Lumbosacral plexus disorders

This code signifies a condition affecting the network of nerves originating from the lumbar and sacral spinal cord segments, which innervate the lower limbs and pelvic region. It encompasses various etiologies leading to dysfunction of these nerve roots and their branches.

Apply this code when documentation indicates a diagnosis of lumbosacral plexopathy, such as from trauma, compression, inflammation, or neoplastic infiltration. Supporting documentation often includes neurological examination findings, electromyography (EMG), nerve conduction studies (NCS), and imaging results confirming plexus involvement.

• Differentiate from radiculopathy (G54.x codes) which affects individual nerve roots, whereas this code applies to the plexus.
• Specify laterality (e.g., G54.11 for right, G54.12 for left) if documented.
• Code any underlying cause or associated conditions, such as malignancy or diabetes, as additional diagnoses.
