Burn of larynx and trachea, sequela

This code signifies the long-term or late effects resulting from a burn injury to the larynx and trachea. These sequelae can include chronic airway obstruction, vocal cord dysfunction, scarring, or other persistent respiratory issues that manifest after the acute burn has healed.

Apply this code when documenting conditions that are a direct consequence of a past burn to the larynx and trachea, and the acute phase of the burn is no longer being treated. This is appropriate for follow-up visits or when managing chronic complications stemming from such an injury.

• Always use this code as a secondary diagnosis, following the code for the specific sequela being treated.
• Ensure documentation clearly links the current condition to a previous burn of the larynx and trachea.
• Do not use this code for acute burn treatment; it is exclusively for residual effects.
