ICD-10 Code J95.851 – Ventilator Associated Pneumonia (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code J95.851 – Ventilator associated pneumonia
What it is
Use this code for pneumonia that develops in a patient on mechanical ventilation. It describes an infection linked to ventilator use rather than community or routine hospital-acquired pneumonia.
Clinical signs
Clinical features vary; refer to documentation. Typical references note new or worsening infiltrates with respiratory decline, increased secretions, fever, or leukocytosis in a ventilated patient.
When to use this code
Assign J95.851 when the provider documents ventilator associated pneumonia, VAP, or equivalent wording. Use it for pneumonia occurring after intubation and supported by the charted clinical assessment. If the record only says pneumonia in a ventilated patient, check documentation before coding.
Do not use for
Do not use this code for aspiration pneumonia, community-acquired pneumonia, or unspecified hospital-acquired pneumonia unless the provider specifically documents ventilator association. Check documentation when the diagnosis is unclear.
Coding tip
Look for explicit provider wording tying the pneumonia to mechanical ventilation before assigning J95.851.
