Which 2027 plans do its members move into?

The crosswalk names the plans but not which member goes to which; the counties show where each is sold, and your Annual Notice of Change names yours.

2027 plan	Sold in	Its members there, Sept. 2026	Premium 2027	Limit 2027
Blue Cross Medicare Advantage Dual Care PlusH3822-017	31 of its counties	3,069	$0	$9,850
Blue Cross Medicare Advantage Dual CareH3822-018	31 of its counties	3,069	$0	$5,000

Where several of the plans are sold in the same county, the member counts overlap, so they add up to more than the plan's members.
