Does IBC require different NPIs when there are currently different provider numbers?
While keeping NPI enumeration requirements in mind, IBC strongly encourages providers to enumerate with NPIs in the same configuration in which they are now enumerated with IBC using corporate provider IDs. Otherwise, issues may occur with your claim payments and internal business and reporting procedures. IBC recommends that you take a close look at your current provider number configuration and plan wisely when obtaining your NPI(s).
