Poisoning by antifungal antibiot, sys used, undet, sequela

This code signifies a long-term or residual effect resulting from a poisoning event involving antifungal medications taken systemically, where the intent of the poisoning (accidental, intentional self-harm, assault) cannot be determined. It indicates that the acute phase of the poisoning has passed, but the patient continues to experience health problems directly attributable to the past exposure.

Apply this code when documenting a patient presenting with chronic or persistent health issues (e.g., liver damage, kidney dysfunction, neurological deficits) that are definitively linked to a prior systemic antifungal poisoning. This is appropriate when the original poisoning event's circumstances regarding intent remain unknown or unclarified.

• Always use this code as a secondary diagnosis, following the code for the specific sequela (e.g., chronic kidney disease).
• Ensure documentation clearly links the current condition to a past systemic antifungal poisoning of undetermined intent.
• Do not use for acute poisoning events; this "S" seventh character is exclusively for sequelae.
