Operation Definition

Treatment of an individual with addictive behavior by behavioral, cognitive, psychoanalytic, psychodynamic or psychophysiological means

Procedure Overview

Individual psychotherapy for substance use applies structured psychological treatment methods, such as cognitive-behavioral, psychodynamic, or psychoanalytic techniques, to help a single patient understand and change the thought patterns and emotional drivers behind their addictive behavior. It goes beyond practical coping advice, aiming to uncover underlying psychological factors like trauma, anxiety, or ingrained thought distortions that fuel substance use.

A licensed therapist typically leads these sessions using a defined therapeutic framework rather than open-ended conversation, and the approach chosen often depends on the patient's specific diagnosis and treatment goals. This form of therapy is commonly woven into a broader substance abuse treatment plan alongside detoxification and counseling, addressing the psychological dimension of recovery once the patient is stable enough to engage in deeper reflective work.

Anatomy & Axis Detail

Psychodynamic

Psychodynamic individual psychotherapy examines how unconscious conflicts, early relational patterns, and unresolved emotional material contribute to a patient's substance use, using a less intensive and typically shorter-term framework than formal psychoanalysis. The clinician helps the patient gain insight into recurring emotional patterns and defense mechanisms, such as using substances to manage unacknowledged anger or attachment insecurity, without the frequency or free-associative technique of classical analysis. This modality suits patients ready to explore underlying psychological drivers of their use but not engaged in a full analytic treatment course. Documentation distinguishes it from psychoanalysis by intensity and technique and from cognitive-behavioral approaches by its focus on insight into unconscious material rather than present-day thought and behavior change.

Coding & Documentation

Coders assign this code when documentation shows a one-on-one session using a named or describable psychotherapeutic method, such as cognitive-behavioral therapy or psychodynamic techniques, aimed at treating the patient's addictive behavior. The therapist's credentials and the specific technique applied should be identifiable in the note.

A common error is coding psychotherapy based only on the word appearing in a progress note, without documentation of an actual psychological treatment method being applied, when the session was really supportive counseling. Coders should also watch for sessions that shift between individual and family or group formats within one note, since only the individual portion supports this code.

Commonly Confused With

The main point of confusion is with individual counseling; psychotherapy involves a defined psychological treatment method targeting root causes, while counseling is generally more supportive and behaviorally focused without that formal clinical framework. It can also be mistaken for psychotherapy codes in the Mental Health section when a patient has a co-occurring psychiatric diagnosis, so coders need to confirm the session's documented focus was the patient's addictive behavior to assign it correctly under substance abuse treatment.
