UnitedHealthcare's 2027 Medicare Advantage plans in Anaheim: one new, three renamed

ANAHEIM, Calif. — As the Annual Enrollment Period for 2027 Medicare coverage runs from October 15 to December 7, 2026, UnitedHealthcare's Medicare Advantage lineup in Orange County — the county Anaheim sits in — looks a little different on paper. For 2027, the carrier is offering 8 Medicare Advantage plans in the county: one is new, three carry renamed labels compared with 2026, and none of its current plans are being discontinued.

What UnitedHealthcare Medicare Advantage plans are offered in Anaheim for 2027?

In Orange County, which includes Anaheim, UnitedHealthcare is offering 8 Medicare Advantage plans for 2027. By type, that is 1 HMO and 7 HMO-POS plans. Two of the eight are Special Needs Plans — both Chronic Condition SNPs (C-SNPs) — and seven include Part D prescription drug coverage. One plan is offered without drug coverage.

What is new or renamed in UnitedHealthcare's 2027 Anaheim lineup?

For 2027, UnitedHealthcare has one new plan in Orange County — AARP Medicare Advantage from UHC CA-46 (HMO-POS) — and no plans leaving the county. Three plans carry new names compared with 2026, even though they are continuing offerings:

• AARP Medicare Advantage from UHC CA-33P (HMO-POS) — renamed (was AARP Medicare Advantage from UHC CA-43 (HMO-POS))
• AARP Medicare Advantage Giveback from UHC CA-31P (HMO-POS) — renamed (was AARP Medicare Advantage Giveback from UHC CA-20 (HMO-POS))
• AARP Medicare Advantage Patriot No Rx CA-MA1P (HMO-POS) — renamed (was AARP Medicare Advantage Patriot No Rx CA-MA01 (HMO-POS))

A rename does not necessarily mean the plan's benefits, premium or network are identical to last year. The Annual Notice of Change (ANOC) that UnitedHealthcare mails to current members in September spells out any differences for 2027.

How do the plan types and SNPs work?

UnitedHealthcare's Anaheim-area lineup for 2027 is split between HMO and HMO-POS plans. An HMO generally requires you to use the plan's in-network doctors and hospitals, except for emergencies. An HMO-POS (Point of Service) adds a limited ability to see some out-of-network providers, usually at higher cost.

Two of UnitedHealthcare's 2027 plans in the county — UHC Complete Care CA-19P (HMO-POS C-SNP) and UHC Complete Care Support CA-2AP (HMO C-SNP) — are Chronic Condition SNPs. C-SNPs are designed for people with specific qualifying conditions, and enrollment rules differ from standard Medicare Advantage. UnitedHealthcare does not offer Dual-Eligible SNPs (D-SNPs) or Institutional SNPs (I-SNPs) in the county for 2027.

Six of the 2027 plans include Part D drug coverage; one — AARP Medicare Advantage Patriot No Rx CA-MA1P (HMO-POS) — does not. "No Rx" plans are typically chosen by people who have other credible drug coverage, such as through the VA.

How do I check a UnitedHealthcare plan against my doctors and prescriptions before December 7?

Before December 7, 2026, the two most reliable tools are the Medicare Plan Finder at medicare.gov and 1-800-MEDICARE, which is open 24/7. Here is a short checklist:

1. Have your Medicare number, your current plan name, your prescriptions (with doses and quantities), and your preferred doctors and pharmacies ready. 2. On medicare.gov, enter your Anaheim ZIP code and compare 2027 plans side by side. You can filter by carrier to see UnitedHealthcare's plans only. 3. For each plan you are considering, check that your doctors are in-network for 2027 (not just 2026) and that each of your drugs is on the plan's 2027 formulary at a tier you can afford. 4. Read the Annual Notice of Change your current plan mailed in late September. It explains what is changing for 2027, including any rename. 5. If you want to confirm a provider is in-network, call the provider's office directly and ask about the specific 2027 plan by name.

If you take no action by December 7, 2026, your current plan — if it is still offered in 2027 — simply renews under its 2027 terms.

What else should Anaheim shoppers keep in mind for 2027?

UnitedHealthcare is one of 16 carriers offering Medicare Advantage in Orange County for 2027. All carriers together offer 111 plans in the county, so comparing across carriers — not just within one — is worth your time.

A few program-level figures to keep in mind:

• For 2027, the Part D out-of-pocket cap rises to $2,400 (up from $2,100 in 2026), and the Part D maximum deductible is $700 (up from $615 in 2026).
• The Part D coverage gap, or "donut hole," was eliminated as of 2025; Part D now has three phases.
• The Medicare Prescription Payment Plan lets you spread drug costs across the year in monthly payments; it is optional and you must opt in.
• The 2027 Part B standard premium and deductible, and the 2027 IRMAA income brackets, have not been announced yet. CMS typically publishes them later in the fall.
• The Medicare Advantage Open Enrollment Period runs January 1 – March 31, 2027. If you are in a Medicare Advantage plan after January 1, you have one more chance in that window to switch to another MA plan or return to Original Medicare.
