WA| Washington’s Office of the Insurance Commissioner adopted rule R 2025-10 to implement SSB 5579 (RCW 48.43.732), December 23, 2025, establishing new requirements for how health carriers, health care providers, and facilities communicate about potential provider contract terminations to consumers. The rule bars these entities from making public statements about potential contract terminations until within 45 days of the contract’s termination date and directs the OIC to develop and publish standard template language for enrollee and patient termination notices by December 1, 2025, which must then be incorporated into all provider contracts by January 1, 2027. It also clarifies continuity of care protections, sets general standards and notice requirements for termination-related communications, and authorizes the OIC to enforce health-carrier-related provisions, including imposing civil monetary penalties for non‑compliance, effective January 23, 2026.
