Play Therapy Billing: CPT Codes and Reimbursement

Play therapy is a widely used modality for children, but it has no dedicated CPT code. Billing it correctly means using the standard psychotherapy codes — and knowing how to document play-based interventions in a way that satisfies insurance reviewers who may not be familiar with the modality.

No Dedicated Play Therapy CPT Code

There is no CPT code that specifically says "play therapy." Insurance companies bill play therapy under the same time-based individual psychotherapy codes used for all talk therapy:

• 90832 — 16–37 minutes of psychotherapy. Sometimes used for shorter check-in sessions with children between full play therapy sessions.
• 90834 — 38–52 minutes of psychotherapy. Often the right code for 45-minute child sessions.
• 90837 — 53+ minutes of psychotherapy. Used for full 60-minute play therapy sessions.
• 90791 — Psychiatric diagnostic evaluation. The correct code for the initial assessment, often including child observation and parent interview.

Select the code that matches the actual session time, just as you would for any other therapy service.

How to Document Play Therapy for Insurance

The biggest risk for play therapy claims is insufficient documentation. Insurers need to see clinical justification for each session — not just "played with sandbox" but clear therapeutic intent and outcome tracking. Good play therapy notes include:

• Treatment focus: What theme or therapeutic goal was the primary focus of this session? (e.g., "processing attachment disruption through family figurine play")
• Modality and techniques used: Name the approach — child-centered, directive, Theraplay, sandtray. Be specific: "Client used sandtray to recreate school environment and practiced assertive communication with teacher figure."
• Client response and affect: Describe how the child engaged, emotional tone, and any breakthroughs or avoidances.
• Functional progress: Tie session themes to measurable treatment goals — "Client demonstrated increased frustration tolerance compared to last session per parental report."
• Parent consultation: If you met briefly with a parent after the session, note it. Extended parent sessions may warrant CPT 90847 (family therapy with patient present).

Diagnosis Codes for Play Therapy Clients

Play therapy is used across a broad range of childhood presentations. Common ICD-10 codes paired with play therapy sessions:

• F43.21, F43.22, F43.23 — Adjustment disorder (depressed, anxious, or mixed emotional features). Very common in children experiencing family change, school transitions, or loss.
• F90.0–F90.9 — ADHD. Play therapy is used adjunctively for executive function and social skill development.
• F43.10–F43.12 — Post-traumatic stress disorder. Trauma-focused play therapy (TF-CBT) addresses developmental trauma.
• F94.1 — Reactive attachment disorder. Play-based attachment work is a cornerstone treatment.
• F41.1 — Generalized anxiety. Child-directed play therapy addresses anxiety through graduated exposure via play.

Insurance Coverage and Out-of-Network Options

Most insurers cover play therapy when billed under appropriate psychotherapy codes with a covered diagnosis. The modality itself is not excluded — it is the code and diagnosis that determine coverage. Challenges arise when:

• The documented diagnosis does not clearly support medical necessity for ongoing therapy sessions.
• Session notes do not tie play-based activities to measurable therapeutic goals.
• The therapist lacks licensure recognized by the insurer (e.g., some plans require LCSW, LPC, or PhD — check credentialing requirements).

Many play therapists practice out-of-network. Parents can use their OON benefits and submit a superbill to seek partial reimbursement. Superbilled makes it easy to generate superbills for child play therapy sessions, listing the correct CPT code, date, fee, and diagnosis.
