Orange County's 2026 Medicare Advantage Menu: 104 Plans

For 2027, Anaheim is looking at 92 Medicare Advantage plans: 28 new, 21 gone since 2026, and 32 still here but changed in their terms, 19 of them under a new name. Below, how the lineup shifted in Orange County and what to compare, with no plan ranked or recommended.

For 2027, people with Medicare in Anaheim have a long list of Medicare Advantage plans to choose from. Anaheim sits inside Orange County, and Medicare Advantage availability is set at the county level. That means every plan offered anywhere in Orange County is on the menu for Anaheim residents too.

According to the CMS Medicare Advantage Landscape Source File for 2027, Orange County has 92 Medicare Advantage plans from 16 carriers. Every one of them includes prescription drug coverage. The full list is in the table below on this page.

What "available in Anaheim" really means

Medicare Advantage plans are approved by CMS to be sold in specific counties. Anaheim is in Orange County, so a plan offered anywhere in Orange County is available to an Anaheim resident who qualifies. The table below lists every Medicare Advantage plan CMS shows for Orange County in 2027, grouped by carrier in alphabetical order.

The list is availability only. It does not tell you what a plan costs, which doctors are in network, which drugs are on the formulary, or how it is rated. Those details live in the Medicare Plan Finder at medicare.gov and in each plan's Summary of Benefits and Evidence of Coverage.

The carriers offering plans in Orange County

Sixteen carriers offer Medicare Advantage in the county for 2027. In alphabetical order, they are Aetna (CVS Health), Align Senior Care, Alignment Health Plan, Astiva Health, Blue Shield of California, CalOptima Health OneCare, Centene (WellCare), Champion Health Plan, Clever Care Health Plan, Elevance Health (Anthem), Humana, Imperial Health Plan of California, Kaiser Permanente, SCAN Health Plan, UnitedHealthcare, and VillageHealth. Compared with 2026, Central Health Medicare Plan and Providence Medicare Advantage Plans are not offering plans in the county, and VillageHealth is new to the county.

Alignment Health Plan has the largest single-carrier count in the county with 17 plans, followed by Elevance Health (Anthem) at 12 and SCAN Health Plan at 10. Others, like Providence Medicare Advantage Plans and CalOptima Health OneCare, offer a single plan in the county.

How the plan types differ

The 104 plans fall into three types. Knowing what each type does helps you read the table:

• HMO (75 plans): You usually pick a primary care doctor and stay in the plan's network. Referrals are often needed for specialists.
• HMO-POS (21 plans): Like an HMO, but with a "point of service" option to see certain providers outside the network for some services.
• PPO (8 plans): You can see providers in or out of network, though out-of-network care usually costs more.

None of the 92 plans in Orange County is a stand-alone PPO without drug coverage; every plan in the county's 2027 lineup includes Part D drug coverage built in. CMS also lists 0 stand-alone Part D plans tied to this area's Medicare Advantage lineup — separate drug plans exist statewide, but they are not part of the MA lineup here.

Special Needs Plans in the mix

Of the 104 plans, 40 are Special Needs Plans (SNPs). SNPs are Medicare Advantage plans built for people who fit a specific group:

• D-SNP — for people who have both Medicare and Medicaid.
• C-SNP — for people with certain chronic conditions, like diabetes or heart disease.
• I-SNP — for people who live in a nursing home or need that level of care at home.

You have to qualify to enroll in one. The table marks each SNP with its type in parentheses so you can see at a glance which plans are general-market and which are for specific groups.

What to check before you enroll

Availability is just the first filter. Once you know a plan is offered in the county, look at:

• Whether your doctors and hospitals are in the plan's network.
• Whether your prescriptions are on the plan's formulary and at what tier.
• The plan's monthly premium (which is on top of your Part B premium), deductible, and copays.
• The plan's Star Rating, which CMS updates each year.

For 2027, some program-wide Part D rules apply no matter which plan you pick: the Part D out-of-pocket cap is $2,400, the maximum Part D deductible is $700, and the old "donut hole" coverage gap is gone (it was eliminated in 2025). If your drug costs are uneven month to month, the Medicare Prescription Payment Plan lets you spread them across the year.

Higher-income enrollees should also know that IRMAA surcharges on Part B and Part D start above $109,000 in income for a single filer in 2026.

Enrollment dates to circle

• Oct. 15 – Dec. 7: Medicare Annual Enrollment Period. You can join, switch, or drop a Medicare Advantage or Part D plan for coverage starting Jan. 1.
• Jan. 1 – March 31: Medicare Advantage Open Enrollment Period. If you're already in a Medicare Advantage plan, you can switch to another MA plan or go back to Original Medicare once during this window.

Special Enrollment Periods may apply if you move, lose other coverage, or qualify for Medicaid.
