Contusion of ascending [right] colon, sequela

This code signifies a long-term complication or late effect resulting from a previous contusion (bruise) to the ascending colon, which is the first part of the large intestine on the right side of the abdomen. It indicates that the initial injury has resolved, but residual issues or conditions directly attributable to that contusion are now being addressed.

Use this code when documenting conditions such as chronic pain, adhesions, strictures, or other functional impairments that are a direct consequence of a contusion to the ascending colon that occurred in the past. This code is appropriate when the patient is presenting for treatment of these lingering effects, not for the initial acute injury.

• Always sequence this code after the code for the specific sequela being treated (e.g., chronic pain, intestinal obstruction).
• Ensure documentation clearly links the current condition to a past ascending colon contusion.
• Do not use this code for the initial or acute treatment of a contusion; use the acute injury code instead.
