About J95.850
J95.850 is the ICD-10-CM diagnosis code for mechanical complication of respirator. 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]), J95.850 is specifically for mechanical complication of respirator. Related codes cover ventilator associated pneumonia (J95.851) and other complication of respirator [ventilator] (J95.859).
Don't report J95.850 together with the conditions in its Excludes1 note: encounter for respirator [ventilator] dependence during power failure (Z99.12).
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 951 (Other Factors Influencing Health Status, relative weight 0.5577), in MDC 23 (Factors Influencing Health Status and Other Contacts with Health Services), 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 V46.14 (mechanical complication of respirator [ventilator]).
