A vertebral fracture described as "lateral mass" should be coded to which part of the vertebra?

A vertebral fracture described specifically as involving the "lateral mass" refers to a distinct anatomical structure of the vertebra, particularly found within the cervical spine. The lateral masses are the large, lateral portions of the vertebrae that allow for articulation with adjacent vertebrae, and they play a critical role in stability and movement.

Understanding that the lateral mass is not part of the vertebral body, spinous process, or transverse process is essential. The vertebral body is the central portion of the vertebra, while the spinous process is the bony projection on the posterior side. The transverse process extends laterally from the vertebra but does not encompass the concept of lateral mass.

Therefore, coding a fracture of the lateral mass directly pertains to the pedicle area, which supports the structure of the lateral masses and is critical in terms of neural and vascular considerations in spinal injuries. Thus, the lateral mass is most accurately associated with the pedicle in this context, making it the correct choice for coding the type of vertebral fracture described.
