About I97
I97 is the ICD-10-CM diagnosis code for intraoperative and postprocedural complications and disorders of circulatory system, not elsewhere classified. It belongs to block I95-I99 (other and unspecified disorders of the circulatory system) and chapter 9 (diseases of the circulatory system). It is a header code, so it can't be reported by itself; one of its 9 subcodes must be used instead.
To report this condition, pick the subcode that matches the documentation: I97.0 (syndrome), I97.1 (disturbances), I97.2 (syndrome), I97.3 (hypertension), I97.4 (procedure), I97.5 (procedure), I97.6 (procedure), I97.7 (disturbances) and 1 more.
The conditions in its Excludes2 note aren't part of I97, but may be coded alongside it if the patient has both: postprocedural shock (T81.1-).
It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
