September 20, 2024

On May 7, 2024, the Council of Autism Services Providers (CASP) released version 3.0 of their Applied Behavior Analysis Practice Guidelines for the Treatment of Autism Spectrum Disorder.

According to CASP, “The purpose of these practice guidelines is to inform decision making regarding the use of ABA as a medically necessary, efficacious, and cost-effective treatment to develop, maintain, or restore, to the maximum practicable extent, the functioning of individuals with ASD.”

Part 1: Overview

Section 1.1 – Executive Summary

Section 1.2 – General Principles and Considerations

This section:

  • Emphasizes that application of the guidelines and recommendations must be individualized to each patient as individualized treatment is a defining feature of ABA and a reason for its success in treating ASD

Section 3.3 – Medicaid Definitions

This section:

  • Clarifies State Medicaid agencies’ responsibility for determining what services are medically necessary for eligible people
  • Explains Medicaid’s rules for children under 21 years of age and that State Medicaid agencies cannot impose any definition of medical necessity on treatment for children that would limit the Early and Periodic Screening, Diagnostic, and Treatment (EPSDT) standard

Section 3.4 – Commercial Insurance Definitions

This section:

  • Explains that Commercial insurance plans commonly specify that services are covered only if the plan’s administrators determine that the services are medically necessary
  • Clarifies that definitions of medically necessary/medical necessity can vary somewhat among different funders
  • Explains that the medical necessity definitions will typically be found in the policy documents and must be disclosed to the plan member
  • Indicates that some insurers have adopted specialized medical necessity policies tailored to specific conditions or treatments, such as ABA treatment for ASD

Section 3.5 – Funder Review of Medical Necessity

This section:

  • States that when there are questions about the appropriateness or efficacy of services in an individual, the reviewing body should include a behavior analyst with experience in ABA treatment of ASD.

Part 4: Individualizing ABA Care

Section 4.1 – Assessment

This section:

  • Describes the initial assessment process and activities, which should include:
  • Record review of patient’s history
  • Interview with relevant stakeholders
  • Direct observation/measurement techniques to gain objective information about the behavior(s) of interest (e.g., FBA, skills-based assessments, standardized assessments)
  • Risk assessment for challenging behavior and mental health concerns
  • Emphasizes that there may need to be assessment from other professionals and discusses when to consult and/or refer to other professionals (e.g., medical conditions, other situations that may be outside of scope of training/competence)

Section 4.2 – Treatment Planning: Considerations and Models

This section:

  • Provides an overview of some of the activities that should be directed and coordinated by the behavior analyst
  • Describes considerations for many areas
    • Patient age
      • Treatment based on clinical needs and not constrained by age
    • Scope of treatment and treatment intensity
      • Use of focused ABA vs. comprehensive ABA
