009840ZICD-10-PCS Code: Drainage of Basal Ganglia with Drainage Device, Percutaneous Endoscopic Approach

Potential MS-DRG Relationships (FY2026)

The MS-DRG grouper treats this as an operating room procedure. It appears in the surgical logic of 12 MS-DRGs:

• MDC 01 — Craniotomy with Major Device Implant or Acute Complex CNS Principal Diagnosis: DRG 023, DRG 024
• MDC 01 — Craniotomy and endovascular intracranial procedures: DRG 025, DRG 026, DRG 027
• MDC 17 — Lymphoma and Leukemia with Major O.R. Procedures: DRG 820, DRG 821, DRG 822
• MDC 17 — Myeloproliferative Disorders or Poorly Differentiated Neoplasms with Major O.R. Procedures: DRG 826, DRG 827, DRG 828
• MDC 24 — Craniotomy for Multiple Significant Trauma: DRG 955

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