Toxic effect of fiberglass, undetermined, sequela

This code signifies the long-term or residual effects resulting from a past exposure to fiberglass, where the intent of the exposure (e.g., accidental, intentional self-harm, assault) cannot be determined. These sequelae might include chronic skin irritation, respiratory issues, or other persistent symptoms that developed after the initial toxic event.

Apply this code when documenting a patient presenting with ongoing health problems directly attributable to a previous fiberglass exposure, and the medical record does not specify the circumstances of that exposure. This is appropriate for follow-up visits where the acute phase of the toxic effect has resolved, but lasting consequences remain.

• Always sequence this code after the code(s) for the specific sequela(e) being treated.
• Ensure documentation clearly links the current condition to a past fiberglass exposure.
• Only use this code when the intent of the original exposure is explicitly documented as "undetermined."
