Does the NPI replace the tax ID number?

The billing provider’s tax ID number and NPI are always required on claims. Any other providers identified on the claim, such as rendering provider or service facility, must be identified with their NPI only. Their tax ID number should not be included. For eligibility, claim status inquiry, referral and precertification, only the NPI (no tax ID number) is used. However, we must have been informed of the provider’s NPI, and it must have been loaded into our provider database.
