I97.79Other intraoperative cardiac functional disturbances

I97.79 is the ICD-10-CM diagnosis code for other intraoperative cardiac functional disturbances. 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, choose I97.79 (Other intraoperative cardiac functional disturbances) only when documentation doesn't support a more specific option: intraoperative cardiac arrest (I97.71).

To report this condition, pick the subcode that matches the documentation: I97.790 (during cardiac surgery) and I97.791 (during other surgery).

Use an additional code, if applicable, to further specify disorder.

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