Official Coding Guidelines

VAP: assign J95.851 only with provider documentation; add organism code

d. Ventilator associated Pneumonia 1) Documentation of Ventilator associated Pneumonia As with all procedural or postprocedural complications, code assignment is based on the provider’s documentation of the relationship between the condition and the procedure. Code J95.851, Ventilator associated pneumonia, should be assigned only when the provider has documented ventilator associated pneumonia (VAP). An additional code to identify the organism (e.g., Pseudomonas aeruginosa, code B96.5) should also be assigned. Do not assign an additional code from categories J12-J18 to identify the type of pneumonia. Code J95.851 should not be assigned for cases where the patient has pneumonia and is on a mechanical ventilator and the provider has not specifically stated that the pneumonia is ventilator-associated pneumonia. If the documentation is unclear as to whether the patient has a pneumonia that is a complication attributable to the mechanical ventilator, query the provider.
