Best Medicare Plans in Charleston County, SC (2026)

Best Medicare Advantage Plans in Charleston County (2026)

Charleston County has over 40 Medicare Advantage plans available for 2026. I have narrowed it down to the four that deliver the best combination of cost, coverage, network access, and extra benefits. These plans cover the major hospital systems in the area, including MUSC Health and Roper St. Francis.

1. Humana Gold Plus HMO - Best Overall

Humana's top-tier HMO plan earns a 4.5-star rating from CMS, the highest in Charleston County for 2026. The $0 monthly premium is hard to beat, and the $0 primary care copay means routine visits cost you nothing. The $5,900 maximum out-of-pocket is below the federal limit and competitive with plans that charge a monthly premium. Dental coverage includes preventive services plus a $1,500 annual allowance for comprehensive procedures like crowns and root canals. The SilverSneakers fitness benefit gives you free gym access at participating locations. MUSC and Roper St. Francis are both in-network. The main limitation is HMO structure: you need a primary care referral for specialists, and non-emergency out-of-network care is not covered. For people who are comfortable staying in-network and getting referrals, this is the plan to beat in Charleston County.

2. Aetna Medicare Eagle PPO - Best PPO Option

If you want the flexibility to see specialists without referrals or visit out-of-network providers, the Aetna Eagle PPO is the strongest option. The $0 monthly premium keeps costs low, though the $7,550 maximum out-of-pocket is higher than the Humana HMO. The 4.0-star CMS rating reflects solid plan performance. Primary care copays are $0 to $10 depending on the provider. The $1,000 dental allowance and $100 vision allowance are competitive. Renew Active fitness is included. The PPO structure means you can see any provider who accepts the plan, in or out of network, without referrals. Out-of-network costs are higher but still covered. For people who see specialists at both MUSC and providers outside the tri-county area, or who spend part of the year traveling, the PPO flexibility is worth the trade-off of a higher out-of-pocket maximum.

3. Wellcare Value Script HMO - Best Budget Option

Wellcare offers the lowest-cost entry point among the top-rated plans. The $0 premium and $5 primary care copay keep monthly costs near zero. The $6,700 maximum out-of-pocket is moderate. Wellcare's 4.0-star rating is solid, and the plan covers MUSC and Roper St. Francis. Dental and vision benefits are basic - preventive dental and a $100 eyewear allowance - but adequate for people who do not need extensive dental work. SilverSneakers is included. The $250 annual deductible is the only upfront cost. Wellcare is a good choice for healthy beneficiaries who want minimal monthly expense and are willing to accept basic extras in exchange for the lowest possible costs when they do not use much healthcare.

4. UnitedHealthcare AARP Medicare Advantage PPO - Best Extras Package

UnitedHealthcare's AARP-branded PPO plan stands out for the comprehensiveness of its extra benefits. The $29 monthly premium is higher than the other options, but you get a $2,000 annual dental allowance, a $200 vision allowance, and up to $2,500 per ear for hearing aids - the most generous hearing benefit in Charleston County. The $5,500 maximum out-of-pocket is the lowest among plans reviewed here. The $0 primary care copay and $25 specialist copay are competitive. Renew Active fitness is included. The 3.5-star rating is lower than the other options, reflecting some member satisfaction metrics that lag behind Humana and Aetna. For people who need hearing aids, significant dental work, or value comprehensive extras, the UnitedHealthcare plan delivers the most total benefit value despite the modest premium.

Best Medigap Plans in Charleston County (2026)

Medigap plans are standardized by letter, so the benefits of Plan G from one carrier are identical to Plan G from another carrier. The differences are price, rate increase history, and customer service. In South Carolina, Plans G and N are the most popular. Here are the three best options for Charleston County residents.

1. Mutual of Omaha Plan G - Best Value

Mutual of Omaha consistently offers the lowest or near-lowest Plan G premiums in Charleston County. At approximately $128 per month for a 65-year-old, it undercuts most competitors by $10 to $30 per month. The rate increase history has been moderate at 3 to 5 percent per year, which is in line with the industry average. Mutual of Omaha has strong financial ratings and a long track record in the Medigap market. Because Plan G benefits are identical regardless of carrier, the lower premium is pure savings. Over a 10-year period, a $15 per month premium advantage compounds to $1,800 in savings. For people who want the most comprehensive Medigap coverage at the best price, Mutual of Omaha Plan G is the top choice in Charleston County.

