ICD-10 Code E36.8 – Other intraoperative complications of endocrine system (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code E36.8 – Other intraoperative complications of endocrine system
What it is
This code identifies an unexpected complication affecting the endocrine system that occurs during surgery or another operative procedure. Use it when the record describes an intraoperative endocrine complication not named by a more specific code.
Clinical signs
Clinical features vary; refer to documentation. The operative note may describe endocrine tissue injury, disruption, or another complication recognized during the procedure.
When to use this code
Use E36.8 when the surgeon documents a complication involving the endocrine system that happens during the operation and no more specific ICD-10-CM code fits. You should code it from the operative report or discharge summary when the complication is clearly linked to the intraoperative period.
If the documentation only says “complication” without identifying the endocrine system, check documentation before assigning this code. Do not infer the diagnosis from postoperative findings alone unless the record clearly supports an intraoperative event.
Do not use for
Do not use this code for postoperative endocrine complications or for routine endocrine disease unrelated to surgery. Check documentation if the complication is better captured by another, more specific code.
Coding tip
Link the code to the intraoperative event and verify that the endocrine system is specifically identified in the record.
