Historical Context: CHPW Network Growth Since 2021
CHPW's network expansion accelerated significantly after returning to Medicaid coverage in 2021. The plan added Pierce, Chelan, Douglas, Grant, and Okanogan counties to its service area, increasing total Medicaid coverage from 19 to 24 counties. This expansion brought in over 45,000 new Medicaid members within the first 12 months.
By 2024, CHPW had established partnerships with seven Kaiser Permanente sites, marking the first time Kaiser accepted CHPW Medicaid coverage across multiple regions. The relationship grew to include Seattle Children's Hospital for pediatric specialty care and Providence health systems for western Washington coverage.
"CHPW is committed to Washington's health, and our expanded network ensures members can access quality care close to home," stated a CHPW representative in 2026.
