Medicare Coverage for Cataract Surgery: Comparing Humana, UnitedHealthcare, and Aetna Plans and Finding Surgeons Near You

If you're on Medicare and dealing with cataracts, the most important thing to know is that Humana, UnitedHealthcare, Aetna, and most other Medicare Advantage plans are required to cover medically necessary cataract surgery — often at significantly lower out-of-pocket cost than Original Medicare alone.

  And if you're weighing cataract surgery against LASIK, your coverage options are very different depending on which procedure you need.

This guide covers what Original Medicare pays, how Medicare Advantage plans from Humana, UnitedHealthcare, and Aetna handle cataract surgery costs, how to find a participating ophthalmologist or cataract surgery clinic near you, and how cataract surgery compares to LASIK for Medicare-age patients.

Does Medicare cover cataract surgery?

Yes — cataract surgery is one of the clearest examples of a procedure explicitly covered by Medicare when it is medically necessary. Under Medicare Part B, coverage includes the surgeon and anesthesia fees, the outpatient facility (ambulatory surgical center or hospital outpatient department), removal of the cloudy lens, and implantation of a standard monofocal intraocular lens (IOL).

After you meet your annual Part B deductible, Medicare pays 80% of the Medicare-approved amount. You're responsible for the remaining 20% coinsurance plus any applicable facility copay. For most patients, the total out-of-pocket cost for standard cataract surgery under Original Medicare is a few hundred dollars per eye — especially if your deductible is already met for the year.

Medicare Part B also covers one pair of eyeglasses or contact lenses after cataract surgery — a benefit many beneficiaries don't know about. Standard Part B cost-sharing applies (typically 20% of the approved amount).

How Humana Medicare Advantage covers cataract surgery

Humana Medicare Advantage plans — including Humana Gold Plus HMO, Humana Choice PPO, and Humana's Special Needs Plans — are required to cover cataract surgery at least as well as Original Medicare. In most cases, Humana Advantage plans reduce what you pay beyond the standard 80/20 split.

Specific Humana plan benefits for cataract surgery vary by plan and location. Key questions to ask when verifying your Humana coverage:

  • What is my copay or coinsurance for outpatient surgery at an in-network ambulatory surgical center?
  • Is prior authorization required before scheduling?
  • Which ophthalmologists and surgical centers are in my Humana network?
  • Does my plan's OTC or supplemental benefit apply to post-surgical eyewear?

If you have a Humana Dual Eligible Special Needs Plan (D-SNP), Medicaid may also cover your Medicare cost-sharing — potentially bringing your out-of-pocket cost to $0. Call Humana member services at 1-800-4HUMANA or log into MyHumana to confirm your plan's surgical benefits before scheduling.

How UnitedHealthcare Medicare Advantage covers cataract surgery

UnitedHealthcare, including AARP-branded Medicare Advantage plans underwritten by UnitedHealthcare, covers medically necessary cataract surgery under the same framework as Original Medicare, with plan-specific cost-sharing that often reduces what you owe.

UnitedHealthcare Medicare Advantage plans commonly include:

  • Set copays for outpatient surgical procedures at in-network facilities (often $0–$300 per eye depending on plan tier)
  • Coverage for the surgeon's fee, anesthesia, and facility at in-network rates
  • In some plans, additional vision benefits that cover your post-surgical eyeglasses

Use UnitedHealthcare's online provider directory or call the number on your insurance card to confirm your surgeon and the surgical center are in-network before booking. Out-of-network procedures will cost significantly more, and some plans require prior authorization.

How Aetna Medicare Advantage covers cataract surgery

Aetna Medicare Advantage plans also cover medically necessary cataract surgery. Aetna's plan structures vary — some use copay-based surgical benefits, others apply coinsurance — so the specific amount you pay depends on your plan, the facility type, and whether you use an in-network provider.

Before scheduling with any surgeon, call Aetna member services (the number is on your insurance card) and ask: Does this plan require prior authorization for cataract surgery? What is my cost-share at an in-network ambulatory surgical center? Is the facility and surgeon I've chosen in-network?

