BCBA Supervision vs. Direct Therapy

A BCBA's time can be billed differently depending on what they are actually doing:

  • Direct therapy (97155): BCBA is hands-on with the patient, delivering treatment and modifying the behavior protocol
  • Assessment (97151): BCBA is evaluating, observing, and writing treatment plans
  • Caregiver training (97156): BCBA is training the family/caregivers (patient may or may not be present)
  • Supervision of technicians: Generally NOT separately billable under most commercial plans — it is considered included in the overall authorization

What Is NOT Separately Billable

Most payers do NOT pay separately for:

  • BCBA supervision time (e.g., watching the RBT from across the room)
  • Chart review and documentation (outside of the assessment code)
  • Phone calls with families or school staff (unless part of 97156)
  • Travel time between appointments

State Medicaid Exceptions

Some state Medicaid programs do allow billing for supervision activities under a distinct code. Check your state's ABA billing manual for state-specific billable activities.

Documentation Best Practices

For each billable BCBA session, document:

  • Start and end time (to support the number of units billed)
  • The specific activity (assessment, protocol modification, caregiver training)
  • Patient present: yes/no (required for some codes)
  • Any protocol changes made during the session
  • BCBA signature and credentials
