per eye. That means your 20 percent share is usually $240 to $360 per eye.
If you have a Medigap or Medicare Advantage plan, your out-of-pocket cost may be lower or zero, depending on your plan's coverage. Check your plan documents or call your plan's customer service line to find out what you owe before surgery.
Why laser surgery costs extra and what it does
Laser-assisted cataract surgery uses a femtosecond laser to create the incision, soften the cataract, and sometimes correct astigmatism (an irregular cornea shape that blurs vision). The laser allows more precision than a blade, and some surgeons say it reduces inflammation and healing time. However, Medicare does not consider these benefits significant enough to cover the technology — it views the outcome of laser and traditional surgery as equivalent for most patients.
The laser equipment itself is expensive, and surgeons pass that cost to patients who choose it. Facilities typically charge $1,500 to $3,000 per eye for the laser portion, though some charge more. Ask your surgeon whether they think laser surgery would benefit your specific situation, and get the exact additional cost in writing before you decide.
Premium lens options and what they cost
Medicare covers a standard monofocal intraocular lens — a single-vision lens that corrects distance vision. If you want a multifocal lens (which helps you see at multiple distances and may reduce your need for reading glasses) or a toric lens (which corrects astigmatism), you pay the difference between the standard lens and the premium one. This typically costs $500 to $1,500 per eye, depending on the lens type and facility.
Some surgeons bundle premium lens costs with laser surgery costs, and some charge them separately. Ask your surgeon to itemize what is covered by Medicare and what you are paying for out of pocket, so you understand each charge.
How to find out what your specific surgery will cost
Call your surgeon's office and ask for a cost estimate that breaks down what Medicare will cover and what you will owe. You need to know: the surgeon's fee, the facility fee, the cost of the standard lens, and the cost of any add-ons (laser, premium lens, or both). Ask whether your surgeon accepts Medicare assignment, which means they accept Medicare's approved amount as full payment for the parts Medicare covers.
If you have a Medicare Advantage plan instead of Original Medicare with Medigap, call your plan before surgery to confirm your out-of-pocket cost. Plans vary widely in what they cover beyond the standard procedure. If you do not have supplemental coverage, ask your surgeon's office whether they offer payment plans for the out-of-pocket portion.
What happens if you choose laser surgery but want Medicare to cover part of it
Medicare will still cover the traditional surgery portion — the surgeon's fee, facility, and standard lens. You pay 20 percent of that Medicare-approved amount (after your deductible), and you pay the full cost of the laser technology on top. Your surgeon's office should separate these costs on your bill so you can see what Medicare paid and what you paid.
Some patients choose laser surgery for one eye and traditional surgery for the other to compare results and manage cost. If you are considering this, discuss it with your surgeon first — they can tell you whether the comparison is likely to be meaningful given your specific vision needs.
Frequently Asked Questions
Does Medicare cover cataract surgery if I have not had symptoms yet?
No. Medicare only covers cataract surgery when the cataract is affecting your vision enough to interfere with your daily activities. Your eye doctor must document this in your medical record before Medicare will pay. If your cataract is present but not yet affecting your vision, surgery is not covered.
If I choose laser surgery, can I use my Medigap plan to cover the extra cost?
Medigap plans cover what Medicare does not cover for services Medicare deems medically necessary. Since Medicare considers laser surgery optional rather than necessary, most Medigap plans do not cover the laser portion. Check your specific plan documents or call your plan to be sure.
What if my surgeon says laser surgery is medically necessary for my eyes?
Even if your surgeon recommends laser surgery, Medicare will not cover it unless you have a specific condition (such as dense cataracts or certain corneal irregularities) that Medicare's guidelines recognize as requiring laser. Ask your surgeon to explain which Medicare guideline supports the recommendation, and request that they submit the documentation to Medicare before surgery if you want to challenge the denial.
Can I get a refund from Medicare if I pay for laser surgery and then regret it?
No. Once you choose and pay for laser surgery, that is your responsibility. Medicare does not refund out-of-pocket costs for elective add-ons. Make sure you understand the cost and benefit before you agree to the procedure.
Does Medicare cover both eyes in the same surgery visit?
Yes. Medicare covers cataract surgery on both eyes if both are medically necessary. You typically have the surgeries a week or two apart so your first eye heals before the second is operated on. Your out-of-pocket cost applies to each eye separately.
