Code groups are used to restrict which codes can be used on sessions for a student/staff member. This helps reduce coding errors. 

Code groups can be associated to students and/or staff members. For students, this will limit the codes that are available for selection on the session for that student. 

For staff members the system will limit the codes that will be available to code on the session when the staff member is selected as the therapist. This will limit the codes available for selection to those listed in the applicable code group(s).
