Spinal stenosis

Spinal stenosis with no documented spinal region — the fallback code when the narrowing of the spinal canal is confirmed but the specific vertebral level or region is absent from the record.

Spinal stenosis localized to the occipito-atlanto-axial region — the articulation between the occiput, atlas (C1), and axis (C2) — where narrowing of the spinal canal compresses neural or vascular structures at the craniocervical junction.

M48.02 identifies pathological narrowing of the spinal canal within the cervical region (C2–C7), which can compress the spinal cord or nerve roots and produce myelopathy, radiculopathy, or both.

M48.03 identifies spinal stenosis localized to the cervicothoracic region — the C7–T1 junction where the cervical spine transitions into the thoracic spine — resulting in narrowing of the spinal canal at that specific anatomical boundary.

Narrowing of the spinal canal within the thoracic vertebral segment, encompassing both stenosis with and without associated myelopathy.

Spinal stenosis occurring at the thoracolumbar junction — the transition zone between the thoracic and lumbar spine, roughly spanning the T10–L2 vertebral levels — where narrowing of the spinal canal compresses neural structures.

M48.07 identifies spinal stenosis localized to the lumbosacral region — the junction where the lumbar spine meets the sacrum — involving narrowing of the spinal canal at that transitional segment.

Narrowing of the spinal canal at the sacral or sacrococcygeal level, compressing nerve roots in the terminal spinal column.
