Contusion of unspecified part of colon, initial encounter

This code signifies a bruise to an unspecified section of the large intestine, typically resulting from blunt force trauma. It indicates damage to the colon tissue without a full-thickness tear or perforation.

Apply this code when documentation confirms a contusion of the colon, but the specific segment (e.g., ascending, transverse, descending) is not identified. This is often seen in initial evaluations following abdominal trauma where imaging may show bruising but lacks precise anatomical detail.

• Ensure the documentation explicitly states "contusion" and not a laceration or rupture.
• Only use this code when the specific colon segment is truly unspecified; otherwise, code to the highest level of specificity.
• The "A" at the end indicates an initial encounter for this condition.
