DBT Therapy Billing: CPT Codes and Insurance Guide

Dialectical Behavior Therapy (DBT) is one of the most evidence-based treatments for borderline personality disorder, chronic suicidality, and emotion dysregulation — but billing it correctly requires knowing which CPT codes apply, how to pair them with the right ICD-10 diagnoses, and how to navigate insurance coverage for multi-component DBT programs.

Which CPT Codes to Use for DBT

DBT does not have its own dedicated CPT code. Like EMDR and CBT, it is billed under standard psychotherapy codes based on session length and format:

• 90837 — 60-minute individual psychotherapy. The standard code for full individual DBT sessions, which typically run 50–60 minutes.
• 90834 — 45-minute individual psychotherapy. Used when sessions run shorter, often during early skills-training phases.
• 90832 — 30-minute individual psychotherapy. Rarely used for standard DBT but appropriate for brief phone coaching follow-ups billed as in-person sessions.
• 90853 — Group psychotherapy. Used for DBT skills training groups, billed per participant. See the group therapy billing guide for details on how 90853 works.
• 90847 — Family therapy with patient present. Relevant when DBT includes family sessions to teach skills and reduce validation failures at home.
• 90846 — Family therapy without patient present. Used when therapists coach family members separately on DBT validation and skills.

ICD-10 Diagnosis Codes for DBT Clients

DBT was originally developed for borderline personality disorder but is now used for a range of high-emotion-dysregulation presentations. Common diagnosis codes:

• F60.3 — Borderline personality disorder. The primary diagnosis for most standard DBT programs. Insurers recognize this diagnosis as a clinical indication for DBT.
• F43.12 — PTSD, chronic. DBT-PE (Prolonged Exposure variant) is increasingly used for trauma-focused work once clients achieve baseline stability.
• F41.1 — Generalized anxiety disorder. DBT is evidence-supported for anxiety presentations with significant emotion dysregulation.
• F32.1, F33.1 — Major depressive disorder, moderate. DBT is a front-line treatment for chronic depression with suicidal ideation.
• F50.01, F50.02 — Anorexia nervosa; F50.2 — Bulimia nervosa. DBT has strong evidence for eating disorders with emotional triggers.

Billing DBT Skills Training Groups

Standard DBT is a multi-component program: individual therapy plus skills training group, plus phone coaching. Each component is billed separately:

• Individual therapy session: 90837 per session, per client.
• Skills training group: 90853 per session, per participant. Even if the group runs 90 minutes, 90853 is a flat per-session code — there is no time-based multiplier.
• Phone coaching: Generally not separately billable to insurance unless structured as a formal 30-minute session and billed as 90832. Brief coaching calls are typically bundled into the overall treatment fee.

If you are the individual therapist and also run the skills group, you may bill both codes for the same client on the same date — they are distinct services. Document that the group and individual session were separate in your records.

Insurance Coverage for DBT

Because DBT bills under standard psychotherapy and group therapy codes, most major insurers cover it if the codes and diagnoses are covered under the client's mental health benefits. A few things to watch for:

• Session limits: Some plans cap outpatient sessions (e.g., 30 sessions per year). A full DBT program involves individual therapy plus group weekly — that can easily hit 80+ billable sessions per year. Verify benefits carefully and consider prior authorization early.
• Medical necessity for F60.3: BPD diagnosis can trigger heightened scrutiny from some insurers. Write notes that clearly document functional impairment, treatment goals, and measurable progress.
• Out-of-network DBT: Many DBT specialists operate out-of-network. Clients can use OON benefits and superbills to seek partial reimbursement for both individual and group components.

DBT on a Superbill

A DBT superbill follows the same format as any psychotherapy superbill: CPT code, date of service, session fee, ICD-10 diagnosis code(s), and provider credentials. For group sessions, each participant receives their own superbill listing CPT 90853. Superbilled generates compliant superbills for both individual and group DBT sessions, making it straightforward to support clients seeking OON reimbursement.
