Does Medicare cover eye exams in Arizona?

Not routine ones. Original Medicare does not pay for the yearly eye exam whose purpose is a new glasses or contact lens prescription, and it does not buy the glasses. Medicare.gov puts it in six words: “You pay all costs for non-covered services.” What Part B does pay for is the eye care that is medical. A yearly diabetic eye exam. A yearly glaucoma test if you are at higher risk. Tests and injections for macular degeneration. Cataract surgery, and one pair of standard glasses afterward. For each of those you pay 20% of the Medicare-approved amount after the $283 Part B deductible. The confusion comes from the fact that both kinds of exam happen in the same chair, at the same practice, sometimes on the same afternoon.

In north Peoria this is a live question every fall. Vistancia and Trilogy hold a lot of households who arrived in the last few years with a Medicare Advantage plan bought in another state, or with an employer vision plan that ended at retirement, and who now discover that the eye doctor along Lake Pleasant Parkway wants to know which of their two cards to bill. Add a desert sun that the ophthalmologists here will tell you ages a lens faster than a Michigan one, and an eye exam stops being a formality. Here is what Medicare pays, where the rest comes from, and what to settle before the 2027 plans open on October 15.

What Original Medicare covers at the eye doctor

Vision care is not a separate Medicare benefit. Part B covers “medically necessary” doctor services, and each line below turns on whether there is a medical reason for the visit.

Source: Medicare.gov coverage pages for routine eye exams, eyeglasses and contact lenses, glaucoma screenings, eye exams for diabetes, and macular degeneration. Federal rules, identical in Peoria, Anthem and everywhere else. A Medicare Advantage plan must cover everything on the "Yes" lines, at its own copays and inside its own network.

The four medical exams Part B does pay for

Diabetes. If you have diabetes, Part B covers an eye exam for diabetic retinopathy once a year, done by an eye doctor legally allowed to perform it in Arizona. This is the one that matters most and gets skipped most. Retinopathy has no symptoms until it is advanced, and the yearly dilated exam is how it gets caught while it is still treatable.

Glaucoma. Part B covers a glaucoma screening once every 12 months if you are at higher risk, and Medicare.gov defines higher risk as having diabetes, having a family history of glaucoma, being African American and 50 or older, or being Hispanic and 65 or older. In Maricopa County that last line covers a great many people, and most of them do not know the screening is theirs to claim. If you already have glaucoma, the pressure checks and field tests that manage it are covered as treatment of a diagnosed condition, not as screenings, so the once-a-year limit does not apply.

Macular degeneration. Part B may cover diagnostic tests and treatment for age-related macular degeneration, including the injectable drugs that treat the wet form. Those injections are given in the office or in a hospital outpatient department, and in the second case you also pay a separate facility copayment. On Original Medicare with a Medicare Supplement, Plan G picks up the 20% on the drug, the doctor and the facility. On a Medicare Advantage plan, ask what the cost-sharing is for Part B drugs given in the office, because a course of injections every few weeks makes that copay the most important number in the plan.

Cataracts. Cataract surgery with a conventional lens is covered as surgery, not as vision care, and it is the one time Original Medicare buys eyeglasses: one pair with standard frames, or one set of contacts, after each surgery that implants a lens, from a supplier that participates in Medicare. I went through the whole procedure, the lens upgrade that is billed to you and the referral step on Advantage plans in the cataract surgery post.

There is one more exam most people forget. The “Welcome to Medicare” preventive visit, available once in your first 12 months on Part B, includes what Medicare.gov calls “a simple vision test.” It is an eye chart, not an eye exam, and it costs nothing if the provider accepts assignment. Its job is to flag a problem that then justifies a covered medical visit.

Why one appointment can be both covered and not covered

Almost every eye care bill I am asked about comes down to a single line item: the refraction. That is the part of the exam where the doctor flips lenses and asks which looks clearer, and it produces the glasses prescription. Medicare excludes exams “for eyeglasses or contact lenses,” and the refraction is exactly that, so practices bill it separately. You can have a fully covered diabetic retina exam and still owe a modest charge for the refraction done in the same chair. It is not a billing error. It is Medicare working as written.

