One Health Port

Single Sign-On

The Single Sign-On offers healthcare professionals an easy and secure way to access the provider portals of major local health plans and hospitals as well as other valuable online services.

Health Information Exchange

Washington State’s Health Information Exchange (HIE) provides healthcare organizations a secure, low-cost means to share standardized messages with trading partners on a system-to-system basis.

Clinical Data Repository

The Clinical Data Repository (CDR) is designed to simplify access to clinical history and provide a longitudinal view of an individual's patient record. The CDR is now open for testing.

Pre-Service Directory

The Pre-Service Directory offers healthcare professionals quick access to an online directory of updated links and instructions for using Payer websites for pre-authorizations and admission notifications.


OneHealthPort operates the Provider Data Service as one element of its administrative simplification work for Washington state. It is a statewide solution for gathering all the information that health plans and hospitals request from providers in the course of credentialing.


The Administrative Simplification (AdminSimp) program makes it easier for providers and payers to do business together by helping both parties solve problems related to shared workflows and information exchange.
