ProviderOne login requirements

Per federal and state requirements, each person logging into ProviderOne must have their own login credentials (i.e., a unique user name and password). Generic or shared login credentials are not allowed. Each organization's ProviderOne System Administrator is responsible for setting up new user access. Find more information about setting up ProviderOne users and accessing ProviderOne in the Getting Started and Billing Essentials Guide. 

Attention: Home Care Agencies

Start & end times required on claims

Reminder, effective for dates of service on or after April 1, 2026, claims for in-home personal care services (T1019 with modifiers HQ, U2, U3, U4 & U6) and in-home respite care services (T1005 with no modifier & T1005 with modifier U2) submitted without the Service Start Time and Service End Time will deny. Service Start Time and Service End Time are required for compliance with federal Electronic Visit Verification (EVV) requirements.

We want to hear from you!

Over the past two years, DSHS and HCA have collaborated to create and update ProviderOne resources for Social Services Providers (e.g., billing guides, monthly newsletters, FAQs, etc.).

We want to ensure the resources available to you remain useful, user-friendly, and relevant. Please take this brief survey to let us know what's working, what isn't, and what other resources you would like to see.

Thank you for your input!
