S12.0 — Fracture of first cervical vertebra
Is S12.0 billable?
No — S12.0 is a non-billable header code. S12.0 groups more specific codes and cannot be submitted on a claim. A valid ICD-10-CM code must be reported at the highest level of specificity available in its branch. Select one of the 60 billable codes beneath S12.0.

Code first — inherited from S12
The underlying condition below must be sequenced before S12.0. S12.0 describes a manifestation and cannot be the principal or first-listed diagnosis.
Use additional code — inherited from Chapter 19
Report an additional code alongside S12.0 to fully describe the condition. S12.0 is sequenced first.
- code to identify any retained foreign body, if applicable (Z18.-)
Excludes2 — not included here — inherited from Chapter 19
The conditions below are not part of S12.0, but a patient may have both at the same time. When documentation supports it, S12.0 and the excluded code may both be reported.
Excludes2 — not included here — inherited from S10-S19
The conditions below are not part of S12.0, but a patient may have both at the same time. When documentation supports it, S12.0 and the excluded code may both be reported.

How long has S12.0 existed?
S12.0 has been in ICD-10-CM since at least FY2016, the earliest fiscal year on record here.
Derived from the official order files for FY2016–FY2026. FY2017 and FY2020 publish no order file, so those years are not covered.
