For health insurance, Arizona uses the federal Marketplace at HealthCare.gov. Open Enrollment for 2027 coverage runs Nov 1, 2026 – Jan 15, 2027; enroll by Dec 15 for a Jan 1 start. Arizona expanded Medicaid, so adults under 138% of the poverty level usually qualify for AHCCCS instead.

Health insurance Arizona at a glance for 2027
Arizona has no state-run exchange. Individual and family plans are sold through HealthCare.gov, and low-income adults and children are covered by the state Medicaid agency, AHCCCS. The table below collects the official names and dates you need for the 2027 plan year in one place.
| Item | Arizona, 2027 plan year |
|---|---|
| Exchange | Federal Marketplace, HealthCare.gov |
| Open Enrollment | Nov 1, 2026 – Jan 15, 2027 (by Dec 15 for Jan 1 coverage) |
| Medicaid expansion | Yes, adopted (KFF tracker) |
| Medicaid program | AHCCCS (Arizona Health Care Cost Containment System); apply at Health-e-Arizona Plus |
| CHIP | KidsCare (run by AHCCCS) |
| State premium subsidy or reinsurance | None; Arizonans use the federal premium tax credit |
| Uninsured rate | 10.3% in 2024 vs. 8.2% nationally (Census ACS) |
| Insurance regulator | Arizona Department of Insurance and Financial Institutions (DIFI) |
| Federal Navigator | Arizona Association of Community Health Centers |
That uninsured figure comes from the Census Bureau’s state brief, Health Insurance Coverage by State: 2023 and 2024. It means roughly one in ten Arizonans had no coverage at all, a higher share than the country as a whole. If you are one of them, the rest of this guide shows where you fit. Shoppers watching costs closely should also read our affordable health insurance Arizona guide.
How health insurance in Arizona works
When people search for health insurance Arizona options, they usually mean one of two doors: the federal Marketplace or AHCCCS. Which door is yours depends mainly on household income and whether a job already offers you coverage.
Most Arizonans get coverage from a job, Medicare, AHCCCS or the Marketplace. If you have none of the first three, you buy your own plan on the health insurance Marketplace, either directly on HealthCare.gov or through a licensed agent or assistant connected to it. The price of the same plan is the same either way.
Every Marketplace plan covers the ACA’s essential health benefits: doctor visits, hospital stays, emergency care, prescriptions, maternity, mental health and preventive care. Insurers cannot turn you down or charge more because of a pre-existing condition. Plans come in Bronze, Silver, Gold and Platinum tiers, and the right tier depends on how much care you expect to use.
Arizona’s market is regional. A plan that is strong in Maricopa County may not be sold in Yuma or Flagstaff, and networks are often built around one hospital system. That is why your ZIP code, your doctors and your prescriptions should drive the comparison, not a brand name.
2027 Open Enrollment dates in Arizona
Arizona follows the HealthCare.gov calendar. Open Enrollment for 2027 coverage runs from November 1, 2026 through January 15, 2027. Enroll or switch by December 15, 2026 for coverage that starts January 1, 2027; enrollments from December 16 through January 15 start February 1.
A 2025 federal rule would have ended Open Enrollment on December 15 starting this season, but a federal court vacated that cutoff in 2026 and CMS confirmed the January 15 end date for this window. Treat December 15 as your practical deadline anyway, so there is no gap on New Year’s Day. Full details are in our Open Enrollment 2027 guide.
Outside that window you need a qualifying life event, such as losing job coverage, moving to Arizona, getting married or having a baby. That opens a Special Enrollment Period, generally for 60 days. AHCCCS and KidsCare accept applications all year.
AHCCCS, KidsCare and the 2027 Medicaid changes
AHCCCS is Arizona’s Medicaid program. Because Arizona expanded Medicaid, adults ages 19 to 64 with income up to about 138% of the federal poverty level can generally qualify, along with children, pregnant people, older adults and people with disabilities who meet program rules. You apply online through Health-e-Arizona Plus.
Children in families that earn too much for AHCCCS may qualify for KidsCare, Arizona’s Children’s Health Insurance Program. If your Marketplace application shows a child is likely eligible for AHCCCS or KidsCare, the child is generally not eligible for a premium tax credit.
What changes for AHCCCS members in 2027
The 2025 federal budget law (H.R. 1) brings several changes. According to the AHCCCS H.R. 1 overview, starting January 2027 many expansion adults must show 80 hours a month of work, job training, school or community service, or earn at least the federal minimum wage equivalent of those hours, and must renew coverage twice a year instead of once. American Indians, pregnant people and medically frail members are among those exempt.
