About Z14

Z14 is the ICD-10-CM diagnosis code for genetic carrier. It belongs to block Z14-Z15 (genetic carrier and genetic susceptibility to disease) 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.

To report this condition, pick the subcode that matches the documentation: Z14.0 (carrier), Z14.1 (carrier) and Z14.8 (of other disease).

It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
