ICD-9-CM diagnosis code (retired)
964.6 — Poisoning by gamma globulin
About ICD-9-CM 964.6
964.6 is an ICD-9-CM diagnosis code for poisoning by gamma globulin. 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 5 ICD-10-CM codes, such as T45.8X1A (Poisoning by other primarily systemic and hematological agents, accidental (unintentional), initial encounter), T50.Z11A (Poisoning by immunoglobulin, accidental (unintentional), initial encounter) and T50.Z12A (Poisoning by immunoglobulin, intentional self-harm, initial encounter). All of these are approximate matches, so review the record to pick the right one.
