Health Insurance in Williamsburg County, SC: 2027 Plans, Prices & Hospitals (Kingstree)

If you buy your own health insurance in Williamsburg County, you have three Marketplace insurance companies to choose from for 2027: Ambetter from Absolute Total Care, BlueCross BlueShield of SC and UnitedHealthcare, offering 57 plans in all. The silver plan your tax credit is based on costs $623 a month for a 40-year-old at full price before tax credits, up from $521 in 2026 (+19.7%). Molina is leaving the county.

MUSC Health Black River is in every network in our 2027 data. UnitedHealthcare's hospital network isn't in our data, so we check it in UnitedHealthcare's directory.

Your tax credit is sized from one silver plan, the second-lowest-cost silver plan in the county. Its price rose 19.7% at every age.

Each insurance company's lowest-priced plan at each metal level:

Ambetter has the lowest silver price, $609 at age 40, which is $14 below the silver plan your tax credit is based on. Because your tax credit is tied to that $623 plan, a buyer with a tax credit who picks the lowest-priced silver pays a little less than they would for the $623 plan after the tax credit. UnitedHealthcare is the highest-priced insurance company here at every metal level it sells.

Molina is leaving. Molina sold 12 plans here in 2026 and has none for 2027, so Molina members need a new plan. Our article on Molina's exit walks through the options.

Plan counts changed. Ambetter went from 9 plans to 17; BCBS went from 31 plans to 23; UnitedHealthcare stays at 17 plans. BCBS kept its Blue Cooper HMO and statewide EPO plans.

The silver plan your tax credit is based on changed. In 2026 it was Ambetter Focused Silver. In 2027 it is Ambetter Signature Silver. The insurance company is the same, but the plan and its price are different, and your tax credit moves with that plan. That is why we tell clients not to auto-renew without checking.

The table also lists hospitals in neighboring counties from our network data.

Networks and covered drug lists can change; we verify with the insurance company before you enroll. Last verified: November 2026.

• The BCBS EPO includes all four hospitals on this list, with restrictions at Tidelands Georgetown Memorial.
• The Blue Cooper HMO includes MUSC Health Black River and MUSC Health Florence Medical Center but not McLeod Health Clarendon or Tidelands Georgetown Memorial.
• Ambetter includes MUSC Health Black River, MUSC Health Florence Medical Center and McLeod Health Clarendon but not Tidelands Georgetown Memorial.
• UnitedHealthcare's network isn't in our hospital data. Check UnitedHealthcare's directory for each hospital and doctor before you enroll.
• Where a hospital is in-network with restrictions, confirm your specific doctor or service with the insurance company before you enroll.

Every plan here is an HMO except the BCBS BlueEssentials and BlueConnect EPOs; the SC Marketplace has no PPOs. Neither type covers out-of-network care except emergencies. Our guide to BCBS networks covers the Blue Cooper HMO and the EPO.

You rarely see a doctor and want the lowest premium. BCBS Blue Cooper Bronze 2 is the cheapest plan at $463 for a 40-year-old, but its $10,600 deductible equals its yearly limit on what you pay, so beyond preventive care it pays little until you spend $10,600. Of the hospitals above, it includes MUSC Health Black River and MUSC Health Florence Medical Center.

You want the lowest silver price. Ambetter Streamlined Silver is $609 at age 40, with a $4,700 deductible, an $11,300 yearly limit on what you pay, $20 primary care visits and $3 generics. Of the hospitals above, it includes MUSC Health Black River, MUSC Health Florence Medical Center and McLeod Health Clarendon.

You expect regular care and want a low deductible. Ambetter Signature Gold is $651 at age 40, $28 more than the silver plan your tax credit is based on, with a $2,500 deductible, an $8,600 yearly limit on what you pay, $30 primary care visits and $15 generics. Of the hospitals above, it includes MUSC Health Black River, MUSC Health Florence Medical Center and McLeod Health Clarendon. If you need a hospital it leaves out, BCBS's lowest gold is $716.

You want the widest choice of SC hospitals. BCBS's BlueEssentials and BlueConnect plans use a statewide EPO network, which can matter if you get care outside the county. BCBS also sells the Blue Cooper HMO here, which uses a smaller regional network.

You're thinking about UnitedHealthcare. UnitedHealthcare's lowest silver here is $860 at age 40, compared with $609 for the county's lowest silver. Your tax credit is the same whichever insurance company you choose, because it's set by one silver plan, not by the plan you pick.

Your income is lower. Below 250% of the federal poverty level, silver plans come with cost-sharing reductions that lower the deductible and the yearly limit on what you pay. Our cost-sharing reductions guide explains how it works.
