How many Aetna Medicare Advantage plans are offered in Arizona for 2027?
Aetna is offering 8 Medicare Advantage plans in Arizona for the 2027 plan year, based on the CMS Landscape file. The mix is 5 HMO plans and 3 PPO plans. Seven of the 8 plans include Part D prescription drug coverage, and one is offered without drug coverage.
Among those 8, Aetna lists 2 Chronic Condition Special Needs Plans (C-SNPs), which are designed for people with specific qualifying chronic conditions. Aetna's 2027 Arizona list does not include any Dual Eligible Special Needs Plans (D-SNPs) or Institutional Special Needs Plans (I-SNPs). For context, 15 other carriers also offer Medicare Advantage in Arizona in 2027, and all carriers combined account for 148 plans statewide.
Which Aetna Medicare Advantage plans have the widest county reach in Arizona for 2027?
The Aetna 2027 plans with the broadest county footprint in Arizona are the three PPOs and one HMO that each appear in 3 Arizona counties: Aetna Medicare Eagle (PPO), Aetna Medicare Signature (HMO), Aetna Medicare Signature (PPO), and Aetna Medicare Value Care (PPO). The remaining four plans — two Aetna Medicare Chronic Care (HMO C-SNP) plans and two Aetna Medicare Prime (HMO) plans — are each listed in a single county.
Because Medicare Advantage is sold county by county, a plan that appears on the statewide list may not be offered in the county where you live. The full plan-by-plan breakdown with county reach is shown in the tables on this page; use those to check which Aetna plans actually appear on your county's menu.
What is new or not returning from Aetna in Arizona for 2027?
Aetna is introducing 4 new Medicare Advantage plans in Arizona for 2027 and is not returning 6 plans that were offered in 2026, according to the CMS year-over-year Landscape comparison. The new entries listed for 2027 include two Aetna Medicare Chronic Care (HMO C-SNP) plans and two Aetna Medicare Prime (HMO) plans.
If you are currently enrolled in an Aetna plan that is not continuing into 2027, you should receive an Annual Notice of Change or a non-renewal notice from the carrier explaining your options. That notice is the authoritative document for what is happening with your specific plan.
How do I check whether an Aetna plan is offered in my Arizona county and covers my doctors and prescriptions?
To confirm whether a specific Aetna plan is offered in your Arizona county for 2027, and whether it covers your doctors, hospitals and prescriptions, use the Medicare Plan Finder at medicare.gov, call 1-800-MEDICARE (1-800-633-4227, TTY 1-877-486-2048), or read the plan's own Evidence of Coverage and provider and pharmacy directories. These are the sources that carry the current, plan-specific details.
A few practical steps that apply to any plan on the Arizona list:
- Enter your ZIP code and county on Medicare.gov to see the exact plans available where you live.
- Enter your prescriptions, preferred pharmacy, and your doctors and hospitals to see how each plan handles them.
- Read the Evidence of Coverage for rules on referrals, prior authorization and out-of-network care.
This article does not quote premiums, deductibles, copays, benefits, networks or star ratings for any Aetna plan, because those details change by plan and county and should be confirmed directly on Medicare.gov or with the carrier.
What should Arizonans do before December 7, 2026?
Before December 7, 2026, Arizonans should review their 2027 coverage options during the Annual Enrollment Period, which runs October 15 – December 7, 2026. Any Medicare Advantage or Part D choice made in that window takes effect January 1, 2027.
A simple checklist:
- Read the Annual Notice of Change from your current plan, which arrives in the fall and spells out what is changing for 2027.
- Make a list of your doctors, hospitals, prescriptions and preferred pharmacies.
- Compare plans on Medicare.gov using your ZIP code so you see only plans available in your county.
- If you have questions, call 1-800-MEDICARE, available 24 hours a day, 7 days a week.
There is no need to rush a decision — the deadline is a fixed calendar date, not a sales deadline.
