About ICD-9-CM 964.2
964.2 is an ICD-9-CM diagnosis code for poisoning by anticoagulants. 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 T45.511A (Poisoning by anticoagulants, accidental (unintentional), initial encounter), T45.512A (Poisoning by anticoagulants, intentional self-harm, initial encounter) and T45.513A (Poisoning by anticoagulants, assault, initial encounter). All of these are approximate matches, so review the record to pick the right one.
