ICD-10 Code E89.821 – Postprocedural hematoma of an endocrine system organ or structure following other procedure (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code E89.821 – Postprocedural hematoma of an endocrine system organ or structure following other procedure
What it is
This code identifies a hematoma that develops in an endocrine organ or related structure after a procedure. It reflects a postoperative bleeding complication, not the original endocrine disease.
Clinical signs
Clinical features vary; refer to documentation. Commonly, the record may describe swelling, pain, bruising, or a postoperative collection confirmed by imaging or exam in the endocrine operative site.
When to use this code
Use this code when the provider documents a hematoma involving an endocrine system organ or structure as a direct result of a procedure. It applies when the complication is clearly postoperative and not simply expected surgical bruising. Check documentation for the specific endocrine site and procedure context.
Do not use for
Do not use this code for preexisting hematomas, nonsurgical bleeding, or hematomas in non-endocrine sites. If the record does not link the hematoma to a procedure, check documentation.
Coding tip
Assign the postoperative complication code only when the provider explicitly documents the hematoma as procedure-related.
