- MDC 05 — Other Circulatory System O.R. Procedures: DRG 264
- 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
From the CMS MS-DRG Definitions Manual, Appendix E. Actual DRG assignment depends on the complete claim.
