National Provider Identifier

​The National Provider Identifier (NPI) is a Health Insurance Portability and Accountability Act (HIPAA) administrative simplification standard. Each NPI is a unique identification number for covered health care providers. Covered health care providers, all health plans and health care clearinghouses will use NPIs in the administrative and financial transactions adopted under HIPAA. The NPI is a random 10-digit number with no user identifying information.

Getting Your NPI

Providers who have not yet applied to FOX Systems for an NPI should do so as soon as possible.

Note: Providers who do not already have a taxonomy, may refer to the Washington Publishing Company for assistance.

Healthcare providers can apply for NPIs three ways:

  • For the most efficient application processing and the fastest receipt of NPIs, log onto the National Plan and Provider Enumeration System and apply online.
  • Healthcare providers can agree to have an Electronic File Interchange organization (EFIO) submit application data on their behalf (i.e., through a bulk enumeration process) if an EFIO requests permission to do so.
  • Healthcare providers may download a copy of the paper NPI Application/Update Form (CMS-10114) and mail the completed, signed application to:
    NPI Enumerator
    P.O. Box 6059
    Fargo, ND 58108-6059

Sharing Your NPI

Once providers obtain NPI and taxonomy code(s), FOX Systems will issue verification. To submit your NPI and taxonomy code(s) to Provider Enrollment by mail to:

Kentucky Medicaid Provider Enrollment
P.O. Box 2110
Frankfort, KY 40602

Providers, if you have additional questions about filing and sharing your NPI with Kentucky Medicaid, please see the list of Frequently Asked Questions about registration.

Using Your NPI

Providers who have registered their NPI and taxonomy(s) with Kentucky Medicaid should start billing both the correct NPI and taxonomy on the claim effective for any dates of service on or after the day they were notified by Kentucky Medicaid that their NPI and taxonomy(s) were registered.

In addition, providers who have one NPI and multiple provider IDs should note that Kentucky Medicaid strongly encourages and suggests providers bill the appropriate taxonomy with the NPI in order to uniquely identify themselves.
