Oth intraop cardiac functn disturb during cardiac surgery

This code signifies an abnormal cardiac function that develops during a cardiac surgical procedure, but is not specifically a postprocedural cardiac arrest or myocardial infarction. It encompasses a range of intraoperative cardiac issues such as arrhythmias, heart failure, or significant hemodynamic instability that arise during the operation itself.

Apply this code when documentation clearly indicates a new onset or worsening of a cardiac functional disturbance occurring during a cardiac surgical intervention. Examples include new-onset atrial fibrillation, ventricular tachycardia, or acute decompensated heart failure observed on the operating table, provided it's not a postprocedural event. The physician's operative report or anesthesia record should detail the specific cardiac event and its intraoperative timing.

• Ensure the documentation specifies "intraoperative" and "cardiac surgery" to differentiate from postprocedural complications or non-cardiac surgeries.
• Do not use for cardiac arrest (I97.710) or myocardial infarction (I97.720) occurring intraoperatively, as these have more specific codes.
• Always sequence this code after the code for the underlying cardiac surgery or the primary reason for the admission.
