What Is Medicare?
Medicare is a federal health insurance program for people age 65 and older. It’s divided into parts that cover different types of care.
Part A
Hospital Coverage
Covers inpatient hospital stays, skilled nursing facilities, hospice, and some home health care.
Part B
Medical Coverage
Covers doctor visits, outpatient services, preventive care, and medical equipment.
Part C
Medicare Advantage
All-in-one plans from private insurers that include hospital, medical, and drug coverage as well as extra ancillary benefits.
Part D
Drug Coverage
Standalone prescription drug plans that help lower your medication costs.
Medicare Advantage vs Medicare Supplement
These are the two main paths beyond Original Medicare. Here’s how they compare at a glance.
| Feature | Medicare Advantage | Medicare Supplement |
|---|---|---|
| Monthly Premium | Often $0 | Higher premium |
| Doctor Networks | Usually required | Any Medicare-accepting doctor |
| Out-of-Pocket Limit | Yes, annual cap | Very minimal costs |
| Prescription Coverage | Usually included | Requires separate Part D |
| Extra Benefits | Dental, vision, hearing common | Not typically included |
When Should You Enroll in Medicare?
Most people first become eligible at 65. Your Initial Enrollment Period is a 7 month window and missing it can mean penalties.
3 Months Before
Start reviewing plans now. Enrolling early means coverage starts on time and you avoid delays.
Your Birthday Month
Coverage decisions are most commonly finalized during this month.
3 Months After
You still have time to enroll, but delaying could push your coverage start date later.
Not Sure When to Enroll?
Late enrollment penalties can follow you for life. Let me walk you through your specific situation and make sure you enroll at the right time.
Common Medicare Questions
Does Medicare cover everything?
No. Original Medicare doesn’t cover all costs many people add a Medicare Advantage or Supplement plan to help cover the gaps.
Can I keep my doctor?
It depends on the plan. Supplement plans let you see any Medicare accepting doctor nationwide. Advantage plans typically have provider networks that you must stay within.
Do Medicare Advantage plans cost money?
Some have $0 monthly premiums, but you still pay your Medicare Part B premium. You may also have copays when you use services.
Is it better to use a broker?
A broker compares plans from multiple companies at no cost to you, and helps you find coverage that fits your doctors, prescriptions, and budget.
The 7-Month Window in Detail
Your Initial Enrollment Period (IEP) is the single most important calendar of your 65th year. Miss it and you may go months without coverage and pay a late-enrollment penalty for the rest of your life.
Your IEP includes the 3 months before your 65th birthday month, your birthday month itself, and the 3 months after making seven months in total.
Example: turning 65 in September 2026
Your IEP runs June 1, 2026 through December 31, 2026. Enroll in the three months before your birthday and coverage starts the first of your birthday month (September 1). Enroll during or after your birthday month and coverage starts the first of the following month.
What happens if you miss it?
Two bad things. First, the next chance to enroll is the General Enrollment Period (January 1 – March 31), with coverage starting the month after enrollment that means a coverage gap of up to 15 months. Second, the Part B late enrollment penalty is permanent: 10% added to your monthly premium for every 12 months you were eligible but not enrolled. That penalty follows you for life.
Are you auto enrolled?
If you’ve been collecting Social Security for at least 4 months before turning 65, SSA will automatically enroll you in Part A but you usually have to opt into Part B. Your Medicare card arrives about 3 months before your birthday. If you’re not on Social Security yet, enrollment is not automatic. You must actively sign up at ssa.gov/medicare/sign-up or call Social Security at 1-800-772-1213.
The Real Numbers for 2026
The premium you pay depends on which parts you have, your income, and whether you add a Medigap or Advantage plan. Here are the actual 2026 figures most people need to know.
Part A — Hospital
Premium: $0 for most (if you or your spouse paid Medicare taxes 10+ years).
Inpatient deductible: $1,676 per benefit period.
Part B — Medical
Standard premium: $202.90/month.
Annual deductible: $283.
IRMAA (high earners): $284.10–$689.90/month depending on your MAGI from two years ago.
Medicare Advantage (Part C)
Arizona 2026 average premium: about $4.82/month.
Every Arizonan has access to at least one $0-premium Advantage plan. You still pay your Part B premium.
Medigap (Medicare Supplement)
Arizona age-65 range: about $44–$641/month depending on plan letter and carrier.
Doesn’t cover prescription drugs. You will need a separate Part D plan (typically $15–25/month for a base formulary).
Arizona-Specific Considerations
National Medicare articles skip the stuff that actually matters here. These are the four issues I walk every Arizona client through.
1. The East Valley provider landscape
If you live in Mesa, Gilbert, Chandler, Queen Creek, or Apache Junction, your provider network matters enormously. Banner Health, HonorHealth, Dignity Health, and Mayo Clinic Arizona all participate in Original Medicare — but their participation in specific Medicare Advantage plans changes every year. Before you sign any Advantage application, verify that each of your current doctors and your preferred hospital system are in-network for that specific plan in that specific year. This is the single most common mistake I fix for new clients.
