Quick Answer

Phoenix has one of the most competitive Medicare Advantage markets in the country, with multiple carriers offering $0-premium HMO and PPO options for 2026. Most plans include Part D drug coverage, dental, and vision — but your out-of-pocket exposure can still reach up to $9,350 for in-network services (CMS, 2025), so the premium isn't the only number that matters.

How Medicare Advantage Works in Phoenix {#how-it-works}

Medicare Advantage (Part C) is an alternative to Original Medicare sold by private insurers and approved by CMS. When you enroll, the insurer delivers your Part A and Part B benefits — and most plans bundle Part D drug coverage, dental, vision, and hearing on top.

Phoenix sits in Maricopa County, one of the most plan-dense counties in Arizona. That competition tends to push premiums down and add-on benefits up, which is good for consumers. But more choices also mean more room to pick a plan that doesn't match your doctors, prescriptions, or budget.

Most Phoenix Advantage plans are either HMOs (you need referrals and must use a specific network) or PPOs (more flexibility, usually at higher cost-sharing). A small number of Private Fee-for-Service and Special Needs Plans (SNPs) are also available for those with specific chronic conditions or dual Medicare-Medicaid eligibility.

Want the full picture on how these plan types differ? Our Medicare Advantage guide walks through each one clearly.

Major Carriers Serving the Phoenix Area in 2026 {#major-carriers}

Several large carriers typically serve the Phoenix metro. For 2026, the market has historically included:

• UnitedHealthcare (AARP) — typically offers both HMO and PPO options with broad Arizona networks
• Humana — often competitive on prescription drug formularies and dental benefits
• Aetna — generally active in Maricopa County with HMO and PPO tiers
• Blue Cross Blue Shield of Arizona — a regional carrier with strong local provider relationships
• Cigna — may offer plans depending on county-level participation

Plan availability changes year to year. Always confirm a plan is available at your zip code and that your specific doctors and prescriptions are covered before enrolling. CMS's Medicare Plan Finder at medicare.gov is the authoritative source for confirmed plan availability in your area.

What Phoenix Plans Typically Cost {#what-plans-cost}

Here's what to understand about 2026 costs:

Part B premium: You pay $202.90/month regardless of plan type (CMS, November 2025). An Advantage plan with a $0 premium does not eliminate this cost.

Part B deductible: $283 for 2026 (CMS, November 2025). Some Advantage plans cover this; most do not.

In-network out-of-pocket maximum: CMS caps this at $9,350 for in-network services in 2026 (CMS, 2025). Individual plans may set lower maximums — that's a meaningful differentiator worth comparing.

Copays and coinsurance: These vary widely. A plan with a $0 premium might charge $50 per specialist visit and $400 per inpatient hospital day. A plan with a small monthly premium might have lower cost-sharing. Run your actual expected usage through the numbers.

Medicare Advantage vs. Medicare Supplement in Arizona {#advantage-vs-supplement}

This is the question I hear most. Neither option is universally better — they serve different needs.

Medicare Advantage tends to work well if you want one bundled plan, have a predictable set of providers in-network, and want extras like dental or gym benefits. The trade-off is network restrictions and variable cost-sharing if something serious happens.

Medicare Supplement (Medigap) works alongside Original Medicare and can cover most or all of the gaps — coinsurance, deductibles, and in some plans, foreign travel emergencies. It typically costs more per month but gives you much more predictable expenses and the freedom to see any Medicare-accepting provider nationwide.

In Arizona, Medigap plans are standardized by letter (Plan G is currently one of the most popular for new enrollees), but premiums vary by insurer and your age at enrollment.

Our Medicare Advantage vs. Supplement comparison and Medicare Supplement guide go deeper on the real-world differences.

Part D Drug Coverage and the 2026 Changes {#part-d-changes}

If you take regular prescriptions, 2026 brought a notable change worth understanding: the annual out-of-pocket threshold for covered Part D drugs is now $2,100 (CMS CY 2026 Part D benefit parameters). Once you hit that cap, you pay nothing for covered drugs for the rest of the year.

Covered insulin remains capped at $35/month under Part D — a fixed protection that applies whether you're on a standalone Part D plan or an Advantage plan with drug coverage built in.

When comparing Phoenix Advantage plans, check each plan's formulary carefully. A plan that covers your specific medications at Tier 1 or Tier 2 can mean a real difference in annual drug costs compared to one that puts them at Tier 3 or higher.

Our Part D drug coverage guide covers formularies, coverage phases, and how to check if your drugs are covered.

When You Can Enroll or Switch Plans {#enrollment-windows}

You generally can't switch Medicare Advantage plans outside specific windows:

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

Missing these windows can mean being stuck in a plan that doesn't fit for a full year. Our Medicare enrollment periods guide explains each window in plain terms.

How to Choose the Right Plan for You {#how-to-choose}

Start with these four questions:

1. Are my doctors in-network? Call the plan directly or use their provider directory — don't rely on outdated online lists. 2. Are my prescriptions on the formulary, and at what tier? This affects your actual drug costs more than the premium often does. 3. What is the plan's out-of-pocket maximum? Lower than $9,350 is better. Know your worst-case scenario. 4. Do I travel or spend time outside Arizona? HMOs may not cover out-of-area care except emergencies.

Frequently Asked Questions

Q: Can I keep my Arizona doctors if I switch to Medicare Advantage? A: It depends on the specific plan's network. Before enrolling, confirm your doctors participate in that plan's network directly — provider participation can change year to year, and online directories are not always current.

Q: Do Phoenix Medicare Advantage plans cover dental and vision? A: Many do include some dental and vision benefits, but coverage levels vary widely. Some plans offer routine cleanings and eye exams; others include allowances toward glasses or more extensive dental work. Always read the Evidence of Coverage to understand exactly what's included and what limits apply.

Q: What happens if I need care outside of Phoenix or Arizona? A: HMO plans typically only cover emergency and urgent care outside their service area. PPO plans generally offer out-of-network coverage, though at higher cost-sharing. If you travel frequently or split time between states, this is an important factor to weigh when choosing a plan type.

Q: Is Medicare Advantage or a Medigap plan better for someone in Phoenix? A: There's no single right answer — it depends on your health, budget, providers, and how often you travel. Advantage plans often have lower monthly premiums; Medigap plans often have more predictable out-of-pocket costs and broader provider access. A free Medicare review can help you compare both options based on your specific situation.

The Bottom Line

Phoenix offers a wide range of Medicare Advantage options for 2026, and the sheer number of plans can make choosing harder, not easier. The right plan isn't the one with the lowest premium — it's the one that fits your doctors, your prescriptions, and your financial situation.
