If you have Original Medicare, your out-of-pocket cost for standard cataract surgery is usually the Part B deductible plus 20% of the Medicare-approved amount for covered services. For 2026, Medicare’s national cost data for routine cataract surgery shows an average patient payment of about $343 at an ambulatory surgical center and $563 at a hospital outpatient department. Those figures are national averages for the procedure and can change by location, provider, facility, and the exact services you receive.
The 2026 Medicare Part B annual deductible is $283. If you have not yet met that deductible when you have surgery, some or all of it may be added to what you owe. Supplemental insurance, including certain Medigap policies, may pay some or most of the remaining Medicare cost sharing.

How Much Does Cataract Surgery Cost With Medicare in 2026?
Medicare Part B generally covers medically necessary cataract surgery that removes the cloudy natural lens and replaces it with a conventional intraocular lens, or IOL. Under Medicare’s cataract surgery coverage rules, you normally pay 20% of the Medicare-approved amount after meeting the Part B deductible.
For CPT code 66984, a common code for routine cataract removal with insertion of an intraocular lens, the 2026 Medicare Procedure Price Lookup gives the following national averages:
| Setting | Medicare-approved total | Average patient payment |
|---|---|---|
| Ambulatory surgical center | $1,717 | $343 |
| Hospital outpatient department | $2,819 | $563 |
These numbers include the facility and doctor fees shown in Medicare’s national estimate for this procedure. They are not a guaranteed quote for your surgery. Anesthesia, additional procedures, diagnostic testing, postoperative treatment, or services billed separately can change the final amount.
Does the $283 Part B Deductible Get Added to the Cataract Surgery Cost?
Possibly. The Centers for Medicare & Medicaid Services set the 2026 Part B deductible at $283.
If you already satisfied the Part B deductible earlier in 2026, you generally do not pay it again for cataract surgery. Your main Original Medicare responsibility would normally be the applicable 20% coinsurance and any non-covered charges.
If you have paid none of your deductible, however, your immediate out-of-pocket expense could be higher than the $343 or $563 national procedure estimate.
For example, someone having routine cataract surgery at an ambulatory surgical center who has not met any of the Part B deductible should not simply assume that “$343 is the final bill.” The deductible, separate covered services, and any optional non-covered upgrades all have to be considered.
Why an Ambulatory Surgical Center May Cost Less
The facility is one of the largest variables in Medicare cataract surgery costs. Medicare’s 2026 national figures for CPT 66984 show a substantially lower approved amount at an ambulatory surgical center than at a hospital outpatient department.
Medicare Part B covers facility fees for approved procedures performed at participating ambulatory surgical centers. Under Medicare’s ambulatory surgical center coverage guidance, patients generally pay 20% of the Medicare-approved amount after satisfying the Part B deductible.
This does not mean an ASC is appropriate for every patient. Your ophthalmologist may recommend a particular setting because of your medical needs, the complexity of the procedure, anesthesia requirements, or other factors. Cost is one part of the decision, not the only part.
Standard IOL vs Premium Lens Costs
One of the easiest ways for a cataract surgery estimate to jump is through an optional lens upgrade.
Original Medicare covers cataract surgery with a conventional intraocular lens when coverage requirements are met. However, Medicare does not necessarily pay for the extra functionality of lenses designed to correct presbyopia or astigmatism beyond the conventional lens benefit.
CMS guidance allows a beneficiary who chooses certain presbyopia-correcting or astigmatism-correcting IOLs to pay the additional charges attributable to those non-covered features. In other words, Medicare can still pay its portion of the covered cataract procedure while you pay separately for the elective upgrade.
Before choosing a premium IOL, ask for the estimate to be divided into:
- the Medicare-covered cataract surgery amount,
- your Medicare deductible and coinsurance,
- the additional lens upgrade charge,
- extra testing associated specifically with the premium lens, and
- any other non-covered professional or facility fees.
This separation makes it much easier to see which expenses result from Medicare cost sharing and which result from an elective upgrade.
Does Medicare Cover Laser Cataract Surgery?
The use of a laser does not automatically make an otherwise covered cataract procedure ineligible for Medicare. Medicare’s current benefits publication states that, when cataract surgery is covered in your area, the procedure may be performed using traditional surgical techniques or lasers.
The important distinction is what Medicare considers part of the covered cataract procedure versus an optional service associated with refractive correction or another non-covered feature. CMS has specifically addressed additional beneficiary charges associated with certain premium IOL functions and laser-assisted cataract surgery.
Ask the surgeon to identify any laser-related charge that you would be expected to pay yourself and explain why that particular service is not included in the Medicare-covered procedure.
