Does Medicare Cover Cataract Surgery in Utah? (2026 Costs)

Yes. Cataract surgery with a standard lens implant is one of the most common operations Medicare pays for, and in Utah it is more common than almost anywhere: 4.42% of Utahns in Original Medicare had one in 2024, against 3.07% nationally. Here is what Medicare covers and does not, what the surgeon, the facility and the glasses afterward cost a Utah patient in CMS's own claims data, why the building you have it in changes the bill, and how a Medigap policy or a Medicare Advantage plan changes what you owe.

A cataract is the natural lens of the eye turning cloudy with age, and the National Eye Institute's figure for how common that is bears repeating: “more than half of all Americans age 80 or older either have cataracts or had surgery to remove them.” Surgery is the only treatment, and it works; the same source says nine out of ten people see better afterward. Medicare treats it as the routine, medically necessary operation it is. Medicare.gov's coverage page says Part B covers cataract surgery that “implants conventional intraocular lenses,” and its cost rule is one sentence: “After you meet the Part B deductible, you pay 20% of the Medicare-approved amount to both the facility and the doctor who performs your surgery.” That sentence contains the whole structure of the bill. There are two payees, the surgeon and the building, each sends a claim, each claim carries its own 20%, and the building's share is the larger one by a wide margin. The rest of this article puts Utah numbers on each piece from CMS's own claims files, explains the one exception that costs people real money (the premium lens), and shows how the same surgery looks with a Medigap policy, with no supplemental coverage, and in a Medicare Advantage plan.

What does Medicare cover for a cataract, and what does it not?

The covered list is longer than people expect. Part B pays for the examination that diagnoses the cataract and decides it is ready for surgery (a “medically necessary” eye exam is covered even though a “routine” one is not), the measurement of the eye that selects the lens power, the surgery itself with a conventional monofocal lens, the facility, the anesthesia, the post-operative visits, the laser treatment if the lens capsule clouds over months or years later (a “secondary cataract”), and one pair of eyeglasses or one set of contact lenses after each surgery. Medicare.gov's eyeglasses page is explicit: 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,” and it adds the catch, that “Medicare will only pay for contact lenses or eyeglasses from a supplier that participates in Medicare.”

The not-covered list is short but expensive. Routine eye exams for glasses are not covered; Medicare.gov says flatly that Medicare “doesn't cover routine eye exams (sometimes called 'eye refractions') for eyeglasses or contact lenses,” and that is why the eye exam rows in the table below are for medical exams, not refractions. Glasses outside the post-cataract pair are not covered. And the premium lens upgrade is not covered. Since CMS Ruling 05-01 in 2005, Medicare has paid for a cataract surgery with a presbyopia-correcting lens (a multifocal or accommodating lens that reduces the need for reading glasses) exactly as it pays for one with a conventional lens; the beneficiary “is responsible for payment of that portion of the facility charge” and of the physician's charge “that exceeds” the charge for a conventional lens. A 2007 companion ruling applied the same rule to astigmatism-correcting (toric) lenses, and CMS keeps a list of which lenses count. The ruling also contains two sentences worth knowing by heart: the physician and facility “may not charge for cataract extraction with insertion of a presbyopia-correcting IOL unless the beneficiary requests this service,” and they “may not require the beneficiary to request a presbyopia-correcting IOL as a condition of performing a cataract extraction.” Laser-assisted surgery follows the same logic: Medicare pays the standard rate for the surgery, and a practice may charge for laser work done to correct astigmatism or to implant a premium lens, but not for using the laser to do the covered operation.

What did cataract surgery actually cost Utah patients?

CMS publishes every Original Medicare claim by billing code and by the state of the provider, which lets us see what Utah ophthalmologists were paid in 2024 and therefore what the 20% share came to. The surgeon's fee is the first bill.

Beneficiaries are distinct people with at least one claim for the code in 2024. For the two surgery codes we count the facility-setting row only (surgery performed in a surgery center or hospital outpatient department); the file also has an office-setting row for the standard code (1,034 Utahns, average approved amount far lower), which is consistent with split surgical and post-operative billing and may overlap, so we do not add it. The laser and exam rows sum office and facility settings. Your share assumes the Part B deductible has been met and the provider accepts assignment. Denominators are people with Part B in Original Medicare during 2024 (Utah 183,494; national 27,982,142). Medicare Advantage encounters are not in this file. Sources: CMS, Medicare Physician & Other Practitioners — by Geography and Service, 2024 — data.cms.gov; CMS, Medicare Monthly Enrollment — data.cms.gov.

