About ICD-9-CM 843.9
843.9 is an ICD-9-CM diagnosis code for sprains and strains of unspecified site of hip and thigh. 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 S73.109A (Unspecified sprain of unspecified hip, initial encounter) and S76.919A (Strain of unspecified muscles, fascia and tendons at thigh level, unspecified thigh, initial encounter). All of these are approximate matches, so review the record to pick the right one.
