Clinical & Coding Specifications
Clinical Context
A patient in the emergency department presents with acute severe anxiety and an acute agitation episode after a traumatic event. The treating physician determines immediate short-acting benzodiazepine therapy is indicated for rapid anxiolysis and muscle relaxation. The clinician orders J3360 (injection, diazepam, up to 5 mg). A registered nurse prepares and administers the IV push or IM injection per facility protocol, documents dose, route, time, and patient response, and observes the patient for sedation, respiratory depression, and hemodynamic stability. If procedural sedation or additional monitoring is required, appropriate observation and adjunct medications or airway support are available. Billing is submitted by the facility using J3360 with applicable site-of-service modifiers (for example, emergency department or outpatient clinic) and any required payer-specific reporting. Vital signs, level of consciousness, and any adverse events are recorded in the medical record to support medical necessity and safe use of J3360.
