ICD-10 Code E89.810 – Postprocedural hemorrhage of an endocrine system organ or structure following an endocrine system procedure (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code E89.810 – Postprocedural hemorrhage of an endocrine system organ or structure following an endocrine system procedure
What it is
E89.810 identifies bleeding that occurs after a procedure on an endocrine organ or structure, such as the thyroid, parathyroid, adrenal gland, or pituitary. Use it when the hemorrhage is documented as a postoperative complication.
Clinical signs
Clinical features vary; refer to documentation. Commonly, the record may describe postoperative bleeding, hematoma, wound drainage, swelling, or a need for re-exploration after an endocrine procedure.
When to use this code
Use this code when the provider documents hemorrhage as a complication of an endocrine system procedure, not as an expected part of recovery. It applies when the bleeding is clearly linked to the prior operation and the affected endocrine organ or structure is identified. Check documentation if the note does not specify the relationship.
Do not use for
Do not use this code for bleeding unrelated to a procedure, or when the source is not an endocrine organ or structure. Do not assign it if the record only mentions routine postoperative drainage without hemorrhage.
Coding tip
Confirm both the endocrine procedure and the postoperative hemorrhage are documented before assigning E89.810.
