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

This code signifies the long-term, residual health problems resulting from a toxic exposure to fluorine gas or hydrogen fluoride, specifically when the exposure was due to an assault. These sequelae can manifest as chronic respiratory issues, skin conditions, or other systemic effects that persist after the acute phase of the poisoning has resolved.

Apply this code when documenting a patient presenting with persistent health complications directly attributable to a past assault involving fluorine gas or hydrogen fluoride. This would be used for follow-up visits or evaluations of chronic conditions stemming from such an event. It is appropriate when the acute toxic effects are no longer present, but the lasting damage requires ongoing medical attention.

• Always use this code as a secondary diagnosis, following the code for the specific sequela (e.g., chronic bronchitis, dermatological scar).
• Ensure documentation clearly links the current condition to a past assault involving fluorine gas or hydrogen fluoride.
• Verify the "S" seventh character is appropriate, indicating a sequela, not an initial encounter or subsequent encounter for the acute poisoning.
