Poisoning by amphetamines, intentional self-harm, sequela

This code signifies the long-term effects or complications arising from a deliberate overdose or self-poisoning with amphetamines. It indicates that the acute phase of the poisoning has passed, but the patient is still experiencing residual health issues directly attributable to that event. These sequelae can include chronic organ damage, neurological deficits, or persistent psychiatric conditions.

Apply this code when documenting follow-up care for a patient who previously attempted suicide or intentionally harmed themselves by ingesting amphetamines, and they are now presenting with lasting health problems as a direct result. This code is appropriate for conditions such as persistent cardiac arrhythmias, kidney damage, or psychosis that developed after and are linked to the amphetamine poisoning. It should be used after the acute poisoning has been resolved.

• Always sequence this sequela code after the code(s) for the specific residual condition(s) being treated.
• Ensure documentation clearly links the current sequela to the past intentional amphetamine poisoning.
• Do not use this code for acute poisoning events; instead, use the appropriate acute poisoning code with the 7th character "A" for initial encounter.
