About coding lung shock
The ICD-10-CM code for lung shock is J80 (Acute respiratory distress syndrome).
Don't report J80 together with the conditions in its Excludes1 note: respiratory distress syndrome in newborn (perinatal) (P22.0).
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 189 (Pulmonary Edema and Respiratory Failure, relative weight 1.2108), 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.
Don't confuse with (Excludes1 for J80)
- respiratory distress syndrome in newborn (perinatal) (P22.0)
