OK.... my medical psychologist received information and I think it is incorrect. The discription of 90804 is individual psychotherapy 20-30 minutes. He was told that if he sees a pt. for even 15 or 17 minutes,,,,that he can use this code. Is this true? I am a licensed coder and have always went by the "book" especially going by the descriptions of every code used. If this is infact true, where can I get back up information on this in case of future audits? Common sense tells me NO. If it were true, discriptions would not be needed. Would this be considered up charging? Please help!
