About ICD-9-CM 964.0
964.0 is an ICD-9-CM diagnosis code for poisoning by iron and its compounds. ICD-9-CM was retired for U.S. claims on October 1, 2015, when ICD-10-CM took over.
The CMS General Equivalence Mappings translate it to 4 ICD-10-CM codes, such as T45.4X1A (Poisoning by iron and its compounds, accidental (unintentional), initial encounter), T45.4X2A (Poisoning by iron and its compounds, intentional self-harm, initial encounter) and T45.4X3A (Poisoning by iron and its compounds, assault, initial encounter). All of these are approximate matches, so review the record to pick the right one.
