Does Medicare Cover Cataract Surgery? Coverage, Cost & Lens Options

Cataract surgery is covered by Medicare if it's medically necessary, and Medicare pays for about 3.8 million surgeries each year. It is one of the most widely performed Medicare surgeries and one of the best performed surgeries for improving quality of life. The Medicare-approved cost minus the 2026 Part B deductible of $283 is covered 80% by Medicare Part B. You will be responsible for the remaining 20% coinsurance, and any additional premium lens upgrades. The national payment for a typical cataract surgery at an ambulatory surgery center is about $1,255, and the actual out-of-pocket costs (deductible + 20% coinsurance) are usually in the range of $200-$800 per eye for a regular cataract surgery. The most important variable cost is your lens. Medicare will pay for the standard monofocal intraocular lens (IOL), which focuses on one distance, while premium lenses such as toric lenses (astigmatism) and multifocal lenses (for both near and distance vision) are elective upgrades. Premium IOLs will cost $2000-$4000 or more per eye out of pocket, not covered by Medicare.

This guide covers Medicare coverage, lens options, costs and what to expect when it comes to cataract surgery. Data are from Medicare.gov, CMS and the American Academy of Ophthalmology. 

When Medicare covers cataract surgery

Medicare only pays for cataract surgery if it is deemed "medically necessary. This indicates that the cataract is impairing vision to such a degree that it is affecting your ability to drive, read, watch TV, work or engage in normal activities. It isn't covered if there is a way to get good vision with corrective lenses alone.Surgery to correct solely for cosmetic reasons is not covered.

Documentation involves best-corrected visual acuity (usually 20/40 or worse) with the addition of glare testing if applicable and functional issues the patient has. Your ophthalmologist must make the assessment face-to-face and record their decision in writing that surgery is necessary. Pre-operative tests will only be performed where clinically necessary for selection of the IOL and surgical planning, usually including biometry (lens power calculation), keratometry, and measurement of the coherence or ultrasound measurement of the eye.

The benefit of the surgery does not include routine refractive testing for new eyeglass prescriptions. Medicare does not usually pay for updated glasses if you need them for reasons other than cataract surgery.

Both eyes may be operated on, but Surgery #2 is usually at least 2-4 weeks after Surgery #1 so that the first eye can heal and stabilize before the second eye is operated on. Medicare will cover both eyes.

What cataract surgery actually involves

Today, a procedure called phacoemulsification can be performed that removes the cloudy natural lens and replaces it with a clear artificial intraocular lens (IOL). The operation is performed without stitches through a small incision and ultrasound to break up and remove the cataract. The majority of patients leave the hospital on the same day and see better within days.

The surgery is carried out in an ambulatory surgical center (ASC) or a hospital outpatient center. Generally, ASCs will be less costly than hospital outpatient centers, but both are also under Part B coverage. The selection of settings will depend on patient health status, surgeon preference and facility availability.

The entire procedure typically takes 15-30 minutes per eye. Local anesthetic, some mild sedation is routine. Recovery time is fairly rapid – most patients return to normal activities within days, but heavy lifting and strenuous activity avoided for several weeks.

However, months or years after surgery some patients develop "secondary cataracts," when the lens capsule becomes cloudy. The treatment is YAG laser capsulotomy, a quick outpatient laser treatment that is also covered by Medicare. The annual fee for the 2026 YAG laser capsulotomy is usually $300 to $500, and the cost will be 20% coinsurance after the AB deductible. 

Standard vs premium intraocular lenses (IOLs)

The most important variable cost in cataract surgery is the selection of IOL. Medicare will fund a standard monofocal IOL, which is a single focal length (usually preselected for seeing at a distance). Most patients will require glasses after surgery for monofocal IOL, usually for reading (but can be for other activities too).

A premium IOL has extra vision features, but it will cost a lot. The toric IOLs are designed to correct astigmatism as well as focusing. Patients that do not require major astigmatism correction can decrease or eliminate their need for glasses for distance vision. The additional costs of toric IOLs are $1,500 to $3,000 each eye, on top of standard surgery fees.

