Other nerve root and plexus disorders

This code represents various conditions affecting nerve roots or plexuses that are not specifically classified elsewhere. It encompasses a range of neurological disorders characterized by pain, weakness, sensory disturbances, or autonomic dysfunction originating from these peripheral nervous system structures. This includes conditions like brachial plexopathy, lumbosacral plexopathy, or radiculopathies not due to disc herniation or other specified causes.

Use this code when documentation clearly indicates a disorder of a nerve root or plexus, but a more specific ICD-9-CM code (e.g., for disc-related radiculopathy or specific inflammatory plexopathies) is not applicable or available. This code is appropriate for diagnoses such as "brachial plexitis NOS," "lumbosacral plexopathy of unknown etiology," or "cervical radiculopathy, unspecified cause." Documentation should specify the affected nerve root or plexus and the nature of the disorder.

• Always attempt to find a more specific code if the documentation provides enough detail (e.g., specific cause of plexopathy or radiculopathy).
• Do not use this code for conditions clearly identified as mononeuropathies or polyneuropathies affecting distal nerves.
• Consider sequencing this code as a primary diagnosis if it is the main reason for the encounter, or as a secondary diagnosis if it is a co-morbidity.
