989.9 — Toxic effect of unspecified substance, chiefly nonmedicinal as to source

989.9 is an ICD-9-CM diagnosis code for toxic effect of unspecified substance, chiefly nonmedicinal as to source. 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 8 ICD-10-CM codes, such as T57.91XA (Toxic effect of unspecified inorganic substance, accidental (unintentional), initial encounter), T57.92XA (Toxic effect of unspecified inorganic substance, intentional self-harm, initial encounter) and T57.93XA (Toxic effect of unspecified inorganic substance, assault, initial encounter). All of these are approximate matches, so review the record to pick the right one.
