About the GZ5 Code Range

These procedures treat an individual with a mental health disorder by working with behavior, thinking, emotions, relationships, or body processes.

The fourth character distinguishes interactive therapy using nonspoken aids, behavioral therapy to change actions, and cognitive therapy to address thinking errors. It also separates interpersonal work on relationships, psychoanalysis and psychodynamic work on inner conflicts, and supportive therapy for emotional support. Cognitive-behavioral therapy combines thinking and behavior approaches; psychophysiological therapy monitors and changes body processes. The fifth through seventh characters each use the None qualifier.
