Primary blast injury of transverse colon, sequela

This code signifies a long-term complication or late effect resulting from a primary blast injury that specifically affected the transverse colon. This type of injury occurs directly from the overpressure wave of an explosion, causing damage to hollow organs like the colon. The "sequela" indicates that the initial acute injury has resolved, but the patient is now experiencing a residual condition or consequence directly attributable to that past blast trauma.

Apply this code when documenting a current condition or symptom that is a direct result of a previously sustained primary blast injury to the transverse colon. This would include chronic pain, strictures, fistulas, or other long-term functional impairments of the transverse colon that developed after the initial acute phase of the blast injury. It is used when the patient is no longer in the acute phase of the injury but is being treated for its lasting effects.

• Always sequence this sequela code after the code for the specific manifestation or current condition being treated.
• Ensure documentation clearly links the current transverse colon issue to a past primary blast injury.
• Do not use for acute blast injuries; those require codes from the initial encounter or subsequent encounter categories.
