Lumbosacral plexus lesions

This code signifies damage or dysfunction affecting the network of nerves originating from the lumbar and sacral spinal cord segments. These lesions can result in sensory, motor, and autonomic deficits in the lower extremities, perineum, and pelvic organs.

Apply this code when documentation specifies a diagnosis of a lumbosacral plexus injury, neuropathy, or entrapment. This includes conditions like lumbosacral plexopathy due to trauma, compression, inflammation, or tumor infiltration. Supporting documentation should clearly identify the lumbosacral plexus as the affected anatomical site.

• Differentiate from radiculopathy (nerve root involvement) or peripheral mononeuropathies, which affect individual nerves distal to the plexus.
• Always look for an underlying cause or etiology to code concurrently, if known and documented (e.g., trauma, neoplasm, diabetes).
• Consider laterality if specified in the documentation (e.g., right, left, bilateral).
