Medicare in South Carolina

Medicare enrollment in South Carolina

As of mid-2023, there were 1,183,019 people enrolled in Medicare in South Carolina. That’s about 22% of South Carolina’s population enrolled in Medicare, compared with about 19% of the United States population enrolled in Medicare.

People become eligible for Medicare either due to their age (turning 65) or due to a disability. In South Carolina, 13% of Medicare beneficiaries were eligible due to a disability as of mid-2023, while the rest were eligible due to their age. Nationwide, more than 88% of all Medicare beneficiaries are eligible due to age.

Medicare Advantage in South Carolina

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 private Medicare Advantage plan. Medicare Advantage plans provide all of the same covered healthcare benefits as Original Medicare (hospital coverage and medical/physician coverage), but the out-of-pocket costs can be very different, as Advantage plans set their own coinsurance, deductibles, and copays.

Most Advantage plans provide members with integrated Part D coverage for prescription drugs, as well as extra programs like dental and vision coverage. But Advantage plans also tend to have local 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.

A quarter of South Carolina’s Medicare beneficiaries were covered by Medicare Advantage plans as of 2018, compared with an average of 34% nationwide. 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 private coverage (nationwide, about 48% of Medicare beneficiaries had private Advantage plans at that point).

There are Medicare Advantage plans for sale in all 46 counties in South Carolina in 2023, with plan availability ranging from 49 plans in Darlington County to 76 in Greenville County. Medicare Advantage plan availability has increased significantly in some parts of the state in recent years; as of 2019, there were only six plans available in Darlington County, and 41 in Greenville County.

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.

Medigap in South Carolina

Original Medicare beneficiaries have the option to purchase Medigap plans (also known as Medicare supplement plans), with the Medigap plan covering some or all of the out-of-pocket costs (for coinsurance 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 ends up with extensive medical conditions. Medigap plans are issued by private 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.

There were 280,448 people enrolled in private Medigap plans in South Carolina in 2021, according to an AHIP analysis. There were 72 insurers offering Medigap plans in South Carolina in 2023.

But unlike Medicare Advantage and Medicare Part D 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 private Medigap plans for enrollees who are under the age of 65, but South Carolina is not among them.

Because Medigap insurers in South Carolina are not required to issue coverage to people under 65, nearly all of them only make their plans available to applicants who are 65+. But, United American Insurance, one of the 72 insurers that offer Medigap plans in South Carolina, does offer coverage to people who are under 65 and enrolled in Medicare as a result of a disability. According to Medicare’s plan finder tool, Transamerica Life Insurance Company also offers Medigap policies to South Carolina applicants who are under age 65.

Instead of requiring private 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 Plan A, Plan C, and Plan D; note that under federal rules, Plan C is only available to people who became eligible for Medicare prior to 2020.

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 very high cost: In 2022, Plan A is $1,024.01 per month, Plan C (only available to beneficiaries who became eligible for Medicare prior to 2020) is $1,317,47 per month, and Plan D is $1,206.49 per month. Although Blue Cross Blue Shield of South Carolina is the administrator for SCHIP, these are not BCBSSC plans; SCHIP is providing the coverage, and only using BCBSSC to administer the policies.

For perspective, premiums for private Medigap Plan A for a 65-year-old non-smoking female range from $85/month to $361/month in 2023, according to Medicare’s plan finder tool. In states that have enacted laws requiring private 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 private 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 private Medigap plans, 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 normal six-month guaranteed-issue open enrollment period for Medigap when they turn 65, and can switch to a much lower-priced plan at that point, selecting from among all of the available Medigap options in the state.

Medicare Part D in South Carolina

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 need coverage under a Medicare Medicare Part D 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 plan options for sale in South Carolina, with premiums that start as low as $5.70/month.

Part D coverage in South Carolina is roughly equally split between stand-alone plans and MA-PD plans: 437,770 Medicare beneficiaries in South Carolina were covered under stand-alone Medicare Part D plans as of mid-2023, and an additional 477,295 had Medicare Part D coverage as part of their Medicare Advantage plans.

Medicare Part D enrollment is available on the same schedule that applies to Medicare Advantage plans. Beneficiaries can pick a Medicare Part D plan when they’re first eligible for Medicare, and can switch to a different plan during the fall enrollment window, 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.
