Medicare’s Annual Enrollment Period (AEP) runs October 15 through December 7, 2026. Any changes you make take effect January 1, 2027. Here’s what AEP actually covers, what’s new for 2026, and why it’s worth a look even if you’re not planning to change anything.
What AEP Actually Covers
AEP is specifically the window for changing Medicare Advantage and Part D prescription drug coverage — joining, switching, or dropping either. It is not the enrollment window for Medicare Supplement (Medigap) plans. Medigap doesn’t have a single national enrollment period the way Advantage and Part D do; you can generally shop for a Medigap plan at any time, though outside your original Medigap Open Enrollment window or a guaranteed-issue situation, carriers can medically underwrite you.
Why AEP Season Still Matters If You Have Medigap
Even though Medigap itself isn’t on the AEP calendar, fall is still the right time to check a few things:
Your Part D drug plan — if you carry a standalone Part D plan alongside Medigap, its formulary and pricing can change every year, so it’s worth reviewing during AEP (I’m not licensed to sell Part D plans myself, but it’s still worth checking on your end or with your Part D agent).
Your Medigap premium — carriers commonly adjust Medigap rates at renewal. If yours went up significantly, it’s worth comparing what else is available, especially if your health has stayed steady since you first enrolled.
Whether Medicare Advantage still makes sense for you — if you’re on an Advantage plan and considering a move to Original Medicare plus Medigap, AEP is when you’d drop the Advantage plan; just know that moving to Medigap afterward may involve medical underwriting unless you qualify for guaranteed issue.
What’s Different for 2026
A few concrete numbers worth knowing this year:
The standard Medicare Part B premium is $202.90/month for 2026, up from $185/month in 2025.
The Part D out-of-pocket cap increased from $2,000 (2025) to a higher indexed amount for 2026, and enrollees can still choose to spread that cost across the year in equal monthly payments instead of paying it early.
Some insurers are exiting the Medicare Advantage market or reducing plan offerings for 2026 — if that affects your current plan, you’ll likely get a notice from your carrier this fall, and it’s worth acting on it rather than setting it aside.
A Few Common Mistakes During AEP
Comparing plans on premium alone, without confirming your doctors and pharmacy are still in-network. Waiting until the first week of December to make a decision, which leaves little room to fix a mistake before the deadline. Assuming a plan that worked well last year hasn’t changed — formularies and networks are re-evaluated annually, not locked in.
How I Can Help
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. I don’t sell Medicare Advantage or Part D plans, so I’m not working an angle when I tell you whether your current Medigap setup still makes sense or not.
I’ve laid out the full turning-65 process in this Medicare checklist, and if Mayo Clinic access matters to your plan choice, I’ve covered exactly which plans keep it in-network in this breakdown.
Frequently Asked Questions
What are the AEP dates for 2026?
Medicare’s Annual Enrollment Period runs October 15 through December 7, 2026. Changes made during this window take effect January 1, 2027.
Does AEP apply to Medicare Supplement (Medigap) plans?
No. AEP covers Medicare Advantage and Part D prescription drug plan changes. Medigap doesn’t have a fixed annual enrollment period — you can generally apply anytime, though medical underwriting may apply outside your original Medigap Open Enrollment window or a guaranteed-issue situation.
What is the Medicare Part B premium for 2026?
The standard Part B premium for 2026 is $202.90 per month, up from $185 per month in 2025. Higher-income enrollees pay more.
What happens if I miss the December 7 AEP deadline?
If you miss AEP and don’t qualify for a Special Enrollment Period, you’ll generally need to wait for the Medicare Advantage Open Enrollment Period (January 1 – March 31), which has more limited options — it only allows switching between Medicare Advantage plans or dropping Advantage for Original Medicare, not adding or changing a standalone Part D plan.
Looking for COBRA alternatives in Arizona? If you just lost job-based health coverage, your employer probably handed you a COBRA packet and a deadline. Before you sign it, it’s worth five minutes to see what else is actually available — because for most people, COBRA is the most expensive option on the table, not the only one.
Why COBRA Costs So Much
While you were employed, your employer was typically covering 60-80% of your premium. COBRA removes that subsidy entirely — you pay the full premium yourself, plus a 2% administrative fee. That’s why COBRA often runs $400-$700 a month for a single person, and considerably more for a family, for coverage that felt “free” or cheap while you had a job attached to it.
You have 60 days from the day your coverage ends to elect COBRA — and that same 60-day window opens up other options you may not know about.
Option 1: ACA Marketplace Plan (Usually the Strongest Option)
Losing job-based coverage triggers a Special Enrollment Period, letting you enroll in an ACA Marketplace plan right away instead of waiting for open enrollment. Marketplace plans cover the same essential health benefits as your old employer plan and can’t turn you down or charge you more for pre-existing conditions.
