ICD-10 code for transplant
From the official ICD-10-CM alphabetic index entry “Transplant (ed) (status)”. Page updated September 29, 2026.
About coding transplant
The ICD-10-CM code for transplant is Z94.9 (Transplanted organ and tissue status, unspecified). The official index lists 24 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on Z94.9.
Within Z94, choose Z94.9 (unspecified) only when documentation doesn't support a more specific option: kidney transplant status (Z94.0), heart transplant status (Z94.1), lung transplant status (Z94.2), heart and lungs transplant status (Z94.3), liver transplant status (Z94.4), skin transplant status (Z94.5), bone transplant status (Z94.6), corneal transplant status (Z94.7) and 1 more.
It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.
In MS-DRG v44.0, it is part of the grouping logic for DRG 951 (Other Factors Influencing Health Status, relative weight 0.5577), in MDC 23 (Factors Influencing Health Status and Other Contacts with Health Services), as a principal or secondary diagnosis. The DRG a claim lands in depends on the principal diagnosis, procedures and any CC/MCC secondary diagnoses.
