02RK4KZ ICD-10-PCS Code: Replacement of Right Ventricle with Nonautologous Tissue Substitute, Percutaneous Endoscopic Approach

MS-DRG Grouper Relationships (FY2026)

Potential MS-DRG participation — not a DRG assignment.

The MS-DRG grouper treats this as an operating room procedure. It appears in the surgical logic of 2 MS-DRGs:

• MDC 05 — Other Cardiothoracic Procedures: DRG 228, DRG 229

From the CMS MS-DRG Definitions Manual, Appendix E. Actual DRG assignment depends on the complete claim.