One important note for 2026: the enhanced premium tax credits that made Marketplace plans unusually cheap in recent years expired at the end of 2025 and were not extended. That doesn’t mean subsidies are gone — most people still qualify for some — but the numbers are different than they were a year or two ago. I’ve written a full breakdown of what changed in this post on the 2026 subsidy situation if you want the details.
Option 2: Short-Term Medical / Private PPO Plans
For healthy people bridging a gap of a few months, short-term medical plans are typically 40-60% cheaper than COBRA. The tradeoff is real, though: these plans are medically underwritten (your health history affects your rate and eligibility), they don’t have to cover the ACA’s essential health benefits, and they can deny claims tied to pre-existing conditions. Some states cap how long you can stay on one.
This is a reasonable option if you’re generally healthy and the gap is short and defined. It’s a riskier one if you have ongoing health needs — a single serious claim denial can cost far more than you saved on premium.
Option 3: A Spouse’s or Family Member’s Employer Plan
Losing your job is a qualifying life event that opens a special enrollment window on a spouse’s or parent’s employer plan, typically within 30-60 days. If that’s available to you, it’s often the cheapest and simplest option of all — worth checking before you assume COBRA or the Marketplace are your only paths.
Option 4: If You’re Near 65, COBRA May Not Be the Right Question
If you’re approaching Medicare eligibility, the calculation changes. Medicare’s Initial Enrollment Period is tied to your birthday, not your job loss, and missing it can trigger a permanent premium penalty. I’ve laid out the full timeline in this Turning 65 checklist — worth a look before you default to COBRA just because it’s the option in front of you.
Choosing Between COBRA Alternatives in Arizona
Run the real numbers before you choose anything:
Compare total cost, not just premium — factor in deductibles and how much of the year is left before they reset.
Check whether your doctors are in-network on the Marketplace or short-term plan you’re considering — COBRA keeps your old network, alternatives may not.
Weigh pre-existing conditions honestly. If you or a family member has ongoing care needs, ACA Marketplace coverage (or COBRA) protects you in a way short-term plans don’t.
Don’t let the 60-day window pass while you’re deciding — once it closes, your options narrow considerably.
Frequently Asked Questions
Why is COBRA so expensive?
While you were employed, your employer was typically covering 60-80% of your premium. COBRA removes that subsidy entirely — you pay the full premium yourself, plus a 2% administrative fee. That’s why COBRA often runs $400-$700 a month for a single person, and considerably more for a family.
How long do I have to elect COBRA coverage?
You have 60 days from the day your job-based coverage ends to elect COBRA. That same 60-day window also gives you time to compare other options, like an ACA Marketplace plan.
What’s usually the strongest alternative to COBRA?
An ACA Marketplace plan is usually the strongest option. Losing job-based coverage triggers a Special Enrollment Period, letting you enroll in a Marketplace plan right away instead of waiting for open enrollment — and Marketplace plans can’t turn you down or charge you more for pre-existing conditions.
Can I stay on a spouse’s or family member’s health plan instead of COBRA?
Losing your job is a qualifying life event that opens a special enrollment window on a spouse’s or parent’s employer plan, typically within 30-60 days. If that’s available to you, it’s often the cheapest and simplest option of all.
How I Can Help
This is exactly the kind of decision where a second opinion pays for itself. I’ll compare COBRA against ACA Marketplace and short-term options side by side, based on your actual doctors, budget, and health situation — not just the premium on the page. My help costs you nothing; you pay the same rate whether I’m involved or not.
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.
Frequently Asked Questions
Does Mayo Clinic Arizona accept Medicare?
Yes — Original Medicare plus a Medicare Supplement (Medigap) is accepted at Mayo Clinic Arizona with no exceptions.
Does Mayo Clinic Arizona accept Medicare Advantage plans?
Mayo Clinic does not accept non-contracted Medicare Advantage plans. If you’re on a Medicare Advantage plan, don’t assume you’re covered — check your specific plan’s contract status before you need care.
Does Mayo Clinic Arizona accept ACA Marketplace plans?
No. As of 2026, ACA Marketplace plans — including Ambetter, Blue Cross Blue Shield, Cigna, Oscar, and UnitedHealthcare Marketplace — are not accepted at Mayo Clinic Arizona.
What insurance do I need to see a doctor at Mayo Clinic Arizona if I’m under 65?
Private off-exchange PPO plans, such as UHC Choice Plus or Aetna Open Choice PPO, are accepted at Mayo Clinic Arizona. These are medically underwritten plans purchased outside the ACA Marketplace.
