    ICD-10-CM Code For Nerve Root And Plexus Disorders: Group Overview

    The International Classification of Diseases, Tenth Revision, Clinical Modification (ICD-10-CM) code group G54 includes disorders of nerve roots and nerve plexuses such as radiculopathy, plexopathy, and compressive or traumatic neuropathies that affect peripheral nerve function. These ICD-10-CM diagnosis codes are used to document clinical presentations including pain, sensory deficits, motor weakness, and autonomic involvement to capture disease severity and anatomic localization. Accurate coding within the ICD-10-CM G54 group supports proper claim adjudication and complete clinical documentation for appropriate reimbursement.

    ICD-10-CM G54: Nerve Root And Plexus Disorders Overview

    The ICD-10-CM G54 group includes diagnoses affecting peripheral nerves, nerve roots, and nerve plexuses supplying the limbs and trunk. These conditions target the peripheral nervous system and can cause pain, sensory loss, motor weakness, or autonomic dysfunction. Accurate coding is important for complete clinical documentation and supports appropriate reimbursement for services tied to these neurologic conditions.

    When to Use

    Codes from this group are used when documentation identifies clinical findings attributable to a nerve root or plexus, such as dermatomal pain, weakness in a myotomal distribution, or localized sensory loss. These codes are selected when the clinician has specified the affected nerve root or plexus and the condition is the focus of care or affects management decisions.

    Typical Clinical Scenarios

    • An adult presents to the emergency department with sudden-onset severe radicular pain radiating from the neck into the right arm after lifting a heavy object, accompanied by numbness in the thumb and weakness with wrist extension on exam. Imaging shows a cervical disc herniation compressing the C7 nerve root and the clinician documents an acute symptomatic nerve root compression requiring urgent pain control and neurosurgical consultation; a nerve root disorder diagnosis from this group is assigned to capture the radiculopathy. Typical codes: G54.0, G54.1
    • A middle-aged office worker reports months of progressive burning pain, paresthesia, and intermittent weakness in the distribution of the brachial plexus following a motor vehicle collision; symptoms have persisted despite conservative therapy. The outpatient neurologist documents a chronic plexopathy affecting the brachial plexus as the primary cause of the patient’s functional limitations and orders electrodiagnostic testing; a plexus disorder code from this group is used to describe the chronic neuropathic condition. Typical codes: G54.2, G54.4
    • An elderly patient with diabetes is admitted for a diabetic foot ulcer and is noted to have longstanding lumbar radiculopathy that complicates mobility and wound care, with chronic leg pain and sensory loss in an L5 distribution. The radiculopathy is documented as a comorbidity that affects rehabilitation and discharge planning, so a nerve root disorder code from this group is assigned to reflect the chronic nerve involvement influencing care. Typical codes: G54.6, G54.9
