Mayo Clinic Arizona insurance questions come up constantly — Mayo in Scottsdale and Phoenix is one of the top reasons people choose to stay in Arizona for their healthcare. But here’s what a lot of people don’t find out until they’re already sitting in the waiting room with the wrong coverage: not every health plan gets you in the door. Here’s exactly what does — and doesn’t — work.
Mayo Clinic Arizona Insurance: The Short Answer
Original Medicare + a Medicare Supplement (Medigap) — accepted at Mayo Clinic Arizona, no exceptions.
Medicare Advantage — Mayo Clinic does not accept non-contracted Medicare Advantage plans. If you’re on one, don’t assume you’re covered.
ACA Marketplace plans (Ambetter, Blue Cross Blue Shield, Cigna, Oscar, UnitedHealthcare Marketplace) — not accepted at Mayo Clinic Arizona as of 2026.
Private off-exchange PPO plans (like UHC Choice Plus or Aetna Open Choice PPO) — accepted, but these are underwritten plans you buy directly, not subsidized Marketplace plans.
If You’re on Medicare: The Plan G vs. Plan N Detail That Matters at Mayo
Mayo Clinic Arizona accepts Original Medicare and any Medicare Supplement carrier — that part is straightforward. But there’s a detail specific to the Arizona location that trips people up: unlike Mayo’s Florida campus, Mayo Clinic Arizona does not accept full Medicare Assignment. That means they’re allowed to bill up to 15% above what Medicare approves — what’s called an “excess charge.”
This is exactly where the choice between Medigap Plan G and Plan N actually matters. Plan G covers those excess charges in full. Plan N does not — so if you’re a Plan N holder being treated at Mayo Clinic Arizona, you could see a bill for that difference. I’ve written a full breakdown of Plan G vs. Plan N in Arizona if you want the complete comparison, but if Mayo Clinic access matters to you specifically, that excess-charge detail alone is often reason enough to choose Plan G.
You’ll also need a referral to be seen at Mayo, and in some cases prior authorization for specific tests or procedures — standard Medicare rules, not something unique to Mayo.
Why Medicare Advantage Is the Riskiest Choice Here
Mayo Clinic’s own guidance is direct: they do not accept non-contracted Medicare Advantage plans. If you’re 65+ and want reliable access to Mayo, a Medicare Advantage plan puts that access at the mercy of whatever network your specific carrier has negotiated — and that can change year to year. I don’t sell Medicare Advantage, and this is one of the clearest real-world examples of why: here’s the full explanation.
If You’re Under 65: The ACA Marketplace Doesn’t Get You In
This is the one that catches people off guard. None of the individual ACA Marketplace plans sold in Arizona for 2026 — not Ambetter, not Blue Cross Blue Shield, not Cigna, not Oscar, not UnitedHealthcare’s Marketplace plans — are accepted at Mayo Clinic Arizona. Banner|Aetna and BCBS Statewide PPO, which used to offer some access, are no longer on the ACA Marketplace at all as of 2026.
To get Mayo Clinic access under 65, you generally need a private, off-exchange PPO plan — options like UHC Choice Plus or Aetna’s Open Choice PPO network are commonly accepted. These aren’t Marketplace plans, so there’s no subsidy, and most are medically underwritten, meaning your health history affects your rate and whether you qualify at all. That’s a real tradeoff: broader network access in exchange for underwriting and no tax credit.

If you’re turning 65 in Arizona in the next year, you’ve probably already gotten a stack of mail from insurance companies — and maybe a few phone calls you didn’t ask for. Here’s the thing: this decision only has one real do-over window, and it closes fast. Let’s walk through exactly what you need to do, in order, so you don’t miss anything.
Your 7-Month Window: The Initial Enrollment Period
Medicare gives you a seven-month Initial Enrollment Period (IEP) built around your 65th birthday: three months before, your birthday month, and three months after. This is your one guaranteed shot to sign up without medical underwriting or penalties.
