Kaiser Permanente's 2027 Medicare Advantage plans in Anaheim: three HMOs stay, one plan exits

Anaheim, Calif. — Fall 2026. As Medicare's Annual Enrollment Period runs October 15 through December 7, 2026, Kaiser Permanente's Medicare Advantage lineup for Orange County — the county Anaheim sits in — is set at three plans for the 2027 plan year, down from four this year. One plan from the carrier's 2026 roster is not coming back, no new plans are being added, and no plans are being renamed, according to the CMS Medicare Advantage Landscape Source File.

Here is what Anaheim-area readers who have (or are weighing) a Kaiser plan should know before December 7.

What Medicare Advantage plans does Kaiser Permanente offer in Anaheim for 2027?

Kaiser Permanente offers three Medicare Advantage plans in Orange County — the county Anaheim is part of — for the 2027 plan year. All three are HMOs, all three include Part D drug coverage, and one is a Dual Eligible Special Needs Plan (D-SNP) for people who qualify for both Medicare and Medi-Cal.

In alphabetical order, the 2027 plans are:

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

The table below lists every plan in the carrier's Orange County lineup. We're an independent consumer site — not Kaiser Permanente — and 15 other carriers also sell Medicare Advantage plans in the county, for a combined total of 111 plans in 2027.

What is new or not returning from Kaiser Permanente in Orange County for 2027?

For 2027, Kaiser Permanente has one plan not returning in Orange County and no new or renamed plans, according to CMS's year-over-year landscape data. The plan that is not on the 2027 list is Kaiser Permanente Dual Complete South P1 (HMO D-SNP), which appeared in the 2026 roster.

If a plan does not return, Medicare treats that as a qualifying event. You get a Special Enrollment Period to choose another Medicare Advantage plan or move back to Original Medicare with a stand-alone Part D plan. Your current plan should have sent (or will send) a non-renewal notice explaining your options and the dates that apply.

For the plans that are coming back, the small-print changes — copays, drug tiers, extra benefits, provider updates — are in your Annual Notice of Change (ANOC), which plans mail by late September each year.

What is a Special Needs Plan, and who qualifies in Anaheim?

A Special Needs Plan (SNP) is a type of Medicare Advantage plan built for people with specific situations. In Orange County, Kaiser Permanente's one SNP for 2027 is a D-SNP — a Dual Eligible Special Needs Plan for people who have both Medicare and full or partial Medi-Cal.

If you don't have Medi-Cal, you aren't eligible for a D-SNP; you'd look at the carrier's standard HMO offerings instead. If you think you might qualify for Medi-Cal (for example, due to income or being in a long-term care facility), the California Department of Health Care Services can confirm your status.

How do I check whether my doctors and prescriptions are covered before December 7, 2026?

The quickest way, from Anaheim or anywhere else in Orange County, is the Medicare Plan Finder at medicare.gov. You can enter your ZIP code, add your prescriptions and preferred pharmacy, and see which plans in your area cover them and at what tier.

A few steps that save headaches:

1. Pull out your current plan's ANOC. It shows what is changing on January 1, 2027 — premium, drug tier moves, extra benefits. 2. List your doctors and medications. Include dosage and how often you take each drug. 3. Check the plan's provider directory and formulary directly on the carrier's website, then confirm with the doctor's office. HMO plans require you to use in-network providers except for emergencies. 4. Call 1-800-MEDICARE (TTY 1-877-486-2048) if you want a Medicare representative to walk through options with you. The line is open 24/7.

What's changing across Medicare itself for 2027?

A few program-wide numbers are already confirmed for 2027 and apply no matter which plan or carrier you pick:

• The Part D out-of-pocket cap rises to $2,400 in 2027 (up from $2,100 in 2026). Once your out-of-pocket drug spending hits that cap, you pay $0 for covered Part D drugs the rest of the year.
• The Part D maximum deductible is $700 in 2027 (up from $615 in 2026). Individual plans can set a lower deductible.
• The Part D national base beneficiary premium is $41.33 for 2027. That's a formula input CMS uses — not what any specific plan charges.
• The coverage gap (the old "donut hole") remains eliminated; Part D now has three phases.
• The Medicare Prescription Payment Plan is still available: you can opt in to spread your drug costs across the calendar year in level monthly payments instead of paying at the pharmacy counter.

The 2027 Part B standard premium, Part B deductible, and the IRMAA income brackets had not been announced as of early fall 2026. CMS typically publishes those in November — watch medicare.gov for the official release rather than any projection.

What happens if I do nothing by December 7, 2026?

If your current Kaiser Permanente plan is on the 2027 list, it renews automatically on January 1, 2027 with the changes described in your ANOC. You don't have to re-enroll.

If your plan is the one not returning, you'll get a notice from the carrier and a Special Enrollment Period to switch — but it's smart to act during AEP so your new coverage starts cleanly on January 1. And if you enroll in a Medicare Advantage plan and change your mind, the Medicare Advantage Open Enrollment Period (January 1 – March 31, 2027) lets you switch to another MA plan or go back to Original Medicare once.
