Final answer:
When coding a documented ventilator-associated pneumonia (VAP), the specific code for VAP is coded first, the organism is coded as a secondary code if known, and an additional code for the type of pneumonia is coded.
Step-by-step explanation:
When coding a documented ventilator-associated pneumonia (VAP), the following codes should be assigned:
- The specific code for ventilator-associated pneumonia is coded first. This is because VAP is the primary diagnosis that led to the patient's hospitalization.
- The organism is coded as a secondary code if known. This means that if the specific bacteria causing the pneumonia is known, a secondary code should be assigned to identify it.
- An additional code for the type of pneumonia, such as lobar or pneumonia NOS, is coded. This provides further specificity about the type of pneumonia.
