Cognitive Behavioral Therapy (CBT) is billed under the standard psychotherapy CPT codes — there is no special CBT billing code. But the modality does shape your documentation and occasionally opens the door to health behavior codes for specific presentations.
CBT Uses Standard Psychotherapy Codes
CBT is a psychotherapy modality, not a separate billing category. Use the time-based individual psychotherapy codes based on session duration:
- 90832 — 16–37 minutes of psychotherapy (~$75–$125 privately)
- 90834 — 38–52 minutes of psychotherapy (~$100–$175 privately)
- 90837 — 53+ minutes of psychotherapy (~$150–$250 privately) — the most common code for full CBT sessions
It does not matter that the session is CBT, DBT, EMDR, or psychodynamic — the CPT code is determined by session length, not technique. Using a different code because you practice CBT would be incorrect.
Documentation Tips for CBT Sessions
CBT has a structured, technique-driven approach that supports clear session documentation:
- Agenda and focus: Note the session agenda (e.g., "Review homework, cognitive restructuring for catastrophizing, assign behavioral activation task")
- Specific techniques used: Name the intervention clearly — "Socratic questioning to examine automatic thoughts about failure," or "Developed fear hierarchy for social situations"
- Homework assigned and reviewed: CBT typically involves homework; document what was assigned last session and what the client completed
- Symptom tracking: PHQ-9, GAD-7, or other validated measures used in CBT should be documented regularly
- Progress toward treatment goals: Specific, measurable goals are a CBT hallmark — document movement toward them
Health Behavior Codes: When They Apply
A subset of CBT interventions qualifies for health behavior assessment and intervention codes (96152–96159) rather than psychotherapy codes. These apply when:
- The intervention targets health behavior change (smoking cessation, medication adherence, pain management, chronic disease self-management)
- The client does not have a psychiatric diagnosis as the primary treatment focus
- The goal is improving health outcomes related to a physical health condition
Examples: CBT for chronic pain without a comorbid depressive disorder; behavioral activation for fatigue in cancer patients; CBT for insomnia (CBT-I) when the primary diagnosis is a sleep disorder without a comorbid psychiatric disorder.
- 96156 — Health behavior assessment, first 30 minutes
- 96158 — Health behavior intervention, individual, first 30 minutes
- 96159 — Health behavior intervention, individual, each additional 15 minutes
If the client has a primary psychiatric diagnosis (anxiety, depression, PTSD), use psychotherapy codes — not health behavior codes.
Prior Authorization for CBT
CBT itself does not require prior authorization beyond the standard outpatient therapy PA rules. One exception: Exposure and Response Prevention (ERP) for OCD — some managed care plans require PA after a set number of sessions and may request documentation that treatment is ERP-based. Include your treatment model in PA requests for OCD to support medical necessity.
CBT on a Superbill
A superbill for a CBT session looks the same as any psychotherapy superbill. List the appropriate CPT code (90837 for a 60-minute session), the client's ICD-10 diagnosis (e.g., F41.1 for GAD, F33.1 for MDD moderate), date of service, and fee charged. Superbilled generates these in under 60 seconds — no need to manually fill out forms for every session.
