ICD-9-CM diagnosis code (retired)
987.8 — Toxic effect of other specified gases, fumes, or vapors
About ICD-9-CM 987.8
987.8 is an ICD-9-CM diagnosis code for toxic effect of other specified gases, fumes, or vapors. 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 20 ICD-10-CM codes, such as T59.5X1A (Toxic effect of fluorine gas and hydrogen fluoride, accidental (unintentional), initial encounter), T59.5X2A (Toxic effect of fluorine gas and hydrogen fluoride, intentional self-harm, initial encounter) and T59.5X3A (Toxic effect of fluorine gas and hydrogen fluoride, assault, initial encounter). All of these are approximate matches, so review the record to pick the right one.
