ICD-10 Code I97.4 – Intraoperative hemorrhage and hematoma of a circulatory system organ or structure complicating a procedure (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I97.4 – Intraoperative hemorrhage and hematoma of a circulatory system organ or structure complicating a procedure
What it is
I97.4 identifies bleeding or hematoma involving a circulatory system organ or structure that occurs during a procedure. Use it when the complication is documented as intraoperative and linked to the procedure.
Clinical signs
Clinical features vary; refer to documentation. Commonly, the operative note describes unexpected bleeding, hematoma formation, or the need for additional hemostasis during the procedure.
When to use this code
Use this code when the provider documents intraoperative hemorrhage or hematoma affecting a blood vessel, heart, or other circulatory structure as a procedural complication. It should support a clear cause-and-effect link to the procedure. Check documentation if the record only mentions postoperative bleeding or an unspecified complication.
Do not use for
Do not use I97.4 for bleeding that is unrelated to a procedure, or when the complication is documented as postoperative rather than intraoperative. Do not assign it if the record does not identify a circulatory system organ or structure.
Coding tip
Code the complication only when the operative documentation clearly states the timing and the affected circulatory structure.
