Welcome to the Kaiser Permanente Washington Provider Site

This site is your source for all the information you need to do business with Kaiser Permanente and to care for our members.

This site contains our most current policies and procedures, and latest news.

Most of the information on the site is accessible to all users without having to sign on. You need to create an account with OneHealthPort to access the secure sections of our site.

The Provider Manual

All of the information in the Provider Manual and more is available on this site. We have organized the site around these major topic areas:

  • Billing and Claims
  • Referrals and Clinical Review
  • Coverage and Eligibility
  • Patient Care
  • Working With Us

All pages containing contractually binding information are clearly labeled at the top with "From the Provider Manual." When your contract with Kaiser Permanente refers to the Provider Manual, it refers to these pages. For a listing of all of the contractually binding information, see the Provider Manual.

Online Business Tools

Sign on to access most of our online business transaction tools. Use these tools to check members' eligibility and benefits, to submit preservice authorization requests (referrals), and to check on the status of referral requests or claims.

We encourage all providers submit claims electronically via one of our many partners. OneHealthPort serves as a portal for eligibility queries, claims status queries, and referral and authorization submittals.

Without signing on, you can search our drug formularies.
