ICD-10 Code K91.6 – Intraoperative hemorrhage and hematoma of a digestive system organ or structure complicating a procedure (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code K91.6 – Intraoperative hemorrhage and hematoma of a digestive system organ or structure complicating a procedure
What it is
K91.6 identifies bleeding or a hematoma that occurs during a procedure involving a digestive system organ or structure. Use it when the operative complication is documented as intraoperative and related to the digestive tract.
Clinical signs
Clinical features vary; refer to documentation. Typical operative notes may describe unexpected bleeding, hematoma formation, or the need for hemostasis during the procedure.
When to use this code
Use K91.6 when the surgeon documents intraoperative hemorrhage or hematoma as a complication of a digestive system procedure. It applies when the event happens during the operation and involves a digestive organ or related structure.
Code it from the operative report or procedure note, not from routine postoperative bleeding unless the record clearly ties the event to the operation itself. Check documentation for the exact organ and complication wording.
Do not use for
Do not use this code for postoperative hemorrhage, nonspecific GI bleeding, or bleeding unrelated to a procedure. If the chart does not clearly state an intraoperative digestive system complication, check documentation.
Coding tip
Link the complication to the operative procedure and document the specific digestive site whenever the record provides it.
