What This Code Means

A lung infection (pneumonia) that develops in patients who are on mechanical ventilation (breathing machines) for at least 48 hours.

Coding Tips

•Document the specific organism if identified through culture or testing for more complete coding
•Verify the patient was on ventilator support for at least 48 hours before pneumonia onset

Clinical Significance

Ventilator-associated pneumonia is a hospital-acquired infection developing in patients on mechanical ventilation for 48 hours or more. It is one of the most common and serious ICU-acquired infections, significantly increasing mortality, length of stay, and healthcare costs. This diagnosis indicates both the ventilator dependence and the infectious complication, representing maximal respiratory care complexity.

Documentation Requirements

✓Documentation that the patient was on mechanical ventilation for at least 48 hours before pneumonia onset
✓Clinical criteria for pneumonia (new infiltrate on imaging, fever, leukocytosis, purulent secretions)
✓Respiratory culture results identifying the causative organism (tracheal aspirate, BAL, or protected specimen brush)
✓Provider documentation explicitly stating 'ventilator-associated pneumonia'
✓Antibiotic regimen and treatment duration plan

Excludes 1 — Do NOT code together

ventilator lung in newborn (P27.8)

Use Additional Code

code to identify the organism, if known (B95.-, B96.-, B97.-)

Commonly Confused Codes

J95.850 — Mechanical complication of respirator is an equipment malfunction, not an infection J18.9 — Pneumonia unspecified does not capture the ventilator association J15.9 — Bacterial pneumonia unspecified could be used for the organism type but does not capture ventilator association J95.859 — Other complication of respirator is for non-specific ventilator complications, not VAP specifically
