Medicare's coverage of laser cataract surgery
Medicare Part B covers cataract surgery when your doctor determines it is medically necessary — meaning the cataract is affecting your vision enough to interfere with daily life. This includes both traditional blade surgery and laser-assisted cataract surgery. However, Medicare pays the same amount for both methods. If your surgeon uses a laser instead of a blade, Medicare does not pay extra, and you do not pay less.
The key point: Medicare covers the procedure itself, not the choice of surgical tool. You will pay the same out-of-pocket cost whether your surgeon uses a laser or performs the surgery by hand. If a surgeon tells you that laser surgery costs more because Medicare does not cover it, that is not accurate — the difference in your bill comes from the surgeon's fee for using the laser technology, which is separate from what Medicare pays.
Key Takeaways
- Medicare Part B covers cataract surgery (both laser and traditional) when medically necessary, but pays the same amount regardless of which method your surgeon uses.
- You pay 20 percent of the Medicare-approved amount after you meet your Part B deductible, which is the same whether the surgery is laser-assisted or traditional.
- If your surgeon charges extra for laser technology, that fee is separate from the Medicare-covered procedure and is your responsibility to pay in full.
- The total amount you owe depends on your specific plan, whether you have supplemental insurance, and your surgeon's agreement with Medicare.
How much you pay out of pocket
After you meet your Part B deductible (the amount varies yearly), Medicare pays 80 percent of the approved amount for cataract surgery. You pay the remaining 20 percent. For 2024, the Part B deductible is $240, but this changes annually. Once you have paid that deductible, you owe 20 percent of whatever Medicare approves for your surgery.
The actual dollar amount depends on where you live and which surgeon performs the procedure. Medicare sets different approved amounts in different regions. A surgeon who is a Medicare provider must accept the Medicare-approved amount as payment in full for the covered procedure. This means your 20 percent is calculated on that approved amount, not on whatever the surgeon might charge someone without insurance.
If you have a Medigap (supplemental insurance) plan, it may cover some or all of that 20 percent, depending on which plan you have. If you have a Medicare Advantage plan instead of Original Medicare, your out-of-pocket costs work differently — you pay whatever your plan specifies, which might be a copay, coinsurance, or a combination.
When your surgeon charges extra for laser technology
Some surgeons offer premium laser features — such as custom corneal mapping or femtosecond laser information — that go beyond what Medicare considers the standard cataract surgery procedure. When a surgeon uses these advanced features, they may charge you an additional fee on top of the Medicare-covered surgery cost. This extra charge is your responsibility to pay in full; Medicare will not reimburse any part of it.
Before surgery, your surgeon's office should give you a written estimate that separates the Medicare-covered portion from any additional charges for premium features. Ask specifically: "What is the cost of standard cataract surgery that Medicare covers, and what extra charges explore if I choose laser-assisted surgery?" Getting this in writing protects you from surprise bills later.
You are not required to pay for premium laser features. You can choose standard cataract surgery, which Medicare covers, and avoid the extra cost entirely. The choice is yours, and your surgeon should explain both options and their costs before the procedure.
Medicare Advantage plans and laser cataract surgery
If you have a Medicare Advantage plan (Part C), your coverage and costs for cataract surgery work differently than Original Medicare. Your plan sets its own rules about what it covers and what you pay. Some Medicare Advantage plans cover cataract surgery with little or no cost to you; others require a copay or coinsurance.
Call your Medicare Advantage plan before scheduling surgery and ask: "What is my cost for cataract surgery, and does it matter whether the surgeon uses laser or traditional methods?" Your plan's customer service line can tell you your exact responsibility. They can also tell you whether your preferred surgeon is in the plan's network, because using an out-of-network surgeon usually costs you more.
What to ask your surgeon before scheduling
Before you commit to cataract surgery, ask your surgeon's office these questions in writing so you have documentation:
- What is the total cost of standard cataract surgery that Medicare covers?
- Are there additional charges for laser-assisted surgery, and if so, how much?
- Do you accept Medicare assignment (meaning you accept the Medicare-approved amount as full payment for the covered procedure)?
- Will you provide a written estimate before surgery that breaks down the Medicare-covered cost and any additional charges?
- If I have a Medicare Advantage plan, do you participate in my plan's network?
A surgeon who participates with Medicare should be willing to answer these questions clearly. If the office is vague or refuses to provide a written estimate, that is a sign to ask for a second opinion elsewhere.
When to contact Medicare or your plan
Contact Medicare (1-800-MEDICARE) if you have questions about what the program covers for cataract surgery, or if you receive a bill that seems wrong. You can also visit Medicare.gov and search "cataract surgery" to read the official coverage rules.
If you have a Medicare Advantage plan, contact your plan directly — not Medicare — because your plan makes the coverage decisions. If you have Medigap, contact both your Medigap insurer and Medicare, because they coordinate coverage.
If you receive a bill from your surgeon that charges you for the Medicare-covered portion of the surgery (not just for premium add-ons), you may have received an improper bill. Report it to Medicare at 1-800-MEDICARE or file a complaint on Medicare.gov.
Frequently Asked Questions
Does Medicare cover both eyes in the same surgery visit?
Medicare covers cataract surgery on both eyes, but typically not on the same day. Most surgeons perform the surgery on one eye first, wait for it to heal, and then schedule the second eye. Medicare covers each surgery separately, and you pay your 20 percent coinsurance for each procedure.
What if my cataract is not affecting my vision much yet?
Medicare only covers cataract surgery when it is medically necessary — meaning your vision loss is significant enough to affect your daily activities. Your eye doctor determines this, not you or your surgeon. If your cataract is mild, Medicare will not cover surgery, and you would pay the full cost yourself if you choose to have it done.
Can I use a Health Savings Account to pay for cataract surgery?
If you have an HSA and are enrolled in a high-deductible health plan, you can use HSA funds to pay your out-of-pocket costs for cataract surgery. However, once you enroll in Medicare, you can no longer contribute to an HSA, though you can continue to withdraw funds for may have access to medical expenses.
Will I need a second surgery if the laser method does not work perfectly?
Cataract surgery — whether laser-assisted or traditional — has a high success rate. If your vision is not clear after surgery, your surgeon may need to perform a follow-up procedure, usually to correct astigmatism or to address a clouded lens capsule. Medicare covers medically necessary follow-up procedures the same way it covers the initial surgery.
What happens if I choose not to have cataract surgery?
Cataracts do not go away on their own and will gradually worsen over time. You do not have to have surgery, but your vision will continue to decline. Some people manage with stronger glasses or brighter lighting for a while. Your eye doctor can discuss with you when surgery becomes the best option for your situation.
