MS-DRG Grouper Relationships (FY2027)
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 24 MS-DRGs:
- MDC 01 — Peripheral, Cranial Nerve and Other Nervous System Procedures: DRG 040, DRG 041, DRG 042
- MDC 04 — Major Chest Procedures: DRG 163, DRG 164, DRG 165
- MDC 10 — Other Endocrine, Nutritional and Metabolic O.R. Procedures: DRG 628, DRG 629, DRG 630
- MDC 16 — Other O.R. Procedures of the Blood and Blood Forming Organs: DRG 802, DRG 803, DRG 804
- 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 21 — Other O.R. Procedures for Injuries: DRG 907, DRG 908, DRG 909
- MDC 24 — Other O.R. Procedures for Multiple Significant Trauma: DRG 957, DRG 958, DRG 959
