Quick Explanation
This denial code indicates that the health plan rejected the claim or authorization request because the Functional Behavior Assessment (FBA) was deemed incomplete under their clinical guidelines. To be eligible for reimbursement, an FBA must contain all mandated structural components, such as direct clinical observations, caregiver interviews, and a formalized behavioral intervention plan. If any of these required elements are missing or insufficiently documented in the clinical record, the payer will issue this denial.
Common Causes for BH15
Denials with code BH15 typically happen for the following specific reasons:
- Submitting the FBA claim without documenting the mandatory direct clinical observation hours or environmental assessments.
- Omitting key structural elements of an FBA report, such as operational definitions of target behaviors, antecedent-behavior-consequence (ABC) data, or a functional hypothesis.
- Failing to include required standardized assessment tools, caregiver rating scales, or parent interview summaries within the final clinical report.
- Billing behavioral assessment CPT codes (e.g., 97151 or 97152) prior to the clinical report being fully completed, signed, and dated by the supervising Board Certified Behavior Analyst (BCBA).
How to Prevent BH15 Denials
To avoid receiving this denial in the future, implement these specific checks:
- Implement a standardized pre-submission checklist for all FBAs to verify the presence of direct observations, ABC data, caregiver input, and clinical recommendations.
- Ensure that the supervising BCBA signs, dates, and locks the completed assessment report in the EHR before billing department generates the claim.
- Conduct regular clinical documentation training aligned with specific insurance carrier policies regarding the minimum required hours and documentation standards for behavior identification codes.
- Configure EHR templates to prevent finalization of behavioral assessment notes if mandatory fields, such as the behavioral hypothesis or baseline data, are left blank.

Denial Code: BH15 - Functional behavior assessment incomplete
Dear Appeals Department,
I am writing to appeal the denial of the above-referenced claim, which was denied with code BH15: "Functional behavior assessment incomplete".
We are formally appealing the denial of CPT code 97151 under denial code BH15 (Functional behavior assessment incomplete) for services provided to the patient on the specified dates of service. Upon a thorough audit of the clinical record, we have confirmed that a comprehensive and complete Functional Behavior Assessment (FBA) was performed and documented in strict accordance with the American Medical Association (AMA) CPT billing guidelines and Behavior Analyst Certification Board (BACB) professional standards. The enclosed clinical report explicitly details all necessary components, including clearly defined target behaviors, direct observational data, antecedent-behavior-consequence (ABC) analysis, caregiver interviews, and a formalized behavioral hypothesis with targeted treatment recommendations. Since all clinical and structural requirements for a complete behavioral assessment have been met and are thoroughly documented in the attached records, we respectfully request that this denial be overturned and the claim be processed for immediate payment.
Attached please find:
1. A copy of the original claim.
2. The relevant medical records supporting the service.
3. [Any other supporting documents].
We respectfully request that you reprocess this claim for payment.
Sincerely,
[Your Name]
