About coding cardiogenic shock
The ICD-10-CM code for cardiogenic shock is R57.0 (Cardiogenic shock).
Within R57 (shock, not elsewhere classified), R57.0 is specifically for cardiogenic shock. Related codes cover Hypovolemic shock (R57.1), other shock (R57.8) and shock, unspecified (R57.9).
The conditions in its Excludes2 note aren't part of R57.0, but may be coded alongside it if the patient has both: septic shock (R65.21).
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.
