MyMedicarePlans.org is an independent consumer news and education site. We are not Blue Shield of California, and Blue Shield is one of 16 carriers offering Medicare Advantage plans in Orange County for 2027.
What Blue Shield of California Medicare Advantage plans are offered in Santa Ana for 2027?
Santa Ana is in Orange County, where Blue Shield of California will offer five Medicare Advantage plans for 2027. All five are HMOs, and all five include Part D prescription drug coverage. None of them are Special Needs Plans (no D-SNP, C-SNP or I-SNP from this carrier in the county).
The table below lists every Blue Shield of California plan available in the county next year. In alphabetical order, those plans are:
- Blue Shield 65 Plus (HMO)
- Blue Shield 65 Plus Plan 2 (HMO)
- Blue Shield Advantage (HMO) — new for 2027
- Blue Shield AdvantageOptimum Plan (HMO)
- Blue Shield Inspire (HMO)
We are not listing premiums, copays, deductibles, provider networks, drug formularies or star ratings for any of these plans. Those details change year to year and are specific to each plan — look them up on medicare.gov or in the plan's own Evidence of Coverage.
What is new or not returning from Blue Shield of California in Orange County for 2027?
For 2027, Blue Shield of California is adding one new plan in Orange County — Blue Shield Advantage (HMO) — and is not discontinuing any of its current plans in the county.
If you are already enrolled in a Blue Shield plan that is coming back next year, you do not need to do anything to keep it. It renews automatically on Jan. 1, 2027, with whatever changes are described in your Annual Notice of Change. The ANOC is mailed each fall and spells out what is different for the coming year — the premium, the drug tiers, the copays, the network and any extra benefits.
How do I check a Blue Shield plan against my doctors and prescriptions before Dec. 7?
Use the Medicare Plan Finder at medicare.gov. It is the one tool that lets you enter your ZIP code, your specific medications and your pharmacy, and then see how each plan sold in Orange County would cover them.
A step-by-step approach that works for most people:
1. Pull out your ANOC and your current member ID card so you know what you have today. 2. Make a list of your prescriptions with the exact dose and how often you take them. 3. On medicare.gov, search plans in your ZIP code and add your drug list and pharmacy; the tool will estimate your yearly drug costs under each plan. 4. For doctors and hospitals, call the plan directly or check its online provider directory — networks can change mid-year, so confirm your providers are in-network for 2027. 5. If anything is unclear, call 1-800-MEDICARE (TTY 1-877-486-2048), available 24 hours a day, 7 days a week.
What else is changing in Medicare Part D for 2027?
Two Part D figures are already confirmed by CMS for 2027. The out-of-pocket cap on covered Part D drugs rises to $2,400 in 2027 (up from $2,100 in 2026). The maximum Part D deductible a plan can charge rises to $700 in 2027 (up from $615 in 2026). The national base beneficiary premium, which is a formula input and not what any specific plan charges, is $41.33 for 2027.
The coverage gap (the old "donut hole") was eliminated in 2025, so Part D now has three phases: deductible, initial coverage, and catastrophic. Once you hit the out-of-pocket cap, you pay $0 for covered Part D drugs for the rest of the year. The Medicare Prescription Payment Plan remains available as an option to spread your drug out-of-pocket costs across the calendar year in monthly installments.
CMS has not yet announced the 2027 Part B standard premium and deductible, or the 2027 IRMAA income brackets. Those are usually released later in the fall. Until then, do not rely on projections.
When can I make a change for 2027 coverage?
The Annual Enrollment Period runs from Oct. 15 through Dec. 7, 2026. Any change you make in that window takes effect Jan. 1, 2027. If you do nothing, your current plan renews for 2027 (if it is being offered again) with the changes in its ANOC.
If you are in a Medicare Advantage plan on Jan. 1, there is also the Medicare Advantage Open Enrollment Period from Jan. 1 through March 31, 2027. During that window you can switch to a different Medicare Advantage plan one time, or go back to Original Medicare and add a Part D plan.
