The current Category I CPT codes used for ABA therapy services are standardized codes established by the American Medical Association to identify specific session types. These codes are typically billed in 15-minute units.

The most common Category I codes include:

• 97151: Used for behavioral assessments conducted by a Board Certified Behavior Analyst (BCBA) to create initial or ongoing treatment plans.
• 97153: Covers direct, one-on-one therapy provided by a Registered Behavior Technician (RBT) under the supervision of a BCBA to work on skill-building and behavior goals.
• 97155: Used for protocol modification, which occurs when a BCBA supervises a session and adjusts the treatment plan based on real-time observations of the child.
• 97156: Applies to family adaptive behavior treatment guidance, involving caregiver training sessions to help families implement therapeutic techniques at home.

Other codes mentioned in the context of ABA treatment services include 97157 and 97158. Accurate selection of these codes depends on the specific service provided and the credentials of the professional delivering the care.