If you have Medicare A and B — do you need additional coverage for cataract surgery?

Original Medicare (Parts A and B) does cover cataract surgery, but you'll still owe 20% coinsurance after the deductible. For a surgery that costs $3,000–$5,000 in total allowed charges per eye, that's $600–$1,000 out of pocket per eye under Original Medicare alone. Three options can reduce this:

  1. Medicare Advantage (Part C): A Humana, UnitedHealthcare, Aetna, or other Advantage plan may offer lower set copays for outpatient surgery, potentially $0–$300 per eye. You can switch plans during the Annual Enrollment Period (October 15 – December 7) or the Medicare Advantage Open Enrollment Period (January 1 – March 31) at Medicare.gov Plan Compare.
  2. Medigap (Medicare Supplement): A Medigap plan can cover your Part B coinsurance, potentially reducing your cost to $0 for the standard surgery portion. Medigap plans F and G are the most comprehensive, though availability and pricing vary by state.
  3. Dual eligibility (Medicare + Medicaid): If you qualify for both Medicare and Medicaid, Medicaid may cover your Medicare cost-sharing. Medicaid for Medicare beneficiaries can bring costs to near $0.

What Medicare doesn't cover — premium upgrade costs

Medicare covers the standard monofocal IOL. If you choose a premium lens — such as a toric lens (corrects astigmatism) or a multifocal/extended depth-of-focus (EDOF) lens (reduces dependence on reading glasses) — Medicare pays what it would have paid for a monofocal lens, and you pay the upgrade difference. Per CMS Ruling 05-01, beneficiaries may pay for non-covered premium features. Typical premium lens upgrades run $500–$3,000 per eye depending on technology and market.

Laser-assisted cataract surgery (using a femtosecond laser) is similarly an elective upgrade. Medicare covers the standard phacoemulsification procedure; any additional laser fee — typically $500–$1,000 per eye — is your responsibility. Ask your surgeon for a written estimate separating covered costs from optional upgrade fees before you commit.

How to find cataract surgery clinics near you that accept Medicare

Finding a Medicare-participating ophthalmologist and surgical facility is the most important step in managing your costs. If your surgeon accepts Medicare assignment, they agree to the Medicare-approved amount as full payment — you pay only the coinsurance and any applicable deductible, with no surprise billing above the approved amount.

Three tools to find participating providers near you:

  • Medicare Care Compare — search for ophthalmologists by location, see quality indicators, and verify Medicare participation status.
  • AAO's Find an Ophthalmologist — directory of board-certified eye surgeons from the American Academy of Ophthalmology.
  • Your Medicare Advantage plan's provider directory — if you have a Humana, UnitedHealthcare, or Aetna Advantage plan, use their directory to find in-network ophthalmologists specifically, since out-of-network procedures can cost significantly more.

When you call a surgeon's office to schedule, confirm two things: "Do you accept Medicare assignment?" and "Is the ambulatory surgical center where you operate also Medicare-participating?" Both the surgeon and the facility need to accept assignment for your costs to be predictable.

Cataract surgery vs. LASIK — how Medicare coverage differs

Medicare patients frequently ask whether LASIK is covered as an alternative to cataract surgery. The short answer is no — but the distinction matters.

Cataract surgery removes a cloudy lens that is impairing vision due to a medical condition (cataracts). Medicare Part B covers it when medically necessary because it treats a diagnosed disease. The procedure is typically performed by an ophthalmologist in an ambulatory surgical center under light sedation.

LASIK (Laser-Assisted In Situ Keratomileusis) reshapes the cornea to correct refractive errors — nearsightedness, farsightedness, and astigmatism — in eyes with otherwise healthy lenses. It is considered an elective cosmetic procedure, not a treatment for a medical condition. Medicare does not cover LASIK regardless of your plan.

For Medicare-age patients, cataracts and refractive errors often coexist. In those cases, your cataract surgery can be combined with a premium toric IOL to address astigmatism at the same time — giving you some of the benefit LASIK would provide for astigmatism correction, with Medicare covering the base surgery and you paying the premium lens upgrade fee. This is worth discussing with your ophthalmologist if you have both cataracts and significant astigmatism.

