Oth nondisplaced dens fracture, init for clos fx

This code signifies a fracture of the odontoid process (dens) of the C2 vertebra that is not displaced, meaning the bone fragments remain in their anatomical alignment. It specifically applies to the initial treatment phase of a closed fracture, where the skin over the fracture site is intact.

Apply this code for patients presenting with a newly diagnosed, nondisplaced dens fracture that is being treated for the first time. Documentation should clearly state "nondisplaced dens fracture" and confirm the fracture is closed and in its initial phase of care.

• Ensure documentation specifies "nondisplaced" to differentiate from displaced fractures (S12.122-).
• Verify the encounter is for the initial treatment; subsequent care would use a different seventh character (D, G, K, P, S).
• Confirm the fracture is "closed"; open fractures have distinct codes (e.g., S12.12XA).
