About coding cornea donor
The ICD-10-CM code for cornea donor is Z52.5 (Cornea donor).
Within Z52 (donors of organs and tissues), Z52.5 is specifically for cornea donor. Related codes cover blood donor (Z52.0), skin donor (Z52.1), bone donor (Z52.2), bone marrow donor (Z52.3), kidney donor (Z52.4), 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 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.
