027G4DZ

Potential MS-DRG Relationships (FY2026)

The MS-DRG grouper treats this as an operating room procedure. It appears in the surgical logic of 4 MS-DRGs:

• MDC 05 — : DRG 231, DRG 232
• MDC 05 — Percutaneous and Other Intracardiac Procedures: DRG 273, DRG 274

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