ICD-10 Code K91.61 – Intraoperative hemorrhage and hematoma of a digestive system organ or structure complicating a digestive system procedure (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code K91.61 – Intraoperative hemorrhage and hematoma of a digestive system organ or structure complicating a digestive system procedure
What it is
K91.61 identifies bleeding or a hematoma that occurs during a digestive system procedure and involves a digestive organ or structure. Use it when the operative note documents an intraoperative complication, not a routine expected finding.
Clinical signs
Typical documentation may describe active surgical bleeding, a blood collection, or the need for additional hemostasis during the procedure. Clinical features vary; refer to documentation.
When to use this code
Use K91.61 when the surgeon documents intraoperative hemorrhage or hematoma as a complication of a digestive system procedure, such as during an endoscopic or open operation. You should code it from the operative record when the complication is clearly tied to the procedure. Check documentation if the note only mentions postoperative bleeding or an unrelated injury.
Do not use for
Do not use this code for postoperative hemorrhage, delayed bleeding, or bleeding unrelated to a digestive system procedure. If the record does not clearly identify an intraoperative complication, check documentation.
Coding tip
Link the code to the procedure note and the site involved; if the timing or cause is unclear, verify with the surgeon.
