Our office is using "incident-to" billing for MD + 2 old NPs. We hired a new NP and her provider numbers are pending. Can she see patients on her own and have him sign her charts without him going into the rooms and seeing patients after her? Can we bill her visits under his Provider NPI number like we do with our other 2 old NPs? To clarify: she is not seeing any new pts or any established pts with new problems. She is only seeing well established patients while the physician is readily available should she have any questions. We want to make sure we are being 100% compliant in this process.
