ICD-10: H47

The ICD-10 code H47 pertains to "Other disorders of optic [2nd] nerve and visual pathways." This classification encompasses a variety of conditions affecting the optic nerve and the visual pathways, which are crucial for transmitting visual information from the retina to the brain. Below is a detailed clinical description and relevant information regarding this code.

Clinical Description

Overview of H47

The H47 code is part of the broader category of disorders affecting the optic nerve and visual pathways, which are classified under codes H46 to H48. These disorders can result from various etiologies, including congenital anomalies, inflammatory conditions, traumatic injuries, and degenerative diseases. The optic nerve is essential for vision, and any disorder affecting it can lead to significant visual impairment.

Common Conditions Associated with H47

1. Optic Neuritis: Inflammation of the optic nerve, often associated with multiple sclerosis, leading to vision loss and pain.
2. Optic Atrophy: A condition characterized by the degeneration of the optic nerve fibers, which can result from various causes, including ischemia, trauma, or chronic glaucoma.
3. Crater-like Holes of the Optic Disc: This condition, classified under H47.391-393, involves the formation of crater-like depressions in the optic disc, which can indicate underlying pathology.
4. Other Visual Pathway Disorders: This may include conditions affecting the optic chiasm, optic tracts, and other components of the visual pathway, leading to visual field defects or other visual disturbances.

Symptoms

Patients with disorders classified under H47 may experience a range of symptoms, including:
- Blurred or decreased vision
- Visual field loss
- Color vision deficiencies
- Pain with eye movement (particularly in optic neuritis)
- Changes in visual perception

Diagnosis

Diagnosis of disorders under H47 typically involves:
- Clinical Examination: A thorough eye examination, including visual acuity tests and assessment of the optic nerve head.
- Visual Fields Testing: This is crucial for identifying specific visual field defects associated with optic nerve disorders[5][7].

The ICD-10 code H47 pertains to "Other disorders of optic nerve and visual pathways," which encompasses a variety of conditions affecting the optic nerve and the pathways that transmit visual information from the eye to the brain. Diagnosing disorders under this code involves a comprehensive evaluation based on clinical criteria, patient history, and diagnostic testing. Below are the key criteria and considerations used in the diagnosis of conditions classified under H47.

Clinical Evaluation

Patient History

• Symptom Assessment: Patients typically present with symptoms such as vision loss, visual field defects, or changes in color perception. A detailed history of the onset, duration, and progression of these symptoms is crucial.
• Medical History: A thorough review of the patient's medical history, including any previous eye conditions, systemic diseases (like diabetes or hypertension), and neurological disorders, is essential.

Physical Examination

• Ophthalmic Examination: An eye examination is performed to assess visual acuity, pupillary response, and ocular motility. This may include checking for signs of optic nerve swelling or pallor.
• Visual Field Testing: This helps identify any defects in the visual field that may indicate damage to the optic nerve or visual pathways.

Diagnostic Testing

Imaging Studies

• Optical Coherence Tomography (OCT): This non-invasive imaging technique provides cross-sectional images of the retina and can help assess the thickness of the retinal nerve fiber layer, which may be indicative of optic nerve damage.
