ICD-10 Code E36.01 – Intraoperative hemorrhage and hematoma of an endocrine system organ or structure complicating an endocrine system procedure (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code E36.01 – Intraoperative hemorrhage and hematoma of an endocrine system organ or structure complicating an endocrine system procedure
What it is
This code identifies bleeding or hematoma that occurs during an endocrine system procedure and involves an endocrine organ or structure. Use it when the complication is documented as intraoperative and procedure-related.
Clinical signs
Clinical features vary; refer to documentation. Typical findings may include operative bleeding, visible hematoma, or the need for intraoperative control of hemorrhage during surgery on an endocrine organ.
When to use this code
Use this code when the surgeon documents intraoperative hemorrhage or hematoma as a complication of an endocrine procedure. It applies to operative events involving endocrine organs or structures, not to routine expected blood loss. If the record does not clearly state the complication, check documentation.
Do not use for
Do not use this code for postoperative bleeding, nonsurgical endocrine bleeding, or hematoma unrelated to an endocrine procedure. Do not assign it when the complication site or timing is unclear.
Coding tip
Code the complication only when the operative note clearly links the bleeding or hematoma to the endocrine procedure.
