Medicare Part B covers cataract surgery, including the replacement lens implant, when the procedure is medically necessary. After you meet your annual Part B deductible, you pay 20% of the Medicare-approved amount for both the surgeon’s fee and the facility fee. Based on national averages for 2026 Medicare payments, that 20% works out to roughly $377 if your surgery is done in an ambulatory surgical center, or about $597 in a hospital outpatient department.
What Medicare Considers Medically Necessary
Medicare does not cover cataract surgery simply because a cataract exists. The cataract must be causing symptoms that impair your daily visual function in ways that can’t be fixed with new glasses, better lighting, or other non-surgical options. Specific activity limitations that qualify include difficulty reading, watching television, driving, or performing work or recreational tasks. If your cataract is mild and isn’t meaningfully affecting your life, Medicare will not approve the procedure.
There is no single eye-chart score that automatically qualifies you. Medicare’s policy explicitly states that visual acuity alone cannot rule surgery in or out. Your doctor will consider your overall visual impairment, how the cataract affects you in real-world conditions like glare, low contrast, and nighttime driving, and whether you have other eye conditions (such as diabetic retinopathy) that the cataract is preventing them from monitoring or treating.
Your Out-of-Pocket Costs With Original Medicare
With Original Medicare (Parts A and B), the math is straightforward. You first pay the annual Part B deductible ($257 in 2025), then you owe 20% of the Medicare-approved amount. That 20% applies to both the facility where the surgery takes place and the surgeon who performs it.
Where you have the surgery makes a real difference in cost. National average out-of-pocket figures from Medicare’s own price lookup tool show you’d pay about $377 at an ambulatory surgical center versus roughly $597 at a hospital outpatient department, per eye. If you have the option to choose between the two, an ambulatory surgical center typically saves you a couple hundred dollars. These are averages; your actual cost depends on your geographic area and what your surgeon charges.
If you have a Medigap (Medicare Supplement) plan, most plans cover that 20% coinsurance in part or in full, which can bring your out-of-pocket cost close to zero beyond your deductible. If you’re on a Medicare Advantage plan (Part C), your cost-sharing structure may differ. Medicare Advantage plans must cover everything Original Medicare covers, but they can use different copay amounts and may require prior authorization before approving surgery.
What’s Covered: Standard vs. Premium Lenses
Medicare pays for the removal of the cataract and the implantation of a conventional intraocular lens, which is a standard monofocal lens that corrects vision at one distance (usually far). This is fully covered under the normal Part B cost-sharing rules described above.
If you want a premium lens, such as a multifocal lens that corrects both near and far vision or a toric lens that corrects astigmatism, you will pay extra out of pocket. Medicare covers the portion of the procedure equivalent to what a standard lens implant would cost. The difference between that amount and the premium lens cost is yours to pay, and it can run anywhere from several hundred to a few thousand dollars per eye depending on the lens type.
Laser-Assisted Surgery
Some surgeons offer laser-assisted (femtosecond laser) cataract surgery instead of the traditional blade technique. Medicare’s position is clear: coverage and payment for cataract surgery is the same regardless of whether the surgeon uses a blade or a laser. Medicare will pay its standard amount for the cataract removal and conventional lens implant either way.
The catch comes if laser-assisted surgery is used alongside a premium lens. Services that are part of standard cataract surgery, including the incision, capsulotomy, and lens fragmentation, cannot be billed to you separately no matter what tool the surgeon uses. However, if a premium lens requires additional services like specialized imaging that wouldn’t be needed with a conventional lens, those extra charges can be passed on to you. Ask your surgeon’s office to break down what portion, if any, you’d owe beyond Medicare’s standard payment before scheduling.
Eyeglasses After Surgery
Medicare normally does not cover eyeglasses or contact lenses. Cataract surgery is the one exception. After each cataract surgery that includes a lens implant, Part B covers one pair of eyeglasses with standard frames or one set of contact lenses. You pay 20% of the Medicare-approved amount after your deductible. If you want upgraded frames, you pay the difference. The supplier must participate in Medicare for the benefit to apply.
This benefit resets with each cataract surgery, so if you have both eyes done at separate times, you’re entitled to a pair of corrective lenses after each procedure.
Surgery on the Second Eye
Medicare covers cataract surgery on each eye separately when each eye independently meets the medical necessity criteria. Most surgeons schedule the second eye a few weeks after the first to allow the operated eye to heal and stabilize. Each procedure is billed and covered individually, meaning you’ll pay the 20% coinsurance for each eye. If both surgeries fall in the same calendar year, you only need to meet the Part B deductible once.
