Relating to mediation and arbitration between health benefit plan issuers or administrators and out-of-network health care providers.

HB 3366 requires health benefit plan issuers and out-of-network healthcare providers to resolve payment disputes through mandatory mediation, with mediators able to order binding arbitration if parties fail to cooperate in good faith. Both parties must split arbitration costs evenly, and the law prohibits providers from filing lawsuits once arbitration is initiated under this process. The new rules apply only to medical services provided on or after January 1, 2026, with prior disputes governed by existing law. This creates a structured pathway to avoid litigation while ensuring mediators have authority to bind insurers to payment agreements.
