03RN47Z ICD-10-PCS Code: Replacement of Left External Carotid Artery with Autologous 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 6 MS-DRGs:

• MDC 01 — Peripheral, Cranial Nerve and Other Nervous System Procedures: DRG 040, DRG 041, DRG 042
• MDC 05 — Other Vascular Procedures: DRG 252, DRG 253, DRG 254

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