Best Health Insurance in Arizona (2026)

Oscar is the best health insurance company in Arizona, according to our analysis. Other top options include Ambetter, Cigna Healthcare, Blue Cross Blue Shield, and Antidote Health.

Arizona’s health insurance market consists exclusively of HMO plans. There are no EPO, POS, or PPO options available, which changes how you should evaluate insurers in the state. Because all plans operate within a managed network structure, network breadth is less of a differentiator than in states with multiple plan types. Instead, the most important factors to compare are premiums, deductibles and out-of-pocket maximums, which is exactly what our analysis prioritized.

Our analysis shows a clear split between low-premium and low-cost-sharing insurers in Arizona. Oscar and Antidote Health have the most affordable monthly rates, but both carry higher out-of-pocket maximums of $5,917 and $6,246, respectively. Blue Cross Blue Shield and Ambetter cost more per month but cap annual exposure more aggressively. For a healthy 40-year-old who expects minimal care, Oscar's $522 average premium saves $1,656 per year compared to Blue Cross Blue Shield's $781. For someone managing a chronic condition who may hit their out-of-pocket maximum, Blue Cross Blue Shield's $5,282 cap could save more than $600 in a high-utilization year compared to Antidote Health.

* Our picks represent the best health insurance options for Silver-tier plans.

With HMO as the only plan type available in the state, Arizona health insurance premiums vary primarily by age and metal tier. Oscar has Arizona's cheapest Silver HMO plans across all age groups we reviewed, costing $313 to $1,109 monthly depending on age.

By Age:   

• Children (0 to 14): Oscar HMO plans cost $313 monthly
• Teens (18): Oscar HMO plans cost $373 monthly
• Young adults (26): Oscar HMO plans cost $418 monthly
• Adults (40): Oscar HMO plans cost $522 monthly
• Seniors (60): Oscar HMO plans cost $1,109 monthly

Oscar’s premiums increase sharply with age. The insurer’s average Silver plan rate rises from $313 per month for a child to $1,109 for a 60-year-old, a 254% increase across the age range we analyzed. The steepest increase occurs between ages 40 and 60, when the average monthly premium jumps from $522 to $1,109, an increase of $587 per month over two decades.

For buyers approaching retirement age, this pricing trajectory is an important consideration. While Oscar is one of Arizona’s more affordable health insurance options, premiums rise in the years leading up to Medicare eligibility. Factoring those future costs into long-term healthcare and retirement planning can help avoid budget surprises later on.

Monthly premiums, deductibles and MOOP vary across Arizona insurers. Filter by age, metal level, plan type and HSA eligibility to compare costs.

Arizona's health insurance decision is simpler than in most states because HMO plans are the only plan type available in the state. When shopping for the best health insurance plans in the state, the choice comes down to cost structure and how much healthcare you expect to use:

Arizona's health insurance market consists solely of HMO plans, with no other plan type available in the state. Bronze HMO coverage costs $603 monthly, Silver averages $660, and Gold runs $787. Platinum HMO plans are unavailable in Arizona.

Health insurance costs in Arizona rise sharply with age. A 40-year-old pays an average of $660 per month for a Silver HMO plan, while a 60-year-old pays $1,401 for the same level of coverage. That's a 112% increase over 20 years. Bronze plans follow a similar pattern, increasing from an average of $603 per month at age 40 to $1,138 at age 60.

For older buyers, the tradeoff between Bronze and Silver coverage is more important. At 60 years old, Silver plans cost $263 more per month than Bronze plans ($1,401 versus $1,138). But Silver plans offer lower deductibles and lower out-of-pocket maximums, which can make the higher premium worthwhile if you expect to use healthcare services regularly. Healthcare needs increase with age for most people, which makes the Silver-versus-Bronze tradeoff more consequential as you get closer to Medicare eligibility.

Oscar is Arizona's best health insurance option for most buyers in 2026, with average Silver premiums of $522 per month, $138 below the state average. It's a strong choice for healthy adults focused on keeping monthly costs low.

Ambetter is a better fit for people who expect regular medical care. Its Gold plans have the state's lowest average deductible at $863, and its out-of-pocket maximums are below average, helping reduce costs for ongoing treatment and prescriptions.

Blue Cross Blue Shield has the strongest protection against a costly medical year, with Arizona's lowest average out-of-pocket maximum at $5,282.

Since all Arizona marketplace plans are HMOs, confirm your doctors are in-network and check your subsidy eligibility through HealthCare.gov before enrolling.

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.
