Osseous stenosis of neural canal of lumbar region

This code signifies a narrowing of the spinal canal within the lumbar spine due to bony overgrowth or structural changes. This compression can impinge upon the spinal cord or nerve roots, leading to neurological symptoms. It specifically refers to the osseous (bony) component of the stenosis.

Apply this code when documentation explicitly states lumbar spinal canal stenosis caused by bony structures, such as osteophytes, thickened laminae, or facet hypertrophy. This diagnosis is typically supported by imaging studies (e.g., MRI, CT scan) demonstrating the osseous narrowing and its location.

• Differentiate from soft tissue stenosis (e.g., ligamentum flavum hypertrophy) which would be coded differently.
• Ensure the documentation specifies the lumbar region; stenosis in other spinal regions has different codes.
• Always look for associated neurological symptoms (e.g., radiculopathy, claudication) which may require additional codes.
