ICD-10 Code I97.611 – Postprocedural hemorrhage of a circulatory system organ or structure following cardiac bypass (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I97.611 – Postprocedural hemorrhage of a circulatory system organ or structure following cardiac bypass
What it is
I97.611 identifies bleeding that occurs after a cardiac bypass procedure and is considered a postprocedural complication. Use it when the hemorrhage is documented as related to the bypass surgery, not as routine expected postoperative drainage.
Clinical signs
Clinical features vary; refer to documentation. Typical signs may include documented postoperative bleeding, expanding hematoma, or need for evaluation because of suspected hemorrhage after cardiac bypass.
When to use this code
Use this code when the record clearly states hemorrhage occurred after cardiac bypass and the provider links it to the procedure. It applies to postoperative bleeding from a circulatory system organ or structure, including graft or surgical site bleeding, when documented as a complication. Check documentation if the note only mentions anemia, drainage, or blood loss without stating hemorrhage.
Do not use for
Do not use it for routine postoperative drainage, expected blood loss, or hemorrhage unrelated to the bypass procedure. If the bleeding source or cause is unclear, check documentation.
Coding tip
Confirm the provider documents a causal link between the hemorrhage and cardiac bypass before assigning I97.611.
