Toxic effect of unsp metal, intentional self-harm, subs

This code signifies a patient presenting for follow-up care related to a toxic exposure to an unspecified metal, where the original exposure was an intentional act of self-harm. The patient is no longer in the acute phase of treatment but is receiving ongoing management for the effects of the poisoning.

Use this code for subsequent encounters when a patient is being treated for complications or ongoing effects from a prior intentional self-poisoning with an unspecified metal. This includes follow-up visits for organ damage, neurological sequelae, or psychological support related to the initial event. It is appropriate once the acute phase of the poisoning has passed and the patient is no longer receiving initial active treatment.

• Ensure the encounter is for follow-up care, not the initial acute treatment.
• Confirm the intent was self-harm, not accidental or assault.
• Verify the specific metal involved is not documented, necessitating the "unspecified metal" category.
