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
