01BK0ZX ICD-10-PCS Code: Excision of Head and Neck Sympathetic Nerve, Open Approach, Diagnostic

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 3 MS-DRGs:

• MDC 01 — Peripheral, Cranial Nerve and Other Nervous System Procedures: DRG 040, DRG 041, DRG 042

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