    ICD-10-CM Code For Other Disorders Of Optic Nerve And Visual Pathways: Group Overview

    The International Classification of Diseases, Tenth Revision, Clinical Modification (ICD-10-CM) code group H47 includes other disorders of the optic nerve and visual pathways, covering secondary optic neuropathies, visual pathway lesions, and other specified optic nerve disorders that affect vision and visual processing. These ICD-10-CM diagnosis codes are used to document clinical scenarios such as unilateral or bilateral visual loss, optic nerve inflammation or degeneration, and lesions of the optic tract or radiations, capturing disease severity and anatomic involvement. Accurate coding within the ICD-10-CM H47 group supports proper claim adjudication, complete clinical documentation, and appropriate reimbursement.

    ICD-10-CM H47: Other Disorders Of Optic [2nd] Nerve And Visual Pathways Overview

    This group represents diagnoses affecting the optic nerve and visual pathways, including secondary and other specified disorders of the second cranial nerve and central visual pathways. These conditions target the visual sensory system and can cause visual field defects, vision loss, or other neuro-ophthalmologic impairments. Accurate coding matters for clinical communication and supports reimbursement by documenting disease specificity and severity.

    When to Use

    Use a code from this group when the primary clinical problem is a disorder of the optic nerve or central visual pathways documented by the clinician. Select the code that reflects the specific anatomic site, laterality, and etiology when available to capture clinical detail and severity.

    Typical Clinical Scenarios

    • A middle-aged patient presents to the emergency department with sudden, painless loss of vision in one eye over several hours after awakening. Neuro-ophthalmic exam reveals a relative afferent pupillary defect and pale, edematous optic disc consistent with acute ischemic optic neuropathy; emergent evaluation rules out giant cell arteritis. A diagnosis from this group is assigned because the pathology involves the optic nerve and acute visual pathway compromise. Typical codes: H47.011, H47.019
    • An adult with long-standing multiple sclerosis comes to clinic for worsening blurred vision and internuclear ophthalmoplegia; prior records document chronic optic nerve atrophy in the affected eye from previous optic neuritis episodes. A code from this group is used to capture chronic degenerative change of the optic nerve as a comorbidity affecting current visual function and rehabilitation planning. Typical codes: H47.21, H47.22
    • A patient is seen in outpatient follow-up after orbital decompression surgery for thyroid eye disease and now has persistent optic nerve compression with progressive visual field defects on automated perimetry. The clinician documents compressive optic neuropathy affecting the visual pathways related to the orbital process, necessitating coding for optic nerve disorder complicating the orbital condition. Typical codes: H47.621, H47.629
