Unsp injury of intercostal blood vessels, left side, init

This diagnosis code indicates an injury to any blood vessel located between the ribs on the left side of the chest, where the specific type of vessel (artery or vein) is not documented. This injury could involve a contusion, laceration, or other damage to these vessels.

This code is appropriate for initial encounters when a patient presents with evidence of trauma to the left intercostal region, and imaging or surgical findings confirm an intercostal blood vessel injury, but the documentation does not specify whether it's an artery or vein. It is commonly seen in cases of blunt or penetrating chest trauma.

• Ensure documentation clearly specifies the left side; otherwise, an unspecified side code should be used.
• Only use this code for the initial encounter for the injury. Subsequent care would require a different encounter character.
• If the documentation specifies an intercostal artery or vein injury, a more specific code should be selected.
