Connective tissue stenosis of neural canal of pelvic region

This code signifies a narrowing of the spinal canal within the pelvic region due to an overgrowth or thickening of connective tissues. This stenosis can compress the neural structures (spinal cord or nerve roots) traversing this area, leading to neurological symptoms. It specifically points to a non-osseous cause of the canal narrowing.

Apply this code when documentation clearly indicates a diagnosis of spinal canal stenosis in the sacral or coccygeal region, explicitly attributed to connective tissue involvement. Supporting documentation would typically include imaging reports (MRI, CT) detailing soft tissue hypertrophy or fibrosis causing canal narrowing, alongside physician notes describing associated neurological deficits.

• Differentiate from osseous stenosis (e.g., M48.07) where bone or disc material is the primary cause of narrowing.
• Ensure the documentation specifies "connective tissue" as the etiology, not just general "stenosis."
• Consider sequencing this code with codes for any associated neurological symptoms (e.g., sciatica, neurogenic claudication) if present.
