About ICD-9-CM 839.18

839.18 is an ICD-9-CM diagnosis code for open dislocation, multiple cervical vertebrae. 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 S13.101A (Dislocation of unspecified 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.
