Montana prompt pay law dental

Sourced answer

Under Mont. Code Ann. §33-18-232; §33-18-231; §33-18-233, the Montana payment deadline is 30 days (no format split). A non-compliant insurer liable on the claim owes the claim plus 10% annual interest from the date the claim was due (day 30, or day 60 after an information request) — but only when the computed interest exceeds $5 (§33-18-232(2)). Dental applicability: Dental reach is entity-dependent, and only one of the three answers is settled. 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.
