Cataract Surgery Cost in 2026: What Insurance Covers

Cataract surgery is the most common surgery performed in the United States—more than 4 million procedures each year. For Medicare patients, the out-of-pocket cost can be close to zero for a standard procedure. But the bill can climb to $5,000 or more per eye when premium lens upgrades, laser add-ons, and facility fees enter the picture. This guide breaks down every cost component, explains exactly what Medicare and commercial insurance cover, and shows you how to spot the billing errors that appear in 26% of cataract surgery claims according to BillKarma’s claims data.

1. Cost breakdown: surgeon fee, facility fee, and IOL

A cataract surgery bill typically arrives as two or three separate charges. Understanding each component is the first step to knowing whether you were billed correctly.

The surgeon fee and facility fee are almost always billed separately—you may receive two bills from two different entities. The lens implant device (IOL) itself is bundled into the facility fee and should not appear as a separate line item for a standard monofocal lens. If you see a separate charge for a standard IOL device on your bill, that is a potential double-billing error.

2. What Medicare covers (and what it doesn’t)

Medicare Part B covers cataract surgery as a medically necessary procedure when a physician documents that the cataract is impairing your vision and daily functioning. Coverage applies to both the surgeon fee and the facility fee, and it covers one pair of eyeglasses or contact lenses after the surgery.

Here is how the cost-sharing works under Medicare in 2026:

• Part B deductible: $257 per year. Once met, it applies to all Part B services for the rest of the year.
• Medicare pays: 80% of the Medicare-approved amount for the surgeon and facility.
• You pay: 20% coinsurance. For a combined surgeon plus facility charge with an approved amount of $1,500, that is $300 out of pocket per eye.
• With Medigap: Medigap Plans C, D, F, G, and N cover the 20% coinsurance entirely or in part, reducing your cost to near zero for the base procedure.
• Not covered: Premium IOL lens upgrades, laser-assisted surgery add-ons, and any cosmetic components of the procedure.

If your surgeon does not accept Medicare assignment, they can charge up to 15% above the Medicare-approved amount (called the “limiting charge”). Always ask whether your surgeon accepts Medicare assignment before scheduling to avoid surprise charges.

3. Premium IOL lenses: multifocal, toric, and EDOF

During cataract surgery, the cloudy natural lens is removed and replaced with an artificial intraocular lens (IOL). Medicare and commercial insurance cover a standard monofocal IOL that corrects distance vision. To see at multiple distances or correct astigmatism, surgeons offer premium lens options at an additional cost.

Surgeons are required by Medicare rules to provide patients with a written advance notice (an Advance Beneficiary Notice, or ABN) that explains the premium lens upgrade cost is not covered before you agree to it. If you were not given this notice in writing and were later charged for an IOL upgrade, you have grounds to dispute that charge.

4. Ambulatory surgery center vs. hospital: why it matters

Cataract surgery is overwhelmingly performed as an outpatient procedure, but the type of facility you use has a major impact on your bill. Ambulatory surgery centers (ASCs) are specialized outpatient facilities that handle high-volume procedures like cataract surgery more efficiently than hospital outpatient departments.

For Medicare patients, CMS sets different payment rates for ASCs and hospital outpatient departments. In 2026, Medicare pays roughly $1,050 to an ASC for the facility component of cataract surgery versus $1,400 to a hospital outpatient department for the same procedure. For uninsured patients paying cash, the difference is even more pronounced: hospitals charge 35–50% more than ASCs on average.

ASCs handle the large majority of cataract surgeries safely and with comparable outcomes. Unless your doctor has documented a specific medical reason you need a hospital (severe cardiac or pulmonary disease, high anesthesia risk), an ASC is almost always the more cost-effective setting.

5. CPT codes on your cataract surgery bill

Knowing the CPT codes on your bill lets you look up the Medicare rate for each service and verify you were coded correctly.

6. Common billing errors to look for

BillKarma’s analysis of ophthalmology claims found billing errors in 26% of cataract surgery claims. The most common errors are:

• Upcoding 66984 to 66982: The most frequent error. Some billing departments routinely use the complex code (66982) for all cataract procedures to collect a higher reimbursement. Check your operative note—if the surgeon’s notes describe a routine procedure with no complications or special techniques, billing 66982 is incorrect.
• Billing a premium IOL as a covered standard lens: The facility may bill the base procedure as though a standard lens was used while separately collecting the upgrade fee from the patient. The IOL device code on the claim should reflect what was actually implanted.
• Duplicate biometry charges: Pre-surgical A-scan measurements (CPT 92136) are sometimes billed twice—once in the pre-op office visit and again as a separate line item on the surgery facility bill.
• Unbundling included services: Certain services performed on the same day as cataract surgery (nursing care, post-op monitoring, standard operating supplies) are bundled into the facility fee under Medicare rules. Billing them separately is an unbundling error.
• Wrong eye modifier: Medicare requires a right-eye (RT) or left-eye (LT) modifier on cataract surgery claims. If the modifier is missing or wrong, the claim may pay incorrectly or generate a duplicate-service flag.

7. Action steps before and after surgery

1. Confirm your surgeon accepts Medicare assignment. Call the surgeon’s billing office and ask: “Do you accept Medicare assignment for cataract surgery?” If not, they can charge up to 15% above the Medicare rate. Look for an assignment-accepting ophthalmologist if the extra cost matters to you.
2. Ask whether the facility is an ASC or hospital outpatient department. If your surgeon operates at both, ask which one will be used and get the estimated facility fee for each. For routine cataract surgery, the ASC will almost always cost less.
3. Get the lens upgrade discussion in writing. If you are offered a premium IOL (toric, multifocal, EDOF), get the upgrade cost in writing before surgery. Medicare requires an Advance Beneficiary Notice—if you were not given one, the charge is disputable.
4. Request an itemized bill after surgery. Once you receive the Explanation of Benefits (EOB) from Medicare or your insurer, request the itemized bill from both the surgeon and the facility. Match each charge to a CPT code.
5. Look up the CPT code. Use the BillKarma calculator below to check the Medicare rate for any CPT code on your bill. A markup of more than 3× the Medicare rate on the facility fee is a flag worth disputing.
6. Check for the 66982 upcode. If your bill shows 66982 instead of 66984, call the surgeon’s office and ask for the operative note. If the notes describe a routine procedure, ask the billing department to correct the code.
7. File a dispute in writing if needed. Send a dispute letter to the facility citing the specific CPT codes, the Medicare rates, and any billing errors you found. See our debt dispute guide for a template.
