Long drawn out procedure. You can sometimes find carrier directives as to how they want this info supplied by going to their portals and looking up this information. Yes, another administrative burden in keeping up with all the portals and password administration. Also, I read something in this month's Healthcare Monthly magazine by making sure the NPI's are updated too, depending on how long it may have been since they did that. Even after a year of updates, we still had some carriers that had not updated the information we supplied within their own systems, which caused additional grief. But if you get started early enough, and have a systematic plan of accomplishing your purpose( starting with your major payers), your issues may be less problematic.
