Intraoperative and postprocedural complications and disorders of circulatory system, not elsewhere classified (I97) ICD-10-CM
The I97 code range covers intraoperative and postprocedural complications and disorders of circulatory system, not elsewhere classified with 59 ICD-10-CM diagnosis codes. 39 of them are billable and valid for claim submission in fiscal year 2027, and the category headers group them but cannot themselves be billed.
Type 2 Excludes
A type 2 excludes note represents "Not included here". An excludes2 note indicates that the condition excluded is not part of the condition represented by the code, but a patient may have both conditions at the same time. When an Excludes2 note appears under a code, it is acceptable to use both the code and the excluded code together, when appropriate.

About the I97 Code Range
Problems affecting the heart and blood vessels can occur during a procedure or afterward. This category separates those problems by what happened and, for some conditions, by the type of procedure.
I97.1 groups heart function problems after a procedure, including cardiac arrest and heart failure. I97.7 groups heart function problems during a procedure. Their subdivisions distinguish cardiac surgery from other surgery.
I97.4 addresses bleeding or a collection of blood during a procedure; I97.5 addresses accidental punctures or cuts. I97.6 separates bleeding, collections of blood, and collections of fluid after a procedure. These subdivisions also distinguish circulatory system procedures from other procedures, with further distinctions for cardiac catheterization and bypass. Other branches identify swelling after mastectomy, high blood pressure after a procedure, and other circulatory system complications.
