About coding ventilator status
The ICD-10-CM code for ventilator status is Z99.11 (Dependence on respirator [ventilator] status).
Within Z99.1 (dependence on respirator), Z99.11 is specifically for dependence on respirator [ventilator] status. Related codes cover 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.