2. BlueCross BlueShield of SC Plan G - Best Brand Recognition

BlueCross BlueShield of South Carolina is the most recognized insurance name in the state. Their Plan G premium at approximately $142 per month for a 65-year-old is competitive, though not the cheapest. The brand carries weight with some providers and members who value familiarity. Rate increases have averaged 4 to 6 percent per year over the past five years, slightly above industry average but not dramatically so. BlueCross has the largest customer service infrastructure in South Carolina and offices throughout the state. For people who value the BlueCross name and are willing to pay a modest premium difference for it, this is a solid choice. The benefits are identical to Mutual of Omaha Plan G.

3. Mutual of Omaha Plan N - Best Budget Medigap

Plan N is the budget-friendly Medigap option. At approximately $95 per month for a 65-year-old from Mutual of Omaha, it costs about $33 less per month than their Plan G. The trade-off is that Plan N has $20 copays for office visits and $50 copays for ER visits that do not result in hospital admission. Plan N also does not cover Part B excess charges, though this is rarely an issue in South Carolina because the vast majority of doctors accept Medicare assignment. For healthy beneficiaries who see their doctor a few times a year and want Medigap-level protection against major costs, Plan N saves $396 per year in premiums compared to Plan G. If you see the doctor more than 10 to 15 times per year, the copays start to erode that savings and Plan G becomes the better deal.

Best Part D Prescription Drug Plans in Charleston County (2026)

The best Part D plan for you depends entirely on your medications. A plan that is perfect for someone taking lisinopril and metformin may be terrible for someone taking Eliquis and Jardiance. That said, these three plans consistently rank well for common medication profiles in Charleston County.

1. SilverScript Choice - Best for Generic Medications

At $7.50 per month with a $0 deductible, SilverScript Choice is the lowest-cost option for people who take only generic medications. Tier 1 preferred generics are $0 copay, and standard generics are $4. The pharmacy network includes CVS, Walgreens, and Walmart. Mail-order options are available for 90-day supplies. If you take two or three generic medications and nothing else, this plan typically results in the lowest total annual cost. The limitation is that brand-name drug coverage is more expensive than some competitors, so this plan works best for people on an all-generic regimen.

2. Wellcare Value Script PDP - Best for Broad Coverage

Wellcare's standalone Part D plan at $13 per month strikes a balance between premium cost and formulary breadth. The $250 annual deductible applies before coverage kicks in, but the drug tiers are competitive once you pass it. Preferred generics are $1, standard generics are $5, and preferred brands are $42. The pharmacy network covers most major chains. This plan works well for people who take a mix of generics and one or two brand-name medications. The deductible is the main downside, but for people with moderate medication needs, the overall annual cost is often lower than plans with higher premiums and no deductible.

3. AARP MedicareRx Preferred - Best for Brand-Name Drugs

At $31.40 per month, this is the most expensive Part D option on the list, but it offers the best coverage for people who take multiple brand-name medications. The $0 deductible means coverage starts immediately. Preferred brand copays of $38 and non-preferred brand coinsurance of 33 percent are lower than most competitors. The plan also offers gap coverage for preferred generics, which extends savings beyond the initial coverage phase. The mail-order program through OptumRx offers preferred pricing on 90-day supplies. If you take Eliquis, Jardiance, Ozempic, or other expensive brand-name drugs, this plan's lower per-prescription costs often more than offset the higher premium. I always run the specific numbers to verify.

How to Choose the Right Medicare Plan in Charleston County

Rankings and comparisons are useful starting points, but the right plan for you is the one that covers your specific doctors, your specific medications, and fits your specific budget. Here is how to narrow it down.

Step 1: List your doctors

Write down every doctor you see regularly, including your primary care physician, specialists, and any facilities where you receive care. If your cardiologist is at MUSC and your orthopedist is at Roper, both systems need to be in-network. If you travel to see a specialist in Columbia or out of state, you need a PPO or Medigap, not an HMO.

Step 2: List your medications

Write down every prescription medication, including dosage and how often you take it. This list determines which Part D plan or Medicare Advantage drug coverage costs you the least. A medication that is Tier 2 on one plan can be Tier 4 on another, changing your annual cost by hundreds of dollars.

Step 3: Estimate your healthcare usage

Think about how often you see doctors, whether you have any procedures planned, and how your health has been trending. If you are healthy and rarely use healthcare, a low-premium Medicare Advantage HMO or Medigap Plan N makes financial sense. If you have chronic conditions, see multiple specialists, or anticipate surgery, the predictability of Medigap Plan G is worth the higher premium.

Step 4: Calculate total annual cost, not just premiums

The cheapest premium does not mean the cheapest plan. Add up premiums, deductibles, expected copays and coinsurance, and prescription drug costs to get the total annual cost. A $0 premium Medicare Advantage plan with a $300 specialist copay costs more than a $140 per month Medigap plan with $0 specialist costs if you see four specialists regularly.
