ICD-10 Code E89.822 – Postprocedural seroma of an endocrine system organ or structure following an endocrine system procedure (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code E89.822 – Postprocedural seroma of an endocrine system organ or structure following an endocrine system procedure
What it is
This code identifies a seroma, or localized fluid collection, that develops after an endocrine system procedure involving an endocrine organ or structure. It reflects a postoperative complication, not the original disease.
Clinical signs
Typical findings include swelling, a soft or fluctuant mass, and possible discomfort at the surgical site. Clinical features vary; refer to documentation for confirmation that the fluid collection is a seroma.
When to use this code
Use this code when the record clearly states a postprocedural seroma involving an endocrine organ or structure after an endocrine procedure. You may also use it when imaging or operative notes document a postoperative seroma and the provider links it to the endocrine surgery.
Do not assume the complication from routine postoperative swelling alone. Check documentation for the specific endocrine site and whether the seroma is being managed or followed as a postoperative complication.
Do not use for
Do not use it for abscess, hematoma, infection, or nonspecific postoperative pain. Also avoid it when the fluid collection is unrelated to an endocrine procedure or the site is not documented.
Coding tip
Verify both the postoperative nature and the endocrine system site before assigning E89.822.
