Summary
HealthNet California is requiring all providers to update and certify their information in CMS's National Plan & Provider Enumeration System (NPPES) database, which will be used as the primary source for provider directories instead of frequent phone calls to offices.
Action Required
Within 60 days: All providers must log into NPPES and update their information including provider name, mailing address, telephone and fax numbers, specialty, and all active practice locations where patients can schedule appointments. Remove any inactive practice locations. After updating, providers must certify the accuracy of all information in NPPES. Contact Provider Services Center at 800-929-9224 with questions.
