ICD-10 Code E36.02 – Intraoperative hemorrhage and hematoma of an endocrine system organ or structure complicating other procedure (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code E36.02 – Intraoperative hemorrhage and hematoma of an endocrine system organ or structure complicating other procedure
What it is
This code identifies bleeding or a hematoma that occurs during a procedure and affects an endocrine organ or structure. It is used when the complication is specifically documented as intraoperative and procedure-related.
Clinical signs
Clinical features vary; refer to documentation. Evidence may include operative note descriptions of unexpected bleeding, hematoma formation, or the need for hemostatic measures involving an endocrine gland or related structure.
When to use this code
Use this code when the surgeon documents intraoperative hemorrhage or hematoma involving an endocrine system organ or structure as a complication of another procedure. It fits cases where the bleeding occurred during surgery, not before or after the operation.
Assign it only when the record clearly links the event to the procedure and identifies the endocrine site involved. Check documentation if the note does not specify timing, site, or complication status.
Do not use for
Do not use this code for postoperative bleeding, unrelated spontaneous hemorrhage, or a hematoma that is not documented as an operative complication. Check documentation if the endocrine organ or intraoperative timing is unclear.
Coding tip
Look for explicit language such as “intraoperative hemorrhage” or “hematoma complicating procedure” before assigning E36.02.
