Quick Explanation
This denial indicates that the payer has rejected the claim because the adaptive behavior assessment, typically billed under behavior identification codes such as CPT 97151, was deemed incomplete or lacked the necessary supporting documentation. Payers issue this code when the clinical record fails to demonstrate that all components of the assessment, including face-to-face administration, caregiver interviews, and final report writing, were fully completed. Without a finalized, signed interpretive report detailing the assessment results and treatment plan, the service cannot be reimbursed.
Common Causes for ABA31
Denials with code ABA31 typically happen for the following specific reasons:
- Submitting claims for CPT 97151 or 97152 prior to the completion, signing, and dating of the final clinical assessment report by the Qualified Healthcare Professional (QHP).
- Failing to document both the required face-to-face observation/testing time and the non-face-to-face scoring, analyzing, and report-writing time in the clinical record.
- Omission of mandatory assessment elements, such as standardized test protocols (e.g., Vineland, ABLLS-R), clinical observations, or explicit treatment recommendations within the final report.
- Billing for more assessment units than were clinically documented or exceeding the authorized time limits without submitting a complete diagnostic report to justify the additional units.
How to Prevent ABA31 Denials
To avoid receiving this denial in the future, implement these specific checks:
- Implement a strict billing hold that prevents claims for adaptive behavior assessments from being submitted until the final interpretive report is fully completed, signed, and uploaded to the client record.
- Train clinical staff to clearly document time-based increments, specifying the exact start/stop times and distinguishing between face-to-face patient contact and non-face-to-face report preparation as outlined by AMA CPT guidelines.
- Utilize EHR templates that mandate the inclusion of all necessary assessment components, including caregiver interviews, standardized testing scores, direct observations, and clinical recommendations.
- Conduct pre-billing audits to verify that the total units billed for CPT 97151 align precisely with both the documented hours and the pre-authorized limit specified by the patient's insurance plan.

Dear Appeals Department,
I am writing to appeal the denial of the above-referenced claim, which was denied with code ABA31: "Adaptive behavior assessment incomplete".
We are appealing the denial for code ABA31 (Adaptive behavior assessment incomplete) for services rendered. According to the American Medical Association (AMA) CPT coding guidelines for adaptive behavior assessments (specifically CPT 97151), this service encompasses both face-to-face assessment administration and the essential non-face-to-face time spent scoring, analyzing, and writing the final report. Attached, please find the comprehensive and fully executed adaptive behavior assessment report, which was completed, signed, and dated by a Qualified Healthcare Professional (QHP). This documentation includes all required components, such as standardized diagnostic protocol scores, direct clinical observations, caregiver interview summaries, and the resulting individualized treatment plan. Because the attached medical records clearly substantiate that the assessment was completed in its entirety and that all billed units represent actual time spent on these clinical activities, 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.
