ICD-10 Code I97.411 – Intraoperative hemorrhage and hematoma of a circulatory system organ or structure complicating a cardiac bypass (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I97.411 – Intraoperative hemorrhage and hematoma of a circulatory system organ or structure complicating a cardiac bypass
What it is
This code identifies bleeding or a blood collection that occurs during cardiac bypass surgery and affects a circulatory system organ or structure. Use it when the operative report documents the complication as intraoperative.
Clinical signs
Findings may include unexpected surgical bleeding, hematoma formation, or the need for additional hemostasis during the bypass procedure. Clinical features vary; refer to documentation.
When to use this code
Use I97.411 when the surgeon documents an intraoperative hemorrhage or hematoma as a complication of cardiac bypass surgery. The record should link the event to the bypass procedure, not to a preexisting condition or a postoperative complication.
If the note only says bleeding occurred without specifying timing or relationship to bypass surgery, check documentation. Code the complication only when the operative or progress note clearly supports it.
Do not use for
Do not use this code for postoperative bleeding, routine expected blood loss, or hemorrhage unrelated to cardiac bypass. Check documentation if the site, timing, or procedure relationship is unclear.
Coding tip
Look for explicit wording such as “intraoperative” and “complicating cardiac bypass” before assigning this code.
