Oth nondisplaced dens fracture, init for opn fx

This code signifies a fracture of the dens (odontoid process) of the C2 vertebra that is not displaced, meaning the bone fragments remain in their anatomical alignment. It specifically indicates an open fracture, where the skin and soft tissue are compromised, exposing the bone. This is the initial encounter for treatment of the injury.

Use this code for patients presenting with a newly diagnosed, non-displaced open fracture of the C2 dens. Documentation should clearly state "nondisplaced," "open fracture," and specify the dens or odontoid process as the fracture site. This code is appropriate for the initial surgical or medical management of the injury.

• Ensure documentation explicitly states "nondisplaced" and "open fracture" to support this specific code.
• Verify laterality (left/right) is not applicable for dens fractures, as it is a midline structure.
• Do not confuse with displaced dens fractures (S12.13-) or closed fractures (S12.12-).