How I Can Help
Whether Mayo Clinic access is the deciding factor for you or just one piece of a bigger decision, I’ll compare your options — Medigap, ACA Marketplace, or private PPO — against what you actually need, including which hospitals and doctors matter to you. I don’t sell Medicare Advantage, and I’ll tell you plainly when a plan won’t get you where you want to go.

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.
If you or someone you love is on a Medicare Advantage plan, the ground just shifted under your feet — and most people don’t yet realize it.
A peer-reviewed research letter published in JAMA in February 2026, from a team at the Johns Hopkins Bloomberg School of Public Health, put a hard number on what many of us in this business have been watching unfold: roughly 2.9 million Medicare Advantage members — about 1 in 10 — are being forced out of their plans for 2026. Their insurance company either pulled out of the county entirely or shut down the plan they were on.
For context, the historical rate of forced disenrollment ran at about 1% from 2018 through 2024. It jumped to 6.9% in 2025, and now sits at 10% for 2026. That’s a tenfold increase in two years.
Why This Is Happening
The short version: several large insurers looked at rising medical costs and shifting federal payment rules, and decided they couldn’t make the Medicare Advantage math work in certain markets anymore. So they cut plans. Some smaller carriers exited entirely.
The people hit hardest, according to the research, were enrollees in PPO plans, plans from smaller carriers, plans with lower star ratings, and rural counties. If any of that describes your current plan, you should assume you’re closer to this problem than farther from it.
What Happens Next If You Get Forced Off Your Plan
Here’s the part almost no one talks about until it’s too late.
When your Medicare Advantage plan exits your county, you typically get a Special Enrollment Period to pick a new plan. That sounds like a solution. In many cases it isn’t.
Your options usually break down into three uncomfortable choices:
Enroll in a different Medicare Advantage plan — often one with a narrower network, a different provider list, and different drug coverage. Your current doctors may or may not be in-network. Your prescriptions may or may not be covered the same way.
Go back to Original Medicare — which covers about 80% of costs, leaving you exposed to the remaining 20% with no annual out-of-pocket cap. That’s why most people on Original Medicare add a Medicare Supplement (Medigap) plan to fill the gap.
Go back to Original Medicare and try to buy a Medigap plan — this is where the catch lives.
The Medigap Catch That Blindsides People
Federal law protects your right to buy any Medigap plan sold in your state, with no health questions asked, during a specific one-time six-month window that starts when you’re first 65 and enrolled in Medicare Part B.
If you missed that window because you went straight into Medicare Advantage, and you now need a Medigap plan because your Advantage plan disappeared, in most states the insurance company can look at your health history and either turn you down or raise your rate.
There are some situations that create guaranteed-issue rights — protected windows where you can buy Medigap without medical underwriting. Losing your Medicare Advantage plan because it exited your area is one of them. But the timing is tight (typically 63 days after your coverage ends) and the plans you’re guaranteed access to are a narrower set than you’d have during the original Open Enrollment Period.
This is why I’ve said for years, and will keep saying: the decision to enroll in Medicare Advantage isn’t fully reversible. It looks like a low-cost option going in. When the exit door slams shut, the underwriting door often does too.
What Medicare Beneficiaries Should Do Right Now
If you’re on a Medicare Advantage plan, here’s the checklist I’d walk any client through:
Read your Annual Notice of Change carefully. This letter comes every fall. It tells you whether your plan is continuing, changing, or exiting for the coming year.
Check whether your doctors and prescriptions are still covered. Even if your plan continues, the network and formulary can change year to year.
Know your guaranteed-issue rights. If your plan is exiting your area, you have a limited window to buy certain Medigap plans without health underwriting. Don’t miss it.
Talk to someone who doesn’t sell Medicare Advantage. I don’t. That’s a deliberate choice, not an oversight. If you’re getting advice only from someone who does, you’re getting one side of the picture.
Why I Don’t Sell Medicare Advantage
The Johns Hopkins study is the clearest third-party validation I’ve seen of the position I’ve held since day one of my practice. Medicare Advantage plans are heavily marketed, often with no monthly premium and extra perks that sound great. What the commercials don’t tell you is that the insurance company can leave the market and take your coverage with them — and once your health changes, getting back to Original Medicare with a supplement can be difficult or impossible.
I stick to Medicare Supplement plans, where you keep your own doctors, there’s no network to fight, and the coverage doesn’t disappear when a carrier decides a county isn’t profitable enough.
If You’re Reading This Because Your Plan Just Got Canceled
Don’t panic, but don’t wait either. Your guaranteed-issue window is real but limited. Call or text me at (623) 742-3878 (Arizona) or (910) 760-2124 (North & South Carolina) and let’s talk through what you actually qualify for right now. There’s no cost for the conversation, and I’ll tell you plainly whether a Medigap plan is a good fit for your situation — including when it isn’t.
