Primary blast injury of other part of colon, sequela

This code signifies a long-term or residual effect stemming from a primary blast injury affecting an unspecified or other part of the colon. It indicates that the initial blast trauma has led to ongoing issues or complications within the colonic tissue, rather than an acute injury. The "sequela" designation points to a chronic condition resulting from the original insult.

Apply this code when documenting a patient's current condition that is a direct, lasting consequence of a primary blast injury to the colon. This is appropriate for follow-up encounters where the patient is being treated for chronic pain, altered bowel function, strictures, or other persistent issues directly attributable to the past blast trauma. Do not use for acute blast injuries.

• Ensure documentation clearly links the current colonic condition as a sequela of a primary blast injury.
• This code requires a seventh character of "S" for sequela, indicating the long-term nature of the condition.
• Code any specific manifestations of the sequela (e.g., stricture, fistula) in addition to this code, if applicable.
