Hospital-acquired pneumonia (HAP) in ICD10

This page explains how to code Hospital Acquired Pneumonia (HAP) in ICD10.

• HAP is indicated by linking two separate ICD10 codes:
  • (1) Iatrogenic, complication of medical or surgical care NOS PLUS
  • (2) One of the codes for specific types of organisms:
    • Pneumonia, bacterial
    • Pneumonia, fungal/yeast
    • Pneumonia, viral
    • Pneumonia, NOS

• Hospital-acquired pneumonia (HAP) is a type of nosocomial pneumonia that is contracted by a non-ventilated patient after at least 48 hours of being admitted to a hospital.
• If there is insufficient criteria for a Pneumonia, ventilator-associated (VAP) in ventilated patients with positive cultures, the patient may still have HAP.
• Patients from HSC Nursing Home Ward-NH RR2 and Grace Nursing Home Ward-NG - even though this is considered a nursing home type ward, patients who acquire a pneumonia and meet the HAP criteria will be called HAP.
