From the official ICD-10-CM alphabetic index entry “Donor (organ or tissue)”. Page updated September 29, 2026.
About coding donor
The ICD-10-CM code for donor is Z52.9 (Donor of unspecified organ or tissue). The official index lists 32 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on Z52.9.
Within Z52, choose Z52.9 (Donor of unspecified organ or tissue) only when documentation doesn't support a more specific option: blood donor (Z52.0), skin donor (Z52.1), bone donor (Z52.2), bone marrow donor (Z52.3), kidney donor (Z52.4), cornea donor (Z52.5), liver donor (Z52.6) and donor of other specified organs or tissues (Z52.8).
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.
