Contusion of sigmoid colon, initial encounter

This code signifies a bruise or superficial injury to the sigmoid colon, a part of the large intestine, without a full-thickness tear or perforation. It indicates damage to the colon tissue, typically resulting from blunt force trauma, but the integrity of the bowel wall remains intact.

This code is appropriate for documenting an initial presentation of a patient who has sustained a contusion to the sigmoid colon, often following abdominal trauma such as a motor vehicle accident, fall, or direct impact. It should be used when diagnostic imaging (e.g., CT scan) confirms a localized injury to the sigmoid colon without evidence of more severe damage like laceration or rupture.

• Ensure documentation clearly specifies "contusion" and the "sigmoid colon" as the injured site.
• Verify that the encounter is the "initial encounter" for this specific injury. Subsequent care would require a different seventh character.
• Distinguish from more severe injuries like lacerations or perforations, which have distinct codes.
