Cataract surgery is the most commonly performed surgery in the United States, with roughly 4 million procedures done each year. The operation removes the clouded natural lens of the eye and replaces it with a clear artificial intraocular lens (IOL). It typically takes under 20 minutes per eye and is done as an outpatient procedure, meaning the patient goes home the same day.
The bill for cataract surgery has two parts: the surgeon's professional fee and the facility fee. Where the surgeon operates determines the facility fee, and that choice produces the widest cost swings. An ASC charges roughly half of what a hospital outpatient department charges for the same facility services, and Medicare's payment schedule reflects that exact split. In 2026, Medicare pays $1,255.73 to an ASC versus approximately $2,370 to a hospital outpatient department for the facility component alone. Medicare beneficiaries with Part B should confirm whether Medicare covers cataract surgery before scheduling. Compare costs to a routine eye exam, which is billed separately.
This guide covers 2026 cash prices without insurance, Medicare payment rates for both the surgeon and facility, the premium lens upgrade question, what the No Surprises Act requires providers to give you before surgery, and the most common billing errors on cataract surgery claims. Patients approaching their deductible late in the year may want to time elective cataract surgery to maximize their coverage.
Cataract Surgery Cost by Site of Service in 2026
The biggest cost driver of Cataract Surgery is the site of service: where the procedure is performed. 2026 CMS price transparency data confirms a 2-3x billing differential between independent centers and hospital outpatient departments.
Cataract Surgery prices without insurance vs. 2026 Medicare rates| Site of Service | Range Without Insurance | 2026 Medicare Rate |
|---|
| Ambulatory Surgery Center (ASC) | $3,500 to $5,500 per eye | $1,256 facility + $463 surgeon |
| Hospital Outpatient Department (HOPD) | $4,500 to $7,000 per eye | ~$2,370 facility + $463 surgeon |
| Ophthalmology office (office-based surgery suite) | $2,500 to $5,000 per eye | Varies, typically non-facility PFS |
| Inpatient hospital (rare; complex cases only) | $6,000 to $12,000+ per eye | Bundled in DRG |
2026 Medicare rates: surgeon fee per CMS Physician Fee Schedule final rule; ASC facility fee per CMS OPPS/ASC final rule (CMS-1834-FC). HOPD rate estimated at 1.88x ASC per CMS-published payment ratios. Without-insurance ranges reflect FAIR Health Consumer and hospital price transparency data.

Why the Same Procedure Is So Much More at a Hospital
The facility fee gap between an ASC and a hospital outpatient department exists because hospitals carry overhead costs that ASCs do not: 24-hour emergency capacity, inpatient wings, large administrative structures, and complex billing departments. Congress has required Medicare to pay hospitals more per procedure to offset these structural costs, but that same payment differential shows up in what uninsured and commercially insured patients pay.
For routine cataract surgery on a healthy adult, there is no clinical reason to choose a hospital outpatient department over a well-equipped ASC. Both settings are equipped with phacoemulsification technology and sterile surgical suites. ASCRS data shows that ASC cataract outcomes are equivalent to hospital settings for uncomplicated cases. Your surgeon can typically operate at both types of facilities.
Patients choosing an ASC can save 30 to 50 percent on facility fees. For a Medicare beneficiary, the difference in 20% coinsurance is roughly $223 per eye ($251 vs. $474 in coinsurance on the facility fee alone). Over two eyes, that is $446 in direct savings just from choosing the right facility.
Cataract Surgery Cost by Lens Type
The largest out-of-pocket variable after surgery location is intraocular lens (IOL) type. Medicare covers a standard monofocal IOL. If you choose a premium lens (one that corrects astigmatism or reduces dependence on reading glasses), you pay the difference between the premium IOL and the standard covered IOL. Surgeons must document patient choice for premium lenses and bill the upgrade separately.
