To develop a revised comprehensive proposal for the addition of adaptive behavior services codes, a multidisciplinary work group was formed. The work group drafted assessment codes for intake and monitoring progress for early intensive behavioral intervention and functional behavioral assessment of severe destructive behavior. The goal was to propose two sets of CPT codes (assessment and treatment) to form the basis for reimbursable ABA services.

In August 2013, the multidisciplinary work group submitted a code change application to the CPT Editorial Panel.
