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

Under K.S.A. 40-2442; 40-2441, the Kansas payment deadline is 30 days (no format split). An insurer that fails to comply must pay interest at 1 percent per month on the amount of the claim remaining unpaid 30 days after receipt, and that interest "shall be included in any late reimbursement without requiring the person who filed the original claim to make any additional claim for such interest" (K.S.A. 40-2442(b)). Dental applicability: Expressly covered — Kansas names dental in the definition itself. 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.

Kansas prompt-pay law for dental claims

Kansas's prompt-pay law covers dental claims. Clean claims must be paid or denied within 30 days; late payment accrues statutory interest.

K.S.A. 40-2442; 40-2441

Read the statute text

Payment deadlines

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

Within 30 days after receipt of any claim, the insurer must either pay a clean claim or send a written or electronic notice acknowledging receipt and stating the claim's status — either refusing to reimburse all or part of it and specifying each reason, or explaining that additional information is necessary. When more information is requested, the provider has 30 days to supply it and the insurer then has 15 days after receiving everything to pay or deny, on the same interest terms.

Interest and penalties

An insurer that fails to comply must pay interest at 1 percent per month on the amount of the claim remaining unpaid 30 days after receipt, and that interest "shall be included in any late reimbursement without requiring the person who filed the original claim to make any additional claim for such interest" (K.S.A. 40-2442(b)). The duty is conditional, not absolute: a timely denial or information-request notice satisfies subsection (a), and subsection (e) excepts good-faith disputes over the claim's legitimacy and claims with a reasonable basis to suspect fraud. Violations committed with flagrant and conscious disregard, or with enough frequency to constitute a general business practice, are unfair trade practices under K.S.A. 40-2401 et seq.

Does it apply to dental? Dental expressly covered

Expressly covered — Kansas names dental in the definition itself. A "policy of accident and sickness insurance" means any policy or contract insuring against loss resulting from sickness, bodily injury, or accidental death, including "any hospital, dental or medical expense policy" (K.S.A. 40-2441(c)). The instructive contrast in the same definition: stand-alone vision-care-only coverage is excluded while dental-expense policies are in. Payors reach beyond insurers to health maintenance organizations, third-party administrators, and any other entity that pays claims under such a policy.

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.

Estimated interest

$12.75

1%/mo (monthly tiers, prorated by days)

1% per month on the amount left unpaid 30 days after receipt, included in the late reimbursement without the provider claiming it. Interest is conditional: a timely denial or information-request notice stops it, and good-faith disputes over a claim's legitimacy or a reasonable basis to suspect fraud are excepted.

How we calculate this

Formula: claim × monthly tier rate × days in tier ÷ 30, summed across tiers, using simple (not compounded) interest as the statute states it. The rate and deadline come from K.S.A. 40-2442; 40-2441, 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

Recoupment of an erroneous payment must be initiated within 18 months after the end of the month in which the payment was made; fraud extends that window to the K.S.A. 60-513 limitation period rather than removing it (K.S.A. 40-2442(f)).
Other excluded product types include reinsurance, life and annuity, credit-only, disability income, long-term care, Medicare supplement, drug-only, vision-care-only, workers' compensation, and auto medical payments.
The statute says nothing about network status; the duty attaches to "any claim."
