What This Code Means

A patient who requires a mechanical ventilator (breathing machine) to assist with or completely manage their breathing.

Coding Tips

•This code indicates dependence on a ventilator; specify if it's full-time or part-time dependence
•Always code the underlying condition requiring ventilator support in addition to this status code

Clinical Significance

This code represents complete dependence on mechanical ventilation for breathing, indicating severe respiratory compromise with extremely high mortality risk and intensive care needs. These patients require 24/7 monitoring, specialized nursing care, and complex respiratory management protocols.

Documentation Requirements

✓Confirmation of ventilator dependence for breathing
✓Type of ventilatory support (invasive vs non-invasive)
✓Ventilator settings and parameters
✓Tracheostomy status if applicable
✓Duration of ventilator dependence
✓Weaning attempts or prognosis
✓Respiratory therapy requirements
✓Underlying condition requiring ventilation
