Connective tissue stenosis of neural canal of rib cage

This code signifies a narrowing of the spinal canal within the thoracic region, specifically caused by an overgrowth or thickening of connective tissues. This stenosis can compress the spinal cord or nerve roots, leading to neurological symptoms.

Use this code when documentation clearly indicates thoracic spinal canal stenosis due to connective tissue involvement. This diagnosis is typically supported by imaging studies (e.g., MRI, CT scan) demonstrating the narrowing and a physician's assessment attributing it to connective tissue proliferation.

• Differentiate from stenosis due to disc herniation or osteophyte formation; those have different codes.
• Ensure the documentation specifies "connective tissue" as the etiology, not just general thoracic stenosis.
• Consider sequencing with codes for associated neurological symptoms (e.g., myelopathy, radiculopathy) if present.
