How many UnitedHealthcare Medicare Advantage plans are offered in Mesa for 2027?
UnitedHealthcare is offering 9 Medicare Advantage plans in Maricopa County — the county Mesa sits in — for the 2027 plan year, according to the CMS Medicare Advantage Landscape Source File. Eight are HMO-POS plans and one is a PPO. Eight include Part D prescription drug coverage; one does not.
That is one more plan than UnitedHealthcare offered in 2026. The company adds one new plan for 2027 and renames one existing plan; no 2026 plan is being discontinued.
The table below lists every UnitedHealthcare plan available in the county for 2027, with its plan type and whether it includes drug coverage.
What is new or renamed in UnitedHealthcare's 2027 Mesa lineup?
One UnitedHealthcare plan is new in Maricopa County for 2027: AARP Medicare Advantage Patriot No Rx AZ-MA2, an HMO-POS plan without drug coverage. It is the only plan in UnitedHealthcare's local 2027 roster that does not include Part D.
One plan has been renamed: UHC Dual Complete AZ-YL (HMO-POS D-SNP) was called UHC Dual Complete AZ-Y001 in 2026. The name is different; the Annual Notice of Change explains any benefit or network updates that come with it.
No UnitedHealthcare plan that was sold in Maricopa County in 2026 is leaving for 2027. If you are enrolled now, your plan will carry forward unless you choose something else.
Which UnitedHealthcare plans in Mesa are Special Needs Plans?
Four of UnitedHealthcare's nine 2027 plans in Maricopa County are Special Needs Plans (SNPs), which are designed for people in specific situations. The lineup includes two D-SNPs for people who have both Medicare and Medicaid (UHC Dual Complete AZ-S001 and UHC Dual Complete AZ-YL), one C-SNP for people with certain chronic conditions (UHC Complete Care AZ-1P), and one I-SNP for people living in a long-term care facility (UHC Nursing Home Plan AZ-F001).
SNPs have eligibility rules. You generally need proof of the qualifying condition, Medicaid status, or institutional stay to enroll, so check with the plan or 1-800-MEDICARE before you apply.
How do I check a UnitedHealthcare plan against my doctors and prescriptions before December 7?
Use the Medicare Plan Finder at medicare.gov. Enter your ZIP code, add the drugs you take with doses, and the tool will show each plan's drug costs at pharmacies near you. From each plan's page, you can open its provider directory and search for your doctors, hospitals and specialists by name.
Three quick checks are worth doing before December 7, 2026:
- Confirm every prescription you take is on the plan's 2027 formulary (drug list), and note the tier.
- Confirm your primary care doctor, any specialists you see, and your preferred hospital are in-network for 2027 — networks can change year to year.
- Read the Annual Notice of Change your current plan mailed you in late September; it spells out what is changing on January 1.
If something is unclear, call the plan directly using the number on your member ID card, or call 1-800-MEDICARE (TTY 1-877-486-2048), which is open 24 hours a day, seven days a week.
What Part D figures should Mesa shoppers know for 2027?
Two Part D numbers are confirmed for 2027. The annual out-of-pocket cap on covered prescription drugs rises to $2,400 (up from $2,100 in 2026). The maximum Part D deductible a plan can charge rises to $700 (up from $615 in 2026). The coverage gap (the old "donut hole") remains eliminated — Part D has three phases now.
The 2027 Part B standard premium and deductible, and the 2027 IRMAA income brackets, have not been announced yet. CMS typically publishes those figures later in the fall. The Medicare Prescription Payment Plan — the option to spread your out-of-pocket drug costs across the calendar year in monthly installments — continues in 2027 and is available with any Part D or Medicare Advantage plan that includes drugs.
What happens if I do nothing before December 7, 2026?
Nothing happens on December 8 to a person who does nothing. Your current plan renews on January 1, 2027, with the changes described in its Annual Notice of Change, as long as the plan is still offered in Maricopa County — and for UnitedHealthcare members here, every 2026 plan is still being offered in 2027 (one is under a new name).
If you want to switch to another UnitedHealthcare plan, change carriers, move between Medicare Advantage and Original Medicare, or add or drop drug coverage, you have until December 7, 2026. A separate window — the Medicare Advantage Open Enrollment Period, January 1 – March 31, 2027 — lets people already in a Medicare Advantage plan make one change.