2. Snowbirds and part-time Arizonans
If you spend summers in Minnesota, Montana, Michigan, or anywhere else, Original Medicare + Medigap is almost always the better path. Medicare Advantage plans are built around local networks, and while some offer “visitor” benefits, they’re inconsistent and generally cover only emergency care out of area. With Original Medicare, any doctor in the country who accepts Medicare will accept you.
3. AHCCCS and dual-eligibility
If your income and assets qualify you for AHCCCS (Arizona’s Medicaid), you may also qualify as a “dual-eligible” beneficiary. Dual-eligibles have access to Dual Eligible Special Needs Plans (D-SNPs) with $0 premiums, extensive extra benefits, and much lower out-of-pocket exposure. If you’re unsure whether you qualify, it’s worth ten minutes to check.
4. Under-65 Medicare (SSDI)
Arizona is one of the states where Medigap is not guaranteed-issue for Medicare beneficiaries under 65. If you’re on Medicare due to disability before 65, your Medigap options are limited and expensive. A Medicare Advantage plan is usually the realistic path until you hit 65, at which point you get a fresh Medigap Open Enrollment window regardless of your health.
Still Working Past 65? Read This First.
If you — or your spouse whose plan covers you — are still working with employer group health coverage, your Medicare timeline may look very different. Here are the three rules that matter.
If your employer has 20+ employees
Your employer plan is primary and Medicare is secondary. You can delay Part B enrollment penalty-free as long as you have continuous employer coverage. When the job (or coverage) ends, you get an 8-month Special Enrollment Period to sign up for Part B without penalty. COBRA does not count as creditable coverage for this purpose — don’t let COBRA trick you into missing your SEP.
If your employer has fewer than 20 employees
Medicare is typically primary. You should usually enroll in Part B at 65 even if you’re still working, because the small-group plan will only pay as secondary. Confirm with HR before you decide.
The HSA trap (this one costs people real money)
If you have a Health Savings Account through a high-deductible health plan, you must stop contributing to the HSA six months before you enroll in Medicare — or before you start Social Security, which auto-enrolls you in Part A. Medicare Part A enrollment is retroactive up to six months, so contributions during that retroactive window are subject to IRS tax penalties. This is one of the most common and expensive mistakes new Medicare enrollees make.
The 6-Month Countdown Checklist
Here’s exactly what to do, in what order, starting six months before your 65th birthday.
- 6 months out: Gather a list of your doctors, preferred hospital, and all prescription medications (names, dosages, frequency). Check your Social Security status at ssa.gov/myaccount.
- 4–5 months out: Schedule a free consultation with a local independent broker. Bring your list. We’ll map your options, compare Advantage vs. Medigap using your actual drugs and doctors, and flag any traps.
- 3 months out: Enroll in Medicare Parts A and B through Social Security (if you’re not auto-enrolled). This triggers your Medigap Open Enrollment window.
- 2 months out: Finalize your plan choice. Going Medigap? Apply during the 6-month Medigap Open Enrollment to lock in guaranteed-issue rights. Going Advantage? Submit the enrollment application.
- Birthday month: Coverage begins the first day of your birthday month (if enrolled in the 3 months prior). Plan ID cards arrive. You’re done.
- Every year after: Review your plan during the Annual Enrollment Period (Oct 15 – Dec 7). Plans and drug formularies change every year — last year’s best plan may not be this year’s.
Six Mistakes That Cost Arizonans Thousands
Missing the IEP because they assumed auto-enrollment
If you haven’t started Social Security yet, nobody is going to enroll you for you.
Choosing a Part D or Advantage plan on premium alone
The cheapest-premium plan is almost never the cheapest total-cost plan once drug tiers, copays, and the deductible get added up.
Not verifying provider networks
Plan directories update quarterly and often lag. Call your doctor’s office directly to confirm they accept the plan before you enroll.
Picking Advantage, then moving or traveling
Getting back into Medigap later requires medical underwriting and you can be declined for pre-existing conditions.
Contributing to an HSA after Medicare Part A starts
This triggers IRS tax penalties. Stop contributing 6 months before Medicare or Social Security enrollment.
Not shopping plans annually
Formularies, networks, and star ratings change every January. The plan that fit last year may not fit this year.
More Questions I Hear Every Week
Can I switch from Medicare Advantage back to Medigap later?
Yes, during the Annual Enrollment Period (Oct 15 – Dec 7) or the Medicare Advantage Open Enrollment Period (Jan 1 – Mar 31). But Medigap plans in Arizona can require medical underwriting after your initial Medigap Open Enrollment window closes, which means you can be denied or charged higher premiums based on your health. This is why the initial choice matters.
Do I need Part D if I don’t take any prescriptions?
Probably yes. If you go without creditable drug coverage when you’re first eligible and later decide you need it, you’ll pay a permanent late enrollment penalty of roughly 1% of the national base premium for every month you went without it. The cheapest Part D plans run around $15–25/month — usually worth it as insurance against future prescriptions.
What if I’m moving to Arizona from another state?
Moving out of your current Medicare Advantage or Part D plan’s service area triggers a Special Enrollment Period — you have up to 2 months after the move to pick a new Arizona plan without penalty. Medigap policies travel with you to any state where you see a Medicare-accepting provider, but you can swap to an Arizona-priced plan if you want to.
