About coding mitral valve rupture
The ICD-10-CM code for mitral valve rupture is I34.89 (Other nonrheumatic mitral valve disorders).
Within I34.8, choose I34.89 (Other nonrheumatic mitral valve disorders) only when documentation doesn't support a more specific option: nonrheumatic mitral (valve) annulus calcification (I34.81).
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 306 (Cardiac Congenital and Valvular Disorders with MCC, relative weight 1.546) and DRG 307 (Cardiac Congenital and Valvular Disorders without MCC, relative weight 0.9148), 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.
