Cataract surgery is among the most frequently performed procedures for people on Medicare. If your eye doctor has told you that a cataract is clouding your vision, you probably have two immediate questions: does Medicare pay for the surgery, and how much will you owe out of pocket? The answers are generally reassuring, but the details — especially lens choices and where the surgery is performed — can make a meaningful difference in your final bill. Here is what Medicare generally covers, what you may pay in 2026, and the questions worth asking before you schedule the procedure.
The Short Answer
Medicare Part B generally covers cataract surgery when it is medically necessary — that is, when the cataract is significantly impairing your vision and your doctor determines that surgery is the appropriate treatment. Coverage decisions are made on an individual basis, so your doctor's documentation of medical necessity matters.
Under Original Medicare, cost-sharing typically works like this in 2026:
- You first meet the Part B annual deductible of $283 (2026), if you have not already met it earlier in the year
- After that, you pay 20% coinsurance of the Medicare-approved amount for the surgery and related services
- Medicare pays the remaining 80% of the approved amount
Note that the standard Part B monthly premium is $202.90 in 2026 — that is what you pay to have Part B coverage in the first place, separate from any cost-sharing for the surgery. If you are unclear on how coinsurance differs from flat copayments, see our guide to copays vs. coinsurance.
What's Included in Medicare's Coverage
When cataract surgery is medically necessary, Part B coverage generally extends across the full episode of care, not just the operation itself:
- Pre-surgery exams related to diagnosing and evaluating the cataract, including the measurements needed to select your lens implant
- The surgical procedure, whether traditional or laser-assisted when medically necessary
- Implantation of a standard monofocal intraocular lens (IOL) — the artificial lens that replaces your eye's clouded natural lens
- Post-operative care, including follow-up visits
If you have cataracts in both eyes, surgery on both eyes is covered. Surgeons typically operate on one eye at a time, on separate days — often a few weeks apart — so the first eye can heal before the second surgery. Your cost-sharing applies to each procedure.
Cataract surgery is almost always an outpatient procedure, which is why Part B covers it rather than Part A. For more on how Medicare handles procedures without an inpatient admission, see our guide to outpatient surgery and observation stays.
What Costs Extra
This is where many people are surprised. Medicare covers cataract surgery with a standard monofocal IOL — a lens set to a single focal distance, usually for distance vision. Most people who choose a monofocal lens still need glasses for reading afterward.
Premium lenses are an out-of-pocket upgrade. If you and your surgeon choose one of the following, Medicare pays only what it would have paid for the standard lens and procedure, and you pay the difference:
- Multifocal lenses, which provide both near and distance vision
- Extended-depth-of-focus (EDOF) lenses, which offer a continuous range of vision
- Toric lenses, which correct astigmatism
The upgrade cost for premium lenses typically runs $1,500 to $4,000 per eye in 2026, depending on the lens type and the additional testing and services that come with it. This amount is billed outside Medicare, so it does not count toward your deductible or coinsurance.
Where you have the surgery also affects your bill. The national Medicare payment rate for routine cataract surgery at an ambulatory surgical center (ASC) is roughly $1,255 in 2026 — that is the facility fee, with the surgeon's professional fee billed separately (roughly $600 to $900). Hospital outpatient departments generally have higher Medicare-approved amounts for the same procedure. Your 20% coinsurance applies to these Medicare-approved amounts, so the same surgery can cost you noticeably more at a hospital outpatient department than at an ASC. Approved amounts vary by geographic area, so ask for the figures that apply to your facility.
The One-Time Glasses Benefit
Original Medicare does not cover routine eyeglasses — with one exception: cataract surgery.
After cataract surgery that implants an intraocular lens, Part B covers one pair of standard eyeglasses or one set of contact lenses. This is the only situation in which Original Medicare pays for glasses. A few details to keep in mind:
- You pay 20% coinsurance of the Medicare-approved amount, and the Part B deductible applies
- Coverage is for standard frames and lenses — if you choose upgraded frames or lens add-ons, you pay those extra costs yourself
- You must purchase the glasses or contacts from a supplier enrolled in Medicare

How Medicare Advantage Handles Cataract Surgery
Medicare Advantage plans must cover at least what Original Medicare covers, including medically necessary cataract surgery and the standard monofocal lens. The differences are in how you pay and the rules you follow:
- Cost-sharing is usually structured as copays — a set dollar amount for outpatient surgery — rather than the 20% coinsurance under Original Medicare. Depending on the plan, this could work out to more or less than Original Medicare's coinsurance.
- Network rules may apply. Your plan may require you to use an in-network surgeon and facility, or charge higher cost-sharing for out-of-network care.
- Prior authorization may be required before the plan approves the surgery.
- Medicare Advantage plans include an annual maximum out-of-pocket limit on covered Part A and Part B services, which Original Medicare alone does not have. Our guide to Medicare out-of-pocket limits explains how these caps work.
Check your plan documents or call your plan to confirm what you would pay for cataract surgery at the facility your surgeon uses.
How Medigap May Help
If you have Original Medicare plus a Medicare Supplement (Medigap) policy, your out-of-pocket costs may be substantially lower. Medigap plans may cover the 20% Part B coinsurance, depending on which plan you have. That means a medically necessary cataract surgery with a standard lens could result in little or no cost-sharing for you — though a Medigap policy does not pay for premium lens upgrades, since those charges fall outside Medicare entirely. If you are weighing supplemental coverage, our guide to whether Medigap is worth the cost can help you think it through.
Questions to Ask Your Surgeon
Before you schedule surgery, a short conversation about billing can prevent surprises. Consider asking:
- Which facility will you use — an ASC or a hospital outpatient department — and how does that affect my share of the cost?
- Which lens are you planning to implant? Is it the standard monofocal lens Medicare covers, or a premium lens with extra charges?
- Will any portion of the procedure or testing be billed outside Medicare? Ask specifically about astigmatism correction and advanced lens measurements.
- Can I get a total out-of-pocket estimate in writing before the surgery date?

Summary and Next Steps
Medicare coverage for cataract surgery is generally straightforward, but lens choices and facility setting can change your bill considerably. Key points to remember:
- Part B generally covers medically necessary cataract surgery, including pre-surgery exams, the procedure, a standard monofocal IOL, and post-operative care
- You typically pay 20% coinsurance after the $283 Part B deductible (2026)
- Premium lenses (multifocal, EDOF, toric) are an out-of-pocket upgrade of roughly $1,500–$4,000 per eye
- Surgery at an ASC generally costs less than the same procedure at a hospital outpatient department
- Part B covers one pair of standard glasses or contacts after surgery — the only time Original Medicare pays for eyeglasses
- Medicare Advantage plans cover the surgery too, but usually with copays, network rules, and possible prior authorization
- Medigap may cover the 20% coinsurance, depending on the plan
If cataract surgery is on your horizon, start by asking your surgeon's office for a written cost estimate that spells out the facility, the lens, and any charges billed outside Medicare. Then compare that against your coverage — and if anything is unclear, your local SHIP counselor can walk through the numbers with you for free.
