Assault by smoke, fire and flames (X97)

The ICD-10 code X97 covers injuries resulting from assault by smoke, fire, and flames. This includes cases where individuals are harmed deliberately through exposure to fire, burning, or related incendiary acts.

This section is used specifically to classify assaults involving smoke or flames, such as assault by arson, assault by cigarette burn, or any form of intentional fire-related injury. The codes differentiate the stage of care: X97.XXXA for the initial encounter when treatment begins; X97.XXXD for subsequent encounters involving follow-up care; and X97.XXXS for sequela, meaning complications or conditions that develop as a result of the original assault. Using these terms helps healthcare providers and coders accurately document the nature and timing of injuries caused by assaults involving fire and smoke, ensuring precise coding for legal and clinical use. This ICD-10 code is essential for identifying the cause of injury in cases linked to intentional fire violence or smoke exposure.

7th Character Note

Certain ICD-10-CM categories have applicable 7th characters. The applicable 7th character is required for all codes within the category, or as the notes in the Tabular List instruct. The 7th character must always be the 7th character in the data field. If a code that requires a 7th character is not 6 characters, a placeholder X must be used to fill in the empty characters.
