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).

Why your county matters for coverage
In South Carolina, the health plans you can choose depend on where you live. Medicare Advantage and Part D plans are offered by service area, usually county by county, and marketplace premiums and carriers are set by area as well. Living in Dorchester County means the options on this page apply to you, and plans in a neighboring county may differ.
- Medicare: I-CARE (Insurance Counseling Assistance and Referrals for Elders) gives free, unbiased counseling at 800-868-9095. Ask which plans serve Dorchester County specifically.
- Marketplace plans: shop through HealthCare.gov (federal Marketplace); enter your Dorchester County ZIP code to see what is offered.
- Medicaid: apply through Healthy Connections (SC Department of Health and Human Services).
South Carolina note: South Carolina's Medicare counseling program uses a distinctive name, I-CARE, rather than a generic SHIP label, and is run through the state's Office on Aging rather than the Department of Insurance -- worth knowing since some other states run this exact function directly out of their insurance regulator instead.
