What to do if you have a Aetna (CVS Health) plan

  1. Read the notice from Aetna (CVS Health). It names the plan that is ending and your options.
  2. Compare 2027 options before December 7, including other Medicare Advantage plans, or Original Medicare with a Medicare Supplement and a Part D drug plan.
  3. Check that your doctors, hospitals and prescriptions are covered by any plan you consider.
  4. Free, unbiased help: CLAIM (Community Leaders Assisting the Insured of Missouri) at 800-390-3330, or Medicare.gov, 1-800-MEDICARE.
Is my Aetna (CVS Health) plan ending in Missouri?

Check the list above for your plan name or plan ID. A plan can be listed because it was renumbered or replaced, so your plan notice is the final word. Aetna (CVS Health) must notify you if your plan is not renewing.

When can I pick a new plan?

The Annual Enrollment Period runs October 15 to December 7, and new coverage starts January 1. People whose plan is not renewing generally get extra time afterward. Confirm your dates with Medicare.gov or your plan notice.

Do I have to enroll if I call?

No. Calling is a conversation about your options, and you are never required to enroll.
