ICD-10 Code I97.111 – Postprocedural cardiac insufficiency following other surgery (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I97.111 – Postprocedural cardiac insufficiency following other surgery
What it is
I97.111 identifies cardiac insufficiency that develops after a surgical procedure other than cardiac surgery. Use it when documentation shows new or worsened heart weakness is attributed to the operation.
Clinical signs
Clinical features may include postoperative dyspnea, fatigue, edema, or signs of reduced cardiac output. Clinical features vary; refer to documentation for the provider’s stated diagnosis and postoperative relationship.
When to use this code
Use this code when the record clearly links cardiac insufficiency to a recent noncardiac surgery and the provider documents it as postoperative or postprocedural. It is appropriate for complications described as occurring after the procedure, not for longstanding heart disease. If the relationship is unclear, check documentation before assigning the code.
Do not use for
Do not use it for preexisting heart failure, routine postoperative monitoring, or cardiac conditions unrelated to surgery. Check documentation if the note does not state a postprocedural cause.
Coding tip
Code the postprocedural complication only when the provider explicitly connects the cardiac insufficiency to the surgery.
