ICD-10 Code E89.82 – Postprocedural hematoma and seroma of an endocrine system organ or structure (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code E89.82 – Postprocedural hematoma and seroma of an endocrine system organ or structure
What it is
This code identifies a hematoma or seroma that develops after a procedure involving an endocrine organ or structure. It describes a postoperative collection of blood or fluid, not the original endocrine disease.
Clinical signs
Clinical features vary; refer to documentation. You may see localized swelling, tenderness, bruising, or a fluid collection noted on exam or imaging after surgery.
When to use this code
Use this code when the provider documents a postprocedural hematoma or seroma affecting an endocrine system site, such as after gland surgery. It fits complications clearly linked to the procedure and the endocrine anatomy involved. Check documentation if the organ or structure is not specified.
Do not use for
Do not use this code for routine postoperative pain, uncomplicated healing, or a hematoma/seroma unrelated to a procedure. Do not assign it when the affected site is outside the endocrine system.
Coding tip
Link the complication to the operative site and confirm the endocrine organ or structure in the record before coding.
