Washington Credentialing Standardization Group (WCSG)

The WCSG is a group comprised of credentialing representatives from Hospitals, Health Plans, and other physician organizations. While the WCSG is not a committee of WAMSS, they are a committee that works closely with WAMSS to identify opportunities to streamline the credentialing process. Participation in WCSG is voluntary, is free of charge, and is not dependant on membership with WAMSS. Below are some standardized tools that the WCSG has developed over the years that are accepted by most organizations around the state. Interested in WCSG meeting information?  Contact the WCSG Chair  for the upcoming meeting information and agenda.

The Washington Practitioner Application (WPA) is a standardized application that is accepted by most hospitals, health plans, and physician organizations through the state. See some changes that need to be made to the application? We update the application on even years (2012, 2014, etc.), so submit your change request to the WCSG Chair  and we’ll add it to the list of revisions to consider.

WPA 2015 (Word) Reappointment Attestation



A Release of Information is a vital component to credentialing applications. It allows credentialing departments to primary source verify information disclosed on the application, and holds them harmless for decisions they make as a result of receiving that information. Don’t write your own Release, use this one!

This Reappointment Attestation meets all CMS, DNC, NCQA, and URAC requirements for reappointment/recredentialing, and is accepted by most organizations throughout the state. Check ours out and see if you’d like to include it in your organization’s documents.

The WCSG also has a sub-committee that works to streamline delegation oversight audits. The WCSG Shared Audit Team is a group of 9 Health Plans and Physician Organizations across the State that collaborate on annual assessments of medical groups. The team maintains an audit tool (WCAT) and a file review worksheet (WFRW) that is compliant with NCQA, CMS, and State Medicaid requirements for credentialing. Want to complete an internal audit of your credentialing files and policies, but don’t have any tools?  Use ours! Tools are updated bi-annually in January and July, or more frequently as needed.
