Medicare Advantage

Have You Read Your 2027 Medicare ANOC Yet, Irvine?

Orange County has 111 Medicare Advantage plans for 2027. Compared with 2026, 21 plans are not coming back, 28 are new, and 51 continuing plans changed in some way you should check before December 7, 19 of them under a new name. This guide covers what those numbers mean for Irvine, not which plan to pick.

IRVINE, Calif. — Fall 2026 is review season for Medicare, and for Irvine residents the window to make a change for 2027 coverage closes December 7, 2026. If you do nothing, your current plan simply rolls into next year with whatever changes its insurer has already mailed you — which is why a short, honest review now is worth the hour it takes.

This checklist walks you through what to read, what to check, and where to look it up.

What is the Medicare Annual Enrollment deadline for Irvine in 2027?

The deadline is December 7, 2026, and it applies the same way in Irvine as everywhere else in the country. The Annual Enrollment Period opened October 15, 2026, and anything you sign up for during that window starts January 1, 2027.

During this window you can switch between Original Medicare and a Medicare Advantage plan, change Advantage plans, or join, drop or switch a Part D drug plan. If you take no action, your current plan renews automatically — assuming the insurer still offers it in Orange County next year.

How do I read the Annual Notice of Change for my 2027 plan?

Your Annual Notice of Change, or ANOC, is the booklet your plan mailed (or emailed) by late September 2026, and it is the first thing to pull out of the stack. It compares your current 2026 plan to the same plan in 2027, side by side.

Read these pages carefully:

• Monthly premium for 2027 and any change to the Part B giveback, if your plan has one.
• Medical deductible, copays and coinsurance — primary care, specialists, urgent care, hospital stays, imaging.
• Maximum out-of-pocket for the year.
• Drug coverage: the deductible, the tiers, and whether any of your prescriptions moved tiers or dropped off the formulary.
• Extra benefits (dental, vision, hearing, over-the-counter, fitness, transportation) — these are the ones most likely to shrink quietly.

If anything in the ANOC surprises you, that is your signal to compare other options before December 7.

How do I check my Irvine doctors, hospitals and prescriptions for 2027?

Check each one against the 2027 version of the plan — not the 2026 one you have today. Networks and drug lists reset each January.

Three quick checks:

1. Doctors and specialists. Call your doctor's office directly and ask whether they will be in-network for your specific plan in 2027. If you use Hoag, UCI Health, Kaiser Permanente or MemorialCare facilities around Irvine, confirm the hospital system is still contracted with the plan — not just the doctor. 2. Prescriptions. Pull up the plan's 2027 formulary (the drug list) and search each medication by name and dose. Note the tier, any prior authorization, and whether your pharmacy is "preferred." 3. Pharmacies. A pharmacy that is "in-network" and one that is "preferred" can have very different cost-sharing. Confirm the status of the pharmacy you actually use.

The fastest way to compare across plans is the Medicare Plan Finder at medicare.gov, which lets you enter your drug list and ZIP code and see every plan available in Orange County.

How many Medicare Advantage plans and carriers can Irvine residents choose from?

Irvine is in Orange County, where 17 carriers offer 104 Medicare Advantage plans for the 2026 plan year, according to the CMS Medicare Advantage Landscape file. Of those, 75 are HMOs, 21 are HMO-POS plans, and 8 are PPOs; 40 are Special Needs Plans for people with specific conditions, dual Medicare-Medicaid eligibility, or who live in a facility, and 98 include drug coverage. CMS publishes the 2027 county-level counts when enrollment opens.

The 17 carriers serving Orange County are Aetna (CVS Health), Align Senior Care, Alignment Health Plan, Astiva Health, Blue Shield of California, CalOptima Health OneCare, Centene (WellCare), Central Health Medicare Plan, Champion Heath Plan, Clever Care Health Plan, Elevance Health (Anthem), Humana, Imperial Health Plan of California, Kaiser Permanente, Providence Medicare Advantage Plans, SCAN Health Plan, and UnitedHealthcare. The table below lists every plan by carrier.

What is changing in Medicare for 2027 that I should know about?

Two confirmed Part D numbers change on January 1, 2027:

• The Part D out-of-pocket cap rises from $2,100 in 2026 to $2,400 in 2027. Once you hit that amount in covered drug spending, your plan pays 100% of covered drugs for the rest of the year.
• The Part D maximum deductible rises from $615 in 2026 to $700 in 2027. Many plans set a lower deductible, but none can go above this.

The coverage gap (the old "donut hole") stays gone — Part D now has three phases, not four. And the Medicare Prescription Payment Plan is still available for 2027: it lets you spread drug costs over the calendar year in monthly bills instead of paying at the pharmacy counter.

The 2027 Part B standard premium and deductible, and the 2027 IRMAA income brackets, had not been published by CMS as of early fall 2026. CMS typically announces them in November — check medicare.gov for the official figures.

What should an Irvine checklist look like before December 7?

Here is the short version to work through at the kitchen table:

• Find your ANOC and your current plan's 2027 Summary of Benefits.
• List your doctors, your hospital system, your medications (name, dose, frequency), and your pharmacy.
• Open the Plan Finder at medicare.gov, enter your ZIP and your drug list, and compare 2027 plans side by side.
• Call each doctor's office to confirm 2027 network status.
• If you prefer to talk it through, call 1-800-MEDICARE (1-800-633-4227), available 24/7.
• Decide and enroll by December 7, 2026. Coverage starts January 1, 2027.

If you are happy with what your current plan looks like for 2027 after reading the ANOC, doing nothing is a perfectly valid choice.
