ProviderOne for social services

About this page

This webpage is for social service providers who are contracted with the Washington State Department of Social and Health Services (DSHS) or a local Area Agency on Aging (AAA) and who receive Medicaid payments via ProviderOne for authorized social services provided to Medicaid-eligible clients.

Examples of social service providers include, but aren’t limited to:

• Adult family homes
• Assisted living facilities
• Home care agencies
• Home delivered meals
• Private duty nurses
• Personal emergency response system vendors

If this describes you or your organization and your clients’ services are authorized via a social services authorization in ProviderOne, this webpage is for you!

If you are an individual provider or caregiver providing in-home care services and are employed by Consumer Direct Care Network Washington (CDWA) or a Home Care Agency, this page is not for you since you do not submit claims directly to ProviderOne to receive payment. Contact either CDWA or the Home Care Agency you are employed with for questions about logging your hours and receiving payment for services. To verify IP wages paid by DSHS through IPOne prior to May 2022, see For social services providers’ contact list.
