About S12

S12 is the ICD-10-CM diagnosis code for fracture of cervical vertebra and other parts of neck. It belongs to block S10-S19 (injuries to the neck) and chapter 19 (injury, poisoning and certain other consequences of external causes). It is a header code, so it can't be reported by itself; one of its 9 subcodes must be used instead.

To report this condition, pick the subcode that matches the documentation: S12.0 (vertebra), S12.1 (vertebra), S12.2 (vertebra), S12.3 (vertebra), S12.4 (vertebra), S12.5 (vertebra), S12.6 (vertebra), S12.8 (neck) and 1 more.

Code first: any associated cervical spinal cord injury (S14.0, S14.1-).

It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
