Medicare Plans Available in Pima County, Arizona
Whether you live in Tucson, Marana, Sahuarita, Green Valley, Oro Valley, or anywhere else in Pima County — here's a clear picture of your Medicare plan options and what makes each one worth considering.
Pima County's Medicare Landscape
Pima County is home to nearly one million residents and has one of the highest concentrations of Medicare beneficiaries in Arizona. The county's large retirement communities — particularly in Green Valley, Marana, and Sahuarita — combined with the University of Arizona's health sciences presence make it one of the most medically rich counties in the Southwest.
That translates directly to Medicare beneficiaries: Pima County residents have access to a wider-than-average range of Medicare Advantage plans, multiple strong hospital systems, and specialist networks that cover virtually every medical specialty.
Your Three Core Medicare Paths in Pima County
Path 1: Original Medicare Only (Parts A & B)
All Pima County residents eligible for Medicare automatically have access to Original Medicare through the federal government. This covers hospital care (Part A) and outpatient/doctor care (Part B). You can see any Medicare-accepting provider in the country — including all of Tucson's major hospital systems.
The downside: Original Medicare alone leaves you exposed to significant cost-sharing with no annual cap. Most Pima County seniors add either a Medigap policy or Medicare Advantage to fill these gaps.
Path 2: Original Medicare + Medicare Supplement (Medigap)
Medigap policies are sold by private insurers but are federally standardized — meaning a Plan G from Humana covers the same things as a Plan G from UnitedHealthcare. In Pima County, most major national insurers offer Medigap, and competition keeps premiums relatively affordable compared to higher-cost markets like Phoenix or Scottsdale.
Plan G is currently the most popular Medigap plan for new enrollees in Pima County. After your $257 Part B deductible (2025), it covers virtually all Medicare-approved costs — giving you complete financial predictability and the freedom to see any Medicare-accepting doctor in the county or country.
You'll also need a separate Part D prescription drug plan alongside Medigap. Multiple Part D plans are available in Pima County zip codes — your specific medications should guide which plan you choose.
Path 3: Medicare Advantage (Part C)
Medicare Advantage plans are offered by private insurers approved by Medicare and replace your Original Medicare with an all-in-one plan. In Pima County, you'll typically find 20–30+ Medicare Advantage plans available depending on your zip code.
Major carriers active in Pima County include UnitedHealthcare, Humana, Aetna, Cigna, and Blue Cross Blue Shield of Arizona. Many offer $0 monthly premiums with dental, vision, hearing, and prescription drug coverage bundled in.
Pima County's Major Hospital Systems and Medicare
Understanding which hospital systems accept which Medicare plans matters — especially for Medicare Advantage enrollees who need in-network care:
- Banner — University Medical Center Tucson — Arizona's only Level 1 Trauma Center, home to the University of Arizona Health Network. Participates in select Medicare Advantage networks; verify before enrolling.
- Tucson Medical Center (TMC) — Major community hospital in central Tucson. Broad Medicare Advantage network participation.
- Carondelet Health Network (St. Mary's, St. Joseph's) — Catholic health system with multiple Tucson locations. Strong MA network participation.
- Northwest Medical Center / Common Spirit — Northwest Tucson/Marana coverage. Participates in major MA networks.
- Green Valley Hospital — Serves the Green Valley retirement community. Check MA network participation if you live in southern Pima County.
Important: Not all Medicare Advantage plans contract with all hospital systems. If you have a preferred hospital or specialist in Pima County, verify they're in-network before enrolling in any MA plan.
Special Needs Plans (SNPs) in Pima County
If you have a chronic condition like diabetes, heart failure, or COPD — or if you're dual-eligible for Medicare and Medicaid — you may qualify for a Special Needs Plan (SNP). SNPs are a type of Medicare Advantage plan specifically designed for people with complex health needs and often provide enhanced care coordination and lower cost-sharing for condition-specific care. Several SNPs are available in Pima County zip codes.
AHCCCS: Medicare + Medicaid in Pima County
Arizona's Medicaid program (AHCCCS) serves low-income seniors in Pima County who are "dual eligible" — qualifying for both Medicare and Medicaid. If you receive both, you may be eligible for a Dual Eligible Special Needs Plan (D-SNP) that coordinates your benefits and can dramatically reduce your out-of-pocket costs. Contact us or your local AHCCCS office to explore whether you qualify.
