Subluxation stenosis of neural canal of lumbar region

This code describes a narrowing of the spinal canal in the lumbar region caused by a partial dislocation or misalignment of one or more vertebrae. This subluxation leads to compression of the neural structures within the canal, such as the spinal cord or nerve roots.

Use this code when documentation clearly indicates lumbar spinal canal stenosis directly resulting from vertebral subluxation. This diagnosis is typically supported by imaging studies (e.g., MRI, CT) demonstrating both subluxation and neural canal narrowing, along with clinical findings consistent with nerve compression.

• Ensure documentation specifies the lumbar region; do not use for other spinal segments.
• Distinguish from other causes of stenosis (e.g., degenerative, congenital) if subluxation is not the primary etiology.
• Consider sequencing with codes for associated neurological symptoms (e.g., radiculopathy, myelopathy) if present.
