South Carolina prompt-pay law for dental claims

South Carolina's prompt-pay chapter does not reach standalone dental insurance. The deadlines and interest below apply only to dental inside a comprehensive medical plan.

S.C. Code §38-59-230; §38-59-240 (rate via §34-31-20(A))

Payment deadlines

Electronic claims
20 business days (electronic)
Paper claims
40 business days (paper)

South Carolina counts in business days, and the clock starts later than most: payment is due within 20 business days (electronic) or 40 business days (paper) following the later of the insurer's receipt of the claim or the date it has all the information needed for the claim to be a clean claim. "Clean claim" is heavily conditioned — received within 120 business days of the date of service, on a standard CMS 1500 or UB 04 form or a HIPAA-standard electronic format, primary payor established, no material defect, complete documentation and coding, and premiums timely paid. Defects that keep a claim out of adjudication must be noticed to the provider inside the same 20 or 40 business-day windows.

Interest and penalties

Where payment is late the insurer owes interest at the §34-31-20(A) rate on the balance due, computed from the twenty-first or forty-first business day, as appropriate, to the date the insurer directs issuance of the check or the electronic funds transfer (§38-59-240(A)). That cross-reference is to the legal rate of interest — 8.75 percent per annum — not to the judgment rate in subsection (B). No interest is owed on duplicates submitted mid-adjudication, to providers who balance-bill in breach of contract, during force majeure, or where payment was made to the plan member, and the insurer may remit interest quarterly in a separate check. The article expressly creates no private right of action; the Department of Insurance enforces it.

Does it apply to dental? Standalone dental excluded

Separately offered dental plans sit outside the article. Its "insurer" definition reaches an insurance company, a health maintenance organization, and any other entity providing "health insurance coverage, as defined in Section 38-71-670(6)" — and that definition excepts, when offered separately, "limited scope dental or vision benefits." Dental benefits embedded in a medical plan are inside the 20/40 business-day rule; a claim to a stand-alone dental carrier is not covered by it. The article also does not reach national account delivery program claims the insurer does not solely process, or state and federal government program claims other than as employer (§38-59-260).

Self-funded (ERISA) plans: A self-funded private-employer (ERISA) dental plan is generally beyond a state prompt-pay statute's reach: 29 U.S.C. § 1144(b)(2)(B) bars a state from deeming such a plan an insurer, and the courts have read that to keep state insurance regulation off it. The statute itself never uses the words self-funded or prompt pay, and the rule is not categorical — a self-funded governmental or church plan is not an ERISA plan at all, so state law can reach it; § 1144(b)(6) leaves multiple employer welfare arrangements open to state insurance law; and nothing in § 1144 addresses state enforcement against the third-party administrator or the network contract. Where the plan is a self-funded ERISA group health plan, the federal claims-procedure deadlines apply instead: a post-service benefit determination within 30 days (one 15-day extension), at least 180 days to appeal, and an appeal decision within 60 days (or two 30-day levels), under 29 CFR 2560.503-1.

No standalone dental calculation

This state regime excludes standalone dental plans, so this page does not calculate a statutory dental late-payment amount. Check the plan contract and any other law that actually governs the claim before asserting interest.

Also in the statute

  • Clearinghouses may not convert an electronic claim to paper (§38-59-230(D)).
  • Overpayment recoupment requires 30 business days' written notice and is limited to an 18-month lookback, with exceptions for fraud, self-insured plans, and government programs (§38-59-250).
  • Article 2 was enacted by 2008 Act No. 356, effective one year after approval on June 11, 2008.
