UnitedHealthcare's 2027 Medicare Advantage plans in Oakland: a plan-by-plan look

Oakland, Calif. — October 2026. If you have a UnitedHealthcare Medicare Advantage plan in Oakland, or you are weighing one for next year, the carrier's 2027 lineup for Alameda County is set. UnitedHealthcare is offering two Medicare Advantage plans in the county for the plan year that starts January 1, 2027, and the window to compare and switch runs October 15 through December 7, 2026.

This article walks through what UnitedHealthcare is offering in the county, how the plans break down by type, and how to check any plan against your own doctors and prescriptions before the December 7 deadline. MyMedicarePlans.org is an independent news and education site; we are not UnitedHealthcare, and nine other carriers also offer Medicare Advantage plans in Alameda County for 2027.

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

Oakland is in Alameda County, where UnitedHealthcare is offering 2 Medicare Advantage plans for 2027. Both are HMO-POS plans, and both include Part D prescription drug coverage. One of the two is a Chronic Condition Special Needs Plan (C-SNP), which is designed for people with certain qualifying long-term health conditions.

The table below lists every UnitedHealthcare plan in the county by name and type. The two plans are the AARP Medicare Advantage from UHC CA-7 and the UHC Complete Care Support CA-8AP. For costs, copays, provider networks, drug lists and star ratings, use the Medicare Plan Finder at medicare.gov or call 1-800-MEDICARE — those are the authoritative sources, and they are personalized to your ZIP code.

What's new or not returning from UnitedHealthcare in Alameda County for 2027?

For 2027, UnitedHealthcare is not adding any new Medicare Advantage plans in Alameda County and is not discontinuing any. The two plans offered in 2026 are the two plans offered in 2027.

That does not mean nothing is changing. Every year, plans can adjust premiums, deductibles, copays, drug formularies, provider networks and extra benefits. Those changes are spelled out in the Annual Notice of Change (ANOC) that your plan is required to mail or email by late September. If you are enrolled now and do nothing, your plan renews January 1, 2027, with whatever changes its ANOC describes.

What is a Special Needs Plan, and who is the C-SNP for?

A Special Needs Plan is a type of Medicare Advantage plan limited to people who meet specific eligibility rules. UnitedHealthcare's 2027 Alameda County lineup includes one Chronic Condition SNP (C-SNP). C-SNPs enroll people with certain qualifying chronic conditions and tailor the benefits, provider network and drug list to that group.

You can only join a C-SNP if you have a qualifying condition that the specific plan covers. Medicare.gov and the plan's own materials spell out which conditions qualify.

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, type in the prescriptions you take (with dose and frequency), add your preferred pharmacy, and the tool will show each plan's estimated yearly drug costs, the formulary tier for each medicine, and whether your pharmacy is preferred. To check doctors and hospitals, open the plan's provider directory on the carrier's website or call the plan directly and ask whether a specific provider is in-network for the plan you are considering — not just for UnitedHealthcare generally, because networks can vary by plan.

Three things worth checking before December 7, 2026:

• Each prescription you take, by name and dose, on the plan's 2027 formulary.
• Your primary care doctor, any specialists you see, and your preferred hospital, in the plan's 2027 network.
• The plan's rules for referrals, prior authorization and out-of-network care (HMO-POS plans allow some out-of-network use, with different cost-sharing).

If you want a human to walk through it with you, 1-800-MEDICARE is open 24/7.

What should Oakland readers know about 2027 Medicare costs?

A few program-wide 2027 figures are already set by CMS. The Part D out-of-pocket cap rises to $2,400 in 2027 (up from $2,100 in 2026). The Part D maximum deductible a plan can charge is $700 in 2027 (up from $615 in 2026). The Part D national base beneficiary premium for 2027 is $41.33 — that is a formula input CMS uses, not a price any specific plan charges.

CMS has not yet published the 2027 Part B standard premium and deductible, or the 2027 IRMAA income brackets. Those usually come out in November. We will update when they do; in the meantime, do not rely on any projection you see quoted elsewhere.

When does the Annual Enrollment Period end, and what if I do nothing?

The Annual Enrollment Period runs October 15 through December 7, 2026. A change you make in that window takes effect January 1, 2027. If you do nothing, your current plan renews automatically for 2027 (if it is still offered), with any changes described in its ANOC.

If you enroll in a Medicare Advantage plan and change your mind, the Medicare Advantage Open Enrollment Period runs January 1 through March 31, 2027. During that window you can switch to a different Medicare Advantage plan once, or return to Original Medicare.
