Injury of unspecified iliac vein, initial encounter

This code signifies an injury to an iliac vein, but the specific iliac vein (e.g., common, external, internal) is not documented. This type of injury can result in significant hemorrhage and compromise venous return from the lower extremity and pelvis.

This code is appropriate when a patient presents with trauma to the pelvic region, and imaging or surgical exploration confirms an injury to an iliac vein, but the precise anatomical branch is not specified in the medical record. It is used for the initial treatment of such an injury.

• Only use this code when the specific iliac vein injured is truly unknown or unstated in the documentation.
• Always seek clarification from the provider if the specific iliac vein can be identified to allow for more precise coding.
• Remember the "A" suffix indicates an initial encounter for active treatment of the injury.
