Primary blast injury of bronchus, unilateral, sequela

This code signifies a long-term or late-appearing complication resulting from a primary blast injury that specifically affected one of the main airways (bronchus). This type of injury is typically caused by the direct impact of a blast wave, leading to immediate and potentially delayed damage to the respiratory system. The "sequela" aspect indicates that the current condition is a residual effect of that initial blast trauma.

Apply this code when documenting a patient presenting with a chronic or delayed respiratory issue, such as bronchial stenosis, chronic cough, or recurrent infections, that is directly attributed to a primary blast injury sustained in the past. This code is appropriate for follow-up encounters where the long-term consequences of the initial blast trauma to a single bronchus are being managed.

• Ensure documentation clearly links the current bronchial condition to a past primary blast injury.
• Verify laterality (unilateral) is explicitly stated in the medical record.
• This "S" code indicates a sequela; do not use for acute blast injuries.
