Quick Answer

Phoenix-area residents on Medicare have dozens of Medicare Advantage plans to choose from in 2026, offered by carriers like UnitedHealthcare, Humana, Aetna, and Blue Cross Blue Shield of Arizona. These plans bundle your hospital, medical, and often drug coverage into one plan — sometimes with a $0 monthly premium — but they come with trade-offs around provider networks and out-of-pocket costs worth understanding before you enroll.

How Medicare Advantage Works in 2026 {#how-medicare-advantage-works}

Medicare Advantage (Part C) is an alternative to Original Medicare. Instead of Medicare paying your claims directly, you enroll in a private insurance plan that has been approved by CMS to provide at least the same benefits as Parts A and B.

Most plans in Phoenix also bundle Part D prescription drug coverage, and many include extras like dental, vision, hearing, and fitness benefits. You still pay your Part B premium — $185/month in 2026, per CMS — on top of whatever your plan charges (which may be $0 or higher).

The catch: you're working within a network. Most Medicare Advantage plans in Phoenix are HMOs or PPOs, which means your costs can be significantly higher if you see out-of-network providers, or in some HMO cases, those visits won't be covered at all.

What's Available in Phoenix for 2026 {#whats-available-in-phoenix}

Phoenix and the broader Maricopa County area typically see strong plan competition. For 2026, carriers commonly offering plans in the Phoenix market include:

• UnitedHealthcare (AARP MedicareComplete) — offers both HMO and PPO options; PPO plans give broader provider flexibility.
• Humana — known for strong Part D integration and dental add-ons; offers HMO and PPO tiers.
• Aetna — competitive $0-premium HMO options with fitness benefits.
• Blue Cross Blue Shield of Arizona — strong local provider relationships across the Valley.
• Wellcare and Cigna — additional options worth comparing depending on your ZIP code.

Plan availability varies by ZIP code, so what's offered in Scottsdale may differ from what's available in Glendale or South Phoenix. Use our plan comparison tool to see exactly what's in your area.

2026 Costs You Should Know Before You Compare {#2026-costs-you-should-know}

Before you lock in on a plan, get clear on what costs actually look like in 2026:

• Part B premium: $185/month (CMS, November 2025) — you pay this regardless of which plan you choose.
• Part B deductible: $257/year (CMS, November 2025).
• Medicare Advantage out-of-pocket maximum: CMS caps this at $9,350/year for in-network services in 2026. Plans may set their own limit below that ceiling.
• Part D drug costs: Capped at $2,000/year out of pocket starting 2025, under the Inflation Reduction Act.
• Insulin: Covered insulin is capped at $35/month under Medicare Part D.

These cost caps matter. A $0-premium plan with high copays could end up costing more than a plan with a modest premium if you use medical care regularly. See our 2026 Medicare costs page for a side-by-side breakdown.

Arizona-Specific Considerations for Phoenix Residents {#arizona-specific-considerations}

Arizona has some features that can affect how your Medicare Advantage plan actually performs day to day.

Provider networks in the Valley: Phoenix has a large and spread-out metro area. Network size matters here more than in a compact city. Before enrolling, verify that your specific doctors — not just the hospital system — are in-network. Carriers sometimes contract with a hospital but not with every physician who practices there.

Snowbird and travel considerations: If you split time between Arizona and another state (or travel frequently), a standard HMO plan may leave you with limited coverage outside the Phoenix area. PPO plans typically offer more flexibility, though out-of-network costs are higher. Some carriers offer special plans designed for people who live in two states — ask specifically about this if it applies to you. For Arizona Medicare data and trends, you can also review Florida Medicare data as a comparison market.

AHCCCS and dual-eligible plans: Arizona residents who qualify for both Medicare and Medicaid (AHCCCS) may be eligible for Dual Special Needs Plans (D-SNPs), which can coordinate benefits across both programs and may offer additional support. This is worth exploring separately with a licensed advisor.

Medicare Advantage vs. Medigap: The Honest Trade-Off {#medicare-advantage-vs-medigap}

This is probably the most important decision you'll make in Medicare, so I want to be straight with you.

Medicare Advantage tends to have lower or $0 monthly premiums, built-in drug coverage, and added benefits. But you're trading that lower upfront cost for network restrictions, prior authorization requirements for some services, and variable copays each time you use care.

Medigap (Medicare Supplement) plans charge a monthly premium on top of Part B, but they fill in most of Original Medicare's cost-sharing gaps. With a Plan G, for example, you typically pay very little out of pocket once you hit your Part B deductible. You can see almost any doctor who accepts Medicare — no network restrictions.

Neither option is universally better. It depends on your health, your budget, and how much you value provider flexibility. Read our full breakdown at Medicare Advantage vs. Supplement before deciding.

When to Enroll or Switch Plans {#when-to-enroll-or-switch}

Timing matters. You generally have these windows:

• Initial Enrollment Period (IEP): 7-month window around your 65th birthday.
• Annual Enrollment Period (AEP): October 15 - December 7 each year. Changes take effect January 1.
• Medicare Advantage Open Enrollment: January 1 - March 31. You can switch MA plans or return to Original Medicare once.
• Special Enrollment Periods (SEPs): Triggered by qualifying life events like losing employer coverage.

Missing your IEP can result in late enrollment penalties that stay with you permanently. See our Medicare enrollment periods guide for details.

How to Compare Plans Without Losing Your Mind {#how-to-compare-plans}

Here's a practical checklist for Phoenix residents comparing plans this year:

1. List your doctors — confirm each is in-network for any plan you're considering. 2. List your prescriptions — run them through the plan's formulary to check tier and cost. 3. Look at total annual costs — premium × 12, plus typical copays for how often you actually use care. 4. Check prior authorization rules — especially if you have ongoing specialist care or take specialty medications. 5. Compare dental and vision specifics — these benefits vary widely; some plans offer meaningful coverage, others offer very little. 6. Don't default to last year's plan — benefits, networks, and drug formularies change every year.

Our Part D drug coverage guide and plan comparison tool can help you work through steps 2 and 3.

Frequently Asked Questions

Q: Can I keep my current Phoenix-area doctor if I switch to Medicare Advantage? A: It depends on the specific plan's network. Before enrolling, call your doctor's office directly and ask if they accept the plan — not just the carrier name, but the specific plan name and ID. Provider directories are sometimes outdated.

Q: Are there Medicare Advantage plans in Phoenix with $0 premiums in 2026? A: Yes, several carriers typically offer $0-premium plans in the Phoenix market. Keep in mind you still pay the $185/month Part B premium, and $0-premium plans may have higher copays or more limited networks than plans with monthly premiums.

Q: What happens if I need care outside of Phoenix — say, I'm traveling? A: Most HMO plans cover emergency and urgent care nationwide, but routine care is generally limited to your network area. PPO plans offer more flexibility for out-of-area care, though at higher out-of-pocket costs. If you travel or split time between states, ask specifically about multi-state plan options.

Q: Is a Medicare plan review Arizona service free to use? A: Working with a licensed Medicare advisor is typically free to you. Advisors like me are compensated by insurance carriers when you enroll, which means the cost doesn't come out of your pocket. A free Medicare review gives you personalized guidance without any obligation to enroll.

The Bottom Line

Phoenix offers a strong Medicare Advantage market in 2026, with real competition among carriers — which is generally good for you as a consumer. But more choices also means more room to pick the wrong plan if you're not comparing carefully. The right plan depends on your doctors, your medications, your health history, and how you use care. If you're ready to compare your options with someone who will give you straight answers, schedule a free Medicare review and we'll work through it together.
