About coding hematologic shock
The ICD-10-CM code for hematologic shock is R57.8 (Other shock).
Within R57, choose R57.8 (Other shock) only when documentation doesn't support a more specific option: cardiogenic shock (R57.0), Hypovolemic shock (R57.1) and shock, unspecified (R57.9).
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 870 (Septicemia or Severe Sepsis with MV >96 Hours, relative weight 6.9408), DRG 871 (Septicemia or Severe Sepsis without MV >96 Hours with MCC, relative weight 1.932) and DRG 872 (Septicemia or Severe Sepsis without MV >96 Hours without MCC, relative weight 1.0066), in MDC 18 (Infectious and Parasitic Diseases, Systemic or Unspecified Sites), as a principal or secondary diagnosis. The DRG a claim lands in depends on the principal diagnosis, procedures and any CC/MCC secondary diagnoses.
