Unspecified injury of descending colon, subsequent encounter

This code indicates an unspecified injury to the descending (left) portion of the large intestine, diagnosed during a follow-up visit after initial treatment. The nature of the original injury, such as a contusion, laceration, or perforation, is not specified in the medical record.

Use this code for subsequent encounters when a patient is receiving ongoing care for an injury to the descending colon, and the specific type of injury was not documented or is no longer the primary focus. This applies to situations like wound checks, medication adjustments, or monitoring for complications after initial treatment.

• Requires a seventh character "D" for subsequent encounter, indicating active treatment is ongoing.
• Only use when the specific type of descending colon injury is truly unspecified in the documentation.
• Always seek more specific codes if the type of injury (e.g., laceration, perforation) is known.
