Unspecified injury of ascending [right] colon, sequela

This code signifies a long-term complication or late effect stemming from an injury to the ascending (right) colon, where the specific nature of the original injury was not documented. It indicates that the patient is presenting for care related to a residual condition or problem that arose as a direct consequence of a past, unspecified trauma to this part of the large intestine.

Apply this code when a patient is being treated for a sequela (e.g., adhesions, stricture, chronic pain, fistula) resulting from a previous, uncharacterized injury to the ascending colon. This is appropriate when the acute phase of the original injury has passed, and the current encounter addresses a persistent or delayed complication.

• Always sequence this code after the code for the specific sequela being treated.
• Ensure documentation clearly links the current condition to a past, unspecified injury of the ascending colon.
• Avoid using this code for acute injuries; it is exclusively for late effects.
