Unsp nondisp fx of second cervical vertebra, init for opn fx

This code signifies a fracture of the second cervical vertebra (C2) that is not displaced, meaning the bone fragments are still in their normal anatomical alignment. The "unspecified" nature indicates that the specific type of C2 fracture (e.g., odontoid, hangman's) is not documented. This particular instance involves an open fracture, where the skin and soft tissue have been broken, exposing the bone.

Use this code for the initial encounter of a patient presenting with an open, nondisplaced fracture of the C2 vertebra when the specific type of C2 fracture is not documented by the provider. Documentation should clearly state "open fracture," "nondisplaced," and "second cervical vertebra" or "C2." This code is appropriate when the patient is receiving active treatment for the fracture.

• Ensure documentation specifies "open fracture" and "nondisplaced." If the fracture is closed, a different code from the S12.101- series would be appropriate.
• If the specific type of C2 fracture (e.g., odontoid, traumatic spondylolisthesis) is documented, a more specific code should be selected.
• The "B" seventh character indicates an initial encounter for active treatment; subsequent encounters would require different seventh characters.
