Poisoning by 4-Aminophenol derivatives, self-harm, subs

This code signifies a deliberate act of self-poisoning using 4-Aminophenol derivatives, such as acetaminophen, where the patient is receiving follow-up care for the initial injury. It indicates that the patient intentionally ingested or was exposed to these substances with the intent to harm themselves, and the current encounter is for ongoing management or complications.

Apply this code when documenting subsequent encounters for a patient who previously presented with an intentional overdose of 4-Aminophenol derivatives. This includes visits for monitoring liver function, managing renal complications, addressing psychiatric sequelae related to the self-harm attempt, or follow-up after initial stabilization.

• Ensure documentation clearly states "intentional self-harm" and that the encounter is not the initial presentation.
• Always sequence this code after any codes for the specific manifestations or complications of the poisoning (e.g., acute liver failure).
• Verify the substance involved is a 4-Aminophenol derivative to ensure accurate code selection.