Enrolling in the three months before your birthday month means your coverage starts the day you turn 65. Wait until later in the window, and your start date pushes back — sometimes by months. That gap matters if you’re relying on Medicare to replace coverage you’re losing.
Are You Enrolled Automatically, or Do You Have to Apply?
This trips up more people than anything else. If you’re already receiving Social Security retirement benefits at least four months before you turn 65, Medicare Parts A and B kick in automatically — your card shows up in the mail about three months before your birthday, no action needed.
If you haven’t started Social Security yet, enrollment is not automatic. You have to apply yourself through the Social Security Administration at ssa.gov or by calling 1-800-772-1213. Miss this step and you can end up without coverage on your birthday.
Still Working? You Might Be Able to Delay — But Check First
If you’re still working at 65 and covered by an employer group plan (yours or a spouse’s), you may be able to delay Medicare enrollment without penalty, as long as that employer coverage counts as “creditable” — meaning it’s considered at least as good as Medicare’s. This is worth confirming with your employer’s benefits department before you assume you’re covered.
Get this wrong and it’s expensive: go 63 days or more without creditable drug coverage, and Medicare charges you a Part D late enrollment penalty for the rest of your life. Not a one-time fee — permanent, added to every monthly premium going forward.
The Big Decision: Medigap or Medicare Advantage?
Once you’re enrolled in Original Medicare (Parts A and B), you’ll choose how to fill the gaps — Medicare pays roughly 80% of covered costs, and something needs to cover the rest. You have two paths, and they work very differently:
Medicare Supplement (Medigap) pairs with Original Medicare. Any doctor or hospital that accepts Medicare — anywhere in the country — is in-network. No referrals, no prior authorizations, no network to worry about.
Medicare Advantage replaces Original Medicare with a private plan, usually built around a specific network of doctors and hospitals. Premiums are often lower or $0, but you’re limited to that network, and switching back to Medigap later isn’t guaranteed — insurers can medically underwrite you outside your Initial Enrollment Period.
I don’t sell Medicare Advantage, and I’ve written about exactly why on this page if you want the full explanation. In Arizona, Plan G is the most popular Medigap option — I’ve broken down how it compares to Plan N in this comparison if you’re trying to decide between the two.
Your Turning 65 in Arizona Checklist
3 months before your birthday month: Confirm whether you’re auto-enrolled (already on Social Security) or need to apply yourself.
Check employer coverage: If you’re still working, confirm with your benefits department whether your drug coverage is “creditable” so you avoid the Part D penalty.
Decide: Medigap or Medicare Advantage? This is the decision that’s hardest to undo later — worth getting right the first time.
Compare Medigap carriers. Plan G coverage is federally standardized, so the letter is identical everywhere — but premiums between carriers can differ by $50–$100 a month for the exact same plan.
Enroll before your window closes. Miss your 7-month IEP and you’re waiting for the General Enrollment Period (January–March), possibly with a lifetime penalty attached.
Frequently Asked Questions
When do I need to enroll in Medicare after turning 65 in Arizona?
You have a 7-month Initial Enrollment Period — three months before your birthday month, your birthday month, and three months after. Enrolling in the three months before your birthday month means your coverage starts exactly on your 65th birthday.
Am I automatically enrolled in Medicare when I turn 65?
Only if you’re already receiving Social Security retirement benefits at least four months before you turn 65 — in that case, your Medicare card arrives automatically about three months before your birthday. If you haven’t started Social Security yet, you must apply yourself through the Social Security Administration.
Can I delay Medicare if I’m still working at 65?
Yes, if you’re covered by a qualifying employer group health plan. But confirm with your employer’s benefits department that the coverage is considered “creditable” — otherwise you risk a permanent Part D late-enrollment penalty if you go 63 days or more without creditable drug coverage.
What’s the difference between Medigap and Medicare Advantage in Arizona?
