Can You Switch to Medigap Later in Arizona?
Arizona has no Medigap birthday rule, so once your first six-month window closes, switching to or between Medicare Supplement plans usually means answering health questions. Here is when you are protected and when you are not.
Key takeaways
- Your Medigap Open Enrollment Period is six months, starting the month you are 65 or older and have Part B. During it, a company cannot turn you down or charge more for health reasons.
- Arizona has no birthday rule, according to the NAIC state chart dated May 11, 2026. After your window closes, insurers can usually ask health questions.
- Federal guaranteed issue rights still apply in specific situations, such as your Medicare Advantage plan leaving the area or a trial right within your first 12 months.
- Plan G pays everything Original Medicare leaves except the $283 Part B deductible (2026). Plan N adds some copays and does not pay Part B excess charges.
- Medigap plans are standardized: a Plan G from one company has the same benefits as a Plan G from another. Price and how the company raises rates are what differ.
In clients' words
What working with Viola looks like
I’m very happy I went to Viola at Rise up Benefits Group for my Medicare enrollment. I was inundated with mail and way too much information. I have been with Champ VA for 9 years so it gets confusing what to sign up for without losing those benefits as they become secondary. Viola explained everything and picked out the best option for me. I highly recommend her as it made this transition very smooth.

Usually not without answering health questions. In Arizona, once your six-month Medigap Open Enrollment Period ends, an insurance company can generally review your health before selling you a Medicare Supplement, and it can decline you or charge more. Arizona does not have a "birthday rule" that gives people a yearly chance to switch without underwriting.
That single rule shapes a lot of decisions. It is why moving from a Medicare Advantage plan back to Original Medicare during Annual Enrollment is easy on paper and sometimes hard in practice. It is also why the first Medigap decision you make at 65 matters more here than in states with yearly switching rights.
Below is how the windows work, the situations where federal law still protects you, and how Plan G and Plan N compare, so you can decide with clear eyes. We speak insurance, so you don't have to.
When can I buy Medigap without health questions in Arizona?
You can buy any Medigap plan sold in your area without health questions during your Medigap Open Enrollment Period: six months that start the first month you are both 65 or older and enrolled in Part B. During those six months, an insurer cannot refuse you, charge you more for your health, or make you wait for coverage of most pre-existing conditions.
The window starts automatically and cannot be paused or repeated. If you delay Part B because you are still covered by an employer plan, your window waits until Part B begins, which is one reason the timing of leaving work matters.
| Situation | Can the insurer ask health questions? |
|---|---|
| Medigap Open Enrollment Period (first 6 months of Part B at 65+) | No |
| A federal guaranteed issue right applies (see below) | No, for the plans the right covers |
| Switching plans on or near your birthday | Yes: Arizona has no birthday rule |
| Any other time | Usually yes |
Does Arizona have a Medigap birthday rule?
No. The NAIC chart of state Medigap rules, dated May 11, 2026, lists Arizona with no birthday rule. Several other states give people a window each year around their birthday to move to a plan with equal or lesser benefits without health questions; Arizona is not one of them.
The same chart lists Arizona without a state requirement that insurers sell Medigap to people under 65 who have Medicare because of a disability. If you are under 65 on Medicare, ask before you assume a Medigap plan is available to you.
When does federal law protect me after the window closes?
Federal guaranteed issue rights let you buy certain Medigap plans without health questions in specific situations, usually tied to losing other coverage. They apply in every state, including Arizona, and they come with deadlines.
- Your Medicare Advantage plan leaves your area or stops serving it, or you move out of its service area.
- The Medicare Advantage trial right. If you joined a Medicare Advantage plan when you first became eligible at 65 and want to leave within the first 12 months, or you dropped a Medigap plan to try Medicare Advantage for the first time and want to return within 12 months.
- Employer or union coverage that pays after Medicare ends.
- Your Medigap company goes bankrupt, or misled you or broke the rules.
Each right covers specific plan letters and has a time limit, often 63 days after the other coverage ends. Keep the letter that tells you your coverage is ending: it is your proof. Medicare.gov lists the full set of rights on its Medigap coverage pages.
How do Plan G and Plan N compare?
Plan G covers every gap in Original Medicare except the Part B deductible, which is $283 in 2026. Plan N covers the same hospital and most medical costs, but you pay small copays for some office and emergency room visits and it does not pay Part B excess charges.
| Benefit | Plan G | Plan N |
|---|---|---|
| Part A hospital coinsurance and costs up to 365 extra days | 100% | 100% |
| Part A deductible | 100% | 100% |
| Part B coinsurance or copayment | 100% | 100%, except up to $20 for some office visits and up to $50 for ER visits that do not lead to admission |
| Part B deductible | Not covered | Not covered |
| Part B excess charges | 100% | Not covered |
| Skilled nursing facility coinsurance | 100% | 100% |
| Hospice coinsurance and blood (first 3 pints) | 100% | 100% |
| Foreign travel emergency | 80%, after a $250 yearly deductible, $50,000 lifetime limit | 80%, after a $250 yearly deductible, $50,000 lifetime limit |
Excess charges are amounts some doctors who do not accept Medicare's approved amount as full payment can add, up to a limit. Whether they matter depends on whether your doctors accept assignment. We do not publish Medigap premiums here because they vary by company, age, ZIP code and pricing method; ask us for current quotes.
Both plans let you see any doctor in the country who accepts Medicare, which is why many snowbirds and frequent travelers choose Original Medicare with Medigap. Our post on travel coverage for snowbirds covers that in more depth.
What does a Medigap plan not cover?
A Medigap plan does not cover prescription drugs, routine dental, vision or hearing care, or long-term custodial care. It only pays its share of services Original Medicare covers, so most people pair it with a stand-alone Part D plan and decide separately how to handle dental and vision.
- Prescriptions: add a Part D plan when you first become eligible, or keep other creditable drug coverage, to avoid the Part D late penalty. Part D has a yearly out-of-pocket cap of $2,100 in 2026, and the CMS 2027 plan files list $2,400 for 2027.
- Dental, vision and hearing: these are separate policies or out-of-pocket costs with Original Medicare. Some people find this is the deciding factor between Medigap and Medicare Advantage.
- Long-term care: neither Medicare nor Medigap pays for ongoing help with daily activities. That is a separate planning conversation; Viola holds the CLTC (Certified in Long-Term Care) designation.
Seeing the whole picture side by side is usually what makes the choice clear. Our Medigap vs Advantage calculator lets you compare a year of costs both ways with your own numbers.
Should I switch from Medicare Advantage to Medigap this fall?
Only after you know whether an insurer will accept you. You can leave a Medicare Advantage plan for Original Medicare during Annual Enrollment, October 15 to December 7, 2026, but in Arizona the Medigap company can still review your health unless a guaranteed issue right applies.
- Check for a guaranteed issue right first. A non-renewal letter or a trial right changes everything.
- Apply for the Medigap plan before you leave your Medicare Advantage plan. Wait for approval.
- Then enroll in Original Medicare and a stand-alone Part D plan during Annual Enrollment, so you are never without drug coverage.
- Do not cancel anything until the new coverage is confirmed in writing.
The bottom line
In Arizona, the easiest time to buy a Medicare Supplement is your first six months on Part B after 65. After that, health questions usually apply unless a federal guaranteed issue right covers you. If you are weighing a move to Medigap this fall, get approved before you give anything up.

Six months, starting the first month you are 65 or older and enrolled in Part B. During it, insurers cannot decline you or charge more because of your health.
