ICD-10 Code K91.871 – Postprocedural hematoma of a digestive system organ or structure following other procedure (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code K91.871 – Postprocedural hematoma of a digestive system organ or structure following other procedure
What it is
K91.871 identifies a hematoma that develops in a digestive system organ or structure after another procedure. Use it when the record clearly links the bleeding collection to a prior intervention.
Clinical signs
Findings may include localized pain, swelling, tenderness, or evidence of internal bleeding at the procedure site. Clinical features vary; refer to documentation for the affected organ, timing, and confirmed postoperative complication.
When to use this code
Use this code when the provider documents a postprocedural hematoma involving a digestive organ or related structure after a procedure other than the one named in a more specific code. It is appropriate when the complication is clearly postoperative and not a routine expected finding. Check documentation for the exact site and causal procedure.
Do not use for
Do not use it for nonprocedural traumatic hematomas or for postoperative bleeding without a documented hematoma. If the record does not confirm a digestive system organ or structure, check documentation.
Coding tip
Assign the code only when the provider explicitly documents a postprocedural hematoma and identifies the digestive site.