Two things follow from that.

The reason for the visit is what gets billed. An appointment booked because you have diabetes, because your mother had glaucoma, because something changed in one eye, or because the primary care doctor sent you is a medical visit under Part B. An appointment booked as “my yearly eye exam” by someone with no diagnosis and no symptom is a routine visit, and a practice that expects Medicare to deny it may ask you to sign an Advance Beneficiary Notice accepting the bill. Tell the scheduler the truth in useful detail. “I have diabetes and I am due for my retina check” books a different appointment from “I need new glasses,” and for a great many people over 65 the first sentence is the accurate one.

A Supplement does not change any of this. Plan G and Plan N pay Medicare’s gaps on services Medicare covers. They cannot turn an excluded service into a covered one, so the refraction and the routine exam are yours on a Supplement just as they are on Original Medicare alone. I hear “but I have Plan G” about this more than about any other exclusion, and the what Medicare does not pay for explainer has the full list of places that sentence does not help.

Optometrist versus ophthalmologist does not decide coverage, by the way. Medicare pays either for covered services, as long as the doctor is licensed for the service in Arizona and accepts Medicare. What decides it is why you are there.

Where routine vision coverage actually comes from

If Original Medicare pays nothing toward the routine exam and the glasses, three places do.

A Medicare Advantage plan. This is where most Peoria households get it. KFF’s analysis of the 2026 plan year found that more than 99% of people in individual Medicare Advantage plans are in a plan that offers eye exams, glasses or both. That figure says nothing about how much the benefit is worth, which ranges from a routine exam with no eyewear money at all to an annual allowance that covers a reasonable pair of frames and lenses, and it says nothing about where you can use it. Both of those are in the plan’s Evidence of Coverage, not on the mailer.

A standalone dental, vision and hearing policy. For people on Original Medicare with a Supplement, a separate policy fills the gap without disturbing the medical coverage they chose the Supplement for. These are not Medicare products, and the useful comparison is the annual premium against what you would actually spend on exams and glasses in a year, which for many people is a closer call than the marketing suggests. It is worth a quote and a candid look, and I would rather tell you it is not worth it than sell you one that is not.

Your own pocket. A routine exam and a pair of glasses is a known, budgetable cost for a lot of retirees, and choosing to pay it rather than reshape a medical plan around it is a perfectly sound decision. The point of this post is that it should be a decision and not a surprise.

Reading an Advantage plan’s vision benefit properly

Four things decide what a vision benefit is worth, and the front of the plan brochure tells you at most one of them.

1. The network. Vision benefits usually run through a vision vendor with its own provider list, separate from the plan’s medical network. Your ophthalmologist being in network for a glaucoma visit does not mean the same office is in the vision network for a routine exam, and the retail optical chains along Bell Road and Happy Valley Road are in some vision networks and not others. Check the office you would actually drive to, against the vision list specifically.
2. The allowance. Is it a dollar amount toward frames and lenses, a fixed copay for a defined pair, or a discount? Does it cover contacts instead of glasses? A benefit that reads well as a headline can be a discount card once you get to the fine print.
3. The frequency. Exam once a year, eyewear once a year or once every two years. An unused annual allowance generally does not carry over.
4. The medical side. The diabetic exam, the glaucoma screening and the macular degeneration injections are covered by the plan’s medical benefit at its specialist copay, not by the vision benefit. Ask what that copay is, and whether the plan needs a referral to get you into the ophthalmologist. Many HMO plans in Maricopa County do, and I covered how to tell in the referral post.

The same reading applies to the hearing and dental lines, which I covered in the hearing aids post and the dental post. Plans make their quiet adjustments in exactly these supplemental benefits, which is why the Annual Notice of Change is worth reading rather than filing.

