The South Carolina Coverage Gap Explained

The coverage gap in South Carolina affects roughly 200,000 adults who earn too much for Medicaid but too little for ACA marketplace subsidies. If you’re in this gap, you’re caught in a policy failure that isn’t your fault: the Affordable Care Act assumed every state would expand Medicaid, and South Carolina chose not to. Here’s what that means for real people in the Lowcountry, why it exists, and what you can actually do about it.

What the Coverage Gap Is

The ACA was designed as a two-part system:

Medicaid would cover everyone below 138% of the Federal Poverty Level
Marketplace subsidies would help everyone from 100% to 400% FPL

In states that expanded Medicaid, there is no gap. People below 138% FPL get Medicaid. People above 100% FPL get marketplace subsidies. The system works as intended.

South Carolina did not expand Medicaid. The state’s traditional Medicaid program covers only specific categories: children, pregnant women, elderly adults, people with disabilities, and parents with very low income (generally below 67% FPL for parents, which is roughly $10,100 for a single parent with one child).

That leaves a gap: adults earning between the Medicaid eligibility ceiling and 100% FPL ($15,060 for an individual in 2026). These people earn too much for SC Medicaid and too little for marketplace subsidies.

Who falls in the gap:

Single adults without children earning $0-$15,059/year
Parents earning above Medicaid limits but below 100% FPL
Part-time workers without employer coverage
Gig workers, seasonal workers, and day laborers
Adults caring for family members who can’t work full-time

In the Lowcountry, this includes restaurant workers in downtown Charleston, seasonal tourism employees, agricultural workers, retail workers on limited hours, and many more.

Why South Carolina Hasn’t Expanded Medicaid

This is a political question, not a healthcare question. The short answer: the SC legislature and governor have consistently opposed Medicaid expansion since the ACA passed in 2010.

Arguments made against expansion:

Cost concerns: While the federal government pays 90% of expansion costs, the state’s 10% share would still be hundreds of millions annually
Philosophical opposition to expanding government healthcare programs
Concerns about dependency on federal funding that could be reduced in future legislation
Preference for market-based solutions

Arguments for expansion:

Federal government covers 90% of costs
Hospitals (including rural hospitals) lose money on uncompensated care for uninsured patients
Economic analysis shows expansion would bring billions in federal dollars to SC
Neighboring states that expanded (Virginia, Louisiana) have seen positive outcomes
Reduces the number of uninsured residents and improves health outcomes

Current status (2026): As of this writing, South Carolina has not expanded Medicaid and no active legislation is likely to change this in the near term. Several proposals have been introduced and failed over the years. The political dynamics would need to shift significantly for expansion to pass.

What You Can Actually Do If You’re in the Gap

Being in the coverage gap doesn’t mean you have zero options. The options are limited and imperfect, but they exist:

1. Community Health Centers Federally qualified health centers provide primary care on a sliding-scale fee basis regardless of insurance status or ability to pay. In the Lowcountry:

Fetter Health Care Network: Multiple locations in Charleston, North Charleston, and the surrounding area. Services include primary care, dental, behavioral health, and pharmacy. Fees are based on income. you might pay $20-$40 for a visit that would cost $200 elsewhere.
Franklin C. Fetter Family Health Center: Part of the Fetter network, serving the greater Charleston community.

2. Hospital Financial Assistance Federal law requires nonprofit hospitals to have financial assistance policies. If you need hospital care:

MUSC Health Financial Assistance: Covers patients at or below 200% FPL for most services. Apply before or after receiving care. Contact financial counseling at 843-792-3682.
Roper St. Francis Charity Care: Income-based financial assistance for uninsured and underinsured patients.
Trident Medical Center: HCA’s financial assistance program provides discounts based on income.

Apply for financial assistance before you receive care if possible, or immediately after. Don’t ignore hospital bills. they go to collections, which damages your credit. Apply for assistance first.

