About the X13 Code Range
The ICD-10 code X13 covers injuries resulting from contact with steam and other hot vapors. This includes both inhalation injuries and burns caused by direct contact with hot steam or vapor sources.
The code set distinguishes between inhalation of steam and hot vapors (X13.0) and other contact such as skin burns (X13.1). For example, burns caused by steam from a kettle or vehicle radiator fall under X13.1, with synonyms like "steam burn of skin" and "burning due to contact with hot steam." These codes include specific designations for the initial medical encounter (XXA), subsequent visits (XXD), and sequelae or late effects of the injury (XXS), helping to accurately capture the timeline of treatment. Using the correct ICD-10 code for steam inhalation or steam burn injuries ensures precise documentation of external causes related to hot vapor exposure.
