ICD-10 code for mitral valve replacement

The ICD-10-CM code for mitral valve replacement is Z95.2 (Presence of prosthetic heart valve). The official index lists 2 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on Z95.2.

It is also searched as status post mitral valve replacement.

Within Z95 (presence of cardiac and vascular implants and grafts), Z95.2 is specifically for presence of prosthetic heart valve. Related codes cover cardiac pacemaker (Z95.0), aortocoronary bypass graft (Z95.1), xenogenic heart valve (Z95.3), other heart-valve replacement (Z95.4), coronary angioplasty implant and graft (Z95.5), other cardiac and vascular implants and grafts (Z95.8) and cardiac and vascular implant and graft, unspecified (Z95.9).

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) 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.
