About ICD-9-CM 954.9
954.9 is an ICD-9-CM diagnosis code for injury to unspecified nerve of trunk, excluding shoulder and pelvic girdles. 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 2 ICD-10-CM codes, such as S24.9XXA (Injury of unspecified nerve of thorax, initial encounter) and S34.9XXA (Injury of unspecified nerves at abdomen, lower back and pelvis level, initial encounter). All of these are approximate matches, so review the record to pick the right one.
