South Carolina measures its prompt pay deadlines in business days, routes State Health Plan therapy through a separate behavioral health manager, and has no law requiring private insurers to cover telehealth. We bill mental health and psychiatric services for South Carolina counselors, therapists, social workers, and group practices, from the Upstate and the Midlands to Charleston, Beaufort, and the Grand Strand.
South Carolina is among the twelve states we serve. Talk with a billing specialist or call 800-820-0364.
South Carolina Billing at a Glance
- Business-day deadlines. Clean electronic claims must be paid within 20 business days and paper claims within 40.
- Limits on take-backs. Insurers must give 30 business days’ written notice before recovering an overpayment, and generally cannot start more than 18 months after paying.
- State employees use Companion Benefit Alternatives. Behavioral health for the PEBA State Health Plan is managed by CBA, with BlueCross BlueShield of South Carolina as the plan’s administrator.
- Medicaid expanded managed care in 2026. More members and services, including behavioral health, moved to the five MCOs on January 1, 2026.
- No commercial telehealth mandate. Coverage and payment for virtual sessions depend on each plan.
South Carolina’s Prompt Pay Rules
Under S.C. Code Section 38-59-230, an insurer must issue payment on a clean claim within 20 business days when it is submitted electronically, or within 40 business days on paper, counted from the later of receipt or the date the insurer has everything it needs to consider the claim clean. When payment is late, Section 38-59-240 requires interest at the state’s statutory rate from the 21st or 41st business day. Interest is not owed in certain cases, such as when a duplicate claim is filed while the original is still being processed, which is one reason we do not refile claims too early. These rules do not apply to claims under state or federal government programs, other than a government’s own employee plan, or to some national account programs.
South Carolina also regulates recoupments. Section 38-59-250 requires an insurer to send written notice at least 30 business days before trying to recover an overpayment, including the patient, service date, amount, and a reason for the change, along with appeal instructions when the contract has an appeal process. With limited exceptions, such as suspected fraud, self-insured plan requirements, or government programs, recovery cannot begin more than 18 months after the original payment. We track every recoupment notice and appeal the ones that do not meet these rules.
Healthy Connections Medicaid
The South Carolina Department of Health and Human Services runs Healthy Connections Medicaid. Most members are enrolled with one of five managed care organizations: Absolute Total Care, Healthy Blue by BlueChoice, Humana Healthy Horizons in South Carolina, Molina Healthcare, and First Choice by Select Health of South Carolina. Effective January 1, 2026, SCDHHS moved additional members and services, including behavioral health services, into managed care, while waiver and nursing facility services remain fee-for-service. Each MCO handles its own enrollment, authorization, and reimbursement, so the same service can have different rules depending on the member’s plan.
South Carolina did not expand Medicaid, so many working adults do not qualify, and coverage checks matter every month. SCDHHS also enrolls Licensed Independent Practitioners, such as LPCs, LISW-CPs, LMFTs, and psychologists, for certain behavioral health services. We handle SCDHHS enrollment and each MCO’s credentialing for every clinician.
The PEBA State Health Plan and Companion Benefit Alternatives
The South Carolina Public Employee Benefit Authority provides the State Health Plan to state agencies, school districts, colleges, and many local governments, so many South Carolina therapists see its members every week. BlueCross BlueShield of South Carolina is the plan’s third-party administrator, but behavioral health is managed by Companion Benefit Alternatives, and some behavioral health services require prior authorization from CBA. The plan does not cap the number of medically necessary behavioral health visits. Knowing that CBA, not the medical side of the plan, manages the behavioral health benefit prevents many State Health Plan denials.
Commercial Insurance in South Carolina
BlueCross BlueShield of South Carolina and its HMO affiliate, BlueChoice HealthPlan, cover a large share of the commercial market. Most practices also bill Aetna, Cigna, and UnitedHealthcare, and individual-market members often carry Ambetter from Absolute Total Care. Many large Upstate and Lowcountry employers self-fund their plans, which puts them under federal ERISA rules instead of the state prompt pay law. Our insurance verification services identify the plan type and the behavioral health administrator before the first visit.
Telehealth Without a State Mandate
South Carolina has no law requiring private insurers to cover telehealth or to pay for it at in-person rates. A video session may be covered at full rate by one plan, at a reduced rate by another, and not at all by a third. Healthy Connections Medicaid covers telehealth, and for established patients it allows certain audio-only codes when video is not available. We check every commercial plan’s telehealth policy before virtual sessions are billed. Practices near Charlotte, Augusta, and Savannah should also confirm the client was physically in South Carolina during the session.
License Types in South Carolina
The Department of Labor, Licensing and Regulation oversees the boards that license behavioral health clinicians. Counselors and marriage and family therapists start as LPC Associates or LMFT Associates, practicing under an approved supervision plan, and then earn the full LPC or LMFT. Clinical social workers hold the LISW-CP, Licensed Independent Social Worker, Clinical Practice, which is distinct from the LISW-AP for advanced non-clinical practice and from the LMSW. Payers credential associates and LMSWs inconsistently, and a claim with the wrong credential will deny. We confirm each payer’s rules for every license level.
Medicare and TRICARE in South Carolina
Palmetto GBA is the Medicare Administrative Contractor for South Carolina under Jurisdiction M, and it is headquartered in Columbia. LPCs and LMFTs can enroll in Medicare as of January 1, 2024. South Carolina’s military installations, including Fort Jackson, Joint Base Charleston, Shaw Air Force Base, Marine Corps Air Station Beaufort, and Marine Corps Recruit Depot Parris Island, make TRICARE East a meaningful part of many practices’ caseloads.
Credentialing a South Carolina Practice
A South Carolina group may need SCDHHS enrollment, contracts with each Healthy Connections MCO, BlueCross BlueShield of South Carolina and BlueChoice, network participation for State Health Plan members, Aetna, Cigna, UnitedHealthcare, TRICARE, and Medicare, for every clinician, with changes filed whenever an associate is upgraded. Until a contract’s effective date, sessions are handled as out of network. We handle every application and CAQH profile and follow each one to approval. The behavioral health credentialing page has the details. For the Medicaid side, see our South Carolina Medicaid provider enrollment guide.
Denials We See in South Carolina
- A State Health Plan service without CBA authorization. Some behavioral health services require it.
- The wrong Medicaid plan. The client switched MCOs or moved into managed care in 2026.
- A missing SCDHHS enrollment. MCO credentialing depends on it.
- A commercial plan that does not cover telehealth. There is no state mandate to fall back on.
- An associate billed to a payer that will not credential them. This applies to LPC Associates, LMFT Associates, and LMSWs.
- A recoupment without proper notice. Take-backs that skip the 30-business-day notice or pass the 18-month limit can be challenged.
For a backlog of unpaid or denied claims, see our claims denial management service.
Across South Carolina
Columbia practices see many State Health Plan members from state government and the university, along with Fort Jackson families. Charleston practices add Joint Base Charleston TRICARE volume and a busy commercial market. Greenville and Spartanburg practices serve large self-funded employers and clients who work or live across the North Carolina line. Rock Hill and Fort Mill sit inside the Charlotte metro, so North Carolina plans are common there. Beaufort and Hilton Head practices bill TRICARE for Marine Corps families, and Myrtle Beach practices often see North Carolina residents. Your setup is built around the plans your part of the state brings in.
