Toxic effect of freon

This code represents the adverse health effects resulting from exposure to freon, a halogenated hydrocarbon often used as a refrigerant or propellant. The toxic effects can range from mild irritation to severe systemic damage, affecting the respiratory, cardiovascular, or central nervous systems.

Use this code when a patient presents with symptoms directly attributable to freon exposure, such as respiratory distress, cardiac arrhythmias, or neurological impairment. Documentation should clearly state the patient's exposure to freon and the resulting toxic manifestations. This code is appropriate for both accidental and intentional exposures.

• Always code the specific manifestation of the toxic effect first, if known (e.g., acute bronchitis due to chemical fumes).
• Distinguish between toxic effects (adverse reactions to a substance) and allergic reactions.
• Consider an E-code to specify the circumstances of the freon exposure (e.g., accidental, intentional self-harm).
