ICD-10 Code I97.11 – Postprocedural cardiac insufficiency (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I97.11 – Postprocedural cardiac insufficiency
What it is
I97.11 identifies cardiac insufficiency that develops after a procedure. Use it when the chart documents new or worsened heart failure or inadequate cardiac function as a postoperative complication.
Clinical signs
Clinical features vary; refer to documentation. Commonly, records may describe dyspnea, fatigue, fluid retention, reduced cardiac output, or signs of heart failure occurring after surgery or another procedure.
When to use this code
Use I97.11 when the provider clearly links cardiac insufficiency to a prior procedure and documents it as a postoperative complication. It is appropriate when the condition is not simply expected recovery or a preexisting heart problem. Check documentation for timing and causal wording.
Do not use for
Do not use this code for chronic heart failure, nonspecific postoperative weakness, or cardiac symptoms without a documented procedural cause. If the record does not support a postprocedural complication, check documentation.
Coding tip
Confirm that the provider explicitly states the insufficiency is postprocedural before assigning I97.11.
