About ICD-9-CM 964.8
964.8 is an ICD-9-CM diagnosis code for poisoning by other specified agents affecting blood constituents. 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 T45.621A (Poisoning by hemostatic drug, accidental (unintentional), initial encounter), T45.622A (Poisoning by hemostatic drug, intentional self-harm, initial encounter) and T45.623A (Poisoning by hemostatic drug, assault, initial encounter). All of these are approximate matches, so review the record to pick the right one.
