Summary
Effective September 1, 2021, Indiana Health Coverage Programs (IHCP/Medicaid) revised NPI reporting requirements to ensure alignment between organizational structure, legal name, taxpayer ID, and NPI type on enrollment applications. Providers must use Type 1 NPI for individual practitioners and Type 2 NPI for organizations, with existing enrolled providers required to bring their enrollments into compliance.
Action Required
Immediately: All providers enrolled with Indiana Medicaid must review their current enrollment to ensure NPI type matches their organizational structure. Individual practitioners conducting business under personal names must use Type 1 NPI with SSN, while those using business names or organizations must use Type 2 NPI with EIN. Contact IHCP Customer Assistance at 800-457-4584 if enrollment corrections are needed to maintain compliance and avoid potential billing issues.
