03503ZZ ICD-10-PCS Code: Destruction of Right Internal Mammary Artery, Percutaneous 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 04 — Major Chest Procedures: DRG 163, DRG 164, DRG 165
• MDC 05 — Other Major Cardiovascular Procedures: DRG 270, DRG 271, DRG 272

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