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

This code signifies a long-term or residual health problem resulting from exposure to fluorine gas or hydrogen fluoride, where the intent of the exposure (accidental, intentional self-harm, assault) is not documented. It indicates that the acute phase of the poisoning has passed, but the patient continues to experience related symptoms or conditions.

Apply this code for patients presenting with chronic respiratory issues, skin conditions, bone abnormalities, or other persistent health effects directly attributed to past fluorine gas or hydrogen fluoride exposure. This is appropriate when the initial poisoning event is no longer active, but its lasting impact is being treated or monitored.

• Ensure documentation clearly links the current condition to a past fluorine or hydrogen fluoride exposure.
• Only use this code when the intent of the exposure is explicitly unknown or not specified in the medical record.
• Code any specific manifestations of the sequela (e.g., chronic bronchitis, osteofluorosis) in addition to this code.
