Medicare 2026 in Temecula & Murrieta: What’s Changing and How to Choose Your Plan
If you live in Temecula, Murrieta, Menifee, Sun City, Wildomar, Lake Elsinore, Hemet or Fallbrook, Medicare decisions are in season. The Annual Enrollment Period is open right now, 2026 costs went up compared with 2025, and the Part D drug benefit keeps changing. This guide covers the official 2026 numbers, what is changing for 2027, and how to compare your options. I’m Cesar Ramirez, a local licensed insurance agent (CA License #0M47591) with Temeku Insurance, and I help Southwest Riverside County and North San Diego County residents sort through these choices.
Medicare Annual Enrollment: October 15 – December 7
The Medicare Annual Enrollment Period (AEP) runs from October 15 through December 7 every year. During this window you can switch from Original Medicare to a Medicare Advantage plan (or back), change from one Medicare Advantage plan to another, and join, switch or drop a Part D prescription drug plan. Changes you make during this fall’s AEP take effect January 1, 2027 (Medicare.gov: Joining a plan).
If you’re already in a Medicare Advantage plan, there is also a Medicare Advantage Open Enrollment Period from January 1 to March 31, when you can switch to a different Medicare Advantage plan or go back to Original Medicare one time.
Plans can change their premiums, provider networks, drug lists (formularies) and copays every year. Review the Annual Notice of Change your plan mailed you in September. Then confirm that your doctors and prescriptions still fit before December 7.
2025 vs. 2026: The Official Medicare Numbers
CMS published the 2026 Part A and Part B amounts on November 14, 2025 (CMS fact sheet; also see the 2026 Medicare Costs booklet).
- Part B standard monthly premium: $202.90 in 2026, up from $185.00 in 2025.
- Part B annual deductible: $283 in 2026, up from $257 in 2025.
- Part A inpatient hospital deductible: $1,736 per benefit period in 2026, up from $1,676 in 2025.
- Part A hospital coinsurance: $434 per day for days 61–90 and $868 per lifetime reserve day in 2026.
- Skilled nursing facility coinsurance: $217 per day for days 21–100 in 2026.
- Part A premium: most people pay $0 because they or a spouse paid Medicare taxes long enough. People who must buy Part A pay up to $565 per month in 2026.
Higher-income beneficiaries pay an income-related monthly adjustment amount (IRMAA) on top of the Part B premium. In 2026 that brings the total Part B premium to between $284.10 and $689.90 per month, based on the income you reported to the IRS two years earlier. Social Security sends a letter telling you your exact amount.
The 2027 Part A and Part B amounts usually come out in the fall, and they had not been published when this article was written. Check CMS.gov for updates.
Part D: The Out-of-Pocket Cap on Prescription Drugs
Since 2025, Medicare Part D has had a yearly cap on what you pay out of pocket for covered drugs. For 2026 (CMS Part D redesign instructions):
- Maximum Part D deductible: $615. Some plans charge less or have no deductible.
- Initial coverage: after the deductible, you generally pay 25% coinsurance for covered drugs.
- Out-of-pocket cap: once your out-of-pocket spending on covered Part D drugs reaches $2,100, you pay $0 for covered Part D drugs for the rest of 2026.
For 2027, coverage you’ll choose during this AEP, Medicare.gov lists a maximum deductible of $700 and an out-of-pocket threshold of $2,400 (Medicare.gov: Drug coverage costs). Covered insulin is also limited to $35 for a one-month supply, and the Medicare Prescription Payment Plan lets you spread out-of-pocket drug costs into monthly payments instead of paying everything at the pharmacy.
Medicare Advantage vs. Medigap: Two Different Paths
Most people in Temecula and Murrieta end up choosing one of two routes:
Original Medicare + Medigap + Part D
Original Medicare (Parts A and B) lets you see any doctor or hospital in the country that accepts Medicare. A Medicare Supplement (Medigap) policy helps pay some of the costs Original Medicare doesn’t, like deductibles and coinsurance, and you add a separate Part D drug plan. You’ll usually pay higher monthly premiums but have more predictable costs and no network restrictions. This works well for people who travel or want to keep specific specialists.
Medicare Advantage (Part C)
Medicare Advantage plans are offered by private companies approved by Medicare. They cover everything Parts A and B cover, often include drug coverage, and may offer extra benefits like dental, vision or hearing. They use provider networks (HMO or PPO) and have a yearly out-of-pocket maximum for medical services. Which plans and medical groups are available depends on your county and ZIP code.
Neither path is right for everyone. The best fit depends on your doctors, prescriptions, budget, travel habits and health.
Why Your ZIP Code Matters in Riverside and San Diego Counties
Our area straddles two counties. Temecula, Murrieta, Menifee, Sun City, Wildomar, Lake Elsinore and Hemet are in Riverside County, and Fallbrook is in San Diego County. Medicare Advantage and Part D plans are approved by service area, so the plans, networks and costs available can differ between neighbors only a few miles apart. Local medical groups and hospital systems, including facilities in Murrieta, Wildomar, Temecula and Hemet, may be in network for one plan but not another. Always search your exact ZIP code in Medicare Plan Finder or review your options with a licensed local agent.
Help Paying Costs: Medicare Savings Programs and Extra Help
If your income and resources are limited, you may qualify for help:
- Medicare Savings Programs, run through California’s Medi-Cal program, can help pay Part B premiums and in some cases deductibles and coinsurance (Medicare.gov: Medicare Savings Programs).
- Extra Help (the Part D Low-Income Subsidy) lowers prescription drug premiums, deductibles and copays. You can apply through Social Security (SSA: Extra Help).
Income and asset limits are updated every year, so check the official pages or ask for help seeing if you qualify. Plenty of people who qualify never apply.
Turning 65 in Temecula or Murrieta?
Your Initial Enrollment Period usually lasts seven months: the three months before the month you turn 65, your birthday month, and the three months after (Medicare.gov). Signing up late for Part B or Part D without other qualifying coverage can mean lifelong late-enrollment penalties. If you’re still working and have employer coverage, the rules can be different, so check before you delay.
Your Medigap Open Enrollment Period is the six months starting the first month you’re both 65 or older and enrolled in Part B. During that time insurers generally can’t deny you a Medigap policy or charge more because of your health (Medicare.gov: Medigap).