Multifocal and EDOF IOLs can help decrease the need for glasses for distance and near vision. This is an advanced lens that can offer many patients the freedom from the need to wear a pair of eyeglasses in addition to the standard surgery costs and comes in at $2,500–4,000 per eye.

The pricing system is as follows: Medicare will reimburse its standard surgical fee, and the standard monofocal IOL cost (after deductible with 20% coinsurance). With a high-priced IOL, you are charged the increased price difference directly by the surgeon. This “balance billing” for the uncovered refractive component is both legal and commonplace for premium IOL upgrades.

When making a premium IOL appointment, ask your surgical coordinator for a breakdown of the costs that will be covered for the medical procedure and those that will be for elective refractive upgrades. 

Cost breakdown for cataract surgery in 2026

Under Original Medicare for a standard cataract surgery, your 2026 cost structure works as follows.

The 2026 Part B annual deductible of $283 applies once per year before Medicare starts covering its share. If cataract surgery is your first significant Part B service of the year, the first $283 of approved charges come out of pocket.

After the deductible, you pay 20% coinsurance of the Medicare-approved amount for the surgery, IOL, and related services. Medicare pays the remaining 80%. The 2026 national ambulatory surgery center payment rate is approximately $1,255, meaning typical coinsurance is around $250 per eye.

Hospital outpatient department surgery typically costs more than ASC surgery, with Medicare-approved amounts often $1,800-$2,500 per eye. Higher Medicare-approved amounts mean higher 20% coinsurance ($360-$500).

Without insurance, cataract surgery costs $3,000-$7,000 per eye, depending on location, surgeon, and facility. Medicare coverage reduces this dramatically.

Medigap supplement plans cover the 20% coinsurance for cataract surgery, making the procedure essentially free for Medigap policyholders after the Part B deductible is met. This is one of many reasons Medigap is valuable for those who can afford the monthly premium.

If you have a Medicare Advantage plan, your plan must cover cataract surgery at minimum equivalent to Original Medicare, but cost-sharing varies significantly by plan. Some MA plans charge copayments rather than coinsurance, with typical cataract surgery copays of $100-$500 per eye. Network restrictions may apply.

What Medicare covers after cataract surgery

Medicare covers post-surgical follow-up visits and corrective vision support unique to cataract patients.

Medicare uniquely covers one pair of standard eyeglasses or contact lenses per operated eye after cataract surgery with IOL implantation. This is one of the very few situations where Medicare covers vision correction. You pay 20% coinsurance for the glasses or contacts after meeting the deductible. The standard frames are covered, but upgraded frames cost extra.

The glasses/contacts coverage applies once per operated eye, not annually. If your prescription changes years later, you're responsible for the cost of new glasses.

Post-surgical follow-up appointments with your ophthalmologist are covered under Part B. Typical post-op care includes appointments at 1 day, 1 week, and 1 month after surgery, with additional visits as medically necessary.

Eye drops prescribed for healing after cataract surgery (typically antibiotics and anti-inflammatories used for several weeks) are covered under Medicare Part D if you have prescription drug coverage. You pay your Part D plan's standard cost-sharing for these medications.

What Medicare doesn't cover for cataract surgery

Several aspects of cataract care fall outside Medicare coverage. Routine eye exams unrelated to cataract evaluation or other covered eye conditions aren't covered. Annual vision exams for new eyeglass prescriptions, vision screening, or general eye health monitoring without a covered medical condition aren't included.

Premium IOL upgrades (toric, multifocal, extended-depth-of-focus) aren't covered. The cost difference between standard and premium lenses is your responsibility.

Laser-assisted cataract surgery (femtosecond laser) for refractive correction beyond what's medically necessary isn't fully covered. Medicare covers the standard surgical fee, and you pay the additional cost for the laser refractive component.

Cosmetic procedures, such as removing a cataract before it significantly impairs vision for cosmetic reasons (when the patient hasn't reached vision impairment thresholds), aren't covered.

For Medicare coverage of other vision care, Medicare typically doesn't cover routine eye exams, but Medicaid for those who qualify often provides more comprehensive vision coverage.
