02120J8 ICD-10-PCS Code: Bypass Coronary Artery, Three Arteries from Right Internal Mammary with Synthetic Substitute, Open 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 7 MS-DRGs:

• MDC 05 — Concomitant Aortic and Mitral Valve Procedures: DRG 212
• MDC 05 — : DRG 231, DRG 232, DRG 233, DRG 234
• MDC 05 — Coronary Bypass without Cardiac Catheterization: DRG 235, DRG 236

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