ICD-9-CM diagnosis code (retired)
975.2 — Poisoning by skeletal muscle relaxants
About ICD-9-CM 975.2
975.2 is an ICD-9-CM diagnosis code for poisoning by skeletal muscle relaxants. 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 T48.1X1A (Poisoning by skeletal muscle relaxants [neuromuscular blocking agents], accidental (unintentional), initial encounter), T48.1X2A (Poisoning by skeletal muscle relaxants [neuromuscular blocking agents], intentional self-harm, initial encounter) and T48.1X3A (Poisoning by skeletal muscle relaxants [neuromuscular blocking agents], assault, initial encounter). All of these are approximate matches, so review the record to pick the right one.
