Burn of other parts of respiratory tract, initial encounter

This code signifies a thermal injury to any part of the respiratory tract other than the larynx or trachea. This includes burns to the bronchi, lungs, or other unspecified respiratory structures. The injury is acute and represents the first time the patient is receiving active treatment for this specific burn.

Apply this code when documentation indicates a burn affecting the lower respiratory tract, such as the bronchial tree or lung parenchyma, resulting from heat, fire, or hot substances. This is appropriate for the initial hospital admission or emergency department visit for the burn.

• Ensure the documentation clearly specifies a burn to a respiratory tract component other than the larynx or trachea.
• Confirm the encounter is for the initial treatment of the burn; subsequent encounters will require a different seventh character.
• Always code the external cause of the burn (e.g., X00-X19) in addition to the burn code.
