Intervertebral disc stenosis of neural canal of low extrm

This code describes the narrowing of the spinal canal within the lumbar or sacral region, specifically impacting the nerves that innervate the lower extremities. This compression can lead to symptoms such as pain, numbness, weakness, or tingling radiating down the leg.

Use this code when documentation clearly indicates intervertebral disc stenosis affecting the neural canal, with symptoms or findings localized to the lower extremities. This diagnosis is typically supported by imaging studies (MRI, CT) showing disc-related compression and clinical notes detailing lower extremity neurological deficits.

• Ensure the documentation specifies "intervertebral disc" as the cause of the stenosis, distinguishing it from other etiologies.
• Verify that the symptoms or neurological findings are explicitly linked to the lower extremities.
• Consider sequencing this code after any underlying disc disorder (e.g., M51.3- for other intervertebral disc degeneration) if applicable and documented as the primary cause.
