Frequently asked questions about Medicare in South Carolina
What is Medicare Advantage?
In most areas of the country, Medicare beneficiaries have the option to get their coverage through Original Medicare (directly from the federal government) or from a Medicare Advantage plan. Medicare Advantage plans provide all of the same covered healthcare benefits as Original Medicare (Part A – hospital coverage and Part B – medical/physician coverage), but the out-of-pocket costs can be very different, as Medicare Advantage plans set their own coinsurance, deductibles, and copays.
Many Medicare Advantage plans provide members with integrated Part D coverage for prescription drugs, as well as additional benefits like dental and vision coverage. But Medicare Advantage plans also tend to have localized service areas and much more limited provider networks than the nationwide provider access that Original Medicare offers. In short, there are pros and cons to either option.
More than a quarter of South Carolina’s Medicare beneficiaries were covered by Medicare Advantage plans as of 2018,9 compared with an average of 35% nationwide.10 The other three-quarters of South Carolina Medicare beneficiaries had instead opted for Original Medicare. But enrollment in Medicare Advantage plans has been steadily increasing nationwide and also in South Carolina. As of mid-2023, about 43% of South Carolina Medicare beneficiaries had Medicare Advantage coverage1 (nationwide, more than 48% of Medicare beneficiaries had Medicare Advantage plans at that point).11
There are Medicare Advantage plans in all 46 counties in South Carolina in 2023, with plan availability ranging from 34 plans in Darlington County to 52 plans in Greenville County.12
Medicare Advantage enrollment is available when beneficiaries first become eligible for Medicare, and also during the annual Medicare Annual Election Period, which runs from October 15 to December 7. This window gives Medicare beneficiaries the option to switch between Medicare Advantage and Original Medicare. People who are already enrolled in Medicare Advantage plans also have access to a Medicare Advantage Open Enrollment Period (January 1 to March 31) during which they can switch to any other Medicare Advantage plan that offers service in their area, or drop their Medicare Advantage plan and enroll in Original Medicare instead.13
What is Medigap?
Original Medicare beneficiaries have the option to purchase Medigap plans (also known as Medicare supplement insurance plans), with the Medigap plan covering some or all of the out-of-pocket costs (for coinsurance, copays and deductibles) that they would otherwise have to pay themselves when they need healthcare services. Original Medicare does not cap out-of-pocket costs, making Medigap coverage particularly valuable if a person has extensive medical conditions. Medigap plans are issued by insurers, but are standardized under federal rules, with ten different plan designs (differentiated by letters, A through N), making it fairly easy for consumers to compare one plan to another.14
There were 280,448 people enrolled in Medigap plans in South Carolina in 2021, according to America’s Health Insurance Plans (AHIP) analysis.4 There were 72 insurers offering Medigap plans in South Carolina in 2023.3
But unlike Medicare Advantage and Medicare Part D prescription drug plans, there is no annual open enrollment period for Medigap plans. Instead, federal regulations allow for a six-month guaranteed-issue window that begins when a person is 65 and enrolled in Medicare Part B. After that window has closed, Medigap insurers can use medical underwriting to determine an applicant’s premium and eligibility for coverage, unless the person qualifies for one of the limited guaranteed-issue rights.
And federal rules do not guarantee access to Medigap plans for people who are under 65 and enrolled in Medicare due to a disability. The majority of the states have rules ensuring at least some access to Medigap plans for enrollees who are under the age of 65, including South Carolina.15
Instead of requiring insurers to offer Medigap plans to people under 65, South Carolina has maintained its high-risk pool and offers three guaranteed-issue Medigap plans through the high-risk pool, for Medicare beneficiaries who are under age 65. The high-risk pool offers Medigap Plan A, Plan C, and Plan D;16 note that under federal rules, Medigap Plan C is only available to people who became eligible for Medicare prior to 2020.17
The South Carolina Health Insurance Pool (SCHIP) allows these enrollees to purchase Medigap coverage when they would otherwise be unable to do so, but at a higher cost: in 2023, Medigap Plan A is $1,024.01 per month,18 Medigap Plan C (only available to beneficiaries who became eligible for Medicare prior to 2020) is $1,317,47 per month,17 and Medigap Plan D is $1,206.49 per month.19
For perspective, premiums for Medigap Plan A for a 65-year-old non-smoking female ranges from $81/month to $601/month in 2023, according to Medicare’s plan finder tool.5 In states that have enacted laws requiring Medigap insurers to offer plans to people under the age of 65, the prices are typically higher, if the state allows it. But the high-risk pool Medigap premiums in South Carolina are several times more expensive than the average Medigap plan sold in the state. Several other states — Alaska, Iowa, Nebraska, New Mexico, North Dakota, Washington, and Wyoming — have maintained their high-risk pools to provide coverage to people with Medicare who are unable to obtain Medigap plans,20 although pricing on high-risk pool supplemental coverage varies considerably across those states.
People enrolled in SCHIP Medigap plans prior to turning 65 are granted the six-month guaranteed-issue Medigap Open Enrollment Period when they turn 65, and can switch to the lower-priced plan at that point, selecting from among all of the available Medigap options in the state.
What is Medicare Part D?
Original Medicare provides fairly comprehensive coverage, but it does not pay for outpatient prescription drugs. Medicare beneficiaries who have supplemental coverage from an employer (via a retiree plan or a plan sponsored by a current employer) often have prescription drug coverage integrated with the employer plan. But without a supplemental employer-sponsored plan or Medicaid, Medicare beneficiaries may need coverage under a Medicare Part D prescription drug plan. These can either be obtained as stand-alone coverage or as part of a Medicare Advantage plan that includes Medicare Part D prescription drug coverage (MA-PDs).
For 2023, there are 25 stand-alone Medicare Part D prescription drug plan options in South Carolina, with premiums that start as low as $5.70/month.6
Part D coverage in South Carolina is roughly equally split between stand-alone Medicare Part D prescription drug plans and Medicare Advantage Prescription Drug Plans (MA-PD): 438,172 Medicare beneficiaries in South Carolina were covered under stand-alone Medicare Part D prescription drug plans as of mid-2023, and an additional 479,152 had Medicare Part D prescription drug plan coverage as part of their Medicare Advantage plans.1
Medicare Part D prescription drug plan enrollment is available on the same schedule that applies to Medicare Advantage plans. Beneficiaries can pick a Medicare Part D prescription drug plan when they’re first eligible for Medicare, and can switch to a different plan during the fall Medicare Annual Election Period, from October 15 to December 7. Beneficiaries who have creditable drug coverage from another source can delay enrollment in Medicare Part D, but a delay without other creditable coverage in place will result in a late enrollment penalty once the beneficiary eventually enrolls in a Part D plan.
How does Medicaid provide financial assistance to Medicare beneficiaries in South Carolina?
Many Medicare beneficiaries receive financial assistance through Medicaid with the cost of Medicare premiums and services Medicare doesn’t cover – such as long-term care.

The South Carolina Department of Insurance can provide customer service and assistance with a wide range of insurance-related issues. The Department is responsible for regulating and overseeing Medigap insurers, and also licenses the insurers that sell Medicare Advantage and Medicare Part D prescription drug plans in the state (but most regulatory oversight of Medicare Advantage and Medicare Part D prescription drug plans is conducted at the federal level, by Centers for Medicare and Medicaid Services). The South Carolina Department of Insurance has a resource called “Making sense of health insurance after retirement,” which provides some useful information to people with Medicare and people who aren’t yet eligible for Medicare.
The Medicare Rights Center is a nationwide service that can provide a wide range of information and assistance related to Medicare enrollment, eligibility, and benefits.
