Tox eff of fluorine gas and hydrogen fluoride, slf-hrm, init

This code signifies a patient presenting with adverse health effects resulting from deliberate exposure to fluorine gas or hydrogen fluoride. These toxic effects are not accidental but are the result of an intentional act of self-harm.

Apply this code when documentation clearly indicates a patient intentionally inhaled or otherwise exposed themselves to fluorine gas or hydrogen fluoride, leading to a toxic reaction. This is appropriate for the initial visit for evaluation and treatment of such an event, such as in an emergency department or initial inpatient admission.

• Always ensure the documentation explicitly states "intentional self-harm" or similar language to support the intent.
• Confirm the substance involved is specifically fluorine gas or hydrogen fluoride, not other toxic gases.
• This "initial encounter" indicator is used as long as the patient is receiving active treatment for the toxic effect.
