M46.55
ICD-10-CMThis code signifies an inflammatory condition of the vertebrae in the thoracolumbar spine (T1-L5 region) caused by an infectious agent other than those specified in more granular codes. It represents an infection of the spinal column itself, distinct from discitis or osteomyelitis without spondylopathy.
Apply this code when documentation specifies an infective spondylopathy affecting the thoracolumbar region, and the specific pathogen is not identified or is not one for which a more precise code exists (e.g., tuberculous spondylitis). Supporting documentation should clearly indicate an infectious etiology and involvement of the vertebral body.
