About coding ventilator lung
The ICD-10-CM code for ventilator lung is P27.8 (Other chronic respiratory diseases originating in the perinatal period).
Within P27, choose P27.8 (Other chronic respiratory diseases originating in the perinatal period) only when documentation doesn't support a more specific option: Wilson-Mikity syndrome (P27.0), bronchopulmonary dysplasia originating in the perinatal period (P27.1) and unspecified chronic respiratory disease originating in the perinatal period (P27.9).
As a secondary diagnosis it is an MCC (major complication or comorbidity), which can move an inpatient stay into the highest-paying "with MCC" 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 196 (Interstitial Lung Disease with MCC, relative weight 1.8336), DRG 197 (Interstitial Lung Disease with CC, relative weight 0.9492) and DRG 198 (Interstitial Lung Disease without CC/MCC, relative weight 0.7259), in MDC 04 (Diseases and Disorders of the Respiratory System), as a principal or secondary diagnosis. The DRG a claim lands in depends on the principal diagnosis, procedures and any CC/MCC secondary diagnoses.
