Poisoning by methamphetamines self-harm, initial encounter

This code signifies a patient presenting with adverse effects resulting from the deliberate self-administration of methamphetamines with the intent to cause harm. This includes overdose or other toxic reactions where the patient intentionally ingested, injected, or otherwise exposed themselves to the substance.

Apply this code when documentation clearly indicates a methamphetamine poisoning due to a suicide attempt or other self-destructive act. This is appropriate for the initial visit where the poisoning is being treated.

• Ensure documentation explicitly states "intentional self-harm" or "suicide attempt" in relation to methamphetamine use.
• Always assign an additional code for the specific manifestation of the poisoning (e.g., altered mental status, cardiac arrhythmia).
• This "A" initial encounter seventh character is used for the period when the patient is receiving active treatment for the poisoning.
