ICD-10 Code K91.872 – Postprocedural seroma of a digestive system organ or structure following a digestive system procedure (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code K91.872 – Postprocedural seroma of a digestive system organ or structure following a digestive system procedure
What it is
This code identifies a seroma, or localized fluid collection, that develops after a digestive system procedure and involves a digestive organ or structure. It reflects a postoperative complication, not the original disease.
Clinical signs
Findings may include a palpable swelling, fluid collection on imaging, or postoperative discomfort at the surgical site. Clinical features vary; refer to documentation.
When to use this code
Use K91.872 when the record clearly states a postprocedural seroma affecting a digestive organ or structure after a digestive system procedure. You may also use it when imaging or operative notes document a seroma as the complication being treated or monitored. Check documentation if the site or postoperative relationship is unclear.
Do not use for
Do not use this code for abscess, hematoma, infection, or nonspecific postoperative swelling unless the provider documents seroma. Do not assign it when the fluid collection is unrelated to a digestive system procedure.
Coding tip
Link the seroma to the specific digestive procedure in the note, and verify that the complication is documented as postoperative.
