Osseous stenosis of neural canal of rib cage

This code describes a narrowing of the neural canal within the rib cage due to bone abnormalities. This osseous stenosis can compress the spinal cord or nerve roots in the thoracic region, leading to neurological symptoms. It specifically refers to a structural narrowing caused by bone, rather than soft tissue.

Use this code for patients diagnosed with a bony constriction of the neural canal affecting the thoracic spine, as documented by imaging studies such as MRI or CT scans. This diagnosis is typically made when a patient presents with myelopathy or radiculopathy symptoms localized to the thoracic region, and imaging confirms osseous impingement.

• Ensure documentation clearly specifies "osseous" or "bony" stenosis to differentiate from other causes of narrowing.
• Do not confuse this with spinal stenosis in other regions (e.g., cervical or lumbar), which have different codes.
• Code any associated neurological deficits (e.g., myelopathy, radiculopathy) separately as secondary diagnoses.
