About ICD-9-CM 955.3

955.3 is an ICD-9-CM diagnosis code for injury to radial nerve. 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 S44.20XA (Injury of radial nerve at upper arm level, unspecified arm, initial encounter), S54.20XA (Injury of radial nerve at forearm level, unspecified arm, initial encounter) and S64.20XA (Injury of radial nerve at wrist and hand level of unspecified arm, initial encounter). All of these are approximate matches, so review the record to pick the right one.
