Medicare Part B covers cataract removal when your doctor says it is medically necessary

Yes. Medicare Part B pays for cataract removal surgery when a cataract is affecting your vision enough that your eye doctor recommends surgery. Medicare does not cover the surgery if the cataract is present but not yet affecting how you see. You pay 20 percent of the cost after you meet your Part B deductible for the year; Medicare pays the other 80 percent.

The surgery itself is covered at an outpatient facility or hospital. This includes the surgeon's fee, the facility cost, and the basic intraocular lens (IOL) — the artificial lens placed in your eye during surgery. You will also need an eye exam before surgery to measure your eye and plan the procedure; Medicare covers this exam as well.

Key Takeaways

  • Medicare Part B covers cataract removal surgery when your eye doctor determines it is medically necessary to restore or improve your vision.
  • You pay 20 percent of the approved cost after meeting your annual Part B deductible; Medicare pays 80 percent.
  • The basic intraocular lens is included in Medicare coverage, but premium lens options cost extra and are your responsibility.
  • You will need a referral or recommendation from your eye doctor, and the surgery must take place at a Medicare-approved facility.
  • If you have a Medigap or Medicare Advantage plan, your out-of-pocket costs may be lower than the standard 20 percent.

What the 20 percent cost means in real dollars

The amount you pay depends on what Medicare approves for cataract surgery in your area. Medicare sets approved amounts by region, and they vary. In most parts of the country, the approved amount for cataract surgery ranges from roughly $3,000 to $4,500, though this can be higher or lower depending on your location and whether complications arise during surgery.

If the approved amount is $3,500, you would pay $700 (20 percent) after you have met your Part B deductible. If you have not yet met your deductible that year, you pay the full deductible first, then 20 percent of the remaining cost. Your surgeon's office can tell you the approved amount for your area and help you estimate your share before surgery.

Premium lens upgrades and what they cost

Medicare covers only the standard monofocal intraocular lens — a single-focus lens that usually corrects distance vision. If you want a premium lens that corrects both distance and near vision (multifocal), or one that corrects astigmatism (toric), you pay the difference in cost out of your own pocket. This upgrade typically costs between $500 and $2,500 per eye, depending on the lens type and your surgeon.

Ask your eye surgeon which lens options are available and what each one costs before surgery. Some surgeons bundle the upgrade cost into their total fee; others bill it separately. Understanding the cost upfront helps you decide whether the upgrade is worth it for your situation.

How to prepare for surgery and what to bring

Your eye doctor will refer you to a surgeon or cataract surgery center. Before the surgery date, you will have a pre-operative eye exam where the surgeon measures your eye and discusses which lens power will work best for you. Bring your Medicare card and any other insurance cards you have (Medigap or Medicare Advantage) to all appointments.

On surgery day, arrange for someone to drive you home — you cannot drive yourself after cataract surgery. Bring your insurance cards again, and ask the facility which paperwork they need from you. Most facilities will verify your Medicare coverage before surgery so there are no surprises about your cost.

Medigap and Medicare Advantage coverage for cataract surgery

If you have a Medigap plan, it may cover some or all of your 20 percent cost-sharing, depending on which plan you have. Plans C, D, F, and G typically cover the Part B coinsurance, meaning you would owe little or nothing after Medicare pays. Check your Medigap plan documents or call your plan to confirm what cataract surgery coverage includes.

If you have a Medicare Advantage plan, your coverage and out-of-pocket costs work differently. Most Medicare Advantage plans cover cataract surgery, but you may have a copay or coinsurance amount set by your plan. Some plans require you to use an in-network surgeon. Call your Medicare Advantage plan before scheduling surgery to learn your exact cost and whether your surgeon is in-network.

What happens if you delay surgery

A cataract that is not yet affecting your vision is not covered by Medicare. If your eye doctor says your vision is still good enough that surgery is not medically necessary, Medicare will not pay for it. You can choose to pay out of pocket for early surgery, but most people wait until the cataract makes everyday tasks like reading or driving harder.

Once your vision declines enough that your doctor recommends surgery, Medicare coverage becomes available. There is no waiting period or prior approval process — your doctor's recommendation that surgery is medically necessary is what triggers coverage. However, some Medicare Advantage plans may require prior authorization, so check with your plan before scheduling.

After surgery: follow-up care and eye drops

Medicare Part B covers the follow-up eye exams after cataract surgery. These visits are important to make sure your eye is healing well and your vision is improving as expected. You pay 20 percent of the approved amount for each follow-up visit after you meet your deductible.

Prescription eye drops you use after surgery are covered by Medicare Part D (prescription drug coverage) if you have it. Over-the-counter eye drops are not covered. If you do not have Part D, you pay the full cost of prescription drops out of pocket. Ask your surgeon which drops you will need and for how long.

Frequently Asked Questions

Do I need my doctor's permission before I can have cataract surgery?

Your eye doctor must determine that the cataract is affecting your vision enough to recommend surgery. Medicare does not require a formal approval process, but your surgeon will document that surgery is medically necessary. If you want surgery before your doctor thinks it is needed, you can pay out of pocket, but Medicare will not cover it.

What if I have both Medicare and Medicaid?

Medicaid rules vary by state. In most states, Medicaid will cover costs that Medicare does not, including your 20 percent coinsurance. Contact your state Medicaid office or your Medicaid plan to confirm what cataract surgery coverage includes in your state.

Can I have cataract surgery at any eye surgery center, or does it have to be Medicare-approved?

The facility must be Medicare-approved for Medicare to pay. Most hospitals and established surgery centers are approved. Your eye doctor's office can tell you which facilities near you accept Medicare for cataract surgery. If you choose a non-approved facility, Medicare will not cover any of the cost.

Will Medicare pay if I need cataract surgery on both eyes?

Yes. Medicare covers cataract removal on both eyes. Most surgeons operate on one eye first, wait a week or two for it to heal, then operate on the other eye. Each surgery is covered separately, and you pay 20 percent of the approved cost for each eye.

What if something goes wrong during surgery and I need a longer hospital stay?

If complications require an overnight hospital stay, Medicare Part A (hospital insurance) covers the inpatient care. You would pay your Part A deductible and any applicable copays for the hospital stay. Discuss this possibility with your surgeon beforehand so you understand what could happen.
