Quick Explanation
Denial code BH20 indicates that a behavioral health claim for crisis intervention services was rejected because the provider did not adhere to or properly document the required clinical and administrative crisis protocols. This typically occurs when the medical record fails to prove the existence of an imminent, acute psychiatric crisis, or lacks critical elements like precise time tracking and a documented safety plan.
Common Causes for BH20
Denials with code BH20 typically happen for the following specific reasons:
- Failure to document exact start and stop times to support time-based crisis codes such as CPT 90839 and 90840.
- Absence of clinical documentation showing 'imminent risk' of danger to self or others, which is required to justify a crisis-level service.
- Lack of a written, collaborative safety or crisis stabilization plan in the patient's medical record for the date of service.
- Failure to notify the payer or obtain required retrospective authorization within the contractually mandated timeframe following an emergency encounter.
How to Prevent BH20 Denials
To avoid receiving this denial in the future, implement these specific checks:
- Utilize EHR templates designed specifically for crisis intervention that require mandatory fields for start/stop times, specific risk assessments, and safety planning.
- Conduct regular clinical documentation improvement (CDI) audits to verify that behavioral health clinicians are clearly articulating the severity of the crisis and the specific interventions used to de-escalate it.
- Establish clear internal administrative workflows to ensure that payers are notified of emergency behavioral health services within 24-48 hours of the encounter.
- Train clinical staff on AMA CPT coding guidelines for 90839/90840 to prevent billing crisis codes for standard, non-urgent psychotherapy sessions.

Denial Code: BH20 - Crisis intervention protocols not followed
Dear Appeals Department,
I am writing to appeal the denial of the above-referenced claim, which was denied with code BH20: "Crisis intervention protocols not followed".
We are appealing the denial of claim number [Insert Claim Number] for crisis intervention services (CPT [Insert CPT Code]) under denial code BH20. According to AMA CPT and CMS guidelines, crisis intervention codes are appropriate when a patient presents with an acute, life-threatening, or highly complex psychiatric condition requiring immediate de-escalation. The attached clinical documentation clearly establishes that the patient was in a state of imminent crisis, detailing the specific risk factors, the active therapeutic interventions used to stabilize the patient, and the collaborative safety plan established. Furthermore, the records explicitly document the precise start and stop times, demonstrating that the time thresholds for the billed codes were fully met. We request that you review the enclosed medical records, which confirm compliance with all clinical protocols, and process this claim 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]
