ICD-10 Code I97.42 – Intraoperative hemorrhage and hematoma of a circulatory system organ or structure complicating other procedure (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I97.42 – Intraoperative hemorrhage and hematoma of a circulatory system organ or structure complicating other procedure
What it is
This code identifies bleeding or a hematoma that occurs during a procedure and involves a circulatory system organ or structure. Use it when the complication is specifically documented as intraoperative and procedure-related.
Clinical signs
Clinical features vary; refer to documentation. Typical findings include unexpected bleeding, visible hematoma, or operative note confirmation of vessel or cardiovascular structure injury during the procedure.
When to use this code
Use I97.42 when the provider documents an intraoperative hemorrhage or hematoma affecting a circulatory system organ or structure as a complication of another procedure. The record should link the event to the procedure, not to a preexisting condition. Check documentation if the note only describes postoperative bleeding or an unspecified surgical complication.
Do not use for
Do not use this code for routine blood loss, postoperative hemorrhage, or bleeding unrelated to a procedure. It is also not appropriate when the affected structure is not part of the circulatory system.
Coding tip
Verify the operative report for both the timing and the anatomic site before assigning I97.42.
