About ICD-9-CM 805.11

805.11 is an ICD-9-CM diagnosis code for open fracture of first 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 S12.000B (Unspecified displaced fracture of first cervical vertebra, initial encounter for open fracture) and S12.001B (Unspecified nondisplaced fracture of first cervical vertebra, initial encounter for open fracture). All of these are approximate matches, so review the record to pick the right one.
