I97.71Intraoperative cardiac arrest

I97.71 is the ICD-10-CM diagnosis code for intraoperative cardiac arrest. It belongs to category I97 (intraoperative and postprocedural complications and disorders of circulatory system, not elsewhere classified), 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 2 subcodes must be used instead.

Within I97.7 (intraoperative cardiac functional disturbances), I97.71 is specifically for intraoperative cardiac arrest. Related codes cover other intraoperative cardiac functional disturbances (I97.79).

To report this condition, pick the subcode that matches the documentation: I97.710 (during cardiac surgery) and I97.711 (during other surgery).

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