Toxic effect of tin and its compounds, undetermined, init

This code signifies an adverse health effect resulting from exposure to tin or its compounds, where the intent of the exposure (e.g., accidental, intentional self-harm, assault) cannot be determined. It represents the initial phase of treatment for such a toxic reaction.

Use this code when a patient presents with symptoms of tin poisoning, and the medical documentation does not specify whether the exposure was accidental, intentional, or due to assault. This is appropriate for the very first encounter for this specific poisoning event.

• Ensure documentation clearly indicates the toxic agent is tin or a tin compound.
• Confirm that the intent of exposure is explicitly documented as "undetermined."
• Verify this is the patient's first visit for this particular poisoning episode to justify the "A" (initial encounter) seventh character.
