ICD-9-CM diagnosis code (retired)
806.00 — Closed fracture of C1-C4 level with unspecified spinal cord injury
About ICD-9-CM 806.00
806.00 is an ICD-9-CM diagnosis code for closed fracture of C1-C4 level with unspecified spinal cord injury. 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 12 ICD-10-CM codes, such as S12.000A (Unspecified displaced fracture of first cervical vertebra, initial encounter for closed fracture), S12.001A (Unspecified nondisplaced fracture of first cervical vertebra, initial encounter for closed fracture) and S12.100A (Unspecified displaced fracture of second cervical vertebra, initial encounter for closed 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.