The Peoria part of this

The new arrivals. The 85383 corridor is full of households who moved here in the last few years. If you came on a Medicare Advantage plan from another state, the plan itself probably had to change, and if you came from an employer plan with a vision rider, that rider is gone. Either way you are establishing with a new eye doctor and a new vision network at the same time, and the Arizona sun means the first exam here matters more than the last one there did.

The seasonal residents. Trilogy and Westbrook Village both hold people who spend the summer somewhere cooler. On Original Medicare with a Supplement, a covered eye visit can happen with any eye doctor in the country who accepts Medicare, and a standalone vision policy generally travels with you. On most Advantage plans, a routine exam has to be used inside the vision network, and a glaucoma or macular follow-up outside the Arizona medical network is not covered unless it is urgent. If you get injections every six weeks and you are in Minnesota from May to October, that is the whole Advantage versus Supplement decision in one appointment.

The seam. ZIPs along the Peoria–Glendale–Sun City line sit close enough together that neighbors a mile apart are offered different plan line-ups, and the vision benefits on those line-ups differ too. Sun City in particular has eye practices built almost entirely around Medicare patients, and a great many north Peoria households end up there for retina and glaucoma care whichever side of the city line they sleep on. Price your own ZIP and check your own eye doctor rather than borrowing the answer from the community association. Medicare in Peoria and Medicare in Glendale have the local picture on each side.

The long-timers. In 85345 and Westbrook Village I more often talk to people who have seen the same ophthalmologist for fifteen years. For them the vision allowance is a footnote. The only question that matters at plan-change time is whether that doctor, at that office, stays in the medical network for 2027, and it deserves a phone call rather than an assumption.

What to do between now and December 7

The calendar is on your side right now, which is not true for most of the year.

The caution I give every year applies here with extra force: do not choose a medical plan because of its vision benefit. A pair of glasses is a few hundred dollars every year or two. Your ophthalmologist, your hospital and your prescriptions are what you live with every week, and the macular degeneration injections that a plan covers at a high copay will cost more in one quarter than a vision allowance saves in a decade. If routine vision is the gap, a standalone policy fills it without disturbing anything else. The plan type finder is a six-question start if you are not sure which structure suits you.

The short version

• Original Medicare does not cover routine eye exams or ordinary glasses. Medicare.gov: “You pay all costs.”
• Part B does cover the medical exams: a yearly diabetic eye exam, a yearly glaucoma screening if you are at higher risk, macular degeneration tests and treatment, and any exam for a specific eye problem. You pay 20% after the $283 deductible.
• Cataract surgery is covered, and so is one pair of standard glasses after it. That is the only time Original Medicare buys eyeglasses.
• The refraction is billed separately and is not covered, even at an otherwise covered visit. A Supplement does not pick it up.
• Being Hispanic and 65 or older counts as higher glaucoma risk on Medicare’s own list, which puts a yearly covered screening within reach of a large share of Maricopa County.
• Routine vision coverage comes from an Advantage plan, a standalone policy or your own pocket. More than 99% of individual Advantage plan enrollees are in a plan offering something, and what that something is worth is in the Evidence of Coverage.
• In north Peoria, check the vision network separately from the medical network. The office on Lake Pleasant Parkway can be in one and not the other.

If you would rather have someone check it for you

Pulling the vision schedule out of every plan offered at your address, checking which eye doctors the vision network and the medical network each reach, and telling you whether a standalone policy would be the simpler answer is about a twenty-minute conversation with someone who does it weekly. There is no charge for it, and I would rather tell you your current plan already handles this than have you switch for nothing. None of this is medical advice. If something has changed in one eye, book the appointment first and sort out the billing second.

The office is in Anthem, roughly 25 minutes from north Peoria out the Carefree Highway and down Lake Pleasant Parkway, and most of this gets done by phone anyway. Call (602) 844-6002 or book a time. By calling or texting you agree to be contacted about your Medicare options; there is no cost and no obligation.

Bring your plan’s Evidence of Coverage if you have it. The vision benefit is usually a few pages in, and it is never as simple as the number on the front.
