We have a new arnp starting at our clinic this week. She is not credentialed with our office yet and probably will not be for several more months. I was told by my manager to use the modifer q6, and to list the supervising physican on insurance claims to get payment on the patients she will be seeing while we are waiting on her to get through credentialing. Everything i am reading online and just from reading the q6 modifier description, i do not feel this is legal billing? I am a very new coder so any advice on how or how not to use this modifier would be greatly appreciated. I am very concerned my certification could be on the line if i bill this way. I did what research i thought was necessary, but my manager asked me to get in touch with aapc memebers. Please help!
