Health Care Authority Provider Revalidation – Watch for Notices

March 27, 2019

The Health Care Authority (HCA) recently contacted WSHA regarding the federally required revalidation process. Hospitals and providers that do not complete revalidation face deactivation of their Medicaid core provider agreement and disruption to payment. WSHA recently contacted some hospitals that according to HCA had not yet responded to revalidation notices and were in danger of deactivation.

Hospitals and providers must complete revalidation for each National Practitioner Identification (NPI) number associated with their facility or group within five years of its previous revalidation. Revalidation involves completion and upload of an updated core provider agreement, debarment statement, IRS W9 form, and additional documents, depending on the type of facility or provider. The revalidation page and instructions are at

HCA advised WSHA that ProviderOne does not have the capability for facilities and providers to look up their revalidation date. Facilities and providers can contact HCA Provider Enrollment at or by calling 1-800-562-3022 Extension 16137 if they believe they may be due revalidation but have not received a notice, or if they have questions regarding the process.
