Best Health Insurance in Arizona (2026)

We compared every 2026 Silver plan on Arizona's marketplace by premium, deductible and annual out-of-pocket limit for a 40-year-old. Oscar and Ambetter tied for the top score.

Oscar costs the least every month and remains the lower-cost option at every level of annual care use. But a year when you need care changes how the choice feels: Ambetter's $3,182 deductible is $219 lower, and that gap recovers the $135 monthly premium difference. Its four-star quality rating adds credibility Oscar does not carry.

Oscar is cheaper in every annual cost scenario by at least $1,332. The reason to choose Ambetter is not savings. It is the lower deductible that reduces cost exposure month to month and a four-star quality rating that Oscar does not carry. Those factors are worth $135 a month to the right buyer.

Arizona's marketplace changed more in 2026 than in prior years. Aetna exited entirely. Blue Cross Blue Shield stopped offering PPO plans. Seven carriers remain, all offering only HMO plans. 

Monthly Silver premiums range from $522 at Oscar to $781 at Blue Cross Blue Shield. That $259 monthly spread equals $3,108 per year. When buying a plan, the cheapest plan is not always the lowest-cost choice. How much you ultimately pay also depends on how often you use care and whether you reach your deductible.

Cigna leads this group with a 4.2 score. At $2,969, its Silver deductible is second-lowest in Arizona, $213 lower than Ambetter's and $40 above UHC's, for $17 less per month than UHC. If you expect to spend close to $3,000 on covered care and want the second-lowest Silver deductible in Arizona without UHC's premium, Cigna is worth running through the break-even calculation.

Blue Cross Blue Shield's $5,282 out-of-pocket maximum serves buyers with chronic conditions who expect to hit the annual limit. UHC's $2,929 deductible serves buyers who spent close to $3,000 on covered care last year and want a deductible that aligns with their history.

Some Arizona carriers also sell similar plans directly, outside the marketplace. Subsidies are not available for off-marketplace plans. For most buyers, HealthCare.gov is the path to reduce costs through premium tax credits.

Use the filters below to compare plans by your age, the metal tier that fits your budget and whether HSA eligibility matters. In 2026, all Bronze and Catastrophic plans on the marketplace are HSA-eligible, meaning you can pair them with a health savings account to pay medical costs with pre-tax money. Silver and Gold plans are not.

These figures are unsubsidized rates. If your income qualifies for advance premium tax credits through HealthCare.gov, what you pay each month will be lower. Check your eligibility at HealthCare.gov before treating any figure here as your final cost.

Arizona marketplace plans are all HMOs in 2026, removing the PPO-vs-HMO decision entirely. The only variables are premium, deductible and out-of-pocket maximum. Which matters most depends on how much care you use each year.

Health insurance premiums rise with age because carriers charge more for older buyers, as health care use increases with age. In Arizona's 2026 market, every plan is an HMO, and Platinum plans are unavailable. A 40-year-old pays $57 more per month on Silver than on Bronze. That gap buys a lower deductible and a lower annual spending cap.

Rates below are averages for HMO plans in Arizona at five age benchmarks. Your actual premium varies by county and the specific plan you choose.

At 60, a Silver plan in Arizona averages $1,401 a month compared to $1,138 for Expanded Bronze. That $263 monthly difference is $3,156 per year. If you expect regular care in your early 60s, Silver's lower deductible justifies the cost. For buyers who rarely need care, Expanded Bronze costs $263 less per month and keeps premiums lower all the way to Medicare eligibility at 65.

If you are 65 or older, or qualify for Medicare due to a disability, Medicare is entirely separate from the marketplace plans compared above. Arizona residents can access two primary types of additional coverage. Each has its own pricing structure, coverage rules and comparison framework.

Medicare Advantage plans, sometimes called Part C, replace original Medicare with a private plan that bundles all benefits. Medigap works differently: it sits alongside original Medicare and covers costs the base program leaves unpaid, including copays, deductibles and other cost-sharing.

If you have a coverage question or a complaint about a carrier, these agencies can help.

Arizona Department of Insurance and Financial Institutions (DIFI): Handles consumer complaints about insurance carriers operating in Arizona and provides guidance on coverage disputes and policy questions.

AHCCCS (Arizona Health Care Cost Containment System): Arizona's Medicaid program. If your income falls at or below 138% of the federal poverty level ($22,025 for a single adult in 2026), you likely qualify for low- or no-cost coverage that enrolls year-round. Apply at healthearizonaplus.gov.

HealthCare.gov: Compare marketplace plans, check subsidy eligibility and enroll in coverage. Open enrollment is from November 1 through January 15 each year.

Your annual care history is the most reliable input for this decision. If you went most of the year without a doctor visit, Oscar's $522 Silver plan will cost less in total than any other Arizona carrier. The $3,401 deductible only matters if you reach it.

If you saw a specialist, filled regular prescriptions or came within a few hundred dollars of your deductible, the math changes. Ambetter's $3,182 deductible is $219 below Oscar's, which means regular care users spend less on cost-sharing over a plan year. The four-star quality rating adds credibility to that value. For buyers with a chronic condition, Oscar's total worst-case annual cost of $12,181 is $2,473 lower than Blue Cross Blue Shield's $14,654. Consider BCBS only if your providers are in its network and not in Oscar's.

Before enrolling, confirm your doctors are in the carrier's network. For Ambetter and Antidote Health, also check county availability, both serve fewer than half of Arizona's 15 counties. Then compare your income through HealthCare.gov to see if tax credits reduce your actual premium. The enhanced tax credits that reduced costs for most Arizona buyers through 2025 expired at the end of that year. Your net monthly premium after tax credits may change which carrier costs you less.

Arizona residents often ask about enrollment periods, state insurance requirements and how multiple plans work together.

MoneyGeek reviewed every 2026 health insurance plan available in Arizona through the ACA marketplace, covering seven carriers across all available metal tiers (Catastrophic, Bronze, Expanded Bronze, Silver, Gold) for five age profiles (18, 26, 40, 50 and 60). Silver-tier plans at age 40 serve as the primary benchmark, because they represent the most common enrollment profile.

Our Scoring System

MoneyGeek's affordability score weighs three cost factors. Monthly premium carries the most weight at 60% because it's the recurring cost that most directly affects what you pay. Out-of-pocket maximum (20%) and deductible (20%) split the remaining weight equally. In all three cases, lower costs produce higher scores.
