ICD-9-CM diagnosis code (retired)
971.3 — Poisoning by sympatholytics [antiadrenergics]
About ICD-9-CM 971.3
971.3 is an ICD-9-CM diagnosis code for poisoning by sympatholytics [antiadrenergics]. 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 T44.6X1A (Poisoning by alpha-adrenoreceptor antagonists, accidental (unintentional), initial encounter), T44.6X2A (Poisoning by alpha-adrenoreceptor antagonists, intentional self-harm, initial encounter) and T44.6X3A (Poisoning by alpha-adrenoreceptor antagonists, assault, initial encounter). All of these are approximate matches, so review the record to pick the right one.