If you are evaluating LASIK independently (for a family member, for example, or if you are pre-Medicare age), LASIK costs typically range from $2,000–$4,000 per eye and are not covered by insurance. Discount LASIK pricing (advertised around $299–$499 per eye) typically reflects basic blade-LASIK on low prescriptions; custom LASIK and premium centers charge more. LASIK can be paid with HSA or FSA funds.

What the cataract surgery procedure involves

Cataract surgery (phacoemulsification) is an outpatient procedure typically taking 10–20 minutes per eye. Under light sedation and numbing eye drops, the surgeon makes a tiny incision, uses ultrasound to break up the cloudy lens, removes it by suction, and inserts a clear IOL. Most patients notice improved vision within 24–48 hours. Full healing takes about 4–6 weeks, during which you'll use antibiotic and anti-inflammatory eye drops and attend follow-up visits.

If you need surgery on both eyes, procedures are typically scheduled one to three weeks apart. If you've already met your Part B deductible in the year of the first surgery, the deductible won't apply again for the second eye in the same calendar year.

The American Academy of Ophthalmology reports that cataract surgery is one of the most commonly performed and most successful surgeries in the world, with the vast majority of patients experiencing significantly improved vision.

Step-by-step: how to get cataract surgery covered under Medicare

  1. Get a diagnosis from your ophthalmologist. Your doctor will document that cataracts are affecting your functional vision — this establishes medical necessity for Medicare purposes.
  2. Verify your coverage. If you have a Medicare Advantage plan (Humana, UnitedHealthcare, Aetna, or other), call member services to confirm your surgical copay, prior authorization requirements, and which facilities are in-network.
  3. Choose a Medicare-participating surgeon and facility. Use Medicare Care Compare or your plan's directory to find in-network ophthalmologists and ambulatory surgical centers near you.
  4. Get a written cost estimate. Ask the surgeon's office for an Advance Beneficiary Notice (ABN) if any services may not be covered, and a written estimate separating Medicare-covered costs from optional upgrade fees.
  5. Complete prior authorization if required. Your surgeon's office typically handles this, but confirm it's submitted and approved before your surgery date.
  6. Schedule surgery and post-op follow-ups. Your plan will cover required follow-up visits to monitor healing as part of the global surgical period.
  7. Use your post-surgical eyewear benefit. After surgery, ask your ophthalmologist for a prescription and use your Medicare Part B benefit for one pair of glasses or contact lenses through a Medicare-enrolled optical provider.

Common questions about Medicare and cataract surgery

How much does cataract surgery cost with Medicare?

With Original Medicare, your out-of-pocket for standard cataract surgery is typically 20% of the Medicare-approved amount for the surgeon's fee, plus a facility copay at an ambulatory surgical center (around $50–$150 per procedure on average). Medigap plans can reduce or eliminate your coinsurance. Medicare Advantage plans often replace coinsurance with a set copay — anywhere from $0 to $300 per eye depending on the plan.

Does Medicare cover both eyes?

Yes. Medicare covers cataract surgery on both eyes when each is medically necessary — typically one surgery at a time, scheduled weeks apart. Your annual deductible only applies once per year, so if your first surgery occurs after you've met the deductible, the second surgery in the same year has no deductible.

Can I switch to a Medicare Advantage plan to reduce my costs?

Yes. If your current coverage leaves you with high out-of-pocket costs, you can compare Humana, UnitedHealthcare, Aetna, and other Advantage plans during open enrollment using Medicare.gov Plan Compare. Look for plans with low or $0 surgical copays and verify your preferred ophthalmologist is in-network before switching.

What if I can't afford the 20% coinsurance?

If you have limited income, you may qualify for a Medicare Savings Program, which can help pay your Part B premiums and cost-sharing. Medicare Savings Programs are administered by state Medicaid programs. You can also ask the surgical center's billing department about payment plans or financial assistance programs.
