Contusion of ascending [right] colon, initial encounter

This code signifies a bruise or superficial injury to the ascending colon, which is the initial segment of the large intestine on the right side of the abdomen. It indicates that the injury does not involve a laceration or rupture of the bowel wall, but rather damage to the tissue without a break in continuity. This is the first time this specific injury is being treated.

Use this code for patients presenting with abdominal trauma, such as from a seatbelt injury in a motor vehicle accident or a direct blow to the right abdomen, where diagnostic imaging (e.g., CT scan) confirms a contusion of the ascending colon without perforation. It is appropriate when the patient is initially evaluated and treated for this specific injury.

• Always confirm the specific segment of the colon involved; this code is only for the ascending colon.
• Ensure documentation clearly states "contusion" and rules out more severe injuries like laceration or perforation.
• Verify that this is the initial encounter for treatment of this specific injury; subsequent encounters will require a different seventh character.
