Provider Communications


Resource for WHA Providers

WHA developed the Clinical Provider Handbook as a comprehensive resource for our clinical providers and their staff to have access to our policies, procedures, and standards in patient (member) care, as well as important contacts, tools, and processes for communications with WHA, and the ongoing delivery of health care services to our members.

WHA mails this resource annually to contracted clinical providers. You can also download the handbook or request copies from WHA’s Provider Relations at 844.870.2178 or
