A plan can be listed because it was renumbered or replaced, not only because a company is leaving the county. When the same company keeps other plans there, members are usually moved to a replacement plan. Your plan should send you a notice, and Medicare’s Annual Enrollment Period (October 15 to December 7) is when you can compare and switch. “People enrolled” is the number enrolled in that plan today (CMS hides counts of 10 or fewer).
