About ICD-9-CM 975.1

975.1 is an ICD-9-CM diagnosis code for poisoning by smooth 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 3 ICD-10-CM codes, such as T48.201A (Poisoning by unspecified drugs acting on muscles, accidental (unintentional), initial encounter), T48.291A (Poisoning by other drugs acting on muscles, accidental (unintentional), initial encounter) and T48.294A (Poisoning by other drugs acting on muscles, undetermined, initial encounter). All of these are approximate matches, so review the record to pick the right one.
