R57.0Cardiogenic shock

R57.0 is the ICD-10-CM diagnosis code for cardiogenic shock. It belongs to category R57 (shock, not elsewhere classified), block R50-R69 (general symptoms and signs) and chapter 18 (symptoms, signs and abnormal clinical and laboratory findings, not elsewhere classified). It is billable, so it can be reported on its own for dates of service from October 1, 2026 through September 30, 2027.

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.

In MS-DRG v44.0, it is part of the grouping logic for DRG 291 (Heart Failure and Shock with MCC, relative weight 1.2685), DRG 292 (Heart Failure and Shock with CC, relative weight 0.8616) and DRG 293 (Heart Failure and Shock without CC/MCC, relative weight 0.5462), in MDC 05 (Diseases and Disorders of the Circulatory 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.

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 785.51 (cardiogenic shock).
