CPT Code Overview

CPT 0373T describes adaptive behavior treatment with protocol modification, billed in 15-minute increments for technicians' time spent face-to-face with a patient. The service requires administration by a physician or other qualified health care professional who is on site, assistance from two or more technicians, care for a patient who exhibits destructive behavior, and completion in an environment customized to the patient's behavior.

Service type: Adaptive Behavior Treatment (emerging/behavioral health)

Typical site of service: Office (POS 11)

Clinical Context

A 7-year-old child with a diagnosis of autism spectrum disorder (F84.0) exhibits frequent destructive behaviors (self-injury and property damage) during outpatient visits. The child presents to an office (POS 11) for adaptive behavior treatment with protocol modification. A physician or other qualified health care professional is on site, supervises the session, and two or more trained technicians provide direct, face-to-face intervention in an environment customized to reduce triggers and support the child’s needs. Sessions are documented in 15-minute increments of technicians’ time and include real-time adjustments to the behavior intervention plan based on observed antecedents and consequences. Documentation includes the supervising clinician’s presence, number of technicians, description of destructive behaviors, environmental modifications, and specific protocol changes during each timed interval.

Coding Specifications

• Modifiers:

• 59: Distinct Procedural Service — Use when 0373T is performed on the same date as another non-overlapping procedure or service and the procedures are not typically reported together; documentation must support distinct service and separate procedural work.

• 95: Synchronous Telemedicine Service Rendered via a Real-Time Interactive Audio and Video Telecommunications System — Use when portions of the supervised adaptive behavior treatment with protocol modification meet requirements for synchronous telemedicine; documentation must reflect real-time interactive audiovisual technology and the supervising clinician’s on-site presence if required by the code descriptor.

• Associated provider taxonomies and specialties:

• 103T00000X — Psychologist

• 1041C0700X — Clinical Social Worker

• 101YM0800X — Mental Health Counselor

• 2084P0800X — Psychiatry & Neurology Physician

• 106H00000X — Marriage & Family Therapist

Related Diagnoses

• F84.0 — Autistic disorder

  Relevance: Core indication for adaptive behavior treatment; destructive behaviors associated with autism are commonly targeted by protocol-based interventions requiring technician-delivered sessions and supervision.

• F84.5 — Asperger's syndrome

  Relevance: Related neurodevelopmental condition with social-communication deficits and potential behavior challenges that may be addressed through adaptive behavior treatment.

• F84.9 — Pervasive developmental disorder, unspecified

  Relevance: Non-specific pervasive developmental disorder that can present with maladaptive or destructive behaviors addressed by individualized adaptive behavior protocols.

• F90.9 — Attention-deficit hyperactivity disorder, unspecified type

  Relevance: Behavioral dysregulation and impulsivity seen in ADHD can contribute to maladaptive behaviors and be targeted within behavior treatment protocols.

• F93.9 — Childhood emotional disorder, unspecified

  Relevance: Emotional and behavioral disturbances in childhood that may manifest as destructive behaviors amenable to protocol-driven adaptive behavior interventions.

Related CPT Codes

• 97151 — Behavior identification assessment

• 97153 — Adaptive behavior treatment by protocol

• 97155 — Adaptive behavior treatment with protocol modification

• 97156 — Family adaptive behavior treatment guidance

Clinical workflow relationships:

• 97151 is typically used earlier in the care pathway to assess and identify target behaviors and develop a behavior intervention plan prior to time-based treatment codes.

• 97153 represents time-based technician-delivered adaptive behavior treatment following an established protocol; 0373T is similar but requires multiple technicians and on-site physician or qualified professional.

• 97155 describes adaptive behavior treatment with protocol modification provided by a therapist; it is related to 0373T as both involve protocol modification, with 0373T specifically defining technicians’ face-to-face time and supervision requirements.

• 97156 provides family guidance related to adaptive behavior treatment and may be used in conjunction with technician-delivered sessions for caregiver training.

Common pairings and alternatives:

• 97151 often precedes any of the time-based treatment codes (97153, 97155, 0373T).

• 97153 or 97155 may be used as alternatives depending on the staffing, supervision, and complexity of protocol modification relative to 0373T.

National mean rates for 0373T place Medicare substantially below BUCA (average commercial), with Medicare mean effectively at $0.00 in the provided input versus BUCA at $21.23. This positions average commercial coverage notably higher than the Medicare benchmark in the available national data.

Dispersion measured as the interquartile range (P75 minus P25) varies by payer: Blue Cross Blue Shield shows the widest spread (49.00 - 12.79 = 36.21), followed by Cigna (46.00 - 19.00 = 27.00). UnitedHealth Group is the tightest (16.00 - 6.00 = 10.00), with Aetna (24.00) and BUCA (18.00) in between. The table and chart below present the full numeric breakdown.
