Intraop hemor/hemtom of a circ sys org comp oth procedure

This code signifies an acute bleeding event or blood collection within a circulatory system organ or structure that occurs during a surgical or other invasive procedure. It represents an unexpected and undesirable complication directly related to the intervention on a blood vessel, heart, or other component of the circulatory system. This complication can range from minor oozing requiring additional hemostasis to significant hemorrhage necessitating transfusion or further surgical intervention.

This code is appropriate when documentation clearly indicates intraoperative bleeding or hematoma formation within a circulatory system organ or structure during a procedure not primarily intended to address hemorrhage. Examples include bleeding from a coronary artery during bypass grafting, or a hematoma forming within an artery during angioplasty. Documentation should specify the circulatory system organ/structure involved and confirm the intraoperative timing of the complication.

• Always sequence this code after the code for the specific procedure performed.
• Ensure documentation differentiates intraoperative hemorrhage from postoperative hemorrhage; different codes apply.
• Do not use this code for expected or controlled bleeding inherent to the surgical approach (e.g., incision bleeding controlled by routine hemostasis).
