An Act relative to unilateral contract changes

This bill prohibits health insurance carriers from including "termination without cause" clauses or unilateral changes to material contract terms (such as payment rates, service definitions, or quality policies) with healthcare providers. It requires carriers to provide written notice of any change at least 90 days before the provider must respond, and limits such changes to occur only after a contract's current term ends. The law specifically applies to state health insurance purchasing entities (like MassHealth) and their contracts with providers. It allows mutually agreed amendments but bans unilateral modifications except as required by law.
