You cannot report 90853 (Group psychotherapy [other than of a multiple-family group]) for the counseling that your clinician performed at the end with all the members of the family taking part in the session. You can only report 90853 when members of an active treatment group are taking part in the group psychotherapy session and not when members of the family of one patient are being counseled. In this case, this session too is part of the family therapy that is reported with an appropriate code from 90846 or 90847 depending on whether or not the patient was present.
Again, if the patient was present for the session with individual members of the family and for the group session, you cannot report it with two units of 90847. Also, if the patient was not at all present for the entire individual session or the group session, you cannot report two units of 90846.
If the patient was counseled individually and then not present during the group session with the rest of the family, you can report 90846 for the family psychotherapy without the patient present and a basic psychotherapy code, such as 90832 (Psychotherapy, 30 minutes with patient and/or family member), for the individual psychotherapy with the patient. Correct Coding Initiative (CCI) edits normally bundle the CPT® basic psychotherapy codes such as 90832 into 90846. However, as the modifier indicator for this edit is ‘1,’ you can unbundle the codes with the use of a modifier. You will have to report modifier 59 (Distinct procedural service) or XE (Separate encounter) with 90832 as it is the column 2 code in the edit bundle.
