839.71 — Open dislocation, sternum

839.71 is an ICD-9-CM diagnosis code for open dislocation, sternum. 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 S21.109A (Unspecified open wound of unspecified front wall of thorax without penetration into thoracic cavity, initial encounter) and S43.206A (Unspecified dislocation of unspecified sternoclavicular joint, initial encounter). All of these are approximate matches, so review the record to pick the right one. Some mappings are combinations: more than one ICD-10 code is needed to fully express the ICD-9 code.
