Primary blast injury of thoracic trachea, subs encntr

This code signifies a primary blast injury affecting the thoracic portion of the trachea, meaning the damage was directly caused by the overpressure wave of an explosion. This type of injury can range from contusions to severe lacerations or ruptures of the tracheal wall.

Apply this code when documenting follow-up care for a patient who previously sustained a primary blast injury to the thoracic trachea. This includes subsequent hospital visits, rehabilitation, or ongoing management of complications arising from the initial blast trauma.

• Ensure documentation clearly specifies "primary blast injury" and the "thoracic" location.
• The "D" seventh character indicates a subsequent encounter, meaning the patient is receiving routine care during the healing or recovery phase.
• Do not use for injuries caused by secondary blast effects (e.g., projectiles) or tertiary blast effects (e.g., patient displacement).
