Medicare Covers Cataract Surgery, But You Pay Part of the Cost
Yes, Medicare Part B covers cataract surgery when your doctor says it is medically necessary. Medicare will pay for the surgeon's fee, the facility cost, and the basic intraocular lens (IOL) that replaces your clouded lens. You will pay 20% of the approved amount after you meet your Part B deductible for the year. If you have a Medigap or Medicare Advantage plan, your out-of-pocket cost may be lower.
The catch is that Medicare only covers a standard monofocal lens — the kind that corrects distance vision. If you want a lens that also corrects astigmatism or lets you see at multiple distances without glasses, you will pay the full difference out of pocket. That premium lens upgrade typically costs $500 to $2,500 per eye, depending on the type and your surgeon.
Key Takeaways
- Medicare Part B pays for cataract surgery and a basic intraocular lens when medically necessary, and you pay 20% of the approved amount after your deductible.
- Premium lens upgrades that reduce your need for glasses after surgery are not covered by Medicare and cost extra out of pocket.
- You will need pre-surgery testing and a doctor's note saying the cataract is affecting your vision enough to warrant surgery.
- Medicare Advantage plans may cover cataract surgery differently, so check your plan documents or call your plan before scheduling.
- Costs vary by surgeon, facility, and region, so getting a cost estimate from your provider before surgery helps you plan.
What Medicare Part B Actually Covers
Medicare Part B covers the surgical procedure itself, the facility fee (whether it is an outpatient surgery center or hospital), anesthesia, and post-operative care for the first few weeks. It also covers the standard monofocal intraocular lens that Medicare considers medically necessary to restore vision after the cataract is removed.
You do not pay anything upfront. Instead, you pay 20% of what Medicare approves after you have met your Part B deductible ($240 in 2024, though this amount changes yearly). If your surgeon's charge is higher than Medicare's approved amount, you are responsible only for the 20% of the approved amount — the surgeon cannot bill you for the difference if they accept Medicare.
Pre-surgery testing — the eye exam, measurements, and imaging that determine which lens power you need — is also covered by Part B. Your eye doctor will do this before you see the surgeon.
Premium Lens Options You Will Pay for Yourself
If you choose a lens that does more than basic distance correction, Medicare will not pay for the upgrade. The most common premium options are:
- Toric lenses correct astigmatism (blurred vision at all distances) in addition to distance vision. Cost: typically $500 to $1,500 per eye.
- Multifocal lenses let you see clearly at distance, intermediate, and near without bifocals or reading glasses. Cost: typically $1,500 to $2,500 per eye.
- Extended depth of focus (EDOF) lenses provide a wider range of clear vision than standard lenses but not quite as much as multifocals. Cost: typically $1,000 to $2,000 per eye.
If you choose a premium lens, Medicare still pays its share of the standard lens cost. You pay the difference between what the premium lens costs and what a standard lens would have cost, plus your usual 20% coinsurance on the standard lens portion.
How Much You Will Actually Pay Out of Pocket
Your total cost depends on three things: whether you have met your Part B deductible, which lens you choose, and your surgeon's approved charge.
If you have not met your $240 Part B deductible yet, you pay that first. Then you pay 20% of the approved surgical cost. For a straightforward cataract surgery with a standard lens at an outpatient center, the approved amount is usually $1,500 to $2,500, meaning your 20% share is roughly $300 to $500 per eye after the deductible.
If you add a premium lens, you pay the full upgrade cost on top of that. A toric lens upgrade might add $500 to $1,500 to your bill per eye. Ask your surgeon's office for a written cost estimate before you schedule surgery — they can tell you the exact approved amount and what your 20% will be.
Medicare Advantage Plans May Cover Cataract Surgery Differently
If you have a Medicare Advantage plan (Part C) instead of Original Medicare, your coverage for cataract surgery may be different. Some Advantage plans cover the standard lens with little or no copay. Others require a copay per visit or per procedure. A few plans cover certain premium lenses partially or fully, though this is uncommon.
You must use a surgeon and facility in your plan's network, or you may pay more or nothing may be covered. Before you schedule surgery, call your Advantage plan and ask: Does the plan cover cataract surgery? What is the copay or coinsurance? Which surgeons and facilities are in network? Does the plan cover any premium lens upgrades?
Your plan documents (the Summary of Benefits and Coverage) also list what is covered. You can find this on your plan's website or request it by phone.
What You Need Before Surgery Can Be Approved
Medicare requires that your eye doctor document that the cataract is affecting your daily vision and function enough to warrant surgery. This is not a formal process — it is part of the medical record your surgeon reviews. Your eye doctor will note things like your visual acuity (how clearly you see), glare symptoms, and how the cataract affects your ability to drive, read, or do other activities.
You will also have biometry testing, which measures your eye to determine the correct lens power. This is done before surgery and is covered by Medicare.
If your eye doctor or surgeon thinks surgery is not yet necessary, Medicare will not cover it. This sometimes happens when a cataract is mild and not yet affecting vision enough. In that case, you can have surgery anyway and pay the full cost yourself, or wait until the cataract progresses.
Medigap Plans and Cataract Surgery Costs
If you have a Medigap (supplemental insurance) plan, it may pay some or all of your 20% coinsurance on the surgery itself. Medigap plans vary widely — some cover 80% of your coinsurance, others cover 100%. Check your Medigap policy or call your plan to see what it covers for surgery.
Medigap does not cover premium lens upgrades, since Medicare does not cover them. You will still pay the full upgrade cost out of pocket.
If you do not have Medigap and cannot afford the 20% coinsurance, ask your surgeon's office about payment plans. Many facilities offer interest-free or low-interest financing for out-of-pocket costs.
Frequently Asked Questions
Can I have cataract surgery on both eyes at once?
No. Medicare and most surgeons require surgery on each eye at separate visits, usually one to three weeks apart. This allows your first eye to heal and your vision to stabilize before the second surgery. You will pay the 20% coinsurance for each eye separately, though your deductible applies only once per year.
What if my cataract surgery goes wrong and I need a second procedure?
Complications are rare, but if they happen, Medicare covers the treatment as part of your post-operative care. You would pay your usual 20% coinsurance. Ask your surgeon what their complication rate is and what their policy is on revision surgery if needed.
Does Medicare cover glasses or contacts after cataract surgery?
Medicare does not cover eyeglasses or contact lenses after cataract surgery, even if you still need them for reading or distance vision. If you choose a standard monofocal lens, you will likely need reading glasses or bifocals. Some vision insurance plans or discount programs cover post-surgery glasses — ask your eye doctor about options.
What if I want laser-assisted cataract surgery instead of standard surgery?
Laser-assisted surgery (femtosecond laser) is not covered by Medicare as a separate procedure. Medicare covers the standard surgical technique. If your surgeon recommends laser-assisted surgery and you choose it, you pay the full extra cost out of pocket, which is typically $500 to $1,500 per eye.
How do I know if my surgeon accepts Medicare?
Ask your eye doctor or surgeon's office directly. You can also search the Medicare Physician Compare tool on Medicare.gov by entering the surgeon's name and location. If your surgeon accepts Medicare, they accept the approved amount as payment in full for the standard procedure.
