MA H1267

Prohibits health insurance carriers from including provisions in contracts with health care providers that allow termination without cause, and requires carriers to provide written reasons for any involuntary provider disenrollment

Bans carriers from making unilateral changes to material contract terms—including fee schedules, payment terms, covered services definitions, utilization review policies, credentialing, and quality management procedures—unless required by law

Allows unilateral changes only if the effective date falls after the current contract term ends and the provider receives written notice more than 90 days before the provider's termination/non-renewal deadline

Requires the Group Insurance Commission to refuse to purchase health insurance policies from insurers whose provider contracts contain prohibited termination-without-cause or unilateral change provisions

Preserves the right of carriers and providers to enter into mutually agreed-upon contract amendments
