About coding circulatory peripheral collapse
The ICD-10-CM code for circulatory peripheral collapse is R57.9 (Shock, unspecified). The official index lists 3 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on R57.9.
Within R57, choose R57.9 (Shock, unspecified) only when documentation doesn't support a more specific option: cardiogenic shock (R57.0), Hypovolemic shock (R57.1) and other shock (R57.8).
As a secondary diagnosis it is a CC (complication or comorbidity), which can move an inpatient stay into the "with CC" 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), DRG 293 (Heart Failure and Shock without CC/MCC, relative weight 0.5462), DRG 791 (Prematurity with Major Problems, relative weight 4.1075) and DRG 793 (Full Term Neonate with Major Problems, relative weight 4.2195), in MDC 05 (Diseases and Disorders of the Circulatory System) and MDC 15 (Newborns and Other Neonates with Conditions Originating in the Perinatal Period), as a principal or secondary diagnosis. The DRG a claim lands in depends on the principal diagnosis, procedures and any CC/MCC secondary diagnoses.
