Poisoning by 4-Aminophenol derivatives, assault, subs encntr

This code signifies a patient presenting for follow-up care related to an intentional poisoning by 4-aminophenol derivatives, such as acetaminophen, where the poisoning was inflicted by another person. The patient is no longer in the acute phase of treatment but requires ongoing management or monitoring for the effects of the toxic exposure.

Use this code for subsequent encounters when a patient is receiving ongoing care for complications, monitoring for long-term effects, or follow-up after initial treatment for an assault-related poisoning by 4-aminophenol derivatives. This includes visits for liver function tests, medication adjustments, or psychological support stemming from the poisoning event.

• Ensure the documentation clearly specifies the poisoning was an assault and not accidental or self-harm.
• Verify that the encounter is for follow-up care, not the initial treatment of the acute poisoning.
• Always code the specific substance (4-aminophenol derivatives) when documented.
