Medicare Coverage for Cataract Surgery: What Is Covered and What Costs Extra

Cataract surgery is the most commonly performed surgical procedure in the United States, and the majority of those procedures are performed on Medicare beneficiaries. Medicare covers cataract surgery comprehensively, but within defined limits that leave room for significant additional charges if you want upgraded technology. Understanding exactly what Medicare does and does not cover before you schedule the procedure prevents surprise bills and lets you make informed choices about optional upgrades.

Bryce's Take

The upgrade conversation at cataract surgery catches people off guard. You go in for a fully covered procedure and the surgeon mentions a premium lens that will eliminate the need for reading glasses. Suddenly there is an out-of-pocket cost of $2,000 per eye that Medicare does not cover. That is not a ripoff, the technology is real and the benefit is real. It is an informed choice, not an automatic add-on, and the basic lens is completely covered if you prefer.

What Medicare Part B covers

Medicare Part B covers cataract surgery as an outpatient procedure, including the surgical removal of the cataract, the implantation of a basic intraocular lens (IOL), the pre-operative evaluation, and routine post-operative follow-up care for 90 days. The procedure can be performed at a hospital outpatient department or an ambulatory surgical center. After your Part B deductible, Medicare pays 80% and you pay 20% of the Medicare-approved amount. With Medigap Plan G or N, that 20% is covered and your out-of-pocket is minimal or zero for the covered components.

The basic IOL: what Medicare provides

The intraocular lens that Medicare covers is a monofocal lens, a basic, fixed-focus implant that corrects vision at one distance (typically distance vision). Most patients with a monofocal lens still need reading glasses after surgery. The monofocal lens is safe, effective, and has been used successfully for decades. Medicare's coverage of this standard lens is complete, there is no cost to you for the basic IOL beyond standard cost-sharing.

Premium lens upgrades: what Medicare does not cover

Ophthalmologists offer several premium IOL options beyond the basic monofocal lens. These include toric lenses that correct astigmatism, multifocal lenses that provide both distance and near vision, extended depth of focus lenses, and accommodating lenses. Medicare does not cover the additional cost of these premium lenses, you pay the difference between the Medicare-approved amount for a standard lens and the total cost of the premium lens. This upgrade cost typically runs $1,000 to $3,000 per eye. The decision to upgrade is entirely optional.

Laser-assisted cataract surgery: an important distinction

Traditional cataract surgery uses ultrasound to break up the lens (phacoemulsification). Laser-assisted cataract surgery uses a femtosecond laser for some of the surgical steps. Medicare covers cataract surgery using standard techniques. The laser-assisted portion is considered an advanced technology upgrade and is not covered by Medicare. If your surgeon offers laser-assisted surgery, the additional cost for the laser component is yours to pay out of pocket. This is distinct from standard laser eye surgery (LASIK), which Medicare does not cover at all.

One pair of eyeglasses after cataract surgery

Medicare covers one pair of eyeglasses or contact lenses following cataract surgery in which an IOL is implanted. This is one of the few situations where Medicare covers eyewear. The glasses must be from a Medicare-enrolled optical supplier. The standard 80/20 cost-sharing applies. If you elect a premium lens and your vision is corrected to the extent that you no longer need glasses at a particular distance, you may choose not to use this benefit.

Ambulatory surgical center versus hospital outpatient

Cataract surgery can be performed at either a hospital outpatient department or a Medicare-certified ambulatory surgical center. The cost-sharing may differ between settings. Hospital outpatient costs under Medicare's outpatient payment system may be higher than ASC costs under the ASC payment schedule, though your 20% coinsurance applies to the approved amount in either setting. If cost is a concern, ask your surgeon whether the procedure can be performed at an ASC.
