About I97.8
I97.8 is the ICD-10-CM diagnosis code for other intraoperative and postprocedural complications and disorders of the circulatory system, not elsewhere classified. 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 4 subcodes must be used instead.
Within I97, choose I97.8 (Other intraoperative and postprocedural complications and disorders of the circulatory system, not elsewhere classified) only when documentation doesn't support a more specific option: 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 intraoperative cardiac functional disturbances (I97.7).
To report this condition, pick the subcode that matches the documentation: I97.81 (infarction), I97.82 (infarction), I97.88 (classified) and I97.89 (classified).
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.
