Primary blast injury of unsp part of colon, init encntr

This diagnosis code signifies damage to the colon resulting directly from the impact of a blast wave, without specifying the exact segment of the colon affected. This type of injury is typically caused by high-energy explosions, leading to barotrauma within the abdominal cavity.

Apply this code for patients presenting with colonic injury confirmed to be a direct consequence of a blast event, such as from an improvised explosive device or other explosive ordnance. This code is appropriate when the specific location of the colonic injury (e.g., ascending, transverse, descending, sigmoid) has not yet been determined or documented.

• Ensure documentation clearly links the colonic injury to a primary blast mechanism.
• Only use this code for the initial encounter for treatment of the injury.
• If a more specific part of the colon is identified, use a more precise code from the S36.51- series.
