ICD-10 Code E36 – Intraoperative complications of endocrine system (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code E36 – Intraoperative complications of endocrine system
What it is
E36 identifies complications involving the endocrine system that occur during surgery or another operative procedure. Use it when the record documents an intraoperative endocrine complication rather than a preexisting endocrine disorder.
Clinical signs
Clinical features vary; refer to documentation. Notes may describe unexpected endocrine injury, gland dysfunction, or operative disruption of endocrine structures recognized during the procedure.
When to use this code
Use E36 when the surgeon documents an endocrine complication that arose during the operation and is not coded elsewhere. It is appropriate when the complication is clearly linked to the intraoperative period. Check documentation for the exact gland, injury, or operative event.
Do not use for
Do not use this code for routine endocrine disease, postoperative complications, or complications unrelated to surgery. If the record does not confirm an intraoperative endocrine complication, check documentation before assigning E36.
Coding tip
Code the specific complication and sequence any additional codes the chart supports, but only if the documentation clearly states the intraoperative endocrine event.
