Poisoning by amphetamines, intentional self-harm, subs

This code signifies a patient's self-inflicted overdose or toxic reaction to amphetamines, such as dextroamphetamine or methamphetamine, during a follow-up visit. It indicates that the initial treatment for the poisoning has already occurred, and the patient is now receiving ongoing care related to the event.

This code is appropriate for subsequent encounters where a patient is being treated for complications, sequelae, or ongoing management directly resulting from an intentional amphetamine self-poisoning. Examples include follow-up appointments for organ damage, psychiatric evaluation after stabilization, or monitoring for long-term effects.

• Always assign an additional code for the specific amphetamine involved, if known.
• Do not use this code for initial treatment of the poisoning; use the "A" (initial encounter) seventh character instead.
• Consider additional codes for any co-occurring mental health conditions or physical injuries sustained during the self-harm event.
