About Z98

Z98 is the ICD-10-CM diagnosis code for other postprocedural states. 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 8 subcodes must be used instead.

To report this condition, pick the subcode that matches the documentation: Z98.0 (status), Z98.1 (status), Z98.2 (device), Z98.3 (status), Z98.4 (status), Z98.5 (status), Z98.6 (status) and Z98.8 (states).

The conditions in its Excludes2 note aren't part of Z98, but may be coded alongside it if the patient has both: aftercare (Z43-Z49, Z51), follow-up medical care (Z08-Z09), Fontan related circulation (I27.84-) and postprocedural complication - see Alphabetical Index.

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