Medicare Coverage for Cataract Surgery: What’s Covered, What You Pay

Cataracts are the leading cause of vision loss in older Americans — and cataract surgery is the single most common procedure performed on Medicare beneficiaries each year. More than 3 million cataract operations are done annually in the United States, with the majority of patients covered by Medicare. Understanding exactly what Medicare pays for, and where your out-of-pocket costs come in, can help you plan ahead and avoid surprises.

Does Medicare Cover Cataract Surgery?

Yes. Medicare Part B covers medically necessary cataract surgery, including the implantation of a basic intraocular lens (IOL). This coverage applies when the surgery is performed by a Medicare-enrolled surgeon at a Medicare-approved facility — either an ambulatory surgical center (ASC) or a hospital outpatient department.

The key word is medically necessary. Cataracts are covered when they impair your vision enough to interfere with your daily activities. Your ophthalmologist documents this medical necessity, and Medicare does not typically second-guess it for genuine cataracts. Cosmetic eye procedures — such as LASIK, PRK, or other refractive surgery to eliminate glasses or contacts — are not covered.

What Part B Pays For

When your cataract surgery meets Medicare’s criteria, Part B covers the following:

Pre-operative examination: The visit where your ophthalmologist evaluates your eye, measures it for the IOL, and determines you are a surgical candidate. This is billed as an office visit under Part B.

The surgical procedure itself: Medicare pays 80% of the Medicare-approved amount for the surgery after you meet your annual Part B deductible ($257 in 2025). You pay the remaining 20% coinsurance.

Standard IOL implantation: During cataract surgery, the surgeon removes the cloudy natural lens and replaces it with a clear artificial lens — the intraocular lens. Medicare covers the cost of a standard monofocal IOL, which corrects vision at one focal distance (usually distance). After the IOL is implanted, most people still need reading glasses for close work.

One pair of glasses or contact lenses after surgery: This is a unique exception to Medicare’s usual exclusion of eyewear. Following cataract surgery with IOL implantation, Medicare Part B covers one pair of conventional frames and lenses (or one set of contacts) per eye operated on. This applies to standard frames and lenses; premium frames cost more out of pocket.

Anesthesia services: Provided by an anesthesiologist or CRNA, billed separately and also covered under Part B at the 80% rate.

Facility fees: Whether you have surgery in an ASC or a hospital outpatient department, the facility bills Medicare separately from the surgeon. Part B covers 80% of the approved facility fee; you pay 20%.

Post-operative care: Follow-up visits in the weeks after surgery are covered under the global surgery fee that Medicare pays the surgeon — typically no additional charge to you for routine post-op visits included in the global period (90 days for cataract surgery).

What You Pay for Standard Cataract Surgery

Under Original Medicare only (no supplement):

• Part B deductible: $257 for 2025 (applies once per year to all Part B services; if you’ve already met it, you owe $0 on deductible)
• Surgeon fee: 20% of Medicare-approved amount (typically $300–$500 per eye)
• Facility fee: 20% of the facility’s approved amount (ASC: lower; hospital outpatient: higher)
• Anesthesia: 20% coinsurance

A typical total out-of-pocket for a single eye under Original Medicare without a supplement runs $400–$800, though amounts vary by location and provider.

If you have a Medigap (Medicare Supplement) plan, the plan pays most or all of your 20% coinsurance. Plan G, the most popular comprehensive plan, covers the 20% coinsurance entirely — meaning your only cost may be the Part B deductible if not yet met. See Medigap plans compared for a full breakdown of what each plan covers.

If you have Medicare Advantage, your cost depends on your specific plan’s copay and coinsurance schedule, your surgeon’s network status, and whether surgery is at an in-network facility. Compare Medicare Advantage vs. Original Medicare to understand how cost-sharing works differently under each approach.

Premium IOLs: The Upgrade That Medicare Doesn’t Cover

This is where many patients are surprised. While Medicare covers a standard monofocal IOL, several premium lens types exist that offer added benefits — but Medicare does not pay the extra cost for the upgrade.

Multifocal IOLs correct vision at multiple distances (near, intermediate, far), potentially reducing or eliminating the need for glasses after surgery. They cost roughly $1,500–$3,000 extra per eye beyond what Medicare pays.

Toric IOLs correct astigmatism in addition to cataracts. Medicare covers the basic cataract procedure but not the additional cost of the toric lens, which runs approximately $1,000–$1,500 extra per eye.

Extended-depth-of-focus (EDOF) IOLs provide a range of vision with fewer halos than multifocal lenses. Similar extra cost to multifocal lenses.

Medicare’s position: the cataract itself (lens opacity) is the medical problem; correcting refractive error or astigmatism beyond that is elective. Therefore, Medicare covers the monofocal lens that treats the cataract and you pay any additional cost for premium features.

