ICD-10 Code K91.84 – Postprocedural hemorrhage of a digestive system organ or structure following a procedure (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code K91.84 – Postprocedural hemorrhage of a digestive system organ or structure following a procedure
What it is
K91.84 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, not as the expected surgical blood loss.
Clinical signs
Clinical features vary; refer to documentation. Commonly, the record may describe postoperative bleeding, hematemesis, melena, bloody drain output, or a drop in hemoglobin linked to a recent digestive procedure.
When to use this code
Use K91.84 when the provider states that hemorrhage is due to a prior procedure on the digestive tract or related structure. This includes endoscopic, surgical, or other documented interventions when bleeding is identified as a complication. If the site or causal procedure is unclear, check documentation before coding.
Do not use for
Do not use this code for routine intraoperative blood loss, unrelated gastrointestinal bleeding, or bleeding from a non-digestive site. If the chart does not link the hemorrhage to a procedure, choose a different diagnosis code.
Coding tip
Confirm both the postoperative timing and the documented connection to the digestive procedure before assigning K91.84.
