NPI-1 and NPI-2
Do I need both?
A National Provider Identifier or NPI is a unique 10-digit identification number issued to health care providers in the United States by the Centers for Medicare and Medicaid Services (CMS).
This number identifies your license type, license level, and specialty. It is helpful when credentialing and billing for health related services.
Your license type could be as social worker, professional counselor, marriage and family therapist, etc. This also indicates whether you are licensed as a masters or doctoral level clinician.
Your license level would indicate whether you are provisionally, limited or fully licensed.
