What Billing Codes are Used for Bcba-led Parent Training Sessions?

For BCBA-led parent training sessions, there are three primary adaptive behavior treatment codes used under the ABA CPT codes 2026 guidelines. These codes ensure that coaching and guidance for families are documented and billed accurately:

  • CPT 97156: This is the core code for family or caregiver adaptive behavior treatment guidance. It is used for one-on-one sessions where a BCBA teaches parents strategies to support their child’s progress, such as communication techniques or managing behaviors at home.
  • CPT 97151: This code is used for the initial assessment and treatment planning. It covers the time a BCBA spends evaluating a child’s profile and designing specific training goals for the parents.
  • CPT 97155: This code is utilized for protocol modification. In the context of parent training, it applies when a BCBA adjusts the coaching plan based on new data or the family’s ongoing progress.
  • CPT 97157: While less common at Heart Core ABA, this code is used for sessions delivered in a group family/caregiver setting.

Only a Board Certified Behavior Analyst (BCBA) is qualified to deliver services under these codes. Additionally, the HA modifier is typically required on CPT 97156 claims to indicate that the service is a family/caregiver treatment.
