ICD-10 code for cardiac rupture

The ICD-10-CM code for cardiac rupture is I23.3 (Rupture of cardiac wall without hemopericardium as current complication following acute myocardial infarction). The official index lists 2 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on I23.3.

Within I23, choose I23.3 (Rupture of cardiac wall without hemopericardium as current complication following acute myocardial infarction) only when documentation doesn't support a more specific option: hemopericardium as current complication following acute myocardial infarction (I23.0), atrial septal defect as current complication following acute myocardial infarction (I23.1), ventricular septal defect as current complication following acute myocardial infarction (I23.2), rupture of chordae tendineae as current complication following acute myocardial infarction (I23.4), rupture of papillary muscle as current complication following acute myocardial infarction (I23.5), thrombosis of atrium, auricular appendage, and ventricle as current complications following acute myocardial infarction (I23.6), Postinfarction angina (I23.7) and other current complications following acute myocardial infarction (I23.8).

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 314 (Other Circulatory System Diagnoses with MCC, relative weight 2.0873), DRG 315 (Other Circulatory System Diagnoses with CC, relative weight 0.9508) and DRG 316 (Other Circulatory System Diagnoses without CC/MCC, relative weight 0.6677), 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.
