Established in 2013, Rainier Health Network was Washington state’s second ACO and the first in the South Puget Sound area, with a vision to become the premier network in the region. The network primarily serves King, Pierce and Kitsap counties, managing more than 230,000 lives with over 5,000 providers.

Today, Rainier Health Network has evolved beyond the CMS Medicare Shared Savings Program to include all types of health plans from commercial payers to employer-direct. We have also expanded our provider membership to ensure a comprehensive network across our geography.

Quality Highlight

Four standing committees on Rainier’s board manage the development of system improvements to help the ACO reach its goals. In 2015, the network earned its first MSSP payout of nearly $3 million with a Quality Composite Score of 87%. With continuous improvements, RHN in 2019 received an outstanding quality score of 95% and earned over $6.7 million in Medicare Shared Savings.
