ICD-10 Code I97.710 – Intraoperative cardiac arrest during cardiac surgery (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I97.710 – Intraoperative cardiac arrest during cardiac surgery
What it is
This code identifies a cardiac arrest that occurs during a cardiac surgery procedure. Use it when the arrest is documented as happening intraoperatively and specifically tied to cardiac surgery.
Clinical signs
Clinical features vary; refer to documentation. Typical evidence includes sudden loss of pulse, loss of circulation, and the need for immediate resuscitative measures while the patient is in the operating room.
When to use this code
Use I97.710 when the operative note or perioperative record clearly states intraoperative cardiac arrest during cardiac surgery. It is appropriate when the event is documented as a complication of the procedure, not as a preexisting condition.
If the record only says “cardiac arrest” without timing or surgical context, check documentation before assigning this code. Verify that the arrest occurred during the cardiac surgery itself.
Do not use for
Do not use this code for cardiac arrest that occurs before surgery, after surgery, or during non-cardiac procedures. Check documentation if the arrest is unrelated to the operative event.
Coding tip
Confirm both timing and procedure type in the operative report before coding I97.710.