Three things stand out. First, the surgeon's fee is modest: $670.36 on average, which is less than a quarter of the $2,788.47 Utah surgeons submitted on average, because Medicare's approved amount, not the charge, is what you owe 20% of. Second, Utah's volume is high and rising: 8,104 standard surgeries in 2024 against 7,945 in 2023, up 2.0%, from 148 surgeons billing in a facility setting. Third, the follow-on laser procedure is common. A “secondary cataract,” the clouding of the capsule that holds the new lens, is treated in a few minutes with a YAG laser in the office, and 4,280 Utahns had one in 2024, 2.33% of Part B enrollees against 1.71% nationally. Medicare's 2026 rate for it in a surgery center is $301.90; in a Utah office in 2024 the approved amount averaged $322.43, so your share is about $64.49.

Why does the facility fee depend on the building?

The second bill, from the facility, is where the money is, and Medicare pays two different prices for the same operation depending on where it is done. In its January 2026 payment addenda, CMS sets the national rate for standard or complex cataract surgery at $1,255.73 in an ambulatory surgery center and $2,337.32 in a hospital outpatient department, the group CMS calls “Level 1 Intraocular Procedures.” Your 20% is therefore about $251.15 in a surgery center and $467.46 in a hospital, for an identical procedure and often the same surgeon. CMS's hospital claims file confirms the Utah figure: in 2024, 2,599 Utahns had a Level 1 intraocular procedure in a hospital outpatient department, and the average Medicare-approved facility amount was $2,083.92 (national $2,207.96), of which Medicare paid $1,653.29 and the patient or a supplemental policy owed the rest.

ASC and OPPS rates are national figures before geographic wage adjustment; the Utah hospital average is actual 2024 claims. APC 5491 also includes a small number of other minor intraocular procedures, so the hospital share is approximate.

None of this means a surgery center is better; it means it is cheaper for the person paying 20%, and it is worth asking where your surgeon operates. Most Utah ophthalmology groups along the Wasatch Front and in St. George use freestanding surgery centers; a hospital outpatient department is the usual choice for patients with health conditions that call for a hospital setting and in rural counties where the hospital is the only facility. If you hold a Medigap policy the setting changes nothing for you, because the policy pays the 20% either way. If you are in Medicare Advantage, the plan's Evidence of Coverage will list two different copays, one for “ambulatory surgical center” and one for “outpatient hospital,” and the gap between them is often as large as the gap in Medicare's own rates.

How does Utah compare with the nation on cataracts and cataract surgery?

Utahns on Medicare are not more likely to have a cataract than other Americans, but they are more likely to have it treated. The CDC's Vision and Eye Health Surveillance System, which reads every Original Medicare claim, found that 38.06% of Utahns 65 and older in Original Medicare had a cataract diagnosis on a 2022 claim, against 37.49% nationally, essentially the same; the age-related cataract figure was 22.99% in Utah and 23.17% nationally. But 20.44% of Utah seniors carried a treated cataract diagnosis against 19.1% nationally, and 17.62% an untreated one against 18.39%. CMS's surgery claims say the same thing from the other direction.

Utah runs 1.44 times the national rate for standard cataract surgery, 1.52 times for complex surgery and 1.36 times for the YAG laser afterward, and 30.1% of Utahns in Original Medicare had a comprehensive medical eye exam in 2024 against 26.2% nationally. Two cautions. The file counts people by the state of the provider, so it includes out-of-state patients treated in Utah and excludes Utahns treated elsewhere, and it covers Original Medicare only, so none of the 269,226 Utahns in Medicare Advantage in June 2026 (54.9% of the state's 490,235 beneficiaries) is in it. The likeliest explanations for the gap are the ordinary ones: Utah's retirees are active, drive long distances and want their vision back; the state has a dense supply of cataract surgeons along the Wasatch Front and in St. George; and the National Eye Institute's list of cataract risk factors, age, “a lot of time in the sun,” smoking and diabetes, includes a sun-and-altitude item that Utah, with the nation's highest melanoma rate, has in abundance. Our skin cancer and Medicare guide covers that side of Utah's sun.

Which Utah counties have the most vision trouble?

CMS does not publish cataract surgery by county, but the CDC does estimate, for every county, the share of adults who are blind or have serious difficulty seeing even with glasses. Cataract is the most treatable cause on that list, and the counties at the top are the rural ones farthest from a surgeon.

Adults 18 and older, all causes of vision loss, age-adjusted model-based estimates from the 2023 Behavioral Risk Factor Surveillance System; small-county estimates have wide confidence intervals. 24 of 29 counties are at or above 4.0%. Source: CDC PLACES, county data, 2025 release — data.cdc.gov.

