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

This code signifies the long-term or residual health problems resulting from an accidental exposure to fluorine gas or hydrogen fluoride. These sequelae can manifest as chronic respiratory issues, persistent skin damage, or other lasting systemic effects that developed after the initial acute toxic event has resolved.

Use this code when documenting conditions like chronic obstructive pulmonary disease (COPD) or persistent interstitial lung disease that are directly attributed to a past, unintentional inhalation of fluorine gas. It is also appropriate for chronic dermatological conditions, such as scarring or persistent dermatitis, that are a direct consequence of accidental hydrogen fluoride skin contact.

• This "S" seventh character indicates a sequela, meaning the patient is experiencing the residual effects of a past injury or condition.
• Always sequence this code after the codes for the specific sequelae being treated (e.g., chronic bronchitis, skin ulcer).
• Ensure documentation clearly links the current condition to a past accidental exposure to fluorine gas or hydrogen fluoride.
