About ICD-9-CM 839.16

839.16 is an ICD-9-CM diagnosis code for open dislocation, sixth cervical vertebra. 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 S11.90XA (Unspecified open wound of unspecified part of neck, initial encounter) and S13.161A (Dislocation of C5/C6 cervical vertebrae, 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.
