ICD-9-CM diagnosis code (retired)
964.4 — Poisoning by fibrinolysis-affecting drugs
About ICD-9-CM 964.4
964.4 is an ICD-9-CM diagnosis code for poisoning by fibrinolysis-affecting drugs. 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 12 ICD-10-CM codes, such as T45.601A (Poisoning by unspecified fibrinolysis-affecting drugs, accidental (unintentional), initial encounter), T45.602A (Poisoning by unspecified fibrinolysis-affecting drugs, intentional self-harm, initial encounter) and T45.603A (Poisoning by unspecified fibrinolysis-affecting drugs, assault, initial encounter). All of these are approximate matches, so review the record to pick the right one.
