I97.7Intraoperative cardiac functional disturbances

I97.7 is the ICD-10-CM diagnosis code for 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 (intraoperative and postprocedural complications and disorders of circulatory system, not elsewhere classified), I97.7 is specifically for intraoperative cardiac functional disturbances. Related codes cover Postcardiotomy syndrome (I97.0), other postprocedural cardiac functional disturbances (I97.1), Postmastectomy lymphedema syndrome (I97.2), postprocedural hypertension (I97.3), intraoperative hemorrhage and hematoma of a circulatory system organ or structure complicating a procedure (I97.4), accidental puncture and laceration of a circulatory system organ or structure during a procedure (I97.5), postprocedural hemorrhage, hematoma and seroma of a circulatory system organ or structure following a procedure (I97.6) and other intraoperative and postprocedural complications and disorders of the circulatory system, not elsewhere classified (I97.8).

To report this condition, pick the subcode that matches the documentation: I97.71 (arrest) and I97.79 (disturbances).

The conditions in its Excludes2 note aren't part of I97.7, but may be coded alongside it if the patient has both: acute pulmonary insufficiency following thoracic surgery (J95.1) and postprocedural cardiac functional disturbances (I97.1-).

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