Final answer:
Codes from category I97 are reported when there are complications or disorders that arise during or after a procedure that specifically involve the circulatory system.

Step-by-step explanation:
Codes from category I97 Intraoperative and post procedural complications and disorders of circulatory system, not elsewhere classified are reported when there are complications or disorders that arise during or after a procedure that specifically involve the circulatory system. These codes are used to document and track the occurrence of any adverse events or complications that may arise during medical procedures that affect the circulatory system.
For example, if a patient develops a myocardial infarction (heart attack) during or after a surgical procedure, a code from category I97 can be used to indicate this complication. Similarly, if a patient experiences a blood clot or hemorrhage during a surgical procedure that affects the circulatory system, a code from this category can be used to document the complication.
