ICD-10 Code E89.820 – Postprocedural hematoma of an endocrine system organ or structure following an endocrine system procedure (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code E89.820 – Postprocedural hematoma of an endocrine system organ or structure following an endocrine system procedure
What it is
This code identifies a hematoma that develops in an endocrine organ or related structure after an endocrine procedure. It indicates a postprocedural bleeding complication, not the underlying endocrine disease.
Clinical signs
Clinical features vary; refer to documentation. You may see localized swelling, pain, bruising, or evidence of bleeding at the operative site, with imaging or operative notes confirming a hematoma.
When to use this code
Use this code when the record states that a hematoma occurred after a procedure involving an endocrine system organ or structure, such as surgery or another intervention. Code it when the provider documents the complication as postprocedural and links it to the endocrine procedure. Check documentation if the site or causal relationship is unclear.
Do not use for
Do not use this code for a pre-existing hematoma, traumatic bleeding, or a hematoma unrelated to a procedure. If the note does not specify an endocrine system procedure or does not identify the complication as postprocedural, check documentation.
Coding tip
Verify both the endocrine site and the postprocedural relationship in the operative or progress note before assigning E89.820.
