ICD-10 Code I97.71 – Intraoperative cardiac arrest (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I97.71 – Intraoperative cardiac arrest
What it is
I97.71 identifies cardiac arrest that occurs during a surgical procedure. Use it when the arrest happens intraoperatively and is documented as such by the provider.
Clinical signs
Typical findings include sudden loss of pulse, collapse of circulation, and need for immediate resuscitation during the operation. Clinical features vary; refer to documentation.
When to use this code
Use this code when the operative record or postoperative note clearly states intraoperative cardiac arrest. It applies to the event itself, not to routine perioperative monitoring concerns. If the documentation does not specify timing or cause, check documentation before assigning the code.
Do not use for
Do not use I97.71 for cardiac arrest that occurs before anesthesia induction or after surgery unless the provider documents it as intraoperative. Do not use it for unrelated postoperative complications.
Coding tip
Confirm the arrest occurred during the procedure and that the documentation supports a true intraoperative event before coding I97.71.
