Poisoning by penicillins, intentional self-harm, sequela

This code signifies the long-term effects or complications arising from a patient's deliberate overdose of penicillin. It indicates that the initial act of intentional self-poisoning with penicillin has resolved, but the patient is now presenting with residual health issues directly attributable to that event.

Apply this code when documenting conditions like chronic organ damage (e.g., kidney failure, liver damage), neurological deficits, or persistent allergic reactions that are a direct consequence of a past intentional penicillin poisoning. This code is used after the acute phase of the poisoning has passed and the patient is being treated for the lasting sequelae.

• Always sequence this code after the code(s) identifying the specific sequela (e.g., chronic kidney disease).
• Ensure documentation clearly links the current condition to a past intentional penicillin overdose.
• Do not use for acute poisoning; this code is exclusively for residual effects.
