Prohibits certain requirements in insurance contracts

This bill prohibits insurers and health maintenance organizations from including specific restrictive clauses in contracts with healthcare providers. It bans requirements that force insurers to include all provider group members in networks, place them in the same network tier, include them in all products, block value-based benefit designs, impose "most-favored-nation" terms (except for rate negotiations), or restrict fee disclosure. The law directly affects insurers and healthcare providers negotiating contracts, preventing certain contractual terms from being enforced. The ban takes effect January 1, 2026, making any violating contract clause void while keeping other contract terms valid.
