What is the Idaho prompt-pay deadline for dental claims, and what interest applies to late payment?

Idaho prompt-pay law for dental claims

Idaho's prompt-pay statute never names dental, and its definitions do not settle whether it reaches a stand-alone dental carrier. The deadlines are below.

Idaho Code §§41-5602, 41-5603, 41-5605

Read the statute text

Payment deadlines

Electronic claims: 30 days (electronic, if filed within 30 days of service)
Paper claims: 45 days (paper, if filed within 45 days of service)

Idaho's deadlines carry a submission precondition that most summaries drop. If the claim is submitted electronically within 30 days of the date service was delivered, the insurer must pay or deny it within 30 days of receipt; a paper claim submitted within 45 days of service must be paid or denied within 45 days of receipt. A denial for missing information must specifically describe all information and supporting documentation needed to evaluate the claim. The deadlines also yield to contract: an insurer complying with a provider contract that specifies different payment requirements is not required to meet them (§41-5605(3)), so for a contracted dentist the PPO agreement may control the timing.

Interest and penalties

Section 41-5603 requires interest "at the contract statutory rate pursuant to section 28-22-104, Idaho Code, on the unpaid amount of a claim that is determined to be due and owing," accruing from the date payment was due until the claim is paid. Because §28-22-104 carries both a 12 percent legal rate and a distinct judgment-rate formula, and the prompt-pay chapter does not say which governs, the honest citation is to the section rather than to a single percentage. Interest amounting to less than $4.00 need not be paid.

Does it apply to dental? Dental scope unsettled

The word "dental" appears nowhere in Idaho's prompt-payment chapter — not in the exclusions, and not in the affirmative definition either. "Insurer" is defined as any insurer that sells hospital, medical, long-term care, or vision insurance policies or certificates, plus managed care organizations (§41-5601(6)). A stand-alone dental carrier is therefore arguably outside the chapter, while dental services paid under a medical or managed-care policy are inside it. There is no controlling source resolving the question, so this page states it as open rather than picking a side.

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.

Because this statute never names dental, whether it reaches your claim is unresolved. Treat anything below as the figure the statute would produce if it applies — read the applicability note above first.

How the claim was submitted

Idaho sets a different deadline for each, so this decides which day the field below counts from.

No published rate to apply

Idaho points to an external rate rather than setting one: §41-5603 requires interest "at the contract statutory rate pursuant to section 28-22-104," and that section contains both a 12% legal rate (absent a written contract) and a separate judgment-rate formula. Which sub-rate applies is not spelled out, so this page cites the section rather than computing a number. Interest under $4.00 need not be paid, and insurers may roll interest into a later payment.

How we calculate this

The calculator does not show a payable amount for this result; the explanation above states the controlling limitation. The rate and deadline come from Idaho Code §§41-5602, 41-5603, 41-5605, read against the statute text linked in the sources on this page (last verified 2026-08-30). Accrual start dates, clean-claim status, safe harbors, and plan funding all affect the real figure — treat this as an estimate for the payer conversation, not a demandable amount.

Also in the statute

Provider contracts specifying different payment requirements displace the statutory deadlines (§41-5605(3)); other exceptions cover suspected fraud, records needed for subrogation or coordination of benefits, unpaid premium, and force majeure.
Enforcement is deliberately light: the director may impose an administrative fine of up to $5,000, the chapter creates no private cause of action, and a 95% annual clean-claims safe harbor blocks penalties (§41-5606).
Amendment history is thin — §41-5602 has been amended twice since 2004 (2005 and 2025), and the definitions section has never been amended.