Anesthesia Can Add Another Medicare Cost
Cataract surgery commonly involves anesthesia services. Medicare Part B covers qualifying outpatient anesthesia services, but after the Part B deductible you generally owe 20% of the Medicare-approved anesthesia amount. A facility copayment may also apply depending on where the procedure is performed.
For that reason, an estimate based solely on the cataract procedure code may not represent every charge appearing on your final Medicare Summary Notice.
What About Glasses After Cataract Surgery?
Original Medicare normally does not cover routine eyeglasses. Cataract surgery creates an important exception.
Part B covers one pair of eyeglasses with standard frames or one set of contact lenses after each cataract surgery that implants an intraocular lens. After the deductible, you generally pay 20% of the Medicare-approved amount. You are responsible for extra costs associated with upgraded frames or other non-covered options.
There is another important condition: the glasses or contact lenses must come from a Medicare-participating supplier for Medicare to pay. For a closer look at this benefit, see our guide to Medicare glasses after cataract surgery.
Pre-Surgery Eye Exams and Refraction May Be Billed Differently
Do not assume every eye-related service surrounding cataract surgery receives identical Medicare treatment. Medicare distinguishes covered medical eye care from routine vision services, and refraction can have different coverage rules.
If you are trying to understand a separate examination charge, read our explanation of Medicare eye exams versus medical eye exams and the guide to Medicare refraction coverage.
Patients who notice a major difference in focus between their two eyes while waiting for second-eye surgery may also find our guide to anisometropia after cataract surgery useful.
How Medigap Can Change Your Out-of-Pocket Cost
If you have Original Medicare plus Medigap, your personal cost can be very different from the amounts paid by someone with Original Medicare alone.
Depending on the Medigap plan and when you became eligible for Medicare, the policy may cover some Medicare-approved coinsurance and other cost sharing. It generally does not transform an elective premium-lens feature into a Medicare-covered benefit, so you should still ask separately about non-covered upgrade charges.
Check the specific benefits of your Medigap policy rather than assuming that “supplemental insurance” means every cataract-related expense will be paid.
Medicare Advantage Cataract Surgery Costs Work Differently
The $343 and $563 examples above are Original Medicare national averages. They should not be treated as your Medicare Advantage copay.
A Medicare Advantage plan must provide Medicare-covered benefits, but its cost-sharing structure, provider network, referral requirements, prior authorization rules, and supplemental vision benefits can differ from Original Medicare.
Before scheduling surgery, contact the plan or review the Evidence of Coverage and ask for the expected cost for the surgeon, facility, anesthesia provider, and any required diagnostic services. Also confirm that each provider involved is treated as in-network when the plan uses networks.
A Simple Example of Cataract Surgery Out-of-Pocket Costs
Suppose you have Original Medicare and undergo a standard routine cataract procedure at an ambulatory surgical center. Medicare’s 2026 national estimate for CPT 66984 shows an average patient payment of $343.
If you have already met your Part B deductible and have no other coverage, that $343 figure provides a useful starting point for the Medicare-covered procedure. Your actual amount can still differ.
If you have not met the $283 deductible, your total responsibility may be higher. If you also choose a premium IOL with non-covered refractive features, those upgrade costs would be added separately. Additional covered or non-covered services could change the bill again.
This is why “$343 cataract surgery with Medicare” should be read as a national estimate for a particular covered procedure and setting, not as an all-inclusive price guarantee.
What to Ask Before Cataract Surgery
A written estimate is more useful when each component is identified separately. Before the procedure, consider asking the surgeon’s office these questions:
- Is the surgeon enrolled in Medicare and does the surgeon accept Medicare assignment?
- Will the surgery take place in an ambulatory surgical center or hospital outpatient department?
- What CPT code is expected to be billed for the procedure?
- What is the estimated Medicare-approved amount?
- What facility fee will I owe?
- Will anesthesia generate a separate bill?
- Is the proposed IOL a conventional Medicare-covered lens or a premium upgrade?
- Which portions of the quote are not covered by Medicare?
- Are postoperative visits included in the surgical payment or separately billed?
- What should I expect to pay after my Medigap or Medicare Advantage coverage is applied?
Bottom Line
For standard cataract surgery under Original Medicare, the basic calculation starts with the Part B deductible and typically 20% coinsurance on Medicare-approved covered services.
For 2026, Medicare’s national estimate for routine cataract surgery under CPT 66984 shows an average patient responsibility of approximately $343 in an ambulatory surgical center versus $563 in a hospital outpatient department. The annual Part B deductible is $283.
Your actual out-of-pocket cost can be lower if supplemental insurance pays the Medicare cost sharing, or considerably higher if you choose non-covered premium lens features or receive additional separately billed services. The most useful number is therefore not a national average alone, but a written estimate that separates the Medicare-covered procedure from every elective or non-covered charge.
