Unspecified injury of descending [left] colon, sequela

This code signifies a long-term or late-effect complication resulting from an unspecified injury to the descending (left) colon. It indicates that the initial injury has resolved, but its lasting consequences are now being addressed.

Use this code when documenting a patient presenting with a current condition or symptom that is a direct result of a past, unspecified injury to the descending colon. This applies when the acute phase of the original injury has passed, and the current encounter focuses on managing the residual effects.

• Requires a seventh character "S" to indicate sequela, meaning the residual effect of a past injury.
• Always sequence this code after the code(s) for the specific sequela being treated.
• Ensure documentation clearly links the current condition to a previous descending colon injury.