Medigap (Medicare Supplement) pairs with Original Medicare and lets you see any doctor or hospital that accepts Medicare, anywhere in the country, with no referrals or networks. Medicare Advantage replaces Original Medicare with a private network-based plan — often lower premiums, but limited to that network, and switching back to Medigap later isn’t guaranteed.
What happens if I miss my Initial Enrollment Period?
You’ll need to wait for the General Enrollment Period (January–March), and you may face a permanent Part B premium penalty for each year you were eligible but didn’t enroll.
How I Can Help
I’ve been helping people turning 65 in Arizona since 2004. When you call, I spend about five minutes learning your situation, then I go research quotes across multiple Medigap carriers — not just one company’s price. You get a detailed, side-by-side quote by email, and you review it on your own time. No pressure to decide on the call.
Plan G vs Plan N — when choosing a Medicare Supplement plan in Arizona, this is the comparison that matters most. Both plans are popular. Both cover most of what Original Medicare leaves behind. However, they handle office visits and cost-sharing differently. In this guide, you’ll see exactly how Plan G vs Plan N compares — so you can choose the right plan for 2026.
What Plan G and Plan N Both Cover
First, it helps to know what these two plans share. Both Plan G vs Plan N cover the following:
Medicare Part A coinsurance and hospital costs
Medicare Part A deductible ($1,676 in 2026)
Medicare Part A hospice care coinsurance
Skilled nursing facility coinsurance
Medicare Part B coinsurance — with one key difference explained below
Foreign travel emergency care up to plan limits
In addition, both plans require you to pay the Part B deductible ($257 in 2026) once per year. After that, coverage kicks in. So far, they look nearly identical. The differences, however, matter a lot depending on how often you use your insurance.
Plan G vs Plan N: The Key Differences
Plan G covers 100% of your Medicare Part B coinsurance. Therefore, after your Part B deductible, you owe nothing for covered outpatient care.
Plan N covers most Part B coinsurance — but not all. Specifically, Plan N has these out-of-pocket costs:
Up to $20 copay per office visit
Up to $50 copay per emergency room visit (waived if admitted)
Part B excess charges — if a doctor doesn’t accept Medicare assignment, you pay the difference between their rate and Medicare’s approved amount
Most Arizona doctors accept Medicare assignment. As a result, excess charges rarely come up. However, the office visit copays do add up if you see doctors often. That’s the core of the Plan G vs Plan N decision.
How Premiums Compare in Arizona
Plan N typically costs $20–$40 less per month than Plan G in Arizona. Therefore, over a full year, you could save $240–$480 in premiums with Plan N.
However, that savings only holds if your copays stay below the premium difference. For example, if you visit the doctor six times per year, that’s up to $120 in Plan N copays. In that case, Plan N still wins on price. On the other hand, frequent visits or ER trips can close the gap quickly.
The bottom line: run the numbers for your situation. That’s exactly what I do for clients at no charge.
Who Should Choose Plan G
Plan G makes the most sense in these situations:
You have ongoing health conditions or frequent doctor visits
You want predictable costs with no copay surprises
You travel often and may see out-of-network providers
You simply want the most comprehensive coverage available
In short, Plan G is the “set it and forget it” option. After your Part B deductible, your costs are done for the year.
Who Should Choose Plan N
Plan N works well in these situations:
You are generally healthy and see a doctor only a few times per year
You want to lower your monthly premium
Your doctors all accept Medicare assignment
You are comfortable paying a small copay at visits
Furthermore, Plan N is a smart choice for people who want solid Medigap coverage without paying for benefits they rarely use.
Plan G vs Plan N: Carriers in Arizona
Both plans are standardized by the federal government. Therefore, the benefits are identical no matter which insurance company you buy from. What differs between carriers is the monthly premium and the company’s rate history.
Whether you choose Plan G or Plan N, timing is critical. When you first enroll in Medicare Part B, you receive a 6-month Medigap open enrollment window. During this period, insurance companies cannot deny you or charge more based on health history.
