About the X10–X19 Code Range
This ICD-10 code range X10-X19 covers injuries resulting from contact with various heat sources and hot substances. These codes specifically track burns and scalds caused by hot drinks, foods, liquids, vapors, household appliances, engines, metals, and other heat sources.
The codes in this group detail the type of hot substance involved, such as X10 for hot drinks (including coffee or tea burns), X15 for hot household appliances like stoves and toasters, and X13 for inhalation of steam and hot vapors. Each code includes subcategories for the stage of treatment: initial encounter (e.g., X10.0XXA for first treatment of a hot drink burn), subsequent encounters (X10.0XXD), and sequela or long-term effects (X10.0XXS). Synonyms like "scald of skin," "burn by hot liquid," or "steam burn of skin" help clarify the appropriate use of codes when coding burns from hot liquids, steam, cooking oils, or appliances. This detailed coding supports accurate recording of accidental thermal injuries and their progression or complications over time.
