    ICD-10-CM Code For Nerve Root And Plexus Compressions In Diseases Classified Elsewhere: Group Overview

    The International Classification of Diseases, Tenth Revision, Clinical Modification (ICD-10-CM) code group G55 includes compressive lesions of nerve roots and nerve plexuses that occur in the context of diseases classified elsewhere, such as radiculopathy or plexopathy secondary to tumors, inflammatory disorders, or other systemic conditions. These ICD-10-CM diagnosis codes are used to document nerve compression attributable to underlying diseases, capturing clinical complexity, anatomic site involvement, and associated neurologic deficits. Accurate coding within the ICD-10-CM G55 group supports proper claim adjudication, complete clinical documentation, and appropriate reimbursement.

    ICD-10-CM G55: Nerve Root And Plexus Compressions In Diseases Classified Elsewhere Overview

    This group represents diagnoses of nerve root and nerve plexus compressions that occur as manifestations of other underlying diseases rather than primary nerve disorders. It targets peripheral nervous system involvement such as radiculopathy or plexopathy resulting from systemic or localized conditions. Accurate coding matters for complete clinical documentation and supports appropriate claim adjudication and reimbursement.

    When to Use

    Use a code from this group when documentation indicates nerve root or plexus compression is secondary to a disease classified elsewhere and the underlying cause is identified. These codes are applied to capture the anatomic site of compression and any related neurologic deficits as part of the overall diagnostic coding.

    Typical Clinical Scenarios

    • An elderly patient with progressive neck pain and radiating numbness along the lateral forearm and thumb after months of cervical spondylosis presents to an outpatient neurology clinic for worsening arm weakness and sensory loss; imaging shows cervical disk osteophyte complex compressing the C6 nerve root attributable to an underlying degenerative spine disease, so a code from this group is assigned to capture nerve root compression occurring in the context of that other disorder. Typical codes: G55
    • A middle-aged diabetic patient admitted from the emergency department for acute severe left-sided axillary pain with immediate onset of numbness and paresthesias after a fall, where evaluation reveals traction injury to the brachial plexus in the setting of recent shoulder trauma; clinicians assign a code from this group to document plexus compression as a consequence of the traumatic event and coexisting musculoskeletal injury. Typical codes: G55
    • A cancer patient receiving radiation therapy to the thoracic inlet develops new progressive interscapular neuropathic pain and hand weakness over weeks; electromyography and imaging indicate radiation-induced brachial plexopathy with nerve root involvement related to the underlying malignancy, and a code from this group is used to identify nerve/plexus compression secondary to disease elsewhere. Typical codes: G55
