About coding kidney donor
The ICD-10-CM code for kidney donor is Z52.4 (Kidney donor).
Within Z52 (donors of organs and tissues), Z52.4 is specifically for kidney donor. Related codes cover blood donor (Z52.0), skin donor (Z52.1), bone donor (Z52.2), bone marrow donor (Z52.3), cornea donor (Z52.5), liver donor (Z52.6), donor of other specified organs or tissues (Z52.8) and donor of unspecified organ or tissue (Z52.9).
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 698 (Other Kidney and Urinary Tract Diagnoses with MCC, relative weight 1.6398), DRG 699 (Other Kidney and Urinary Tract Diagnoses with CC, relative weight 1.0003) and DRG 700 (Other Kidney and Urinary Tract Diagnoses without CC/MCC, relative weight 0.6741), in MDC 11 (Diseases and Disorders of the Kidney and Urinary Tract), as a principal or secondary diagnosis. The DRG a claim lands in depends on the principal diagnosis, procedures and any CC/MCC secondary diagnoses.
