Poisoning by methylphenidate, assault, initial encounter

This code signifies an intentional act of harm where methylphenidate, a central nervous system stimulant, was administered or ingested by another person with the intent to poison. The patient is in the active phase of treatment for the acute effects of this poisoning.

Apply this code when documenting a patient presenting with symptoms of methylphenidate toxicity due to an assault. This includes situations where the drug was forcibly given, secretly administered, or otherwise used by another individual to cause harm. It is used for the initial hospitalization or encounter for this specific poisoning event.

• Always sequence this code after the primary diagnosis indicating the specific manifestation of the poisoning.
• Requires an external cause code (X92-Y09) to fully describe the circumstances of the assault.
• Ensure documentation clearly states the intent of assault and the substance involved.
