Regence and MultiCare signed a new provider network agreement on June 2. MultiCare providers in Grays Harbor, Thurston, and Yakima counties are again in network for UMP members. Additionally, services members received since May 10, 2026, will be treated as in-network as if no interruption in network status occurred. MultiCare providers in other counties also remain in network.

Regence will mail a follow-up letter to members indicating the new agreement is in effect. However, some members are still receiving undated letters from MultiCare that state no agreement exists – such letters were mailed before the parties reached a new agreement on June 2.
