How Much Does Cataract Surgery Cost With Medicare in New Mexico?

Medicare covers it, but not all of it. Here is the bill line by line, what New Mexico's own Medicare claims show the surgeon and the hospital are paid, and the lens decision that can cost more than everything else combined.

The short answer

With Original Medicare, cataract surgery that implants a conventional intraocular lens is covered under Part B. After the Part B deductible, $283 in 2026, you pay 20% of the Medicare-approved amount "to both the facility and the doctor who performs your surgery" (Medicare.gov). Medicare pays the other 80%. If the operation is done in the doctor's office rather than a hospital or surgery center, the 20% applies to the lens and the surgery together.

So the real question is what those approved amounts are. Medicare publishes its claims by state, and New Mexico's 2024 numbers are below. If you are in a Medicare Advantage plan, or picking one for 2027, your cost follows the plan's copays instead. The eight-step guide to comparing 2027 Medicare Advantage plans shows where to find a plan's outpatient-surgery copay and out-of-pocket maximum in its Summary of Benefits.

What's on a cataract surgery bill?

People are often surprised to get two bills. That's because Medicare pays the surgeon and the place where the surgery happens separately, and your 20% applies to each one. Here is every piece, and who pays it under Original Medicare:

Sources: Medicare.gov — Cataract surgery; Medicare.gov — Eyeglasses & contact lenses; CMS Ruling 05-01; CMS physician claims, New Mexico, 2024; CMS outpatient hospital claims, New Mexico, 2024.

The tests before surgery, such as the measurements of your eye used to choose the lens power, are billed as their own Part B services, also at 20%. And if each eye is done on a different day, each one is its own surgery with its own pair of bills.

What does Medicare actually pay in New Mexico?

National cost articles tend to repeat one figure for the whole country. Medicare's own claims files let us look at New Mexico alone. In 2024, 39 surgeons billed Original Medicare for standard cataract removal with a lens implant (code 66984) in a hospital or surgery center setting, for 5,884 New Mexico patients. The average approved amount for the surgeon was $787. For the more involved version (code 66982), used for 629 patients, it was $869 (CMS Physician & Other Practitioners by Geography and Service, 2024).

Sources: CMS Medicare Physician & Other Practitioners by Geography and Service (2024; CPT 66984, 66982, 66821); CMS Medicare Outpatient Hospitals by Geography and Service (2024; APC 5491). New Mexico rows. Original Medicare claims only.

The facility side is harder to pin down. Hospital outpatient departments in New Mexico billed Medicare for 635 patients in the payment group that holds standard cataract surgery ("Level 1 Intraocular Procedures"), at an average approved amount of $1,781 (CMS Outpatient Hospitals by Geography and Service, 2024). That group also holds a few other eye operations, and CMS doesn't publish the cataract code alone for New Mexico, so treat $1,781 as a close guide rather than an exact price.

Two things stand out. First, 635 is far fewer than the 5,884 people who had the surgery, which suggests most New Mexico cataract operations on Original Medicare happen in ambulatory surgery centers rather than hospital departments. Surgery centers are paid on their own Medicare schedule, so ask the center for its approved amount. Second, the hospitals' average billed charge for that group was $17,235. That number is not what Medicare pays and not what you owe; your 20% is figured on the approved amount.

A caveat on all of these: they are 2024 averages from Original Medicare claims. Medicare's rates change each year, your surgeon's exact figure depends on how the case was billed, and people in Medicare Advantage plans are not in these files.

A worked example for one eye

Take a standard operation at a New Mexico hospital outpatient department, using the 2024 averages above, for someone on Original Medicare with no supplement:

1. Surgeon: 20% of $787 ≈ $157.
2. Hospital outpatient facility: 20% of $1,781 ≈ $356.
3. Total: about $514 for that eye if you already met the deductible this year.
4. If this is your first Part B bill of 2026: the $283 deductible comes first, so roughly $797.

The second eye adds another round of 20% but no second deductible in the same calendar year. Add the 20% on your pre-surgery measurements and follow-up visits outside the surgical package, and on the glasses afterward. You also keep paying the Part B premium, $202.90 a month for most people in 2026 (CMS). The most useful thing you can do is ask the surgeon's office and the facility for their Medicare-approved amounts in writing before the date is set.

