Primary blast injury of bronchus, bilateral, sequela

This code signifies long-term effects or complications arising from a primary blast injury that affected both bronchi. A primary blast injury is caused by the direct impact of a blast wave on the body, and in this case, it specifically damaged the main airways leading to the lungs. "Sequela" indicates that this code is used to report conditions that are residual or chronic after the initial injury has healed.

Use this code when documenting chronic respiratory issues, structural changes, or functional impairments in both bronchi that are directly attributable to a primary blast injury. This would apply to patients presenting with persistent symptoms such as chronic cough, shortness of breath, or recurrent infections, where the etiology is clearly linked to a past blast event. It is appropriate for follow-up encounters addressing these lasting effects.

• Always assign this code as a secondary diagnosis, following the code for the specific sequela being treated (e.g., chronic bronchitis, bronchiectasis).
• Ensure documentation clearly links the current bilateral bronchial condition to a past primary blast injury.
• Do not use for acute blast injuries; this code is exclusively for the long-term consequences.
