Poisoning by iron and its compounds, undetermined, sequela

This code indicates a long-term health problem or complication resulting from an iron poisoning event where the intent (accidental, intentional self-harm, assault) cannot be determined. The patient is no longer in the acute phase of poisoning but is experiencing residual effects.

Use this code when documenting a chronic condition or permanent damage directly attributable to a past iron poisoning, and the medical record does not specify whether the poisoning was accidental, intentional, or due to assault. This applies to follow-up visits for ongoing management of sequelae.

• Always assign an additional code(s) to specify the nature of the sequela (e.g., liver damage, neurological deficits).
• Do not use this code for acute iron poisoning; refer to the appropriate acute poisoning codes (T45.4X1-T45.4X3).
• Ensure documentation clearly links the current condition to a past, undetermined iron poisoning event.