After this window closes, however, insurers can use medical underwriting. Consequently, pre-existing conditions could affect your options or your premium. This window only happens once. Therefore, if you’re turning 65, get your Medigap plan in place before your birthday month.

Medicare Advantage plans — also called Medicare Part C — are heavily marketed to Arizona seniors every fall. The ads make them sound like a no-brainer — low premiums, extra benefits, simple coverage. However, after more than 20 years helping Arizona residents navigate Medicare, I’ve seen the disadvantages of Medicare Advantage plans up close. Here are 9 things the ads don’t tell you.
1. Disadvantages of Medicare Advantage: Narrow Provider Networks
One of the biggest disadvantages of Medicare Advantage is the restricted network. Most plans only cover care from in-network providers. If your doctor isn’t in the plan’s network, you pay out-of-pocket — or find a new doctor.
Original Medicare lets you see any doctor in the U.S. who accepts Medicare. That’s the vast majority of physicians. Medicare Advantage plans can’t say the same.
2. Prior Authorization Requirements
Before Medicare Advantage pays for many procedures, the insurance company must approve them first. This process — called prior authorization — can delay care by days or weeks. In some cases, approval is denied entirely.
According to Medicare.gov, Original Medicare does not require prior authorization for most services. Your doctor decides what care you need, and Medicare covers it.
3. Higher Out-of-Pocket Costs When You’re Sick
Medicare Advantage plans often advertise low or zero premiums. However, when you actually use the plan, costs can add up quickly. Copays for specialist visits, hospital stays, and procedures can push your annual out-of-pocket costs to $8,000–$10,000 or more.
With a Medicare Supplement (Medigap) Plan G, your only cost is the Part B deductible — $257 in 2026. After that, you pay nothing for covered services the rest of the year.
4. Plans Change Every Year
Medicare Advantage plans can change their benefits, networks, copays, and drug formularies every January 1st. A plan that worked well for you in 2025 may look very different in 2026. Your doctors may drop out of the network. Your medications may no longer be covered at the same cost.
Medigap plans are standardized and stable. Plan G benefits are set by the federal government and don’t change from year to year.
5. The One-Way Door Problem
This is the most serious of all disadvantages of Medicare Advantage that most people don’t discover until it’s too late. If you enroll in Medicare Advantage and later want to switch to a Medigap supplement plan, you may need to pass medical underwriting.
Insurance companies can deny you Medigap coverage — or charge significantly higher premiums — based on your health history. Once you’re locked into Medicare Advantage with serious health conditions, switching may no longer be possible.
6. Limited or No Coverage Outside Your Service Area
Most Medicare Advantage plans only cover non-emergency care within their local service area. If you travel frequently, spend time in another state seasonally, or want access to specialists in other cities, Medicare Advantage can leave you uncovered.
Original Medicare — and any Medigap plan — covers you at any Medicare-accepting provider nationwide. No zip code restrictions.
7. Mayo Clinic and Major Hospitals Often Not Included
Mayo Clinic Arizona does not accept most Medicare Advantage plans. Neither do many other major specialty hospitals. If you’re diagnosed with a serious condition and want access to the best specialists in the country, Medicare Advantage may not get you there.
Original Medicare is accepted at Mayo Clinic and most major medical centers across the U.S.
8. “Extra Benefits” Are Often Overstated
Medicare Advantage plans advertise dental, vision, hearing, gym memberships, and other extras. In practice, these benefits are often limited — small dollar amounts for dental, narrow networks for vision, or gym programs that require specific facilities.
Many people find these add-ons don’t offset the higher costs they face when they need real medical care.
9. Smaller Networks in Rural Arizona
If you live outside the Phoenix metro — in rural Arizona, smaller cities, or communities far from major medical centers — Medicare Advantage networks may offer very few in-network options. Driving long distances to see an in-network provider, or paying out-of-network rates, becomes a regular reality.
