Medicare Advantage Plan Count in Temecula 2027

Riverside County has 68 Medicare Advantage plans for 2027. Compared with 2026, 17 plans are not coming back, 14 are new, and 32 continuing plans changed in some way you should check before December 7, 20 of them under a new name. This guide covers what those numbers mean for Temecula, not which plan to pick.

TEMECULA, Calif. — If you're turning 65 in Temecula or helping a parent sort through their Medicare mail, one of the first questions is usually the simplest: how many choices do I actually have around here?

Medicare Plan Availability Across the Temecula Area

The short answer is: quite a few. Medicare plan availability is set county by county, and Temecula sits inside Riverside County, one of the largest counties in California by population. That means the menu of options here looks a lot like what neighbors in Murrieta, Menifee, Hemet, Lake Elsinore, and other nearby communities see, too.

Here's a plain snapshot of what's on the table for 2027, plus what's changing compared with 2026.

What "Nearby Areas" Really Means

Medicare Advantage and Part D plans are offered by ZIP code, but the underlying availability is drawn at the county level. So a shopper in Temecula and a shopper 20 minutes north in Murrieta are generally looking at the same county-level menu, because both are in Riverside County.

That's helpful to know because:

• If you move within Riverside County, your plan options usually stay the same.
• If you move to San Diego County or Orange County, the menu changes — and that can trigger a Special Enrollment Period.
• Comparing "Temecula plans" versus "Murrieta plans" isn't really an apples-to-oranges exercise. It's the same county pool.

By the Numbers in Riverside County

Here's the current area-level picture for the county Temecula calls home:

• 68 Medicare Advantage plans are available in Riverside County for 2027, down from 91 in 2026.
• 17 carriers offer Medicare Advantage plans that include drug coverage (MA-PD).
• Roughly 382,888 residents aged 65 and older live in the county.
• Stand-alone Part D drug plans are sold statewide: California has 12 stand-alone Part D plans for 2026, sold statewide, with 10 available for 2027 — anyone in the area with Original Medicare can join one of them, and Medicare's Plan Finder has the current list.

These are counts only. They don't tell you which plan fits your doctors, your prescriptions, or your budget — that's the personal part of the decision.

What's Actually Changing for 2027

Even before you compare plans, it helps to know the ground rules being updated for 2027.

• Part D out-of-pocket cap: $2,100 in 2026 and $2,400 in 2027. Once your covered drug costs reach that year's cap, you pay nothing for covered drugs the rest of the year.
• Part D maximum deductible: up to $615 in 2026 and up to $700 in 2027. Plans can charge less, but not more.
• The old "donut hole" is gone. As of 2025, Part D has three phases instead of four.
• Medicare Prescription Payment Plan. This optional program lets you spread your yearly drug costs into monthly payments instead of paying big amounts at the pharmacy counter.
• IRMAA surcharges on Part B and Part D begin above $109,000 in income for a single filer in 2026.

These rules apply nationally — Temecula, Palm Springs, or Peoria — so they're a good starting point before you get into local plan differences.

Star Ratings, Briefly

You'll see Medicare "Star Ratings" (1 to 5) on plan cards. They're CMS's way of measuring things like customer service and how well a plan manages chronic conditions. Under CMS's 2026 Star Ratings, 9 of the 27 Medicare Advantage contracts offering plans in this area are rated 4 stars or higher, but ratings shift every year and are only one factor. They're a signal, not a scoreboard.

Key Dates to Circle

• Annual Enrollment Period: October 15 – December 7. This is when most people can join, switch, or drop a Medicare Advantage or Part D plan.
• Medicare Advantage Open Enrollment: January 1 – March 31. If you're already in a Medicare Advantage plan, this window gives you one chance to switch to another MA plan or return to Original Medicare.
• Special Enrollment Periods may apply if you move, lose other coverage, or qualify for Extra Help.
