Conn tiss and disc stenosis of intvrt foramina of low extrm

This code signifies the narrowing of the intervertebral foramen in the lumbar or sacral spine due to issues with connective tissue or intervertebral discs, leading to compression of nerve roots that supply the lower extremities. This stenosis can result in radicular symptoms such as pain, numbness, or weakness radiating into the leg or foot.

Apply this code when documentation explicitly states connective tissue or disc-related stenosis of the intervertebral foramen affecting the lower extremity, typically in the lumbar or sacral region. Supporting documentation includes MRI or CT reports confirming foraminal narrowing and clinical notes describing corresponding lower extremity radiculopathy.

• Ensure the documentation specifies the cause of the stenosis as connective tissue or disc, not just general foraminal stenosis.
• Verify that symptoms are localized to the lower extremity to differentiate from cervical or thoracic involvement.
• Do not confuse with M48.06 (spinal stenosis, lumbar region) unless the specific foraminal involvement and cause are detailed.
