What CMS's lists show for Aetna (CVS Health) in California
CMS's 2027 plan list does not show 12 Aetna (CVS Health) plans in 12 California counties that CMS's 2026 plan list showed them in.
It also does not show 1 stand-alone Part D prescription drug plan from Aetna (CVS Health) in California.
CMS reports at least 198,706 people enrolled in these plans as of September 2026. CMS hides enrollment counts of 10 or fewer, so "at least" means the real number can be higher.
That is what CMS's data shows. It is not a notice about your coverage, and your plan's written notice is what tells you what is happening to it.

Does Aetna (CVS Health) still have a plan where you live?
It depends on the plan. For 8 of the 13 plans on this page, CMS's 2027 plan list still shows other Aetna (CVS Health) plans in every county named, and a member is often moved to another plan with the same company. For the other 5, there is at least one county where CMS's 2027 plan list shows no Aetna (CVS Health) plan at all, and a member living there would generally need to choose a new plan.
CMS reports at least 163,279 people enrolled in these plans in counties where CMS's 2027 plan list shows no Aetna (CVS Health) plan at all.
The status under each plan below says which applies. Your plan's written notice is the thing to check.
What you can do
- Find the written notice from your Aetna (CVS Health) plan and read what it says. If you are not sure you have one, call the plan, using the number on your member card, and ask.
- Confirm with the plan which plan you would be in for 2027, and check that the doctors and drugs you use are covered before you decide anything.
- Check your dates. The Annual Enrollment Period generally runs October 15 to December 7, with new coverage starting January 1. People whose plan is not renewing generally get a Special Enrollment Period that runs from December 8 through the end of February. Confirm your own dates with your plan or with us.
- Or talk it through with a licensed agent here: leave your number below or call 855-367-1095. We do not offer every plan, so we will tell you plainly what we can and cannot help with.
Where this comes from, and its limits
This page was built from public CMS files: CMS CY2026 Landscape (Sept 2025 release), CMS CY2027 Landscape (Sept 2026 release), and CMS Monthly Enrollment by Contract/Plan/State/County, Sept 2026. A plan is listed when CMS's 2026 Landscape lists a plan in a county and CMS's 2027 Landscape does not list any segment of that plan there. Member counts are the people CMS reports enrolled in the plan in those counties in September 2026. CMS hides enrollment counts of 10 or fewer, so "at least" means the real number can be higher.
This is what CMS's files show. It is not a notice about any one person's coverage, and CMS can correct or update its files after we built this page. Your plan's written notice is what tells you what is happening to your coverage, so check it and confirm with the plan.

Common questions
If a plan is on this list, will it not be there next year?
Not necessarily, and this page cannot tell you that about your plan. It shows only that CMS's 2027 plan list does not show a Aetna (CVS Health) plan in a California county where CMS's 2026 plan list showed it. Plans are sometimes renumbered or replaced, and a company often moves members to another of its plans. The written notice from your plan is what tells you what is happening to your coverage, so check it and confirm with the plan.
When can I choose a different plan?
The Annual Enrollment Period generally runs October 15 to December 7, with new coverage starting January 1. People whose plan is not renewing generally get a Special Enrollment Period that runs from December 8 through the end of February. Check your own dates with your plan or with us.
Who can help me compare my options?

Where do these numbers come from?
CMS CY2026 Landscape (Sept 2025 release), CMS CY2027 Landscape (Sept 2026 release), and CMS Monthly Enrollment by Contract/Plan/State/County, Sept 2026. CMS hides enrollment counts of 10 or fewer, so "at least" means the real number can be higher.
What does this say about Aetna (CVS Health) in California?
Only what CMS's files show. This page lists the plans and counties where CMS's 2027 plan list does not show a Aetna (CVS Health) plan that CMS's 2026 list showed. The section above says whether CMS's 2027 list still shows other Aetna (CVS Health) plans in the same counties.
