Toxic effect of tin and its compounds, self-harm, subs

This code signifies a patient presenting for follow-up care related to a previous poisoning by tin or its compounds, where the exposure was intentionally self-inflicted. The patient is no longer in the acute phase of treatment but requires ongoing management or monitoring for the toxic effects.

Use this code for subsequent visits when a patient is being managed for complications or residual effects of a prior intentional tin poisoning. This includes appointments for monitoring organ function, addressing chronic neurological symptoms, or managing psychological sequelae related to the self-harm attempt.

• Ensure documentation clearly indicates the intentional nature of the poisoning and that the encounter is for follow-up care.
• Always code with an additional diagnosis code for the specific manifestation of the tin toxicity (e.g., neurological, gastrointestinal).
• Consider adding a Z code for self-harm if appropriate and not already documented.