AHCCCS also says that starting October 2026, some lawfully present immigrants, such as refugees and asylees, will qualify only for emergency services. Green card holders, certain Cuban and Haitian entrants and Compact of Free Association migrants remain eligible. Members can check their status at KeepMyAHCCCS.com.
Losing AHCCCS? If you lose AHCCCS eligibility, you can usually enroll in a Marketplace plan through a Special Enrollment Period. Act quickly, because the window is limited.

Premium tax credits for Arizonans in 2027
If your household income is between about 138% and 400% of the federal poverty level and you don’t qualify for AHCCCS or affordable job coverage, you can get a premium tax credit for a Marketplace plan in Arizona. The credit is set so you pay a fixed share of income for the benchmark Silver plan, from 2.15% at the low end to 10.22% at 300–400% FPL.
The enhanced credits that removed the upper income limit expired on December 31, 2025, and were not extended. That means the 400% FPL cliff applies to 2027 coverage: a household above it gets no credit. For a single adult, 400% FPL is $63,840; for a family of four, it is $132,000 (2026 HHS guidelines, which set 2027 subsidies).
Silver plans also carry cost-sharing reductions, which lower deductibles and copays, for incomes up to 250% FPL. Your credit is based on your estimated 2027 income and reconciled on the tax return you file in 2028, so update the Marketplace if your income changes. See the IRS premium tax credit basics and our 2027 subsidy guide.
The maximum out-of-pocket limit for a 2027 Marketplace plan is $12,000 for one person and $24,000 for a family. Nationally, insurers proposed a median 15% premium increase for 2027 according to KFF, and Arizona filings were among the higher ones, so comparing plans is worth the time.
Insurers selling 2027 plans in Arizona
Seven companies filed 2027 individual-market rates with Arizona regulators, according to the filings collected by ACA Signups: Blue Cross Blue Shield of Arizona, Arizona Complete Health (Health Net of Arizona) and Health Net Community Solutions of Arizona, Oscar, UnitedHealthcare, Imperial Insurance Companies and Antidote Health Plan of Arizona. Rates were still under DIFI review in October 2026.
UnitedHealthcare says it is expanding its Arizona service area for 2027 (UHC announcement). Cigna is leaving the individual market in every state where it sells, including Arizona, after December 31, 2026, so Cigna members must choose a new plan this fall.
When you compare health insurance, Arizona county lines matter. Not every insurer sells in every county. Networks and plan counts in rural Arizona can be much thinner than in Phoenix or Tucson. Check your exact ZIP code on HealthCare.gov or with Honesty before you decide.
American Indian and Alaska Native enrollees in Arizona
Arizona is home to many tribal nations, and members of federally recognized tribes get special Marketplace protections. They can enroll or change plans once a month all year, and, depending on income, can get plans with no out-of-pocket costs or no cost sharing for care from Indian Health Service, tribal or urban Indian programs.
American Indians are also exempt from the new AHCCCS work requirement. HealthCare.gov explains the rules on its American Indians and Alaska Natives page. If you get care through IHS, a Marketplace or AHCCCS plan can add access to specialists and hospitals outside the IHS system.
Phoenix, Tucson and the rest of Arizona
Where you live in Arizona shapes your options. The Phoenix metro has the most insurers and the biggest hospital networks, while rural counties may have only a few choices. We wrote dedicated local guides for the two cities Arizonans search most:
- Health insurance in Phoenix, AZ covers Maricopa County networks, Valleywise Health, community health centers and heat-season tips.
- Health insurance in Tucson, AZ covers Pima County, Banner – University Medical Center Tucson, El Rio Health and university and military households.
If you live in Flagstaff, Yuma, Prescott or a smaller town, the same rules apply. Just give extra attention to which local hospital each plan includes, because one network can be the difference between care nearby and a long drive.
Free help and consumer protection in Arizona
Free, unbiased help with health insurance Arizona applications is available statewide. The federally funded Navigator for 2026–2027 is the Arizona Association of Community Health Centers, working with partners such as El Rio Health and Asian Pacific Community in Action in seven counties including Maricopa and Pima (CMS Navigator awardees). Find an appointment at localhelp.healthcare.gov.
If you have a complaint about an insurer, a denied claim or a billing problem, contact the Arizona Department of Insurance and Financial Institutions, which regulates insurers and reviews health rate filings (DIFI health rates).
