Toxic eff of fluorine gas and hydrogen fluoride, asslt, init

This code signifies the adverse health effects resulting from exposure to fluorine gas or hydrogen fluoride, specifically when the exposure is due to an intentional act of harm against the patient. The "initial encounter" indicates that this code is used for the period when the patient is receiving active treatment for the acute effects of the poisoning.

Apply this code when documenting a patient presenting with symptoms of fluorine gas or hydrogen fluoride toxicity, and the medical record clearly states that the exposure was a deliberate assault. This would include cases such as chemical attacks or intentional poisoning attempts using these substances. It is appropriate for the initial hospitalization or outpatient visit for the acute management of the toxic effects.

• Always ensure the medical record explicitly documents the "assault" nature of the exposure.
• Pair this code with additional codes for specific manifestations of the toxicity (e.g., respiratory failure, chemical burns).
• Do not use this code for accidental or unintentional exposures; refer to other external cause codes for those scenarios.
