Contact with other heat and hot substances (X19)

The ICD-10 code X19 refers to injuries caused by contact with other heat and hot substances. This code and its extensions are used to classify burns and injuries from a variety of hot materials and objects during medical diagnosis and billing.

The codes under X19 cover incidents involving exposure to hot substances such as hot plastics, masonry, bricks, concrete, stones, tar, and corrosive materials. Common terms like "accidents due to excessive heat," "burning due to contact with hot solid objects," and "hot tar burn of skin" align with this code, helping medical coders identify the correct classification for burns caused by heat or hot substances. The detailed subcodes specify the stage of treatment: X19.XXXA for initial encounters, X19.XXXD for subsequent encounters, and X19.XXXS for sequela or late effects. These distinctions assist healthcare professionals in accurately documenting the cause and timing of burn injuries related to hot substances.
