About ICD-9-CM 981
981 is an ICD-9-CM diagnosis code for toxic effect of petroleum products. 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 T52.0X1A (Toxic effect of petroleum products, accidental (unintentional), initial encounter), T52.0X2A (Toxic effect of petroleum products, intentional self-harm, initial encounter) and T52.0X3A (Toxic effect of petroleum products, assault, initial encounter). All of these are approximate matches, so review the record to pick the right one.
