Clinical & Coding Specifications

Clinical Context

A 34-year-old patient arrives at an emergency department reporting sudden, severe panic with chest pain, shortness of breath, and imminent risk of self-harm after a traumatic event. The attending psychiatrist conducts an immediate crisis assessment and initiates an initial psychotherapy crisis intervention that addresses safety, stabilization, and brief problem-solving. After the first 60 minutes of crisis psychotherapy (90839), the patient remains in a life‑threatening crisis state requiring continued therapeutic intervention. The provider documents an additional 30 minutes of crisis psychotherapy and bills the add‑on service 90840.

Workflow:

Initial triage and medical clearance for life‑threatening symptoms.
Psychiatric crisis assessment and first 60 minutes of psychotherapy for crisis (90839) documenting objective signs of imminent danger and immediate need.
Continued psychotherapy for an additional 30 minutes to achieve stabilization, develop a safety plan, and coordinate immediate follow‑up care; documentation references initial 90839 session and reasons for extended time.
Coordination with inpatient or outpatient resources, notification of crisis team or family as appropriate, and final documentation of clinical findings, interventions, time spent, and disposition.
