About ICD-9-CM 806.18

806.18 is an ICD-9-CM diagnosis code for open fracture of C5-C7 level with central cord syndrome. 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 9 ICD-10-CM codes, such as S12.400B (Unspecified displaced fracture of fifth cervical vertebra, initial encounter for open fracture), S12.401B (Unspecified nondisplaced fracture of fifth cervical vertebra, initial encounter for open fracture) and S12.500B (Unspecified displaced fracture of sixth cervical vertebra, initial encounter for open fracture). 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.
