    ICD-10-CM Code For Other Disorders Of Peripheral Nervous System: Group Overview

    The International Classification of Diseases, Tenth Revision, Clinical Modification (ICD-10-CM) code group G64 includes a range of other disorders of the peripheral nervous system, such as miscellaneous polyneuropathies and peripheral nerve conditions not classified in other categories. These ICD-10-CM diagnosis codes are used to document clinical presentations involving peripheral nerve dysfunction, variations in severity, and multisystem involvement when applicable. Accurate coding within the ICD-10-CM G64 group supports proper claim adjudication and complete clinical documentation and appropriate reimbursement.

    ICD-10-CM G64: Other Disorders Of Peripheral Nervous System Overview

    This group represents miscellaneous disorders affecting the peripheral nervous system, including various other polyneuropathies and peripheral nerve conditions not classified elsewhere. It targets peripheral nerves and associated sensory, motor, or autonomic dysfunction. Accurate coding is important to ensure detailed clinical records and appropriate reimbursement for services related to diagnosis and management.

    Use a code from this group when the clinical documentation identifies an other specified or unspecified peripheral nervous system disorder not covered by more specific codes. Select the most specific code available based on documented symptoms, nerve involvement, and any noted etiologies.

    Typical Clinical Scenarios

    • An older adult with progressive symmetric distal weakness and numbness over months, with diminished ankle reflexes and a history of long-standing diabetes presents to neurology for evaluation of gait instability and recurrent falls. Electrophysiologic testing shows a length-dependent sensorimotor peripheral neuropathy not explained by common metabolic causes, and additional workup excludes vitamin deficiency and autoimmune neuropathies; a code from this group is assigned for a chronic peripheral nerve disorder beyond typical diabetic neuropathy. Typical codes: G64
    • A middle-aged patient undergoing evaluation for persistent unexplained paresthesias and motor deficits after chemotherapy for malignancy presents to oncology clinic; neurologic exam reveals multifocal peripheral nerve involvement and EMG/nerve conduction studies suggest a toxic or treatment-related polyneuropathy. Because the neuropathic findings are attributable to peripheral nerve disorder other than principal causes, a code in this group is used to document the disorder as a comorbidity affecting treatment decisions. Typical codes: G64
    • A young adult is seen in the emergency department with subacute onset of asymmetric limb weakness and sensory loss following a recent infection; initial workup raises concern for an atypical peripheral neuropathy not meeting criteria for Guillain-Barré syndrome, and specialists document an other specified disorder of the peripheral nervous system pending further testing. An acute but non-classic peripheral nerve disorder code from this group is assigned for hospital record and early management. Typical codes: G64
