About ICD-9-CM 985.1

985.1 is an ICD-9-CM diagnosis code for toxic effect of arsenic 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 T57.0X1A (Toxic effect of arsenic and its compounds, accidental (unintentional), initial encounter), T57.0X2A (Toxic effect of arsenic and its compounds, intentional self-harm, initial encounter) and T57.0X3A (Toxic effect of arsenic and its compounds, assault, initial encounter). All of these are approximate matches, so review the record to pick the right one.
