ICD-10 Code K91.870 – Postprocedural hematoma of a digestive system organ or structure following a digestive system procedure (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code K91.870 – Postprocedural hematoma of a digestive system organ or structure following a digestive system procedure
What it is
K91.870 identifies a hematoma that develops in a digestive system organ or structure after a digestive system procedure. It reflects a postoperative bleeding complication, not the original disease that led to surgery.
Clinical signs
Clinical features vary; refer to documentation. Common findings may include localized pain, swelling, tenderness, or evidence of postoperative bleeding at the operative site.
When to use this code
Use this code when the provider documents a hematoma as a complication of a digestive system procedure, such as after surgery, endoscopy, or another intervention involving the GI tract. Code only when the hematoma is clearly linked to the procedure. Check documentation if the record does not specify the site or relationship.
Do not use for
Do not use it for a preexisting hematoma, a hematoma unrelated to a procedure, or nonspecific postoperative pain or bruising without documented hematoma. Check documentation if the complication type is unclear.
Coding tip
Link the hematoma to the specific digestive procedure in the note before assigning K91.870.
