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

This code signifies the long-term or residual health problems resulting from a deliberate act of self-harm involving exposure to fluorine gas or hydrogen fluoride. These sequelae can include chronic respiratory issues, persistent skin damage, or other systemic effects that manifest after the initial acute toxic event has resolved.

Apply this code when documenting conditions that are a direct consequence of a past intentional self-poisoning by fluorine gas or hydrogen fluoride. This is appropriate for follow-up encounters where the patient is being treated for the lasting effects, not the acute poisoning itself. It should be used after the acute phase of the toxic effect has passed.

• Always sequence this code after the code(s) for the specific sequela being treated (e.g., chronic bronchitis, skin ulcer).
• Ensure documentation clearly links the current condition to a past intentional self-harm event involving fluorine gas or hydrogen fluoride.
• Do not use for acute poisoning; refer to the appropriate acute toxic effect codes for initial encounters.
