Clinical & Coding Specifications
Clinical Context
A typical patient is an adult with advanced chronic heart failure experiencing symptomatic hypotension and low cardiac output due to impaired adrenergic signaling. The patient is evaluated in an outpatient infusion clinic or inpatient cardiology ward by a cardiologist or advanced practice provider. After medication review and hemodynamic assessment (blood pressure, heart rate, perfusion, and, when available, invasive or noninvasive cardiac output measurements), the team administers a single intravenous J2373 dose of phenylephrine hydrochloride (immphentiv) 20 micrograms per labeled indications to temporarily increase vascular tone and improve systolic blood pressure and organ perfusion. Vital signs and telemetry are monitored before, during, and after administration; the encounter includes medication preparation by pharmacy or nursing, IV access verification, and documentation of indication, dose, lot number, and patient response. Typical sites of service include hospital inpatient units, hospital outpatient infusion centers, and ambulatory specialty infusion clinics with emergency response capability.
