ICD-9-CM diagnosis code (retired)
985.8 — Toxic effect of other specified metals
About ICD-9-CM 985.8
985.8 is an ICD-9-CM diagnosis code for toxic effect of other specified metals. 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 16 ICD-10-CM codes, such as T56.4X1A (Toxic effect of copper and its compounds, accidental (unintentional), initial encounter), T56.4X2A (Toxic effect of copper and its compounds, intentional self-harm, initial encounter) and T56.4X3A (Toxic effect of copper and its compounds, assault, initial encounter). All of these are approximate matches, so review the record to pick the right one.
