Understanding ABA Codes: A Quick Reference for Professionals


Accurate billing, compliance, and reimbursement are essential in delivering effective Applied Behavior Analysis (ABA) therapy. A key aspect of ensuring financial health and meeting regulatory standards is the use of ABA billing codes. These codes, including CPT codes, are crucial for documenting and billing adaptive behavior services. In this blog, we’ll provide an essential guide to ABA codes and their role in the success of your therapy services.

What Are ABA Codes?

ABA codes, specifically CPT codes, are a set of standardized numbers used to identify services provided in the field of applied behavior analysis. These codes are essential for insurance companies and healthcare providers to accurately document and bill for services rendered. They are crucial for proper reimbursement and maintaining ABA therapy compliance.

The American Medical Association maintains and updates CPT codes, which range from evaluation and assessment codes to treatment codes. These ensure that services are correctly identified, categorized, and compensated. Check out our additional resources for more information on various ABA data collection methods.

Key ABA CPT Codes and Their Uses

Understanding different CPT codes used in adaptive behavior therapy is essential for professionals. These codes are categorized into two broad groups: evaluation and assessment codes and treatment and intervention codes.

Evaluation and Assessment Codes

These codes are used when performing evaluations or assessments of a patient’s behavioral health. These codes cover one-on-one sessions between a technician and a physician or other qualified health care professional to review past data and findings.

Code 97151

This code is used for evaluations where a technician works directly with the patient, often discussing findings with a physician. It involves a face-to-face session between a technician and a patient, allowing for comprehensive assessments.

Code 97152

Used when one technician provides face-to-face behavioral assessment and treatment for a patient. This code is ideal for sessions focusing on direct care, focusing on individual needs.

Treatment and Intervention Codes

These codes focus on intervention and treatment protocols tailored for adaptive behavior services. They are used for ongoing treatment after administering assessments.

Code 97153

A common code for on-site sessions where a technician provides therapy to one patient individually. It addresses adaptive behavior and is used in a range of therapy treatment sessions for patient improvement.

Code 97154

This code is used when treating two or more patients during a face-to-face session. This is often used in group therapy settings where a technician addresses multiple patients.

Code 97155

A protocol modification for individual patients where a physician is involved. This code emphasizes the collaborative treatment process between technicians and physicians.

Code 97156

When family members are involved in treatment, this code is used. It accounts for sessions where the patient is present with their family to provide assistance and improve therapy outcomes.

Code 97157

This code is used for interventions involving multiple patients in a group environment. It’s designed for collaborative treatment where the focus is on improving social skills or group behavior.

Code 97158

Used for adaptive behavior sessions in group settings. It includes several patients working together under a behavioral therapist’s guidance.

Code 0373T

This is a protocol modification code, typically used when two or more technicians provide therapy to a group of patients.

Understanding ABA Modifiers

Protocol Modification (or modifiers) are additional codes added to CPT codes to provide more details about the service performed. They can reflect the complexity of the service, the environment in which it was provided, or whether specific conditions were met during the session.

Why Modifiers Matter in ABA Billing

Modifiers are crucial in ABA services as they impact billing and reimbursement. Accurate use of modifiers ensures that insurance companies understand the specific circumstances of the therapy service, which in turn influences the payment process.

Common ABA Modifiers

Modifiers are often used to define the specific category of service provided, whether it’s a treatment that involves a physician, a specialized service, or a service that involves additional healthcare professionals.

Impact of Modifiers on Reimbursement

Modifiers play a direct role in how much reimbursement a practice can receive for services rendered. Proper use of these codes can significantly impact a practice’s financial health, ensuring that all services are accurately reflected and reimbursed.

Best Practices for Using ABA Codes and Modifiers

To ensure accurate billing and maximize reimbursements, here are a few best practices:

  • Understand the billing codes: Familiarize yourself with the evaluation and treatment codes, ensuring each service is properly categorized.
  • Keep detailed records: Accurate documentation is essential for justifying the codes used during therapy sessions.
  • Use the correct modifiers: Modifiers help provide additional context about the service provided. Make sure you’re using them appropriately.
  • Stay updated: ABA codes and modifiers can change, so staying updated with the latest coding standards is important to avoid errors.
