About I97.82

I97.82 is the ICD-10-CM diagnosis code for postprocedural cerebrovascular infarction. 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 I97.8 (other intraoperative and postprocedural complications and disorders of the circulatory system, not elsewhere classified), I97.82 is specifically for postprocedural cerebrovascular infarction. Related codes cover intraoperative cerebrovascular infarction (I97.81), other intraoperative complications of the circulatory system, not elsewhere classified (I97.88) and other postprocedural complications and disorders of the circulatory system, not elsewhere classified (I97.89).

To report this condition, pick the subcode that matches the documentation: I97.820 (following cardiac surgery) and I97.821 (following 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.
