Oth nondisp fx of fourth cervical vertebra, init for opn fx

This code signifies a fracture of the fourth cervical vertebra that is not displaced, meaning the bone fragments remain in their normal anatomical alignment. The "open fracture" designation indicates that the skin and soft tissues overlying the fracture site have been compromised, exposing the bone to the external environment. This is an initial encounter, meaning the patient is receiving active treatment for the fracture.

Use this code for patients presenting with a newly diagnosed, nondisplaced fracture of the C4 vertebra where there is an associated open wound. Documentation must clearly state "nondisplaced," specify the "fourth cervical vertebra," and explicitly mention "open fracture" or describe an open wound communicating with the fracture site. This code is appropriate for the first visit for treatment of this specific injury.

• Ensure documentation specifies "nondisplaced" to differentiate from displaced fractures (S12.321-).
• Verify the specific cervical vertebra involved; this code is only for C4.
• Confirm "open fracture" status; if the skin is intact, a closed fracture code (S12.39XA) would be more appropriate.
