ICD-10 Code I97.190 – Other postprocedural cardiac functional disturbances following cardiac surgery (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I97.190 – Other postprocedural cardiac functional disturbances following cardiac surgery
What it is
This code identifies cardiac functional problems that occur after cardiac surgery and do not fit a more specific postprocedural complication code. It reflects an abnormal postoperative cardiac function issue, not a routine recovery finding.
Clinical signs
Clinical features vary; refer to documentation. You may see postoperative cardiac dysfunction noted by the surgeon, cardiology, or discharge summary when the problem is described as a functional disturbance after surgery.
When to use this code
Use I97.190 when the record clearly links the cardiac functional disturbance to prior cardiac surgery and no more specific code applies. It is appropriate for documented postoperative dysfunction that is not better classified elsewhere. Check documentation for the exact complication wording and timing.
Do not use for
Do not use this code for routine postoperative pain, expected recovery findings, or unrelated chronic heart disease. If the chart describes a more specific postprocedural cardiac complication, code that condition instead.
Coding tip
Coder tip: confirm the provider explicitly connects the cardiac disturbance to the surgery before assigning I97.190.
