Two Sets of Supervision Requirements
ABA practices must comply with two separate sets of supervision requirements:
These requirements are not identical, and in some cases they conflict. Understanding both is essential for compliance.
BACB Supervision Requirements
The BACB Ethics Code (effective January 2022) requires BCBAs to:
The BACB does not specify a minimum supervision ratio (e.g., 1 BCBA per X RBTs) — this is left to the BCBA's professional judgment based on the specific circumstances.
Payor Supervision Requirements
Most payors specify minimum supervision requirements in their ABA clinical policies. Common requirements include:
| Payor | Minimum Supervision Frequency | Maximum Ratio |
|---|---|---|
| Aetna | Monthly | Not specified |
| Anthem | Monthly | 1 BCBA per 10 RBTs |
| Cigna | Monthly | Not specified |
| UHC/Optum | Monthly | Not specified |
| Humana | Monthly | Not specified |
| Florida Medicaid | Monthly | 1 BCBA per 10 RBTs |
| Texas Medicaid | Monthly | Not specified |
| California DHCS | Weekly (for new RBTs) | 1 BCBA per 6 RBTs |
What Supervision Documentation Must Include
For billing compliance, supervision documentation must include:
Many payors require supervision documentation to be available upon request as part of a claims audit. Practices that cannot produce supervision documentation risk recoupment of all claims for the supervised period.
The Supervision Ratio Problem
The most common supervision compliance issue is maintaining an appropriate BCBA-to-RBT ratio as the practice grows. When a practice adds new clients faster than it adds BCBA capacity, the supervision ratio can quickly exceed payor limits.

When BACB and Payor Requirements Conflict
The most common conflict: a payor requires monthly supervision, but the BCBA's professional judgment indicates that a new or struggling RBT needs weekly supervision. In this case, the BCBA should provide weekly supervision (the higher standard) and document the clinical rationale.
The BACB Ethics Code takes precedence over payor requirements when it comes to professional standards. A BCBA who provides inadequate supervision to comply with a payor's cost-containment requirements may be in violation of the Ethics Code.
However, payors will only reimburse for the supervision they authorize. If a payor authorizes monthly supervision but the BCBA provides weekly supervision, the additional supervision sessions may not be reimbursable.