Typical cost by variant| Lens Type | Coverage | Typical Out-of-Pocket Upcharge |
|---|
| Standard monofocal IOL | Medicare covered | $0 additional |
| Toric IOL (astigmatism correction) | Upgrade not covered | $500 to $1,500 per eye |
| Multifocal IOL (near + distance) | Upgrade not covered | $1,500 to $3,000 per eye |
| Extended depth-of-focus (EDOF) IOL | Upgrade not covered | $1,000 to $2,500 per eye |
| Laser-assisted (FLACS) upgrade | Not covered | $500 to $1,000 per eye |
Medicare covers the surgery and a standard monofocal IOL regardless of which premium upgrade you choose. The upcharge is only the difference. Ask your surgeon for an itemized breakdown before agreeing to any upgrade.

What Medicare Pays for Cataract Surgery
In 2026, Medicare Part B covers medically necessary cataract surgery, including the surgeon's fee and a standard monofocal IOL. The surgery must be performed on an outpatient basis (ASC or hospital outpatient department) for Part B coverage. Your share is 20% coinsurance after the $283 annual Part B deductible. For one eye at an ASC: you pay roughly $251 in facility coinsurance plus $93 in surgeon coinsurance, totaling approximately $344 per eye after deductible, assuming no Medigap plan. For both eyes, expect around $600 to $700 total under standard Medicare.
If you have a Medicare Supplement (Medigap) plan, it typically covers the 20% coinsurance, leaving you little or no out-of-pocket cost for the surgery itself. Medicare Advantage plans cover cataract surgery but may require prior authorization and network restrictions. Check with your plan before scheduling to confirm your specific cost-sharing. Note that the 2026 Medicare physician payment for CPT 66984 dropped by 11% from 2025 (from $521 to $463), the largest single-year reduction in 30 years, so some ophthalmology practices may be adjusting their scheduling priorities.
What Factors Affect Cost
- Site of service: ASC vs. hospital outpatient department. Biggest cost driver. ASCs typically charge 30 to 50 percent less in facility fees.
- Lens type: standard monofocal (Medicare-covered) vs. premium toric, multifocal, or EDOF lens (patient-pay upgrade of $500 to $3,000 per eye).
- Laser-assisted vs. traditional phacoemulsification. FLACS (femtosecond laser) adds $500 to $1,000 per eye and is not covered by Medicare or most insurers.
- One eye vs. both eyes. Surgeries are typically scheduled weeks apart. Each eye generates a separate bill with its own deductible and coinsurance implications.
- Geographic region. Urban markets and coastal states tend to have higher facility and surgeon fees.
- Whether you have insurance and your deductible status at the time of surgery.
- Case complexity. A complicated cataract (CPT 66982) involving a small pupil, previous eye surgery, or a traumatic cataract is billed at a higher rate. Make sure any upgrade from 66984 to 66982 is documented in your chart.
Common Cataract Surgery Billing Errors
Cataract surgery generates two separate bills (facility and professional), multiple bundled codes, and a premium lens upgrade structure that creates multiple billing friction points. These are the errors most worth checking:
- Upcoded to complex cataract (66982) without documented complexity. If your surgeon billed 66982 but your chart notes do not describe a complicating factor (small pupil, Fuchs' dystrophy, prior vitrectomy, etc.), you may owe significantly more than you should.
- Diagnostic tests billed on the date of surgery. OCT scans, corneal topography, and visual field tests performed the same day as cataract surgery are bundled into the surgical code and should not appear as separate line items.
- Premium lens upgrade billed as covered. The standard IOL implant is covered by Medicare; only the price difference above the standard lens is patient responsibility. If you chose a standard lens, a premium lens line item on your bill is an error.
- Both eyes billed as a single surgical event. Cataract surgery on each eye is billed separately on separate dates of service. If both eyes appear on the same claim date, the second claim will be denied. The patient should not be billed the denied amount.
- Anesthesia billed incorrectly. Cataract surgery typically uses topical anesthesia (eye drops), which is included in the surgical fee. General anesthesia or monitored anesthesia care (MAC) should only appear on your bill if actually administered and medically necessary.