Your surgeon will present these options, and there is nothing wrong with choosing a premium lens if you want it. Just understand that the premium lens cost is your responsibility — typically paid directly to the surgical facility in advance.

Ambulatory Surgical Centers vs. Hospital Outpatient Departments

Cataract surgery can be performed in either an ambulatory surgical center or a hospital outpatient department. The cost difference matters:

ASC: Usually lower facility fees. Medicare has a set ASC payment rate for cataract surgery, and your 20% is based on that lower amount. Many surgeons prefer ASCs for cataract surgery because they are efficient and specialized.

Hospital outpatient department: Higher facility fees because hospitals have more overhead. The same surgery often costs you more in 20% coinsurance at a hospital outpatient department than at an ASC.

Ask your surgeon which setting they use and, if you have a choice, an ASC is typically the better deal under Original Medicare. If you have Medigap, the difference matters less since the plan pays the 20% either way.

Both Eyes: Timing and Coverage

Cataract surgery is almost never done on both eyes the same day. Your surgeon will typically operate on one eye, let it heal for a few weeks, and then schedule the second eye. Each eye is billed as a separate procedure.

This means you face cost-sharing for each eye separately. If both surgeries fall in the same calendar year and you’ve already met your Part B deductible, you pay only the 20% coinsurance for both procedures. If the second eye surgery falls in the following calendar year, you face the Part B deductible again before the 20% applies.

Strategic planning: if possible, schedule both surgeries in the same calendar year to apply the deductible only once. Talk to your ophthalmologist about timing.

Medicare Advantage Coverage for Cataract Surgery

Medicare Advantage plans must cover everything Original Medicare covers, including cataract surgery. However, the cost-sharing structure differs:

• HMO plans require you to use in-network surgeons and facilities. Out-of-network surgery is not covered except in emergencies. Confirm your surgeon participates in your plan’s network before scheduling.
• PPO plans cover both in-network and out-of-network surgeons, but out-of-network costs more.
• Copays vs. coinsurance: Many MA plans charge a flat copay for outpatient surgery rather than 20% coinsurance. Depending on the copay amount and the surgery cost, this can be higher or lower than what you’d pay under Original Medicare plus Medigap.

Some Medicare Advantage plans offer extra vision benefits — routine eye exams, glasses allowances — that Original Medicare doesn’t cover. See Medicare dental, vision, and hearing coverage for details on these extras.

LASIK and Refractive Surgery: Not Covered

To be clear: Medicare does not cover LASIK, PRK, or any other refractive surgery to correct nearsightedness, farsightedness, or astigmatism in otherwise healthy eyes. These are cosmetic/elective procedures from Medicare’s standpoint.

If you have cataracts and want refractive correction, Medicare covers the cataract procedure itself but not the refractive component. This is precisely why the premium IOL cost-sharing structure exists — the premium lens’s refractive benefit is the patient’s elective choice.

Low-Income Help with Cataract Surgery Costs

If you have limited income and resources, Medicare Savings Programs — Qualified Medicare Beneficiary (QMB), Specified Low-Income Medicare Beneficiary (SLMB), or Qualifying Individual (QI) — can eliminate or reduce your Part B deductible and coinsurance. QMB, the most comprehensive program, pays your Medicare cost-sharing including the 20% for cataract surgery.

Contact your State Health Insurance Assistance Program (SHIP) for free help determining eligibility. Income and asset limits vary by state.

What to Ask Before Scheduling Surgery

Before your cataract surgery date, get clear answers to these questions:

1. What type of IOL does the surgeon recommend? If premium, what is the extra cost and why is it appropriate for your eyes?
2. Is this surgeon a Medicare-enrolled provider? (Almost all ophthalmologists are, but confirm.)
3. Is the surgical facility Medicare-approved? ASC or hospital outpatient?
4. What will my estimated out-of-pocket cost be? Ask the billing department, not just the surgeon.
5. If I have Medicare Advantage, is this surgeon in-network? Call your plan’s member services line.
6. Has my Part B deductible been met for the year? Check your Medicare Summary Notice or Medicare.gov account.

Planning Your Costs

Cataract surgery is one of the most cost-effective Medicare procedures in terms of outcome per dollar — it restores independence and reduces fall risk. Standard surgery with a basic IOL under Original Medicare plus a Medigap plan is essentially cost-free beyond the deductible. Without a Medigap plan, you’re looking at a few hundred dollars per eye in cost-sharing.

For the broader context of Medicare out-of-pocket costs in retirement, cataract surgery is a manageable, predictable expense — unlike some other procedures. The premium lens upgrade is the main wildcard, and it’s entirely optional.

If you’re approaching 65 and weighing Original Medicare plus Medigap versus a Medicare Advantage plan, compare the costs of each approach before enrolling — the choice affects every procedure, not just cataract surgery.
