2025 ICD-10-CM code I97.7
(Active) Effective Date: N/A Revision Date: N/A Deletion Date: N/A Diseases of the circulatory system - Other intraoperative and postprocedural complications and disorders of the circulatory system, not elsewhere classified Diseases of the circulatory system (I00-I99) Feed
Intraoperative cardiac functional disturbances.
Modifiers may apply depending on the specific circumstances of the procedure and the nature of the intraoperative cardiac event. Consult the official guidelines for modifier usage with I97.7
Medical necessity for coding I97.7 is established by the occurrence of a clinically significant cardiac functional disturbance during a surgical procedure that requires monitoring, intervention, or documentation of the event.The severity of the disturbance, the need for intervention, and the duration of the event help in establishing the clinical significance.
The clinical responsibility for coding I97.7 rests with the surgeon or the cardiologist involved in the procedure.Accurate documentation by both the anesthesiologist and the surgeon is crucial for proper coding.
- Diseases of the circulatory system (I00-I99)
- I97-I99 (Other and unspecified disorders of the circulatory system)
In simple words: This code describes problems with how well the heart is working during an operation.
This code captures cardiac functional disturbances that occur during a surgical procedure.It encompasses a range of disruptions to the heart's function, occurring intraoperatively.The code excludes acute pulmonary insufficiency following thoracic surgery (J95.1), postprocedural cardiac functional disturbances (I97.1-), and postprocedural shock (T81.1-).
Example 1: A patient undergoing coronary artery bypass grafting (CABG) experiences a significant drop in blood pressure and a change in heart rhythm during the procedure. This would be coded as I97.7., During a valve replacement surgery, the patient's heart rate becomes dangerously slow, necessitating immediate intervention.This event would be documented and coded with I97.7., A patient undergoing cardiac catheterization experiences a transient episode of arrhythmia during the procedure that resolves without intervention. This event can be considered for coding under I97.7.
Comprehensive operative notes detailing the intraoperative cardiac event are essential. This includes the nature of the disturbance, the time of occurrence, any interventions taken, and the patient's response to treatment. Anesthesiology records are also important to document vital signs, medications administered, and the overall course of the procedure.
** This code should be used cautiously and only when the cardiac dysfunction is directly related to the surgical procedure.Clinicians should ensure that the documentation clearly supports the diagnosis.
