Medicare Cataract Surgery Coverage: What Part B Pays and What Premium Lenses Cost You

Medicare Part B generally covers cataract surgery with a standard (conventional) intraocular lens, plus one pair of glasses or one set of contact lenses after each surgery. After the $283 Part B deductible for 2026, you pay 20% of the Medicare-approved amount. What Medicare won't pay for is the upgrade: a lens that also corrects astigmatism or near vision is partly your bill, and that's the part to get in writing before surgery day.

Medicare.gov's Procedure Price Lookup puts the 2026 national average for a routine cataract surgery at $1,717 in an ambulatory surgical center and $2,819 in a hospital outpatient department. Same surgery, same lens, and the patient's 20% share is $343 versus $563. Where the surgery happens matters more than most people expect.

One timing note. The standard Part B premium is $202.90 a month in 2026. CMS had not announced the 2027 premium or deductible when I checked its newsroom on November 12, 2026. If your surgery is scheduled for January or later, the 2027 deductible may differ; the coverage rules below won't. More on what we know about the 2027 Part B premium.

What Original Medicare covers

A cataract is a clouding of the eye's natural lens. The surgery removes that lens and, in most cases, replaces it with a clear artificial one, the intraocular lens or IOL (Medicare.gov). Medicare treats the IOL as a prosthetic device. In CMS's words, a conventional IOL "replaces the distance focusing power of the eye's natural crystalline lens," and it is covered when implanted after cataract surgery (CMS Ruling 1536-R).

That's the key phrase: distance focusing. Medicare's job here is to restore the vision the cataract took away, not to get you out of reading glasses. Everything about the upgrade rules follows from that.

Medicare generally excludes eyeglasses, contact lenses and eye exams done to prescribe them. The exceptions are written right into the regulation: 42 CFR 411.15(b)(2) carves out prosthetic intraocular lenses and "one pair of conventional eyeglasses or contact lenses furnished subsequent to each cataract surgery with insertion of an intraocular lens."

The refraction line trips people up. The test that measures your prescription (the "which is better, one or two?" part) is excluded under 42 CFR 411.15(c) "even when performed in connection with otherwise covered diagnosis or treatment." So your cataract evaluation can be covered while the refraction done at the same visit is billed to you. It may show up as its own charge. Ask at check-in what it costs.

Glaucoma screening is limited to people at high risk: those with diabetes, a family history of glaucoma, African Americans 50 and older, and Hispanic people 65 and older (Medicare.gov).

Surgery center vs. hospital outpatient: the real cost gap

Medicare pays a hospital outpatient department more than an ambulatory surgical center (ASC) for the same cataract operation, and your 20% follows the bigger number. Medicare.gov's Procedure Price Lookup shows national averages based on Medicare's 2026 payments. For CPT code 66984, the routine one-stage cataract removal with lens insertion described in the Claims Processing Manual, ch. 32:

• Facility fee
• Surgeon fee
• Patient pays (20%)

$0$1,000$2,000$3,000

The surgeon's fee is the same national average either way ($462 routine, $630 complex). The whole gap is the facility fee: $1,255 at a surgery center versus $2,357 at a hospital. "Complex" (66982) is the code for cases that need devices or techniques not generally used in routine surgery, like an iris expansion device. Your surgeon decides that, not you.

These are national averages, and prices in your area may differ. Still, if your surgeon operates in both settings, it's a fair question to ask which one you're booked in and why. There can be medical reasons for a hospital setting, so ask rather than assume.

One more cost variable: whether your surgeon accepts assignment. A surgeon who does charges you only the deductible and 20%. A non-participating surgeon who doesn't accept assignment can charge more than the approved amount, in many cases up to 15% more, called the limiting charge (Medicare.gov). I covered that in Part B excess charges.

What you'd pay: a worked example

Hypothetical example using the 2026 national averages above and the $283 deductible. Say this is your first Part B service of the year and you have Original Medicare with no supplemental coverage.

Source: math based on the 20% coinsurance and $283 deductible (Medicare.gov, CMS) and averages from the Procedure Price Lookup. Hypothetical; excludes pre-op visits, the refraction, glasses and any upgrade charges.

The math for one eye at a surgery center: the $283 deductible, plus 20% of the remaining $1,434, which is $286.80, for $569.80 total. Medicare pays the other $1,147.20.

If both eyes need surgery and they're done as separate operations, each one is its own surgery with its own 20%, but you pay the Part B deductible only once a calendar year. That's why scheduling matters: two surgeries in the same year meet one deductible; one in December and one in January meet two, and the January one would be at the 2027 deductible, which CMS hasn't set yet.

Original Medicare has no yearly out-of-pocket cap, so these 20% amounts add up with everything else you use that year. That's the gap a Medigap policy is built to fill.

Standard vs. upgraded lenses

Two CMS rulings set the rules for "premium" lenses, and they're still how claims are handled today. CMS Ruling 05-01 (May 3, 2005) covers presbyopia-correcting IOLs, the multifocal-type lenses meant to give near, intermediate and distance vision. CMS Ruling 1536-R (effective January 22, 2007) applies the same logic to astigmatism-correcting IOLs, often called toric lenses.

The reasoning is the same in both. An upgraded lens does two jobs: it replaces the natural lens (covered) and it does what glasses, contacts or refractive surgery would otherwise do (not covered). CMS's conclusion is that the extra function "does not fall into the benefit category and is not covered." So Medicare still pays its share of what a conventional lens surgery would cost, and you pay the difference.

