Connective tiss stenosis of neural canal of lower extremity

This code signifies a narrowing of the spinal canal or neural foramina within the lower extremity region, specifically caused by an overgrowth or thickening of connective tissues. This stenosis can compress nerves, leading to symptoms such as pain, numbness, or weakness in the leg or foot.

Apply this code when documentation explicitly states connective tissue is the cause of neural canal stenosis affecting the lower extremity. This is typically supported by imaging reports (MRI, CT) detailing the anatomical narrowing and physician notes describing corresponding neurological symptoms in the leg.

• Differentiate from osseous or discogenic stenosis; this code is specific to connective tissue involvement.
• Ensure the documentation clearly links the stenosis to the lower extremity, not just the lumbar spine in general.
• Consider sequencing this code after a primary diagnosis describing the patient's presenting symptoms (e.g., radiculopathy, claudication).
