T45.4X1Poisoning by iron and its compounds, accidental (unintentional)

T45.4X1 is the ICD-10-CM diagnosis code for poisoning by iron and its compounds, accidental (unintentional). It belongs to category T45 (poisoning by, adverse effect of and underdosing of primarily systemic and hematological agents, not elsewhere classified), block T36-T50 (poisoning by, adverse effects of and underdosing of drugs, medicaments and biological substances) and chapter 19 (injury, poisoning and certain other consequences of external causes). It is a header code, so it can't be reported by itself; one of its 3 subcodes must be used instead.

Within T45.4X (poisoning by, adverse effect of and underdosing of iron and its compounds), T45.4X1 is specifically for poisoning by iron and its compounds, accidental (unintentional). Related codes cover poisoning by iron and its compounds, intentional self-harm (T45.4X2), poisoning by iron and its compounds, assault (T45.4X3), poisoning by iron and its compounds, undetermined (T45.4X4), adverse effect of iron and its compounds (T45.4X5) and underdosing of iron and its compounds (T45.4X6).

Codes in this range require a 7th character: A for initial encounter, D for subsequent encounter and S for sequela. Use placeholder "X" characters to fill any empty positions before the 7th character.

It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
