Clinical & Coding Specifications
Clinical Context
A 3-year-old child is admitted to the pediatric intensive care unit with respiratory failure due to severe bronchiolitis requiring intubation and mechanical ventilation. The child is critically ill, unstable, and requires continuous intensive monitoring, ventilator management, vasoactive support, and frequent reassessments by the attending pediatric intensivist. The attending physician performs a focused follow-up visit the next day to evaluate current organ support, ventilator settings, sedation requirements, fluid balance, and to discuss ongoing goals of care with the bedside team and the child’s parents. Documentation includes the patient’s current vital signs, ventilator parameters, assessment of end-organ perfusion, changes in medications or interventions, time spent reviewing the patient’s course and coordinating care, and a statement that the child remains critically ill.
Typical site of service: Inpatient pediatric intensive care unit (PICU).
Service type: Follow-up critical care visit for a pediatric patient ages two to five years in an inpatient setting.
