Code Conversion Table
September 4, 2018
To help payers and providers achieve consistency in utilization and implementation of the new codes, we have prepared this coding conversion crosswalk. It indicates the most common HCPCS and 2014 Category III CPT codes that have been or are being used by payers to report ABA services, and cross references those older codes to the 2019 Category I and III CPT codes. The crosswalk is organized by the essential elements of ABA services: assessment and reassessment, treatment plan development and revision, direct treatment of individual clients, direction of technicians by a professional behavior analyst or other qualified healthcare professional (QHP), family or caregiver training, and group treatment. For each new code, the crosswalk also indicates which personnel must attend each service in order to bill for that service as well as applicable time increments.
We hope this information will foster an understanding of how the 2019 CPT codes are intended to be reported and encourage uniform reporting of ABA services across providers, payers, and states.
