ICD-10 Code I97.110 – Postprocedural cardiac insufficiency following cardiac surgery (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I97.110 – Postprocedural cardiac insufficiency following cardiac surgery
What it is
I97.110 identifies cardiac insufficiency that develops after cardiac surgery. Use it when the record states the heart is not pumping adequately as a postoperative complication.
Clinical signs
Clinical features vary; refer to documentation. Typical charted findings may include postoperative low cardiac output, poor perfusion, or heart failure noted after surgery.
When to use this code
Use this code when the provider documents cardiac insufficiency as a direct consequence of cardiac surgery. It applies to postoperative cases where the insufficiency is not merely a preexisting chronic condition.
Code the complication only when the documentation clearly links it to the procedure. If the note is unclear about timing or cause, check documentation before assigning I97.110.
Do not use for
Do not use this code for chronic heart failure, general postoperative weakness, or cardiac problems unrelated to surgery. Check documentation if the record describes another specific postoperative cardiac complication.
Coding tip
Confirm that the surgeon or treating provider explicitly documents the insufficiency as postprocedural and following cardiac surgery.