- No Good Faith Estimate provided. Under the No Surprises Act, any provider or facility must give you a written Good Faith Estimate before a scheduled procedure if you are uninsured or self-pay. If surgery was at an ASC or hospital outpatient and your actual bill is $400 or more above the Good Faith Estimate, you can dispute the bill through HHS.
Frequently Asked Questions
How much does cataract surgery cost without insurance in 2026?
Without insurance, cataract surgery costs $3,500 to $7,000 per eye in 2026, with a national average around $5,000. The bill has two parts: a surgeon fee and a facility fee. Choosing an ambulatory surgery center (ASC) over a hospital outpatient department typically saves 30 to 50 percent on the facility portion. Always ask for a cash-pay or self-pay rate, as many ASCs offer discounts for uninsured patients.
What does Medicare pay for cataract surgery in 2026?
In 2026, Medicare pays $462.94 to the surgeon (Physician Fee Schedule rate for CPT 66984) and $1,255.73 to the ASC facility. At a hospital outpatient department, the facility payment is approximately $2,370. Your share is 20% coinsurance after the $283 Part B annual deductible. For an ASC procedure on one eye, expect to pay approximately $340 to $360 out of pocket for a standard cataract with a monofocal IOL.
Is cataract surgery cheaper at an ASC than at a hospital?
Yes, consistently. Medicare pays $1,255.73 to an ASC facility versus approximately $2,370 to a hospital outpatient department for the same cataract surgery in 2026, a gap of roughly $1,114. That gap translates to $223 in extra coinsurance per eye for Medicare patients. For uninsured patients, the cash-price difference is larger: ASCs typically charge $3,500 to $5,500 per eye while hospitals charge $4,500 to $7,000.
Does Medicare cover premium lens upgrades (toric or multifocal IOLs)?
Medicare covers the standard monofocal IOL that restores functional vision. Premium lenses (toric IOLs that correct astigmatism, multifocal IOLs that reduce glasses dependence, and EDOF IOLs) are optional upgrades. Medicare pays its standard amount for the surgery, and you pay the cost difference between the premium lens and the standard lens. Typical upgrade costs run $500 to $3,000 extra per eye depending on lens type.
What is a Good Faith Estimate for cataract surgery?
Under the No Surprises Act, if you are uninsured or choosing not to use insurance, your provider and the surgical facility must give you a written Good Faith Estimate at least 1 business day before the scheduled surgery. The estimate must itemize expected charges from all providers, including the surgeon, anesthesiologist, and facility. If your actual bill comes in $400 or more above the estimate, you can dispute it through HHS at 1-800-985-3059.
How do I know if I was billed correctly for cataract surgery?
Start with the Explanation of Benefits (EOB) from Medicare or your insurer and compare to your bill. Check that: (1) the procedure code is 66984 for a routine cataract, not 66982 (complex) unless your surgeon documented a complication, (2) no diagnostic tests appear as separate charges for the day of surgery, (3) anesthesia is included unless you received general or monitored anesthesia care, and (4) any premium lens charge matches what you agreed to pay. Upload your bill to a medical bill analyzer for a line-by-line review.
Can cataract surgery be done on both eyes at the same time?
Generally, no. Performing cataract surgery on both eyes the same day is called bilateral simultaneous cataract surgery, and Medicare requires each eye to be done on separate dates of service for separate billing. Most surgeons schedule the second eye 2 to 4 weeks after the first. Each eye generates a separate facility bill and surgeon bill. The Part B deductible applies only once per calendar year, so the second eye in the same year avoids the $283 deductible if already met.
What happens if my cataract surgery bill is much higher than expected?
First, compare the bill to the 2026 Medicare-approved amounts: $462.94 for the surgeon and $1,255.73 for an ASC facility. If you were billed at a hospital outpatient department, the facility rate is higher (approximately $2,370). If charges exceed these benchmarks significantly, check for the six common errors listed above. If you are uninsured and the bill is $400 or more over your Good Faith Estimate, file a dispute with HHS. For insured patients, file an appeal with your insurer within the window listed on your EOB.
