Toxic effect of other metals, intentional self-harm, sequela

This code signifies a long-term health consequence resulting from a prior intentional self-poisoning event involving a metal other than mercury, arsenic, manganese, thallium, or other specified metals. These sequelae can manifest as chronic organ damage, neurological deficits, or other persistent health issues directly attributable to the past toxic exposure. The original intent of self-harm is a crucial component of this diagnosis.

Apply this code when documenting a patient presenting with a current, persistent health condition that is a direct and lasting result of a previous self-inflicted poisoning by an unspecified metal. This code is appropriate for follow-up encounters where the acute phase of the poisoning has resolved, but the patient continues to experience related medical problems. It should be used when the original poisoning was clearly documented as an intentional act of self-harm.

• Always ensure documentation clearly links the current condition to a past intentional self-harm event involving a metal.
• Do not use for acute poisoning or when the intent was accidental or undetermined; specific acute poisoning codes or codes for accidental/undetermined intent should be utilized in those scenarios.
• Code any specific manifestations of the sequela (e.g., chronic kidney disease, neuropathy) in addition to this sequela code.
