Should I share my NPI with anyone?

Yes. Like UPIN numbers that were used prior to the establishment of the NPI, other physicians and providers to whom you refer will need your NPI number in order to submit claims for services for patients you refer to them.

If another party does billing on your behalf, that party will need your NPI.

You may also need NPI numbers from hospice and home health agencies and other physicians in order to bill for your services.
