What is NPI (National Identifier Number)?
The Health Care Provider Taxonomy code is a unique alphanumeric code, ten characters in length. The code set is structured into three distinct “Levels” including Provider Grouping, Classification, and Area of Specialization.
The Health Care Provider Taxonomy code set is published (released) twice a year on July 1st and January 1st. The July publication is effective for use on October 1st and the January publication is effective for use on April 1st. The time between the publication release and the effective date is considered an implementation period to allow providers, payers, and vendors an opportunity to incorporate any changes into their systems.
Purpose of NPI?
It is a single unique identification number that is issued by the federal government to health care providers. It is intended to improve the efficiency of the health delivery system and help to reduce fraud and abuse.

Does the NPI replace the tax ID number on eligibility, claims status inquiry, referral, and precertification transactions?
For eligibility, referral, precertification transactions, federal regulations require submission for providers’ NPI number unless the provider is not considered a health care provider as defined under HIPAA.
For claim status inquiry, NPI is required in the servicing provider field, but the billing provider ID can be an NPI, Tax ID, or PIN/PVN
Are providers allowed to send other identification numbers such as PIN, PVN, and TIN in electronic transactions?
To be compliant with the regulations, covered entities must use the NPI of any health care provider that has been assigned an NPI to identify that health care provider in HIPAA standard transactions. The use of other IDS is permitted only to identify an entity or individual as a taxpayer.
Other identification numbers may be used in certain situations:
- Non covered health care providers
- Providers acting in another role, such as information submitter or receiver or as a utilization management organization.
- Nonmedical living arrangements.
- Nonemergency transportation providers.
- Independent practice associations (IPAs).
