969.1 — Poisoning by phenothiazine-based tranquilizers
About ICD-9-CM 969.1
969.1 is an ICD-9-CM diagnosis code for poisoning by phenothiazine-based tranquilizers. 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 T43.3X1A (Poisoning by phenothiazine antipsychotics and neuroleptics, accidental (unintentional), initial encounter), T43.3X2A (Poisoning by phenothiazine antipsychotics and neuroleptics, intentional self-harm, initial encounter) and T43.3X3A (Poisoning by phenothiazine antipsychotics and neuroleptics, assault, initial encounter). All of these are approximate matches, so review the record to pick the right one.
