National Provider Identifier

Use of NPI is Now Mandatory

Beginning May 17, 2008 Humana will move into compliance with the NPI mandate and must begin to enforce use of NPI only on HIPAA standard transactions. HIPAA electronic transactions included under the mandate will require use of an NPI. Provider claims (HIPAA 837 I, P & D) must contain an NPI, or they will be rejected by the clearinghouses Humana has contracted with.

Providers are strongly encouraged to obtain an NPI if they have not already done so and to begin using their NPI on all electronically submitted claims prior to the mandate date to avoid disruption in cash flow. Please ensure that your practice management system or billing service has your NPI(s) implemented for use on electronic claims.

For providers receiving the Electronic Remittance Advice (HIPAA 835 ERA), Humana will begin including the NPI with the ERA data once Humana has received the NPI on claims submitted. In the spirit of administrative simplification, and in conjunction with CMS recommendations, providers submitting paper claims are also encouraged to use their NPI.