Source: CMS Ruling 05-01; CMS Ruling 1536-R; Medicare Claims Processing Manual ch. 32, secs. 120 to 120.4.

Three details in the Claims Processing Manual, ch. 32, sec. 120.4 are worth knowing:

• The surgeon and facility may not charge for an upgraded lens unless you request it.
• They may not require you to request one as a condition of doing your cataract surgery. A conventional lens has to remain an option.
• In setting the extra charge, they may take into account the additional work and resources for insertion, fitting, vision acuity testing and monitoring of the upgraded lens, compared with a conventional one.

I won't quote a typical upgrade price; CMS doesn't publish one, and it's set by each practice. Ask for the upgrade charge in writing, per eye, with the facility and surgeon portions listed separately. Then ask a plain question: with a standard lens, what will I likely still need glasses for? A conventional lens is designed to restore distance focus, so the answer usually involves reading glasses. For some people that's a fine trade.

The paperwork for an upgrade (it isn't an ABN)

You may have heard you'll sign an Advance Beneficiary Notice (ABN) for a premium lens. Under Medicare's own manual, that's not the required form. The upgraded-lens function isn't something Medicare might deny; it falls outside any Medicare benefit category. So section 120.3 of the Claims Processing Manual, ch. 32 says the facility and physician "are not required to provide an Advanced Beneficiary Notice" for these lenses.

What they must do, before the procedure, is tell you that Medicare won't pay for services specific to the insertion, adjustment or follow-up of the astigmatism- or presbyopia-correcting function. CMS "strongly encourages" them to use a Notice of Exclusion from Medicare Benefits to spell out exactly which parts are non-payable. If your clinic hands you a different form, read what it lists and ask for the dollar amounts if they're missing.

After surgery, the extra charge shows up on your Medicare Summary Notice as denied, usually with a message like "Medicare does not pay for this item or service." The facility bills Medicare the same procedure code it would use for a conventional lens and reports the upgrade portion with separate codes (V2787 for astigmatism-correcting, V2788 for presbyopia-correcting). Seeing that denial is normal for an upgrade you agreed to. A denial on the cataract surgery itself is not normal, and that one you can challenge through the Medicare appeal process.

Glasses and contacts after surgery

This is the one time Original Medicare pays toward glasses. After each cataract surgery that implants an IOL, Part B covers one pair of eyeglasses with standard frames, or one set of contact lenses (Medicare.gov). You pay 20% of the approved amount after the deductible, plus anything extra for upgraded frames.

• "Each" surgery. Surgery on your right eye in March and your left in May means two separate benefits, per the wording in 42 CFR 411.15(b)(2)(ii).
• Use a supplier that participates in Medicare. Medicare only pays for glasses or contacts from a supplier that participates in Medicare (an enrolled supplier), whether you or the supplier submits the claim (Medicare.gov). Ask the optical shop directly before ordering.
• No replacements. The Medicare Benefit Policy Manual, ch. 15, sec. 120 says replacing these post-cataract glasses or contacts isn't covered. Lose or break them, and the next pair is on you.
• Tinted lenses. UV-absorbing lenses may be covered instead of regular lenses if they're medically necessary for you, but cataract sunglasses on top of regular lenses aren't (same manual section).

Practical tip: if both eyes need surgery a few weeks apart, ask your eye doctor whether to wait until the second eye has healed before filling the prescription. That's a clinical question for them, but it's worth asking before you spend the benefit.

Medigap and Medicare Advantage

Medigap. Cataract surgery is a Part B service, so a Medicare Supplement policy handles its 20% like any other Part B coinsurance. On the Medicare.gov Medigap comparison chart, Plans A, B, C, D, F, G, M and N pay the Part B coinsurance (Plan N can have small office and ER copays), Plan K pays 50% and Plan L pays 75%. Only Plans C and F pay the Part B deductible, and not everyone can buy those. Medigap pays toward Medicare-covered costs. The upgraded-lens portion isn't a Medicare-covered cost, so don't count on a standardized policy to pay it. For the Washington rules, see how Medigap works in Washington and Medicare Supplement insurance in Washington.

Medicare Advantage. A Medicare Advantage plan has to cover all services Original Medicare covers (42 CFR 422.101), which includes medically necessary cataract surgery and the post-surgery glasses. But costs and rules vary by plan: plans can use networks, may require prior authorization for some services, and set their own cost sharing (Medicare & You 2027). Some plans also offer extra routine vision benefits that Original Medicare doesn't (Medicare.gov). Before scheduling, check your plan's Evidence of Coverage, confirm the surgeon and the facility are in network, and ask whether prior authorization is needed.

Help in Washington

If you want someone neutral to look at a quote, a Medicare Summary Notice or a denial, Washington's Statewide Health Insurance Benefits Advisors (SHIBA), part of the Office of the Insurance Commissioner, gives unbiased, confidential Medicare help at no charge. Call 800-562-6900, 8:30 a.m. to 4:30 p.m., Monday to Friday, or use the message form on the SHIBA page. Here's more on how SHIBA works. You can also call 1-800-MEDICARE (1-800-633-4227), TTY 1-877-486-2048.

Before surgery, I'd get four answers in writing: which setting you're booked in (surgery center or hospital), whether the surgeon accepts assignment, which lens you're getting, and the itemized upgrade charge if any. With those, you can work out your own share from the 20% rule. For an overview of coverage options here, see Medicare in Washington.

Your own coverage documents and Medicare's rules decide how any claim is paid. Confirm your situation with a licensed agent, SHIBA, 1-800-MEDICARE or, for legal questions, an attorney.
