Poisoning by methamphetamines self-harm, subs

This code signifies a patient presenting for follow-up care or complications arising from a deliberate overdose or self-poisoning with methamphetamines. It indicates that the initial event of intentional self-harm has already occurred and the patient is now in a subsequent phase of treatment.

Apply this code when documenting ongoing management, monitoring for long-term effects, or treating sequelae of a prior intentional methamphetamine overdose. This includes situations like follow-up appointments after discharge from an acute care setting, or during rehabilitation for substance use disorder directly stemming from the self-harm attempt.

• Requires an external cause code (X62.-) to fully describe the intent and circumstances of the poisoning.
• Do not use for initial encounters or acute poisoning treatment; reserve for subsequent care.
• Always sequence as a primary diagnosis when it is the reason for the encounter, or as a secondary diagnosis when addressing complications.
