ICD-9-CM diagnosis code (retired)
972.6 — Poisoning by other antihypertensive agents
About ICD-9-CM 972.6
972.6 is an ICD-9-CM diagnosis code for poisoning by other antihypertensive agents. 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 T46.4X1A (Poisoning by angiotensin-converting-enzyme inhibitors, accidental (unintentional), initial encounter), T46.4X2A (Poisoning by angiotensin-converting-enzyme inhibitors, intentional self-harm, initial encounter) and T46.4X3A (Poisoning by angiotensin-converting-enzyme inhibitors, assault, initial encounter). All of these are approximate matches, so review the record to pick the right one.
