What can members do, and by when?

If you live in Anderson (SC), Greenville (SC), Laurens (SC), Oconee (SC), Pickens (SC), Spartanburg (SC), York (SC)

If you do nothing: You are moved into Aetna Medicare Signature on January 1, 2027.
October 15 to December 7, 2026: Open enrollment: choose another Medicare Advantage plan, or Original Medicare with a drug plan, instead.

If you live in Cherokee (SC), Lexington (SC), Richland (SC)

Your coverage: Ends December 31, 2026: Aetna Medicare Signature is not sold where you live.
October 15 to December 7, 2026: Open enrollment: join another Medicare Advantage plan, or Original Medicare with a drug plan. Coverage starts January 1, 2027.
December 8, 2026 to the end of February 2027: A special enrollment period because the plan is leaving: you can still join a plan, but coverage starts the first day of the month after you join, so choose by December 31 to have no gap.
If you do nothing: You are enrolled in Original Medicare when the plan ends, without a drug plan unless you join one (with Extra Help or full Medicaid, Medicare enrolls you in one).
Without a drug plan: Going 63 days or more in a row without drug coverage can mean a late enrollment penalty if you join a drug plan later; joining by the end of February keeps a January and February gap under 63 days, waiting longer does not.