3. Free Clinics Several free clinics serve the Lowcountry:

Volunteers in Medicine: Provides free medical and dental care to qualifying uninsured adults in the Charleston area
Barrier Islands Free Medical Clinic: Serves uninsured residents of Johns Island, Wadmalaw Island, and James Island

4. Prescription Assistance

NeedyMeds.org: Database of patient assistance programs, discount cards, and free clinics
RxAssist.org: Full database of pharmaceutical manufacturer assistance programs
Mark Cuban Cost Plus Drugs: Transparent pricing, often dramatically cheaper than retail pharmacies
GoodRx: Free discount coupons that work at most Summerville pharmacies
$4 generic lists: Walmart, Publix, and other chains offer select generics for $4/30-day supply

5. Behavioral Health Resources

Charleston Dorchester Mental Health Center: Sliding-scale counseling and psychiatric services
NAMI South Carolina: Support groups and resources for mental health conditions
988 Suicide and Crisis Lifeline: Call or text 988 for immediate mental health crisis support

6. Check for Medicaid Eligibility Changes Your Medicaid eligibility can change with life events:

Becoming pregnant qualifies you for Medicaid regardless of the gap
Developing a qualifying disability can make you eligible
Having a child or changing custody arrangements can affect eligibility
Reaching age 65 makes you eligible for Medicare

The Health Consequences of Being Uninsured

Being in the coverage gap has real health consequences that compound over time:

Preventive care gets skipped: screenings, vaccinations, and checkups don’t happen
Chronic conditions go unmanaged: diabetes, hypertension, and mental health conditions worsen without ongoing care
Emergency rooms become primary care: more expensive, less effective, and often too late
Prescription medications are unaffordable: people ration insulin, skip blood pressure meds, and avoid necessary treatments
Dental and vision care are deferred: problems that are cheap to fix early become expensive emergencies later

This isn’t abstract. I sit across the table from people in the Lowcountry who haven’t seen a doctor in three years because they can’t afford it. They’re not irresponsible. they’re trapped in a gap that shouldn’t exist.

If Your Income Changes

The coverage gap is income-specific. If your income increases above 100% FPL ($15,060/year for an individual), you become eligible for marketplace subsidies. At that income level, the subsidies are substantial. you may qualify for a Silver plan with a $0 monthly premium and minimal copays through Cost-Sharing Reductions.

This creates a perverse incentive where earning slightly more money dramatically improves your healthcare situation. A person earning $14,000 has no affordable coverage option. A person earning $16,000 can get comprehensive insurance for near-zero cost.

If you’re close to the threshold, it’s worth exploring whether additional work, a different job, or other income could push you above 100% FPL. I know that sounds like “just earn more money,” and I recognize how inadequate that advice feels. But the difference between $14,000 and $16,000 in annual income can be the difference between no healthcare and full coverage.

Frequently Asked Questions

Am I in the coverage gap?

If you’re an adult in SC earning below 100% FPL ($15,060 individual), not eligible for Medicaid (not pregnant, not disabled, not elderly, not a qualifying parent), and not covered by employer insurance, you’re likely in the gap.

Is there a penalty for being uninsured in South Carolina?

No. The federal individual mandate penalty was reduced to $0 in 2019, and South Carolina has no state-level mandate or penalty.

Will South Carolina ever expand Medicaid?

This requires action by the state legislature and governor. Several proposals have been introduced over the years. As of 2026, expansion has not passed and there is no indication it will in the immediate future.

Can I still go to the emergency room if I’m uninsured?

Yes. Federal EMTALA law requires emergency rooms to treat you regardless of insurance or ability to pay. You will receive a bill, but you will receive treatment. Apply for the hospital’s financial assistance program.

What if I’m in the gap and need surgery?

Community health centers can refer you to specialists. Hospital financial assistance programs may cover surgical care. MUSC’s charity care program is one resource. Don’t assume you can’t get care. apply for assistance and advocate for yourself.

I don’t stop until you’re covered. If you’re in the coverage gap, I can’t fix the policy, but I can help you find every resource available. And if your income situation changes, I’ll get you enrolled the day you become eligible. I’m in Summerville.
