Poisoning by cocaine, undetermined, subsequent encounter

This code signifies a patient presenting for follow-up care or sequelae related to cocaine poisoning, where the intent of the poisoning (e.g., accidental, intentional self-harm, assault) cannot be determined. The patient is no longer in the acute phase of the poisoning but is receiving ongoing treatment or monitoring for its effects.

Use this code for patients returning for appointments concerning complications, long-term effects, or ongoing management stemming from a cocaine overdose or toxic exposure of unknown intent. This includes scenarios like follow-up for cardiac arrhythmias, neurological deficits, or psychiatric issues attributed to the past cocaine poisoning.

• Ensure documentation clearly states the encounter is for sequelae or follow-up of a past poisoning, not the initial acute event.
• Confirm the intent of the poisoning is explicitly documented as "undetermined" or cannot be ascertained from the medical record.
• Always code any associated manifestations or complications of the poisoning, such as specific organ damage, in addition to this code.
