M46.05
ICD-10-CMThis code signifies an inflammatory or degenerative condition affecting the entheses (sites where tendons, ligaments, or joint capsules attach to bone) within the thoracolumbar spine. It specifically points to pathology at these attachment points, rather than a primary disc or vertebral body issue.
Utilize this code when documentation explicitly states enthesopathy affecting the thoracic, lumbar, or lumbosacral regions of the spine. This diagnosis is often associated with spondyloarthropathies or other inflammatory conditions, but can also be degenerative. Supporting documentation should detail the specific spinal region involved.
