Planning guidance only—not a guarantee. Requirements, network capacity, contracting, and payer review can affect timing and effective dates.
Community Health Plan of Washington (CHPW) is a Washington-based health plan with Apple Health (Medicaid), Medicare Advantage, and Individual & Family Cascade Select offerings. New sole proprietors and group practices can start a contract request through CHPW’s Provider Enrollment Form.
For providers seeking to serve CHPW Apple Health members, CHPW says that both the group and individual provider NPIs must be registered and active with the Washington State Health Care Authority. HCA enrollment and a CHPW network agreement are separate steps; do not assume one establishes the other.
CHPW states that it will contact applicants about a new contract request in 45–60 days, while some providers and practices may take up to 90 days. That timing is for CHPW’s response to the request, not a guarantee of participation or an effective date. Product availability, service area, provider type, and the completed review can affect the outcome. Existing CHPW practices should use the plan’s change forms and tools for roster or network-status updates.
