2025 ICD-10-CM code T27.0

Burn of larynx and trachea.

Use secondary code(s) from Chapter 20, External causes of morbidity, to indicate cause of injury. Codes within the T section that include the external cause do not require an additional external cause code.

Medical necessity for the use of T27.0 is established by the presence of a burn injury to the larynx and trachea. This diagnosis impacts respiratory function and requires specialized medical intervention to ensure airway patency and manage potential complications.

IMPORTANT Use additional code from Chapter 20 (External causes of morbidity) to indicate the cause of the injury. Use additional code to identify any retained foreign body, if applicable (Z18.-).

In simple words: This code describes a burn injury to the voice box (larynx) and windpipe (trachea).

Burn of larynx and trachea. The larynx (voice box) is located in the front of the neck. It plays a crucial role in breathing, speaking, and protecting the trachea from food aspiration. The trachea (windpipe) is a cartilaginous tube that connects the larynx to the bronchi of the lungs, allowing the passage of air.

Example 1: A patient sustains burns to their larynx and trachea due to inhalation of superheated steam during a factory accident., A child accidentally swallows a caustic cleaning agent, resulting in chemical burns to their larynx and trachea., A firefighter suffers burns to their larynx and trachea while rescuing individuals from a burning building.

Documentation should include details of the burn incident, the extent and depth of the burns, the cause of the burn (e.g., thermal, chemical), and any associated injuries. Imaging studies, such as bronchoscopy or CT scan, may be necessary to assess the damage.
