The National Provider Identifier is a unique number used to identify healthcare providers. It is required for standard healthcare transactions such as medical claims, insurance billing, and prescriptions. The National Provider Identifier helps streamline communication across federal health programs and private payers.

Why the National Provider Identifier Matters?
The National Provider Identifier simplifies healthcare administration by replacing multiple provider numbers to search npi number. Medicare, Medicaid, and private insurers no longer need to issue separate identifiers. This reduces administrative burdens for providers and payers, saving time and effort.
Healthcare providers use the National Provider Identifier in claims, medical records, prescriptions, and benefit coordination. It also connects with program integrity files and internal systems that link proprietary identifiers. Every covered entity using federal health programs must comply with these requirements.
Accessing NPI Data
Physicians, healthcare providers, or organizations can access data through the CMS NPI Registry. The registry is part of the National Plan and Provider Enumeration System (NPPES). Only information allowed under the Freedom of Information Act (FOIA) is released publicly.

Electronic File Interchange (EFI)
Large organizations may use Electronic File Interchange to apply for multiple NPIs. The EFIO, or Electronic File Interchange Organization, submits applications for hundreds of providers at once. This method reduces both administrative and financial burdens across healthcare systems.

Taxonomy Codes in NPI Applications
Healthcare providers must report taxonomy codes when applying for a National Provider Identifier. These codes represent the provider’s specialty or subspecialty within healthcare practice. Applicants may enter both primary and secondary taxonomy codes for clarity.
For example, a family medicine physician specializing in adolescent medicine may enter two codes. The primary code for family medicine would be 207Q00000X, while the secondary code is 207QA0000X. These codes help accurately identify provider specialties in health plan transactions.
