About ICD-9-CM 966.2
966.2 is an ICD-9-CM diagnosis code for poisoning by succinimides. 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 T42.2X1A (Poisoning by succinimides and oxazolidinediones, accidental (unintentional), initial encounter), T42.2X2A (Poisoning by succinimides and oxazolidinediones, intentional self-harm, initial encounter) and T42.2X3A (Poisoning by succinimides and oxazolidinediones, assault, initial encounter). All of these are approximate matches, so review the record to pick the right one.
