ICD-10 Code E36.11 – Accidental puncture and laceration of an endocrine system organ or structure during an endocrine system procedure (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code E36.11 – Accidental puncture and laceration of an endocrine system organ or structure during an endocrine system procedure
What it is
This code describes an unintended puncture or tear of an endocrine organ or related structure that occurs during an endocrine system procedure. It identifies a procedure complication, not the underlying endocrine disease.
Clinical signs
Clinical features vary; refer to documentation. You may see operative notes describing direct injury, bleeding, repair, or delayed recognition of damage to an endocrine organ or adjacent structure.
When to use this code
Use this code when the record clearly states that an endocrine procedure caused an accidental puncture or laceration. It is appropriate when the complication is documented as occurring intraoperatively or as a direct procedural injury. Code the complication only when the provider links the injury to the procedure.
Do not use for
Do not use this code for expected surgical entry, planned resection, or a preexisting endocrine organ injury. Check documentation if the note does not clearly identify an accidental procedure-related injury.
Coding tip
Look for explicit wording such as “accidental puncture,” “laceration,” or “procedure complication” before assigning E36.11.
