MyMedicarePlans.org is an independent consumer site, not Aetna and not Medicare. Aetna is one of 16 carriers offering Medicare Advantage plans in Orange County for 2027; all carriers combined offer 111 plans in the county next year.
What Aetna Medicare Advantage plans are available in Santa Ana for 2027?
Santa Ana is in Orange County, where Aetna will offer six Medicare Advantage plans for 2027. By type, that is five HMO plans and one HMO-POS plan. Five of the six include Part D drug coverage; one does not. Aetna is not offering a PPO in the county next year, which is a change from 2026.
The full roster is in the table below. In alphabetical order, Aetna's 2027 plans are: Aetna Medicare Chronic Care (HMO C-SNP), Aetna Medicare Eagle (HMO), Aetna Medicare Prime (HMO), Aetna Medicare Signature (HMO), Aetna Medicare Signature Extra (HMO), and Aetna Medicare Signature Legacy (HMO).
Does Aetna offer a Special Needs Plan in Orange County for 2027?
Yes — one. Aetna Medicare Chronic Care (HMO C-SNP) is a Chronic Condition Special Needs Plan, and it is new for 2027. C-SNPs are built around people living with specific chronic conditions; eligibility depends on the condition the plan is designed for, which the plan documents will spell out. Aetna is not offering a Dual Eligible SNP (D-SNP) or an Institutional SNP (I-SNP) in the county for 2027.
What is new, renamed or not returning in Aetna's Santa Ana lineup for 2027?
Two Aetna plans are new in Orange County for 2027: Aetna Medicare Chronic Care (HMO C-SNP) and Aetna Medicare Eagle (HMO). Two existing plans have been renamed. Aetna Medicare Prime, which was offered as an HMO-POS in 2026, carries the HMO label in its 2027 name. And a plan now called Aetna Medicare Signature Legacy (HMO) was previously part of the Aetna Medicare Signature (HMO) line. A renamed plan is still a plan change — the ANOC your plan mailed before October 15 shows what moved, including network, drug list and cost changes for 2027.
Three Aetna plans offered in 2026 are not returning for 2027. If one of them is yours, Aetna will have sent a non-renewal notice explaining your options and your Special Enrollment Period rights. You will not lose Medicare — your Part A and Part B stay in place — but you do need to pick a new Medicare Advantage plan or return to Original Medicare before coverage changes on January 1, 2027.
How do I check an Aetna plan against my doctors and prescriptions before December 7?
Use the Medicare Plan Finder at medicare.gov. You can enter your ZIP code, add your prescriptions and pharmacies, and see each plan's drug costs for the coming year side by side. For doctors and hospitals, check the plan's own provider directory on Aetna's website, or call the number on the plan materials, because a Plan Finder listing does not confirm that a specific physician is in network.
A short checklist that works for any plan:
- Pull out your current plan's ANOC and read the "changes for next year" summary.
- List every prescription, dose and pharmacy you use.
- List the doctors, specialists and hospitals you want to keep.
- Run each candidate plan through medicare.gov, then confirm the network by calling the plan directly.
- If you want help from a live person at Medicare, call 1-800-MEDICARE (TTY 1-877-486-2048), available 24/7.
What Medicare dates and figures should Santa Ana residents keep in mind for 2027?
Annual Enrollment runs October 15 through December 7, 2026, for coverage that starts January 1, 2027. If you do nothing and your plan is offered again, it renews automatically with the changes described in the ANOC. If you are already in a Medicare Advantage plan on January 1, you also have the Medicare Advantage Open Enrollment Period from January 1 to March 31, 2027, to make one change.
A few program-level figures for context. For 2027, CMS has confirmed the Part D out-of-pocket cap rises to $2,400 (up from $2,100 in 2026) and the Part D maximum deductible rises to $700 (up from $615 in 2026). The 2027 Part B standard premium and deductible, and the 2027 IRMAA income brackets, had not been announced as of this writing; CMS typically publishes those in the fall. The coverage gap ("donut hole") has been gone since 2025, and the Medicare Prescription Payment Plan remains available if you want to spread drug costs over the plan year.
