What is an NPI Number?
The National Provider Identifier (NPI) is a unique 10-digit identification number issued to healthcare providers in the United States by the Centers for Medicare and Medicaid Services (CMS). The NPI is used for identification purposes in standard healthcare transactions.
Type 1 NPI (Individual)
Assigned to individual healthcare providers such as physicians, nurses, dentists, chiropractors, physical therapists, pharmacists, and other practitioners. Each individual can only have one NPI.
Type 2 NPI (Organization)
Assigned to healthcare organizations such as hospitals, group practices, nursing homes, clinics, laboratories, pharmacies, and medical equipment companies. Organizations can have multiple NPIs.
Why NPI Numbers Matter
HIPAA Compliance
The Health Insurance Portability and Accountability Act (HIPAA) requires covered entities to use NPI numbers in all standard electronic healthcare transactions, replacing legacy identifiers like UPIN.
Claims Processing
Insurance companies and Medicare/Medicaid use NPI numbers to identify providers on medical claims, ensuring accurate reimbursement and reducing administrative errors.
Provider Verification
NPI lookup allows patients, employers, and other providers to verify a healthcare provider's credentials, specialty, and practice location information.
