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

Under Wis. Stat. §628.46 (claim classes via §646.31(2)), the Wisconsin payment deadline is 30 days (no format split). Overdue payments bear simple interest at 7.5 percent per year (§628.46(1)). Dental applicability: The section opens broadly — "Unless otherwise provided by law, an insurer shall promptly pay every insurance claim" — but subsection (3) limits it: "This section applies only to the classes of claims enumerated in s. 646.31 (2)." Those classes are residency-based, starting with the claim of a policyholder or insured who is a resident of Wisconsin, and extending to nonresident, property, third-party, assignee, beneficiary, and structured-settlement classes. A self-funded private-employer (ERISA) plan is generally beyond this statute's reach and runs on the federal claims-procedure clock instead — but that comes from the courts reading 29 U.S.C. § 1144, not from its text, and it is not categorical: a self-funded governmental or church plan is not an ERISA plan at all, § 1144(b)(6) leaves multiple employer welfare arrangements open to state insurance law, and nothing in § 1144 bars a state from reaching the third-party administrator or the network contract.

## Payment deadlines

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

"A claim shall be overdue if not paid within 30 days after the insurer is furnished written notice of the fact of a covered loss and of the amount of the loss" (§628.46(1)) — one unified standard with no electronic-versus-paper split. Subsection (2) adds the practical hedge: notwithstanding subsection (1), payment is not overdue until 30 days after the insurer receives the proof of loss required under the policy or equivalent evidence. Payment counts as made on the date a valid instrument was placed in the mail, properly addressed and postpaid, or otherwise on delivery.

## Interest and penalties on late payment

Overdue payments bear simple interest at 7.5 percent per year (§628.46(1)). The condition to watch is what makes a payment overdue: "any payment shall not be deemed overdue when the insurer has reasonable proof to establish that the insurer is not responsible for the payment." A genuinely disputed claim backed by reasonable proof never becomes overdue, so interest never starts. The 12 percent figure in older references was superseded by 2017 Wis. Act 235.

## Does it apply to dental? Dental covered, with caveats

The section opens broadly — "Unless otherwise provided by law, an insurer shall promptly pay every insurance claim" — but subsection (3) limits it: "This section applies only to the classes of claims enumerated in s. 646.31 (2)." Those classes are residency-based, starting with the claim of a policyholder or insured who is a resident of Wisconsin, and extending to nonresident, property, third-party, assignee, beneficiary, and structured-settlement classes. Dental claims of Wisconsin-resident insureds and policyholders fall inside class (a), which is how dental is reached — state the scope that way rather than as "every claim, any insurer." A chiropractic-specific rule in subsection (2m) does not generalise to dentistry.

## 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.
