Connective tissue stenosis of neural canal of sacral region

This code signifies a narrowing of the sacral spinal canal due to an overgrowth or thickening of connective tissues. This stenosis can compress the sacral nerves, leading to various neurological symptoms in the lower extremities, perineum, or pelvic region.

Apply this code when documentation explicitly states sacral neural canal stenosis caused by connective tissue involvement. This diagnosis is typically supported by imaging studies (e.g., MRI, CT) demonstrating the narrowing and clinical findings consistent with sacral radiculopathy or cauda equina syndrome.

• Ensure the documentation specifies "connective tissue" as the etiology of the stenosis, not bone or disc.
• Do not confuse with general sacral stenosis (M48.08) if the specific cause is identified as connective tissue.
• Consider sequencing this code with codes for associated neurological symptoms (e.g., radiculopathy, pain) if present.
