ICD-10 Code E36.0 – Intraoperative hemorrhage and hematoma of an endocrine system organ or structure complicating a procedure (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code E36.0 – Intraoperative hemorrhage and hematoma of an endocrine system organ or structure complicating a procedure
What it is
This code identifies bleeding or a hematoma that occurs during a procedure involving an endocrine organ or structure. It is used when the complication happens intraoperatively and is documented as procedure-related.
Clinical signs
Findings may include unexpected operative bleeding, visible hematoma, or the need for additional hemostasis during surgery. Clinical features vary; refer to documentation.
When to use this code
Use E36.0 when the operative note states that an endocrine organ or structure bled or developed a hematoma during the procedure. The complication should be clearly linked to the surgery, not to a preexisting condition. Check documentation if the record does not specify the site or timing.
Do not use for
Do not use this code for postoperative hemorrhage, accidental injury, or bleeding unrelated to an endocrine procedure. Check documentation when the note only says “bleeding” without identifying an intraoperative complication.
Coding tip
Assign E36.0 only when the surgeon documents an intraoperative complication involving an endocrine organ or structure.
