Medicare Part B covers cataract surgery, but you pay a share of the cost

Medicare Part B covers the surgery itself — the procedure to remove a clouded lens and usually replace it with an artificial one. You pay 20 percent of the approved amount after you meet your Part B deductible for the year. The surgeon, facility, and anesthesia are all covered under the same benefit, so you do not pay separately for each piece.

The catch is that Medicare covers only a standard intraocular lens (IOL) — the replacement lens inserted during surgery. If you choose a premium lens designed to reduce your need for glasses afterward, you pay the full difference out of pocket. That difference typically runs $500 to $3,000 per eye, depending on the lens technology and your surgeon's pricing.

Coverage applies whether you have the surgery at a hospital outpatient department or an ambulatory surgery center. Both settings are treated the same way for cost-sharing purposes.

Key Takeaways

  • Medicare Part B pays for the cataract surgery procedure and a standard intraocular lens after you meet your annual deductible.
  • You pay 20 percent of the Medicare-approved amount for the surgery; the exact dollar amount depends on your surgeon and location.
  • Premium lens upgrades that reduce dependence on glasses are not covered and cost $500 to $3,000 per eye out of pocket.
  • Your eye doctor must be enrolled in Medicare for you to receive coverage; confirm this before scheduling surgery.
  • Medigap or Medicare Advantage plans may cover some or all of your 20 percent cost-share, depending on your specific plan.

What happens before surgery: the eye exam and referral

Before Medicare will cover surgery, your eye doctor must document that cataracts are affecting your vision enough to warrant the procedure. This is not a formal approval process — Medicare does not require you to request permission beforehand — but the documentation must be in your medical record. Your eye doctor will perform a visual acuity test and note the degree of cloudiness in your lens.

If your eye doctor is a Medicare-enrolled provider, the documentation is handled during your visit. If you see an ophthalmologist or optometrist who does not take Medicare, you will need to pay out of pocket for that visit, and you may need to transfer your records to a Medicare-enrolled surgeon to have the surgery covered.

There is no waiting period. Once your eye doctor determines surgery is medically necessary, you can schedule it whenever you and the surgeon agree.

Your costs at the time of surgery

You owe 20 percent of the Medicare-approved amount for the entire surgical package. In 2024, the approved amount for routine cataract surgery with IOL insertion ranges from roughly $1,200 to $1,600 depending on your geographic area and the facility type. That means your 20 percent share typically falls between $240 and $320 per eye, though the exact figure depends on where you live and where the surgery is performed.

You must have met your Part B deductible ($240 in 2024) before this 20 percent cost-sharing kicks in. If you have not met your deductible yet, you pay the full deductible amount first, then 20 percent of the approved amount for the surgery.

The facility may ask you to pay your estimated share at the time of surgery or send you a bill afterward. Ask the surgeon's office for an estimate before your procedure date so you know what to expect.

Premium lens upgrades and what they cost

A standard monofocal IOL corrects vision at one distance — usually distance vision — and you will still need reading glasses for close work. Premium lenses correct vision at multiple distances or reduce astigmatism without glasses. These include multifocal lenses, accommodating lenses, and toric lenses for astigmatism.

Medicare covers only the cost of the standard monofocal lens. If you choose an upgrade, you pay the difference between what the premium lens costs and what Medicare would have paid for the standard lens. That out-of-pocket cost is yours alone and does not count toward your deductible or out-of-pocket maximum.

Ask your surgeon for the exact price of any premium lens before you decide. Prices vary widely by surgeon and region. Some surgeons bundle the upgrade cost into a single fee; others itemize it separately.

How Medigap and Medicare Advantage affect your bill

If you have a Medigap (supplemental insurance) plan, it may cover some or all of your 20 percent cost-share for surgery. Most Medigap plans cover this coinsurance, though the specific amount depends on which plan letter (A through N) you hold. Check your plan documents or call your Medigap insurer to confirm what cataract surgery coverage you have.

If you have a Medicare Advantage plan, your cost-sharing rules are different. Your plan sets its own copay or coinsurance amount for surgery, which may be higher or lower than the standard 20 percent. Some Medicare Advantage plans cover cataract surgery with little or no cost-share; others require a copay of $200 to $500 or more. Review your plan's summary of benefits or call the plan directly to learn your exact responsibility.

Neither Medigap nor Medicare Advantage covers the premium lens upgrade cost. That remains your responsibility regardless of which supplemental coverage you have.

What Medicare does not cover

Medicare does not cover routine eye exams, eyeglasses, or contact lenses — even after cataract surgery. If you need new glasses because your vision has changed after surgery, you pay for the exam and frames yourself. Some Medicare Advantage plans include a vision benefit that covers an eye exam and glasses allowance, but Original Medicare does not.

Complications that arise during or after surgery are covered under the same Part B benefit if they occur within the global period (usually 90 days after surgery). However, if you develop a new eye condition unrelated to the surgery — such as age-related macular degeneration — that is a separate issue and covered under different rules.

Frequently Asked Questions

Do I need to get approval from Medicare before scheduling cataract surgery?

No. Medicare does not require advance approval. Your eye doctor documents that surgery is medically necessary, and that is sufficient. You can schedule surgery whenever you and your surgeon agree. However, confirm your surgeon is Medicare-enrolled before booking.

What if I have both Medicare and a Medicare Advantage plan?

Your Medicare Advantage plan is your primary coverage for cataract surgery. You follow your plan's rules for cost-sharing and surgeon selection, not Original Medicare's rules. Check your plan documents to see whether your surgeon is in-network and what your copay or coinsurance will be.

Can I have cataract surgery on both eyes at once?

Surgeons typically perform cataract surgery on one eye at a time, usually one to three weeks apart. Medicare covers both surgeries separately, and you pay your 20 percent cost-share for each eye. Ask your surgeon about their standard timing and whether they can schedule both procedures close together.

Will my vision be perfect after surgery?

Most people see better after cataract surgery, but perfect vision is not may provide. Your outcome depends on the health of the rest of your eye and whether you choose a premium lens. A standard lens may leave you needing glasses for reading or distance vision. Discuss realistic expectations with your surgeon before the procedure.

What happens if my surgeon is not enrolled in Medicare?

If your surgeon does not take Medicare, you can still have the surgery, but you pay the full cost out of pocket — Medicare will not reimburse you. Before scheduling, always confirm that your surgeon is a Medicare-enrolled provider. You can search the Medicare provider directory online or call your surgeon's office directly.
