Quick Explanation
Denial code B2 indicates that a claim has been denied because the provider failed to document the required parent training or family guidance hours as mandated by the patient's treatment plan or specific payer policies. In behavioral health and Applied Behavior Analysis (ABA) therapy, active caregiver participation is a strict clinical requirement, and failure to provide documented evidence of these sessions results in payment rejection for the associated services.
Common Causes for B2
Denials with code B2 typically happen for the following specific reasons:
- The clinical documentation failed to record the specific parent training sessions (such as CPT 97156 or 97157) required to support ongoing ABA services.
- Parent training hours were completed but the corresponding session notes, sign-in sheets, or attendance logs were not submitted with the authorization or claim review.
- The frequency or duration of the documented parent training sessions did not meet the minimum threshold required by the payer's clinical coverage guidelines.
- Caregiver signatures or verification of participation were missing from the behavioral therapy medical records.
How to Prevent B2 Denials
To avoid receiving this denial in the future, implement these specific checks:
- Establish a mandatory parent training log within the EHR system to easily track, verify, and export caregiver involvement hours.
- Conduct proactive internal audits of behavioral health claims to ensure CPT code 97156 is billed and documented according to the approved prior authorization.
- Require written or electronic caregiver signatures on all session notes to serve as indisputable proof of parent training compliance.
- Train clinical and administrative staff on individual payer policies regarding the mandatory ratio of parent training hours to direct therapy hours.

Denial Code: B2 - Parent training hours not documented
Dear Appeals Department,
I am writing to appeal the denial of the above-referenced claim, which was denied with code B2: "Parent training hours not documented".
We are writing to formally appeal the denial of this claim under denial code B2 (Parent training hours not documented). In accordance with the American Medical Association (AMA) CPT guidelines for Adaptive Behavior Services, specifically regarding CPT 97156 (Family Adaptive Behavior Treatment Guidance), parent training was successfully conducted and fully documented within the patient's clinical file. Enclosed you will find the comprehensive parent training logs, individual clinical session notes detailing the caregiver's active participation, and progress notes signed by the supervising Qualified Healthcare Professional (QHP). This documentation clearly demonstrates that the parent training hours met all clinical policy thresholds and medical necessity requirements, and 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]
