ICD-10 Code K91.840 – Postprocedural hemorrhage of a digestive system organ or structure following a digestive system procedure (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code K91.840 – Postprocedural hemorrhage of a digestive system organ or structure following a digestive system procedure
What it is
K91.840 identifies bleeding that occurs after a procedure involving a digestive system organ or structure. Use it when the hemorrhage is documented as a postoperative complication rather than an expected part of recovery.
Clinical signs
Clinical features vary; refer to documentation. Commonly, the chart may note postoperative bleeding, hematemesis, melena, rectal bleeding, or evidence of hemorrhage at the procedure site.
When to use this code
Use this code when the provider documents postprocedural hemorrhage affecting a digestive organ or structure after a GI procedure. It applies when the bleeding is clearly linked to the procedure and is not described as incidental or routine. Check documentation for the exact site and timing.
Do not use for
Do not use this code for bleeding unrelated to a digestive system procedure or for preexisting gastrointestinal hemorrhage. Do not assign it when the record only states postoperative pain, anemia, or unspecified complications without hemorrhage.
Coding tip
Code the complication only when the provider links the bleeding to the procedure and documents the digestive site clearly.
