Other spondylosis with myelopathy

M47.10 identifies degenerative spinal disease (spondylosis) that has produced spinal cord compression and dysfunction (myelopathy) at a location not documented in the medical record.

Degenerative spondylotic disease of the occipito-atlanto-axial region (C0–C2) producing spinal cord compression and myelopathic neurological deficits — not attributable to anterior spinal artery or vertebral artery compression syndromes (those fall under M47.0x).

Degenerative disease of the cervical spine (C1–C7 region) in which spondylotic changes — osteophytes, facet arthrosis, disc degeneration, or ligamentous hypertrophy — compress the spinal cord and produce myelopathy.

Degenerative spondylotic changes at the cervicothoracic junction (C7–T1 region) that have progressed to the point of causing spinal cord compression and resultant myelopathy.

Spondylosis of the thoracic spine causing spinal cord compression and resultant myelopathy — a chronic, degenerative condition involving disc degeneration, facet joint arthrosis, and osteophyte formation at the thoracic vertebral levels.

Degenerative spinal disease at the thoracolumbar junction (T12-L1) causing compression or dysfunction of the spinal cord — classified as 'other' spondylosis to distinguish it from anterior spinal artery compression spondylosis (M47.01x).

Degenerative spinal disease of the lumbar region causing spinal cord compression with documented myelopathy — classified under the M47.1 (other spondylosis with myelopathy) parent category.
