When is the inbox closing?
No new messages will be accepted by the Provider Enrollment inbox after December 31, 2025. Provider Enrollment will continue to respond to open requests until they are resolved. Messages will be retained in accordance with the Washington State Record Retention Schedule.
Note: Social Services Providers may still contact Provider Enrollment via phone at 1-800-562-3022, ext. 16137 on Tuesdays & Thursdays and may contact HCA's Medical Assistance Customer Service Center (MACSC) Monday-Friday for assistance related to claiming, payments, and general ProviderOne questions/issues.
ProviderOne issue fixed: Signing up for EFT
Over the past few months, some providers encountered issues when trying to sign up for electronic funds transfer-EFT (Direct Deposit) in ProviderOne. The system would show the EFT status as 'Failed' when it should have been 'In-Process'. As of 12/5/2025 the Health Care Authority (HCA) has resolved this issue and the system should now be working properly. If you experienced issues with signing up for EFT over the past few months, please login to your ProviderOne account and attempt to sign up for EFT again. If you continue to encounter issues, please contact HCA's Office of Provider Enrollment via phone at 1-800-562-3022 ext. 16137 (phones open Tues & Thurs) or online.
