ICD-10 code for Postcardiac surgery syndrome injury

The ICD-10-CM code for Postcardiac surgery syndrome injury is I97.0 (Postcardiotomy syndrome).

Within I97 (intraoperative and postprocedural complications and disorders of circulatory system, not elsewhere classified), I97.0 is specifically for Postcardiotomy syndrome. Related codes cover other postprocedural cardiac functional disturbances (I97.1), Postmastectomy lymphedema syndrome (I97.2), postprocedural hypertension (I97.3), intraoperative hemorrhage and hematoma of a circulatory system organ or structure complicating a procedure (I97.4), accidental puncture and laceration of a circulatory system organ or structure during a procedure (I97.5), postprocedural hemorrhage, hematoma and seroma of a circulatory system organ or structure following a procedure (I97.6), intraoperative cardiac functional disturbances (I97.7) and other intraoperative and postprocedural complications and disorders of the circulatory system, not elsewhere classified (I97.8).

It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.

In MS-DRG v44.0, it is part of the grouping logic for DRG 314 (Other Circulatory System Diagnoses with MCC, relative weight 2.0873), DRG 315 (Other Circulatory System Diagnoses with CC, relative weight 0.9508), DRG 316 (Other Circulatory System Diagnoses without CC/MCC, relative weight 0.6677), 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.