San Juan, Piute, Carbon, Sanpete, Duchesne and Uintah lead the state, and every one of them is at least an hour from the cities where most cataract surgeons practice. The Wasatch Front counties, Weber, Salt Lake, Utah and Davis, sit at or below the state's middle, and the high-income mountain counties, Summit, Wasatch and Morgan, are lowest. For a rural reader the practical consequence is that “the cost of cataract surgery” includes two round trips to Provo, Richfield, St. George or Salt Lake City, one for the exam and measurements and one for each eye, and that a Medicare Advantage HMO's network needs to include a surgeon within reach.

Can you find a Utah cataract surgeon who takes Medicare?

Yes, nearly all of them do. CMS's clinician file lists 203 clinicians with a Utah practice location whose primary specialty is ophthalmology, and 198 of them, 98%, accept assignment, meaning they take the Medicare-approved amount as payment in full. The other 5 are non-participating and may charge up to 15% more than the approved amount, an “excess charge” that Medigap Plan G pays and Plan N does not. The state's 298 Medicare-enrolled optometrists (280 accepting assignment) do most of the diagnosing and much of the post-operative care, and an optometrist's medical eye exam is covered the same way an ophthalmologist's is. With Original Medicare you need no referral to see either.

Clinicians whose primary specialty in the CMS file is ophthalmology, counted once per clinician per city; a surgeon who practices in two cities appears under both, so the column does not sum to 203. Source: CMS, Doctors and Clinicians National Downloadable File — data.cms.gov.

How do you actually use the eyeglasses benefit?

This is the part of cataract coverage that goes to waste. After each surgery that implants a lens, Medicare pays 80% of one pair of glasses with standard frames, or one set of contact lenses. In 2024 the average Medicare-approved amount in Utah was $77.46 for the frames and $45.65 to $80.58 per lens depending on whether it was single-vision, bifocal or trifocal, so a complete pair of bifocals came to about $182.42 approved and $36.48 at 20%. You pay the full extra cost of designer frames, anti-glare coatings or progressive lenses on top of that, but the base pair is covered.

The catch is the supplier rule. Medicare pays only an optical shop that is enrolled in Medicare as a durable medical equipment supplier, and most retail and online opticians are not. CMS's supplier claims show the result: 358 Utahns received Medicare-covered frames in 2024 from 72 enrolled suppliers, about 4.4 pairs for every 100 standard cataract surgeries in the state, against 8.8 per 100 nationally. Some of the gap is people who chose a premium lens and need no glasses, and some is Medicare Advantage members using a plan's eyewear allowance instead, but most of it is people who bought glasses at a shop that could not bill Medicare. Ask your surgeon's office which optical shops near you are enrolled, or use Medicare.gov's supplier directory, before you buy. Our dental, vision and hearing guide covers what Medicare Advantage vision benefits add.

How do Medicare Advantage and Medigap each handle cataract surgery?

More than half of Utah's Medicare population, 269,226 of 490,235 people in June 2026, is in a Medicare Advantage plan. Those plans must cover cataract surgery, but on their own terms: a specialist copay for the exam, a copay or coinsurance for the surgeon, a separate and usually larger copay for the facility that differs between a surgery center and a hospital, an in-network surgeon, a referral in most HMOs, and in most plans prior authorization before the surgery date is set. Many plans add what Original Medicare lacks, a routine eye exam and an eyewear allowance, and some waive the cost-sharing on the post-surgery glasses. The in-network out-of-pocket limit caps the year. The premium-lens upgrade is not covered by any Medicare Advantage plan either.

In Original Medicare with a Medigap policy, each bill, surgeon, facility, laser, glasses, is 20% after the deductible, and the policy pays the 20%. Plan G pays everything but the $283 deductible, including any excess charge from one of the 5 non-participating ophthalmologists; Plan N pays everything but the deductible, a copay of up to $20 for office visits, and leaves you with excess charges. Outpatient surgery carries no Plan N copay. There is no network, no referral and no prior authorization, and you may choose any surgeon and any facility. The 221,009 Utahns in Original Medicare with no Medigap policy are the ones paying the figures in this article out of pocket, and for two eyes in a hospital that is well over a thousand dollars. Our Plan G versus Plan N and Medicare Advantage versus Medigap guides lay out the trade-offs.

An Ogden example: two eyes, one autumn

Consider a 72-year-old retired railroad machinist in Weber County in Original Medicare. Night driving on 12th Street has become a problem of halos and glare. His optometrist's medical exam finds cataracts in both eyes and refers him to one of the 15 ophthalmologists listed in Ogden and South Ogden, who measures both eyes, schedules the right eye at a surgery center in October and the left in November, and recommends a standard monofocal lens set for distance with reading glasses afterward. At 2024 Utah average surgeon's fees and the January 2026 national surgery-center rate, the Medicare-approved amounts look like this:
