Toxic effect of tin and its compounds, undetermined, sequela

This code signifies the long-term or late effects resulting from an exposure to tin or its compounds, where the intent of the exposure (accidental, intentional self-harm, assault) cannot be determined. It indicates that the acute phase of the poisoning has passed, and the patient is now experiencing residual health problems directly attributable to the past toxic event.

Apply this code when documenting chronic neurological, dermatological, or systemic issues that are definitively linked to a prior, unspecified tin exposure. This is appropriate for patients presenting with sequelae such as persistent tremors, skin lesions, or organ damage, where the original poisoning event's circumstances remain unknown.

• Always sequence this code after the code(s) for the specific sequela being treated.
• Ensure documentation clearly links the current condition to a past tin exposure of undetermined intent.
• Avoid using this code for acute poisoning; it is exclusively for residual effects.
