About coding respiratory tract burn
The ICD-10-CM code for respiratory tract burn is T27.3 (Burn of respiratory tract, part unspecified). The official index lists 1 more specific code, so check the documentation for details such as type, cause, site or severity before settling on T27.3.
Within T27, choose T27.3 (Burn of respiratory tract, part unspecified) only when documentation doesn't support a more specific option: burn of larynx and trachea (T27.0), burn involving larynx and trachea with lung (T27.1), burn of other parts of respiratory tract (T27.2), corrosion of larynx and trachea (T27.4), corrosion involving larynx and trachea with lung (T27.5), corrosion of other parts of respiratory tract (T27.6) and corrosion of respiratory tract, part unspecified (T27.7).
Codes in this range require a 7th character: A for initial encounter, D for subsequent encounter and S for sequela. Use placeholder "X" characters to fill any empty positions before the 7th character.
Use an additional code for: external cause code to identify the source and intent of the burn (X00-X19, X75-X77, X96-X98) and external cause code to identify place (Y92).
