What is a npi number?

An NPI (National Provider Identifier) is a 10-digit numeric identifier assigned to health care providers in the United States. It is used to identify a provider's identity, location, and other relevant information. NPIs are required for all providers who submit claims to Medicare, Medicaid, and other federal health insurance programs. They are also used by private health insurers and certain other entities.

NPIs are issued by the National Plan and Provider Enumeration System (NPPES), which is a centralized system for collecting and disseminating information about health care providers. NPPES is operated by the Centers for Medicare & Medicaid Services (CMS), which is a federal agency that administers Medicare and Medicaid.

To obtain an NPI, a health care provider must submit an application to NPPES. The application process involves providing information such as the provider's name, address, and specialty. Once an application is approved, the provider will be issued an NPI.

NPIs are used for a variety of purposes, including:

* Identifying providers on health insurance claims forms

* Verifying the accuracy of provider information

* Preventing fraud and abuse in the health care system

* Conducting research on health care providers and their services

NPIs are important tools for ensuring that the health care system operates efficiently and effectively. They help to ensure that providers are properly identified and that their information is accurate. NPIs also help to prevent fraud and abuse in the health care system.
