G54.8
ICD-10-CMThis code signifies nerve root or plexus disorders that are not specifically classified elsewhere. It encompasses conditions affecting the spinal nerve roots (cervical, thoracic, lumbar, sacral) or the major nerve plexuses (brachial, lumbosacral) when a more precise ICD-10-CM code is unavailable. These disorders often manifest with pain, sensory disturbances, or motor weakness in the distribution of the affected nerves.
Apply this code when documentation clearly indicates a nerve root or plexus disorder, but the specific etiology or anatomical location does not have a dedicated, more granular code. This is appropriate for conditions like idiopathic plexopathy, or when the physician's diagnosis is "other nerve root compression" without further specificity. Supporting documentation should detail the affected nerve roots or plexus and rule out more specific diagnoses.
