Unspecified injury of unspecified part of colon, sequela

This code indicates a long-term complication or late effect resulting from an unspecified injury to an unspecified part of the colon. It signifies that the initial acute injury has resolved, but its lasting consequences are still present and require ongoing management. The specific nature of the original injury and the exact location within the colon are not documented.

Apply this code when documenting a patient presenting with a current condition directly attributable to a past, unspecified colon injury, and the acute phase of that injury has passed. This is appropriate for follow-up encounters addressing chronic issues like adhesions, strictures, or functional impairments stemming from a prior colon trauma where the initial injury details are no longer available or were never precisely identified.

• Always strive for a more specific code if the type of colon injury (e.g., laceration, contusion) or the specific segment of the colon (e.g., ascending, transverse) is known.
• This code requires a seventh character "S" for sequela, indicating a late effect. Ensure the documentation clearly supports a sequela.
• Avoid using this code for acute injuries; it is strictly for chronic conditions resulting from a past injury.