Original Medicare works everywhere there’s a Medicare-accepting doctor. In rural areas, that’s often the only practical choice.
What to Consider Instead of Medicare Advantage
Understanding the disadvantages of Medicare Advantage before you enroll can save you from a very difficult situation down the road.
I’m Andy Orlikoff, an independent Medicare broker based in Surprise, AZ. I don’t sell Medicare Advantage. After 20+ years watching what happens when people need their coverage most, I recommend Medicare Supplement Plan G to nearly every client who qualifies.
I’ll compare rates from multiple carriers, explain your options clearly, and help you enroll — at no cost to you. Your premium is the same whether you use a broker or go direct.
As an independent insurance broker helping Arizona retirees since 2004, I’m seeing a clear pattern this year: more people are asking whether they should stay with Medicare Advantage or switch to something better. After reviewing what’s happening with Advantage plans in 2026, I’m recommending Medicare Supplement Plan G to virtually every client who qualifies. Here’s why.
Why I’m Recommending Medicare Supplement Plan G in 2026
Medicare Advantage plans have been losing ground. In 2026, several major carriers cut benefits, raised copays, and reduced networks. According to Medicare.gov, you can switch plans during open enrollment if yours no longer works for you. A JAMA study found that 1 in 10 Medicare Advantage members was forced off their plan entirely. Meanwhile, Medicare Supplement Plan G hasn’t changed — and that stability is exactly what my clients need.
No Prior Authorization With Medicare Supplement Plan G
One of the biggest frustrations I hear from clients on Medicare Advantage is prior authorization. Before you can have a procedure, the insurance company has to approve it. That approval can take days or weeks — and it can be denied.
With Medicare Supplement Plan G, there is no prior authorization. If Medicare covers a service, Plan G pays. The decision stays between you and your doctor, not an insurance company’s claims department.
See Any Doctor in Arizona — and Across the Country
Medicare Advantage plans restrict you to a network. Step outside it and you pay out-of-pocket — or you’re not covered at all.
Medicare Supplement Plan G works with Original Medicare, which means you can see any doctor in the U.S. who accepts Medicare. In Arizona, that matters for a few specific reasons:
Mayo Clinic Scottsdale accepts Original Medicare — and therefore Plan G. Most Medicare Advantage plans are not accepted at Mayo Clinic.
Snowbird protection — many Arizona clients split time between states. Plan G covers you wherever Medicare is accepted. Your Advantage plan likely doesn’t.
No referrals required — you can see a specialist directly, without waiting for a primary care gatekeeper.
Predictable Costs All Year
Medicare Advantage plans advertise low or zero premiums. However, the real costs show up in copays, coinsurance, and out-of-pocket maximums that can reach $8,000–$10,000 per year if you get seriously ill.
With Medicare Supplement Plan G, your only out-of-pocket cost is the Part B deductible — $257 in 2026. After that, you pay nothing for covered services for the rest of the year. No surprise bills. No anxiety about what the mail brings after a hospital stay.
Plan G Rates in Arizona — What to Expect in 2026
Plan G premiums vary by age and carrier. However, as a general benchmark for Arizona:
Age 65: approximately $100–$150/month
Age 70: approximately $130–$190/month
Age 75: approximately $160–$230/month
Rates for the same plan vary significantly between carriers. As a result, comparing quotes from multiple companies before you enroll can save you $50–$100 per month — with identical benefits. That’s exactly what I do for every client.
The One-Way Door: Why Timing Matters
Here’s what most people don’t know: if you enroll in Medicare Advantage and later want to switch to Medicare Supplement Plan G, you may need to pass medical underwriting. That means insurance companies can deny you or charge more based on your health history.
When you first turn 65 and enroll in Medicare Part B, you have a 6-month open enrollment window where no company can deny you Plan G regardless of health. That window only happens once. After it closes, switching becomes much harder — and sometimes impossible.
If you’re turning 65 or newly enrolled in Medicare, get Plan G in place now, while the door is open.
