J95.851Ventilator associated pneumonia

J95.851 is the ICD-10-CM diagnosis code for ventilator associated pneumonia. It belongs to category J95 (intraoperative and postprocedural complications and disorders of respiratory system, not elsewhere classified), block J95 (intraoperative and postprocedural complications and disorders of respiratory system, not elsewhere classified) and chapter 10 (diseases of the respiratory system). It is billable, so it can be reported on its own for dates of service from October 1, 2026 through September 30, 2027.

Within J95.85 (complication of respirator [ventilator]), J95.851 is specifically for ventilator associated pneumonia. Related codes cover mechanical complication of respirator (J95.850) and other complication of respirator [ventilator] (J95.859).

Don't report J95.851 together with the conditions in its Excludes1 note: ventilator lung in newborn (P27.8).

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

As a secondary diagnosis it is a CC (complication or comorbidity), which can move an inpatient stay into the "with CC" MS-DRG of its family, unless the principal diagnosis excludes it.

In MS-DRG v44.0, it is part of the grouping logic for DRG 205 (Other Respiratory System Diagnoses with MCC, relative weight 1.8244), DRG 206 (Other Respiratory System Diagnoses without MCC, relative weight 0.9257), DRG 791 (Prematurity with Major Problems, relative weight 4.1075) and DRG 793 (Full Term Neonate with Major Problems, relative weight 4.2195), in MDC 04 (Diseases and Disorders of the Respiratory System) and MDC 15 (Newborns and Other Neonates with Conditions Originating in the Perinatal Period), as a principal or secondary diagnosis. The DRG a claim lands in depends on the principal diagnosis, procedures and any CC/MCC secondary diagnoses.

It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.

Before ICD-10, this condition was coded in ICD-9-CM as 997.31 (ventilator associated pneumonia).
