Medicare in Oxnard: 35 Advantage Plans to Compare for 2026

OXNARD, Calif. — If you're turning 65 soon or already on Medicare, here's the headline for your ZIP code: you have a lot of choices to weigh before the December 7 deadline.

Oxnard seniors have plenty to sort through this fall

Oxnard is in Ventura County, where 35 Medicare Advantage plans are available for 2026, according to the Centers for Medicare & Medicaid Services (CMS) plan landscape data. Ten carriers offer Medicare Advantage plans with prescription drug coverage (MA-PD) in the county. With nearly 146,000 residents age 65 and older locally, that's a big menu — and a lot of paperwork to sift through.

This guide won't tell you which plan to pick. Instead, it walks through how to think about your options and where to get trustworthy, unbiased help.

What "35 plans" actually means

The 35 figure counts Medicare Advantage plans available somewhere in Ventura County. Not every plan is offered in every ZIP code, and availability, networks, and drug lists can change each year. That's why comparing plans by county — not city — is the accurate way to think about it.

A few other numbers worth knowing about the local landscape:

• 10 carriers offer MA-PD plans in Ventura County.
• 0 stand-alone Part D drug plans are listed in the county's MA landscape file (stand-alone Part D plans are typically paired with Original Medicare; you can still shop these on Medicare.gov by ZIP code).
• 0 contracts in the local area currently carry a 4-star or higher overall rating from CMS. Star Ratings measure things like customer service and care quality, and they change every year.

Start with the basic Medicare structure

Before comparing plans, it helps to remember what the "parts" of Medicare do:

• Part A covers hospital stays.
• Part B covers doctor visits and outpatient care.
• Part C (Medicare Advantage) is a private plan that bundles Part A, Part B, and usually Part D drug coverage, sometimes with extras.
• Part D covers prescription drugs, either through a stand-alone plan or built into a Medicare Advantage plan.

You generally choose one path: Original Medicare (often paired with a stand-alone Part D plan and sometimes a Medigap supplement) or a Medicare Advantage plan. Both paths have trade-offs around networks, referrals, and out-of-pocket costs.

Key 2026 numbers to keep in mind

CMS has confirmed several program-wide figures for 2026 that apply no matter which plan you choose:

• $2,100 — the new annual out-of-pocket cap on Part D prescription drugs.
• $615 — the maximum Part D deductible a plan can charge.
• Coverage gap eliminated — as of 2025, the old "donut hole" is gone. Part D now has three phases: deductible, initial coverage, and catastrophic.
• Medicare Prescription Payment Plan — an optional program that lets you spread your drug costs across monthly payments instead of paying at the pharmacy counter.
• IRMAA — higher-income surcharges on Part B and Part D premiums start above $109,000 for a single filer in 2026.

How to narrow 35 plans down to a short list

You don't have to read every plan brochure. Try this order:

1. List your doctors and hospitals. Check which plans include them in-network. In Ventura County, that often means confirming your primary care provider and any specialists at systems like the local hospitals and clinics you already use. 2. List your prescriptions. Medicare.gov's Plan Finder lets you enter your drugs and see how each plan covers them. 3. Think about how you use care. Do you travel a lot? Prefer to see specialists without referrals? That points you toward certain plan types (HMO, PPO, etc.). 4. Check the Star Ratings as one input — not the whole decision. Ratings can help you spot plans with weaker customer service records. 5. Confirm the total picture, including premium, deductible, copays, and the annual out-of-pocket maximum.

Important dates for Oxnard readers
