About Z52.00
Z52.00 is the ICD-10-CM diagnosis code for unspecified blood donor. It belongs to category Z52 (donors of organs and tissues), block Z40-Z53 (Encounters for other specific health care) and chapter 21 (factors influencing health status and contact with health services). It is a header code, so it can't be reported by itself; one of its 3 subcodes must be used instead.
Within Z52.0, choose Z52.00 (Unspecified blood donor) only when documentation doesn't support a more specific option: autologous blood donor (Z52.01) and other blood donor (Z52.09).
To report this condition, pick the subcode that matches the documentation: Z52.000 (blood), Z52.001 (cells) and Z52.008 (blood).
It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
