Medicare Insurance in Arizona

Find the best Medicare plan for Arizona residents

Arizona has more than 1.4 million Medicare beneficiaries — a number that continues to grow as the state remains one of the top retirement destinations in the country. With a warm climate, lower cost of living compared to many coastal states, and a large concentration of active senior communities, Arizona attracts retirees from across the nation. That also means a competitive Medicare marketplace, with dozens of insurers offering Medicare Advantage and Medicare Supplement plans throughout the state. Understanding your options before your Initial Enrollment Period closes — or during Annual Enrollment each fall — can save you thousands of dollars and ensure you have access to the doctors and hospitals you need.

10 Tips for Finding the Best Medicare Insurance in Arizona

  1. Learn the differences between Medicare Advantage and Medigap. Medicare Advantage (Part C) bundles your benefits through a private insurer, while Medigap (Medicare Supplement) works alongside Original Medicare to cover out-of-pocket costs. Each approach has different tradeoffs in cost, flexibility, and network access.
  2. Compare plans during Annual Enrollment (Oct. 15 – Dec. 7). This is the one time each year when you can switch, drop, or join a Medicare Advantage or Part D drug plan. Use the Medicare Plan Finder at medicare.gov to compare options side by side.
  3. Check whether your doctors are in-network. Medicare Advantage plans use HMO or PPO networks. Before enrolling, confirm that your primary care physician and any specialists you see regularly accept the plan you are considering.
  4. Review Part D drug formularies carefully. Prescription drug coverage varies widely between plans. Look up your specific medications on each plan's formulary to make sure they are covered at a tier you can afford.
  5. Understand the Star Ratings system. CMS rates Medicare Advantage and Part D plans on a 1–5 star scale for quality and performance. Plans rated 4 stars or higher generally signal better customer service and clinical outcomes.
  6. Ask about Extra Help for low-income beneficiaries. If your income and resources are limited, you may qualify for the federal Low Income Subsidy (LIS), also called Extra Help, which can dramatically reduce your Part D premiums and copays.
  7. Consider a Medigap policy during your Open Enrollment window. The six-month Medigap Open Enrollment Period begins the month you turn 65 and are enrolled in Part B. During this window, insurers cannot deny you coverage or charge higher premiums based on pre-existing conditions.
  8. Work with a licensed, independent Medicare agent. Independent agents represent multiple carriers and can compare plans across the market on your behalf — at no cost to you, since agents are compensated by the insurance companies.
  9. Factor in total annual costs, not just the monthly premium. A $0-premium Medicare Advantage plan may have higher copays, coinsurance, and a higher out-of-pocket maximum than a plan with a modest premium. Calculate worst-case annual costs for each option.
  10. Contact Arizona's SHIP program for free counseling. The Arizona State Health Insurance Assistance Program (SHIP), operated through the Arizona Department of Economic Security, offers free, unbiased Medicare counseling from trained volunteers statewide.

How Many Medicare Advantage Plans Are Available in Arizona?

Arizona is one of the most competitive Medicare Advantage markets in the country. For 2024, Arizona beneficiaries have access to more than 90 Medicare Advantage plans across the state, with the highest concentration of options in Maricopa County (Phoenix metro) and Pima County (Tucson). Major carriers offering Medicare Advantage plans in Arizona include UnitedHealthcare, Humana, Aetna, Blue Cross Blue Shield of Arizona, Cigna, Devoted Health, and several regional and local plans. The majority of Arizona Medicare Advantage enrollees are in plans that include prescription drug coverage (MA-PD plans). Average premiums for Medicare Advantage plans in Arizona remain well below the national average, and $0-premium options are widely available in most counties. Beneficiaries in rural counties such as Navajo, Apache, and Greenlee may have fewer plan choices, making it especially important to compare all available options in your specific county.

How Many Medicare Supplement Plans Are Offered in Arizona?

Arizona residents who prefer the flexibility of Original Medicare can choose from standardized Medigap plans sold by more than 30 licensed insurance carriers operating in the state. Because Medigap plans are federally standardized, a Plan G from one carrier offers identical core benefits to a Plan G from any other carrier — which means price and carrier financial strength are the primary differentiators when shopping. The most popular Medigap plan letters in Arizona are Plan G and Plan N, which together account for the majority of new enrollments among beneficiaries who aged into Medicare after January 1, 2020 (and are therefore no longer eligible for Plan F). Carriers with a strong presence in Arizona include Aetna, Mutual of Omaha, UnitedHealthcare (AARP), Blue Cross Blue Shield of Arizona, Cigna, Transamerica, and Medico. Because Medigap premiums for the same plan letter can vary by 40% or more between carriers in Arizona, comparing rates annually — or working with an independent broker — is strongly recommended.

Senior Population Facts (Over 65)

Arizona is home to approximately 1.3 million residents age 65 and older, representing roughly 17% of the state's total population — a share that has climbed steadily as Baby Boomers retire and relocate to the Sun Belt. The Phoenix–Mesa–Chandler metro area and the Tucson metro are the two largest concentrations of seniors in the state, though communities such as Sun City, Sun City West, Green Valley, and Prescott are nationally recognized retirement destinations. Key facts about Arizona's senior population include:

  • Healthcare: Arizona has seen significant growth in healthcare infrastructure to serve its senior population, including major hospital systems such as Banner Health, Dignity Health, and Valleywise Health. However, access to primary care and specialist physicians can be limited in rural and tribal areas of the state. Arizona consistently ranks among the states with the highest rates of Medicare Advantage enrollment, reflecting beneficiary preference for coordinated managed-care plans. The state also has a notable prevalence of heat-related illness and skin cancer among older adults, conditions tied directly to Arizona's desert climate.
  • Housing: Arizona's housing costs remain more affordable than coastal retirement markets, though the Phoenix metro has seen rapid appreciation in recent years. The state has a large inventory of age-restricted (55+) communities, particularly in the West Valley suburbs of Phoenix and in the Tucson foothills. Property tax exemptions and freezes are available to qualifying low-income seniors through the Arizona Senior Property Valuation Protection program, helping fixed-income retirees manage housing costs. Many seniors choose to downsize into active adult communities that offer amenities, social programming, and single-story floor plans suited to aging in place.
  • Economic Security: The median household income for Arizona seniors age 65 and older is approximately $45,000–$50,000 per year, with Social Security providing the primary income source for a significant portion of retirees. Arizona does not tax Social Security benefits at the state level, which provides meaningful relief for retirees on fixed incomes. However, Arizona does impose a state income tax on pension income and retirement account distributions, which retirees should factor into their financial planning. Poverty rates among Arizona seniors are slightly above the national average, and the state's Area Agencies on Aging administer programs to help low-income older adults access food assistance, transportation, and utility bill support.
