UnitedHealthcare Medicare Advantage in Arizona for 2027: 21 Plans, County by County
PHOENIX — UnitedHealthcare will offer 21 Medicare Advantage plans across Arizona for the 2027 plan year, according to the Centers for Medicare & Medicaid Services Landscape Source Files. The lineup includes 14 HMO-POS plans and 7 PPO plans, and because Medicare Advantage is sold county by county, the plans listed statewide may or may not appear on a given county's menu. This explainer is published by an independent Medicare education site; we are not the government and not UnitedHealthcare.

What is UnitedHealthcare offering across Arizona for 2027?
UnitedHealthcare is offering 21 Medicare Advantage plans in Arizona for 2027, split between 14 HMO-POS plans and 7 PPO plans, per the CMS MA Landscape Source File. Of those 21, 18 include Part D drug coverage and 3 do not. Six are Special Needs Plans: 2 Dual Eligible SNPs (D-SNP), 3 Chronic Condition SNPs (C-SNP) and 1 Institutional SNP (I-SNP). SNPs have eligibility rules — qualifying for Medicaid, having a qualifying chronic condition, or living in a long-term care setting — so they are not open to every Medicare beneficiary. For context, 15 other carriers also offer Medicare Advantage in Arizona for 2027, and all carriers together list 148 plans statewide.
Which UnitedHealthcare plans reach the most Arizona counties in 2027?
The UnitedHealthcare plans with the widest county reach in Arizona for 2027 are two D-SNPs — UHC Dual Complete AZ-S001 and UHC Dual Complete AZ-YL — each offered in 15 counties, followed by AARP Medicare Advantage Patriot No Rx AZ-MA01 (PPO), offered in 13 counties. Two PPO plans with drug coverage, AARP Medicare Advantage from UHC AZ-0008 and AARP Medicare Advantage from UHC AZ-0010, are each offered in 12 counties. The UHC Complete Care Support AZ-1A (PPO C-SNP) is offered in 6 counties, and the UHC Nursing Home Plan AZ-F001 (PPO I-SNP) is offered in 3 counties. Many other plans — including several AARP Medicare Advantage HMO-POS plans — are listed in just one or two counties. The full county-by-county table appears on this page; use it to see which plans actually touch your county.
What is new or not returning from UnitedHealthcare in Arizona for 2027?
Two UnitedHealthcare plans are new for 2027 in Arizona and two plans from 2026 are not returning, based on the year-over-year comparison in the CMS Landscape files. The two new plans are AARP Medicare Advantage Patriot No Rx AZ-MA2 (HMO-POS) and AARP Medicare Advantage Patriot No Rx AZ-MA3 (HMO-POS), each listed in 1 county. One D-SNP has been renamed: UHC Dual Complete AZ-YL was previously UHC Dual Complete AZ-Y001. A rename is not the same as a non-renewal — the contract ID carries forward — but the plan name on your mailings and ID card may change. If your current plan is one of the two leaving the Arizona market, UnitedHealthcare is required to send a non-renewal notice, and you will have a Special Enrollment Period to pick a new plan.
How do I check whether a UnitedHealthcare plan is offered in my Arizona county and covers my doctors and prescriptions?
To confirm whether a specific UnitedHealthcare plan is offered in your Arizona county for 2027 and whether it covers your doctors and prescriptions, use the Medicare Plan Finder at medicare.gov or call 1-800-MEDICARE (TTY 1-877-486-2048), available 24/7. Enter your ZIP code and county, then your prescription list and pharmacies. Because Medicare Advantage is sold county by county, a plan listed in the statewide table above — for example an AARP Medicare Advantage PPO shown in 12 counties — may not be available where you live. For provider networks, check the plan's own online directory or call UnitedHealthcare using the number on the plan's page. For the full rules on cost sharing, prior authorization and extra benefits, the authoritative document is the plan's Evidence of Coverage. We do not publish premiums, copays, benefits or star ratings on this page.
What should Arizona Medicare beneficiaries do before December 7, 2026?
Before December 7, 2026, Arizona Medicare beneficiaries should review their current plan's Annual Notice of Change and compare their 2027 options on medicare.gov. The Annual Enrollment Period runs October 15 through December 7, 2026, and any choice you make — whether you stay, switch Medicare Advantage plans, move between Medicare Advantage and Original Medicare, or add or change a Part D drug plan — takes effect January 1, 2027. A short checklist: list your prescriptions and preferred pharmacies; list your doctors, specialists and hospitals; note any planned procedures; and then run those details through Plan Finder for each plan you are considering. If you qualify for a SNP — for example, you have both Medicare and Medicaid, a qualifying chronic condition, or live in a nursing facility — note that UnitedHealthcare's six SNPs in Arizona have their own eligibility rules you will need to meet.
Where can Arizonans get free help comparing 2027 Medicare plans?
Arizonans can get free, unbiased help comparing 2027 Medicare plans from Medicare itself: medicare.gov and 1-800-MEDICARE (TTY 1-877-486-2048), available 24 hours a day, seven days a week in English, Spanish and other languages via interpreters. The Plan Finder tool at medicare.gov lets you enter your ZIP code, prescriptions and pharmacies and see every plan available in your county side by side — not just UnitedHealthcare's — along with each plan's cost and coverage details that we are not permitted to summarize here. For questions about your Medicare eligibility, enrollment windows and premiums tied to your work history, contact the Social Security Administration.
