The landscape of Applied Behavior Analysis (ABA) therapy is ever-evolving, with changes in Current Procedural Terminology (CPT) codes being a significant aspect that practitioners must stay abreast of. The American Medical Association (AMA) ensures that CPT codes accurately reflect the current healthcare environment, necessitating regular updates. For ABA therapy practices, understanding and adapting to these changes is crucial for accurate billing and reimbursement. As we move into 2024, several new CPT codes have been introduced, marking important updates for the field of ABA therapy.

Understanding the Essence of CPT Codes in ABA Therapy

CPT codes serve as the universal language across healthcare professionals, standardizing the documentation and billing for medical, surgical, and diagnostic services. Specifically, in ABA therapy, these codes facilitate the accurate tracking and billing of services provided to individuals with autism and other developmental disorders. The CPT Editorial Panel, consisting of expert volunteers from various healthcare sectors, oversees these updates, ensuring that the codes remain relevant and comprehensive.

ABA therapy primarily utilizes two categories of CPT codes:

  • Category I: For widely used medical procedures or services.
  • Category III: For emerging medical technologies, procedures, or services, reflecting the innovative and evolving nature of ABA therapy.

Each CPT code, comprising five characters, uniquely identifies specific therapeutic activities, making it easier for practitioners to bill for their services accurately.

The New ABA Therapy CPT Codes for 2024

The introduction of new CPT codes for ABA therapy in 2024 is a significant update that practitioners need to be aware of. These codes cover both adaptive behavior assessment and treatment, ensuring that the diverse range of ABA therapy services is comprehensively captured.

Adaptive Behavior Assessment Codes

These codes are designed to document and bill for the initial and ongoing assessments that are critical in developing and adjusting individualized treatment plans for clients.


This code is designated for a comprehensive behavior identification assessment conducted by a physician or another qualified healthcare professional. It encompasses face-to-face time with the patient and/or their guardian(s) or caregiver(s) for administering assessments, reviewing findings, or making recommendations. It also includes non-face-to-face activities such as assessing past data, scoring or interpreting assessments, and preparing reports or treatment plans. The billing for this code is calculated in 15-minute increments, emphasizing the detailed and thorough nature of the assessment process.


Tailored for behavior identification supporting assessments performed by one technician under the direction of a physician or other qualified healthcare professional, this code reflects the collaborative effort in evaluating a patient’s behavior. The assessment is conducted face-to-face, with the time also counted in 15-minute increments. This code underscores the role of technicians in providing essential support in the assessment process.


Specifically for behavior identification supporting assessments involving destructive behavior, this code is used when the assessment is conducted by a technician, administered by a physician or other qualified healthcare professional on-site, with the assistance of two or more technicians. It caters to patients who exhibit destructive behavior, requiring a specialized, face-to-face assessment in a controlled environment. The billing under this code is similarly based on 15-minute increments, highlighting the intensive nature of these assessments.

Adaptive Behavior Treatment Codes

These codes cater to the various treatment modalities within ABA therapy, from one-on-one sessions to group and family treatments.


This code applies to protocol adaptive behavior treatment performed by a technician under the supervision of a qualified healthcare professional. It focuses on one-on-one, face-to-face treatment with a single patient, emphasizing individualized care. The treatment duration is measured in 15-minute increments, allowing for flexibility based on the patient’s needs.


Group adaptive behavior treatment by protocol, conducted by a technician under the direction of a healthcare professional, falls under this code. It is designed for face-to-face treatment involving two or more patients, fostering a group therapy environment. This setup encourages social interaction and peer learning, with billing also in 15-minute increments.


For adaptive behavior treatment with protocol modification performed by a physician or other qualified healthcare professional, this code includes the possibility of simultaneous direction of a technician. It’s tailored for one-on-one sessions, allowing for personalized adjustments to the treatment protocol based on the patient’s progress. The face-to-face treatment with a single patient is also billed in 15-minute increments.


This code is used for family adaptive behavior treatment with protocol modification, conducted with or without the patient present, face-to-face with a guardian(s) or caregiver(s). It highlights the importance of involving the patient’s support system in the therapy process, providing guidance and strategies to guardians or caregivers for reinforcing treatment goals at home.


Multiple family adaptive behavior treatment with protocol modification is captured by this code. It involves sessions without the patient, conducted face-to-face with more than one group of guardians or caregivers. This approach facilitates a support network among families, sharing experiences and strategies under the guidance of a healthcare professional.


Group adaptive behavior treatment with protocol modification, performed by a healthcare professional and involving multiple patients, utilizes this code. It emphasizes a collaborative treatment environment where patients can benefit from peer interactions under professional supervision.


This code is specific to adaptive behavior treatment with protocol modification performed by a technician, focusing on one-on-one, face-to-face sessions with a single patient. It allows for direct, personalized treatment, adapting the protocol as needed to meet the individual’s therapeutic goals.
