Contusion of descending [left] colon, subsequent encounter

This code signifies a bruise or bleeding within the wall of the descending portion of the left colon. It indicates that the injury is not new but is being treated or evaluated during a follow-up visit after the initial trauma. The contusion typically results from blunt abdominal trauma.

Use this code for follow-up encounters where a patient is being monitored or receiving ongoing treatment for a previously diagnosed contusion of the descending colon. This includes visits for symptom re-evaluation, imaging to assess healing, or management of complications arising from the initial injury. It is appropriate when the patient is no longer in the initial acute phase of treatment.

• Ensure documentation clearly states the encounter is subsequent to the initial injury.
• Verify the specific colon segment (descending colon) and laterality (left) are documented.
• Do not use for the initial encounter; a code without the "D" seventh character would be appropriate for the first visit.
