Z94.81 ICD-10-CM Code: Bone marrow transplant status
Billing Status: YES. This is a valid, specific, and billable ICD-10-CM reference.
Inpatient Payment Groups (MS-DRG)
MS-DRGs this diagnosis helps define, as principal or secondary, per the CMS ICD-10-CM/PCS MS-DRG Definitions Manual v43.0 (FY2026), Appendix B.
- MS-DRG 814 — RETICULOENDOTHELIAL AND IMMUNITY DISORDERS WITH MCC (MDC 16)
- MS-DRG 815 — RETICULOENDOTHELIAL AND IMMUNITY DISORDERS WITH CC (MDC 16)
- MS-DRG 816 — RETICULOENDOTHELIAL AND IMMUNITY DISORDERS WITHOUT CC/MCC (MDC 16)
A diagnosis appearing in a group's logic does not by itself determine the DRG assigned to a stay; the grouper uses the full claim.