Does Medicare cover lens upgrades?

Medicare covers a conventional lens, the kind that restores distance vision, so most people still need reading glasses afterward. Many practices also offer lenses that correct for reading distance (multifocal or "presbyopia-correcting") or for astigmatism ("toric").

You can choose one, and Medicare still pays its share of the standard operation. Under CMS Ruling 05-01, a beneficiary "may request insertion of a presbyopia-correcting IOL in place of a conventional IOL," and is responsible for the part of the facility's and surgeon's charges that is above the charge for a conventional lens (CMS Ruling 05-01). Ruling 1536-R applies the same rule to astigmatism-correcting lenses (CMS Ruling 1536-R). You can also be charged for the extra fitting and vision testing those lenses need (CMS guidance, 2012).

That difference isn't a Medicare-covered cost, so a Medigap policy won't pay any of it, and Medicare Advantage plans generally treat it the same way. The practice sets the price. Ask for it per eye, in writing, and ask what it includes.

Is laser cataract surgery extra?

Not for the standard parts of the operation. In 2012 CMS wrote that "Medicare coverage and payment for cataract surgery is the same irrespective of whether the surgery is performed using conventional surgical techniques or a bladeless, computer controlled laser." The incision, the opening of the lens capsule and the breaking up of the cloudy lens, "by whatever method, may not be charged to the patient" (CMS memo on laser-assisted cataract surgery).

Where a laser is used with a premium lens, the practice can charge only for the non-covered parts tied to that lens. If a quote shows a "laser fee" on top of a standard-lens operation, ask the office which non-covered service it pays for.

Medigap, Medicare Advantage or Medicaid: what changes

The 20% above is what Original Medicare alone leaves you. Most people have something else that changes it:

Sources: Medicare.gov — Cataract surgery; CMS Ruling 05-01; CMS CY2027 Landscape file (Bernalillo County, our count).

With Medigap, the plan letter decides how much of the 20% is left. Plan G, for example, pays the 20% after you meet the Part B deductible; the Plan G vs. Plan N comparison for New Mexico shows where Plan N can leave a small copay.

With Medicare Advantage, look in the plan's Summary of Benefits under outpatient surgery. Some plans list one copay for an ambulatory surgery center and a different one for a hospital outpatient department, which can steer where you have it done. Cataract surgery is also one of the procedures plans often require approval for in advance; our post on prior authorization in New Mexico Medicare Advantage plans explains how that works.

Glasses and the laser touch-up later

Glasses. Medicare doesn't usually pay for glasses, with this one exception: after each cataract surgery that implants a lens, Part B covers one pair of glasses with standard frames, or one set of contact lenses. You pay 20% after the deductible, "any additional costs for upgraded frames," and the glasses must come from a supplier that participates in Medicare (Medicare.gov). Our post on Medicare and eye exams and glasses in New Mexico covers the rest of Medicare's vision rules.

The later laser. Months or years after surgery, the thin capsule behind the new lens can cloud over; some people call it a "secondary cataract." A quick laser treatment (code 66821) clears it, and Part B covers it at 20% like other outpatient care. In New Mexico in 2024, 1,899 Original Medicare patients had it done in a doctor's office, at an average approved amount of $327 (CMS, 2024).

Surgery planned for 2027? Check your plan first

Open Enrollment runs through December 7, 2026, and many New Mexico Medicare Advantage plans end on December 31, including most of Presbyterian's (see the guide to the Presbyterian plans ending). If you expect cataract surgery next year, check these before you choose a 2027 plan:

1. Your eye surgeon. Is the ophthalmologist, not just the clinic, in the 2027 network?
2. Where it would happen. Is the surgery center or hospital they use in network, and what is the plan's copay at each?
3. Prior authorization. Does the plan require approval? If you already have one from a 2026 plan, read whether a prior authorization transfers to a new plan.
4. Both eyes. If the second eye falls in the new year, the copay and deductible may apply again.
5. Eye drops. The drops after surgery go through the plan's Part D drug list. Check their tier.
