Why is my NPI data (personal information) being displayed publicly?
If you have an active NPI profile, your profile is required to be disclosed according to the FOIA and eFOIA. HIPAA also requires covered providers to share their NPI with other providers, health plans, clearinghouses and any entity that may need it for billing purposes.

How do I correct or change the NPI data displayed here?
At any time, providers can make changes to their NPI profile at NPPES. Login to NPPES to make changes online or call (800) 465-3203 for assistance. Changes made at NPPES will be reflected on this web site within a few days.

Can I hide my NPI profile from the public?
