Intvrt disc stenosis of neural canal of thoracic region

This code describes the narrowing of the spinal canal within the thoracic spine due to an intervertebral disc abnormality. This compression can impinge on the spinal cord or nerve roots, leading to neurological symptoms.

Use this code when documentation specifies central canal stenosis in the thoracic region caused by a disc. This diagnosis is typically supported by imaging studies (e.g., MRI, CT) showing disc protrusion, herniation, or degeneration contributing to the narrowing.

• Differentiate from stenosis caused by bony overgrowth (e.g., M48.04).
• Specify laterality if documented for nerve root involvement, though this code is for the central canal.
• Always review imaging reports and physician notes to confirm the etiology of the stenosis.
