ICD-10 Code I97.12 – Postprocedural cardiac arrest (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I97.12 – Postprocedural cardiac arrest
What it is
I97.12 identifies cardiac arrest that occurs after a procedure or surgery. Use it when the arrest is documented as a postoperative or postprocedural complication rather than a preexisting cardiac event.
Clinical signs
Clinical features vary; refer to documentation. Typical records describe sudden loss of pulse, unresponsiveness, and need for resuscitation after a procedure, with the event linked to the intervention.
When to use this code
Use I97.12 when the provider clearly states that cardiac arrest was caused by, or occurred as a complication of, a procedure. You may also use it when the note identifies a postprocedural arrest without another more specific complication code.
Check documentation for the relationship to the procedure and for any additional complication codes that may be required. Code the underlying condition only if it is separately documented and relevant.
Do not use for
Do not use this code for cardiac arrest present before the procedure or for arrest unrelated to the intervention. If the record does not link the event to a procedure, check documentation.
Coding tip
Confirm the operative or procedural note and the complication statement before assigning I97.12.
