Arizona ACA Marketplace & Subsidies
Arizona had a harder 2026 than most states. A carrier left the individual market and took about 55,000 people's plans with it, approved rate increases ran as high as 55%, and the 400% income cliff came back. If you were auto-enrolled into something you did not choose, it was matched on price — not on whether your doctor is in it.

An automatic replacement plan is matched on price, not on your doctors
When a carrier exits, enrollees are moved into a comparable plan from someone else. Nothing in that process checks whether your cardiologist is in the new network or whether your maintenance prescription sits on the new formulary — people find out at the pharmacy counter. If your plan changed carriers for 2026 and you have not verified both, that is the first thing to do, and a carrier exit gives you a Special Enrollment Period to act on what you find.
What Arizonans Should Check This Year
Which carrier you actually landed on
Rate increases ranged from about 2.5% to 55.3% by carrier. When the spread is that wide, last year's cheapest plan is very often not this year's — and auto-renewal will not move you.
Where your income sits against 400% FPL
The subsidy cliff is back. Below the line you may qualify for a substantial credit; a dollar above it, nothing. Near that line, an HSA contribution or a deductible business expense can be worth thousands.
AHCCCS if your income dropped
Arizona expanded Medicaid, so there is no coverage gap. Below 138% FPL, AHCCCS covers you with no premium and no enrollment window — you do not have to wait until November.
Arizona ACA FAQs
My Banner|Aetna plan was discontinued. What do I do?
Banner|Aetna exited Arizona's individual market entirely at the end of 2025, displacing roughly 55,000 enrollees. If you were one of them you were most likely auto-enrolled into a replacement plan from a different carrier — and an automatic match is chosen on price, not on whether your doctors are in the network or your prescriptions are covered. That is the single most important thing to check. A carrier exit also gives you grounds for a Special Enrollment Period, so you are not necessarily stuck with whatever you were moved into.
How does the ACA marketplace work in Arizona?
Arizona uses the federal marketplace at healthcare.gov. Open Enrollment runs November 1 through January 15; outside that window you need a qualifying life event — job loss, marriage, a new baby, a move, or your plan being discontinued — which opens a 60-day Special Enrollment Period. Seven insurers offered plans through the Arizona marketplace for 2026, down from the prior year after Banner|Aetna's exit. About 89% of Arizona enrollees receive a premium tax credit, averaging around $563/month in 2026.
Why did Arizona premiums increase so much for 2026?
Arizona saw some of the steepest approved increases in the country. Requested rate changes ranged from about 2.5% to 55.3% depending on carrier and plan, with Blue Cross Blue Shield of Arizona HMO plans up roughly 49% and UnitedHealthcare of Arizona around 44% before subsidies. On top of that, the enhanced premium tax credits expired at the end of 2025. Because the increases varied so widely between carriers, the plan that was cheapest for you last year is frequently not the cheapest one this year — this is a market where re-shopping genuinely pays.
What is the 400% FPL subsidy cliff and does it affect me?
For 2021 through 2025, enhanced credits capped what anyone paid at a percentage of income, with no hard income ceiling. That ended. For 2026 the original 400% of Federal Poverty Level cliff is back: below it you may qualify for a credit, and one dollar above it you qualify for nothing. For an older couple in Arizona this can be the difference between a manageable premium and a five-figure annual cost. If your income lands anywhere near that line, projecting it carefully — and understanding which deductions lower the figure that counts — is the highest-value hour you will spend on this.
What if my income is too low for a marketplace subsidy in Arizona?
Arizona expanded Medicaid, so there is no coverage gap here the way there is in Georgia or Alabama. AHCCCS — Arizona Health Care Cost Containment System — covers adults up to 138% of the Federal Poverty Level with no monthly premium and minimal out-of-pocket cost, and it has no open enrollment window. If your income drops mid-year, you can enroll in AHCCCS at that point rather than waiting for November.
