Dentovio is an independent publisher, not a law firm, insurance department, or government agency. This page was drafted with AI assistance and read against the primary sources linked here, with a per-claim verification record — quote, statutory pinpoint, and the URL actually opened — behind every deadline, rate, and applicability verdict in all fifty-one jurisdictions. It has not been reviewed by a credentialed attorney or dental billing specialist. These pages summarize state prompt-pay statutes as read against the official sources on the date shown, focusing on how each statute treats dental claims. Statutes change and their application turns on plan type, contract status, and claim facts. Educational reference only — not legal advice; confirm current law with the state insurance department or a licensed attorney before acting on a specific claim.

## Direct answer

Vermont's prompt-pay chapter (18 V.S.A. §9418) does not reach standalone dental insurance at all — Vermont exempts stand-alone dental outright: "The provisions of this section shall not apply to stand-alone dental plans licensed to do business in Vermont" (§9418(m)), and §9418(a)(3) excludes stand-alone dental plans from the definition of contracting entity. A Vermont dentist billing a stand-alone dental carrier has no §9418 deadline and no §9418 interest — the contract governs. Dental services paid under a medical health plan are inside the section. The broad "health care services" definition that includes dental, at 18 V.S.A. §9408a, is expressly scoped to that section, which governs uniform provider credentialing, not claim payment. Where the chapter does apply (dental inside a comprehensive medical plan), the deadline is 30 days (no format split). 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.

## Payment deadlines

- Electronic claims: 30 days (no format split)
- Paper claims: 30 days (no format split)

Not later than 30 days following receipt of a claim, a health plan, contracting entity, or payer must pay or reimburse it, or notify the claimant in writing that the claim is contested or denied with the specific reasons (§9418(b)). A third option covers claims pended during months two and three of the federal premium-tax-credit grace period. On a contested claim the clock restarts: 30 days after the plan receives the requested additional information. The timelines and the interest trigger both yield to the provider contract — subsection (g) applies them "from the day following the contract payment period, unless otherwise specified in the contract."

## Interest and penalties on late payment

"Interest shall accrue on a claim at the rate of 12 percent per annum" (§9418(e)), with the default accrual start being the first calendar day after the 30-day period following receipt, and subsection (g) applying the notice and interest duties from the day following the contract payment period unless the contract specifies otherwise. The Commissioner may suspend interest accrual for a major disaster, an act of God, a major computer-system failure, or to protect plan solvency. None of that reaches a claim to a stand-alone dental plan — see the applicability note.

## Does it apply to dental? Standalone dental excluded

Vermont exempts stand-alone dental outright: "The provisions of this section shall not apply to stand-alone dental plans licensed to do business in Vermont" (§9418(m)), and §9418(a)(3) excludes stand-alone dental plans from the definition of contracting entity. A Vermont dentist billing a stand-alone dental carrier has no §9418 deadline and no §9418 interest — the contract governs. Dental services paid under a medical health plan are inside the section. The broad "health care services" definition that includes dental, at 18 V.S.A. §9408a, is expressly scoped to that section, which governs uniform provider credentialing, not claim payment.

## 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.

## Also in the statute

- The duty runs to "a health plan, contracting entity, or payer"; health plan means a health insurer, disability insurer, health maintenance organization, medical or hospital service corporation, and — to the extent federal law permits — any administrator of an insured or self-insured plan (§9418(a)(8)).
- Vermont's Medicaid agency (DVHA) is not a contracting entity or payer for this section.
- A neighbouring section on downcoding and coding rules, 18 V.S.A. §9418a, has a revised version in force since January 1, 2026.
- Last amended by 2023, No. 6, §231, effective July 1, 2023. Vermont Statutes Online describes itself as an unofficial convenience copy of the annotated statutes.
