Kaiser Permanente's 2027 Medicare Advantage lineup in Irvine: one plan is not returning

Irvine, Calif. — Fall 2026 is Medicare's annual shopping window, and Kaiser Permanente's 2027 Medicare Advantage lineup in Orange County, where Irvine sits, is set. The carrier is offering three Medicare Advantage plans here for 2027, down from four in 2026, with one plan not returning and no new or renamed plans added. Nothing changes automatically for someone who does nothing — current plans that are offered again next year will renew on January 1, 2027, with the changes spelled out in each member's Annual Notice of Change (ANOC).

This article is a local snapshot from MyMedicarePlans.org, an independent consumer news site. We are not Kaiser Permanente, and Kaiser Permanente is one of 16 carriers offering Medicare Advantage plans in Orange County for 2027.

How many Kaiser Permanente Medicare Advantage plans are offered in Irvine for 2027?

In Orange County, where Irvine is located, Kaiser Permanente is offering 3 Medicare Advantage plans for 2027. All 3 are HMOs, all 3 include prescription drug coverage, and 1 of the 3 is a Dual-Eligible Special Needs Plan (D-SNP) for people who have both Medicare and Medi-Cal. The carrier does not offer a Chronic Condition SNP (C-SNP) or Institutional SNP (I-SNP) in the county next year.

Plan availability is set at the county level by CMS, so the same lineup is available to eligible Medicare beneficiaries throughout Orange County, not just inside Irvine city limits.

Which Kaiser Permanente plans are available in Orange County for 2027?

The table below lists every Kaiser Permanente Medicare Advantage plan offered in the county for 2027. In alphabetical order, the three plans are:

• Kaiser Permanente Dual Complete South P10 (HMO D-SNP) — HMO D-SNP, with drug coverage
• Kaiser Permanente Senior Advantage LA, Orange Co. (HMO) — HMO, with drug coverage
• Kaiser Permanente Sr Advantage LA, Orange Value (HMO) — HMO, with drug coverage

We do not list premiums, deductibles, copays, benefits, provider networks or star ratings here — those are personal to each plan and change each year. You will find them on the Medicare Plan Finder at medicare.gov, in the plan's Evidence of Coverage, or by calling 1-800-MEDICARE.

What is new or not returning for 2027?

For 2027, Kaiser Permanente has 1 plan not returning in Orange County, and 0 new plans and 0 renamed plans. The 2026 lineup had 4 Kaiser Permanente plans; the 2027 lineup has 3.

If you are currently in a Kaiser Permanente plan that is not being offered again next year, Kaiser Permanente is required to mail you a notice this fall explaining what is happening and what your options are. If your plan is returning, your Annual Notice of Change describes exactly what is changing — premium, drugs on the formulary, cost-sharing and extra benefits — for the plan year that starts January 1, 2027.

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

Use three sources, in this order, before the December 7, 2026 deadline:

1. The Medicare Plan Finder at medicare.gov. Enter your ZIP code and your prescription drug list. The tool will show every Medicare Advantage plan available to you — not just Kaiser Permanente's — and estimate your yearly drug costs based on the plan's 2027 formulary. 2. The plan's own documents. Each plan publishes a Summary of Benefits, an Evidence of Coverage, a provider directory and a drug formulary for 2027. Confirm that the specific doctors, hospitals and pharmacies you use are listed, and that your medications are covered at a tier you can afford. 3. 1-800-MEDICARE. Available 24/7 for personal questions, including help comparing plans and understanding how a change would affect you.

A Medicare Advantage HMO generally requires you to use the plan's network and, in many cases, to get a referral to see a specialist. A D-SNP has eligibility rules tied to Medi-Cal status. Confirm you qualify before enrolling in a Special Needs Plan.

What 2027 Medicare figures are already confirmed?

CMS has published several Part D figures for 2027. The Part D out-of-pocket cap will be $2,400 in 2027, up from $2,100 in 2026. The Part D maximum deductible will be $700 in 2027, up from $615 in 2026. The Part D national base beneficiary premium for 2027 is $41.33 (a formula input used behind the scenes, not what any specific plan charges).

The 2027 Part B standard premium and deductible, and the 2027 IRMAA income brackets, have not been announced yet. CMS normally publishes those figures later in the fall, usually in November. We will update our coverage when they are released.

The coverage gap (the old "donut hole") was eliminated starting in 2025, so Part D now has three phases. The Medicare Prescription Payment Plan is also available for anyone who wants to spread drug costs across the year in monthly installments.

What are the key Medicare dates this fall?

The Annual Enrollment Period runs October 15 through December 7, 2026. A change you make during that window takes effect January 1, 2027. If you take no action and your current plan is offered again next year, it will renew with the changes described in your ANOC.

After AEP, the Medicare Advantage Open Enrollment Period runs January 1 – March 31, 2027. During those three months, if you are already in a Medicare Advantage plan, you can make one change — switch to another Medicare Advantage plan or go back to Original Medicare (and add a Part D plan).
