Primary blast injury of thoracic trachea, sequela

This code signifies a long-term or residual effect from a primary blast injury that specifically affected the thoracic trachea. It indicates that the initial traumatic event has passed, but the patient continues to experience health issues directly attributable to the blast's impact on this part of the airway.

Use this code when documenting ongoing complications, chronic conditions, or permanent damage to the thoracic trachea resulting from a primary blast injury. This would apply to follow-up encounters for patients with persistent tracheal stenosis, tracheomalacia, or other structural or functional impairments directly linked to the original blast trauma.

• Ensure the medical record clearly documents the primary blast as the etiology of the tracheal sequela.
• Do not use for acute blast injuries; this code is specifically for the long-term effects.
• Code any associated current symptoms or conditions separately, if applicable.
