Lumbosacral root lesions, not elsewhere classified

This code signifies nerve damage or dysfunction affecting the lumbosacral nerve roots, which originate from the lower spinal cord and innervate the lower extremities and pelvic region. It encompasses conditions like radiculopathy, compression, or inflammation of these nerve roots that are not attributable to a specific, more precisely classified etiology.

Use this code for diagnoses such as lumbosacral radiculopathy, sciatica, or nerve root compression when the underlying cause (e.g., disc herniation, spondylosis, trauma) is not specified or is not the primary diagnosis. Documentation should clearly indicate involvement of the lumbosacral nerve roots and the absence of a more specific diagnostic code.

• Do not use if a more specific cause for the lumbosacral root lesion is documented (e.g., disc displacement, spinal stenosis).
• Consider sequencing this code after a more definitive diagnosis if the root lesion is a manifestation of another condition.
• Distinguish from peripheral neuropathies, which involve nerves outside the spinal roots.
