About Z94

Z94 is the ICD-10-CM diagnosis code for transplanted organ and tissue status. It belongs to block Z77-Z99 (persons with potential health hazards related to family and personal history and certain conditions influencing health status) 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 10 subcodes must be used instead.

To report this condition, pick the subcode that matches the documentation: Z94.0 (status), Z94.1 (status), Z94.2 (status), Z94.3 (status), Z94.4 (status), Z94.5 (status), Z94.6 (status), Z94.7 (status) and 2 more.

Don't report Z94 together with the conditions in its Excludes1 note: complications of transplanted organ or tissue - see Alphabetical Index.

The conditions in its Excludes2 note aren't part of Z94, but may be coded alongside it if the patient has both: presence of vascular grafts (Z95.-).

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