Wallenberg Syndrome, also known as lateral medullary syndrome, is a neurological condition caused by a stroke or blockage in the vertebral or posterior inferior cerebellar artery. It is characterized by symptoms such as dizziness, difficulty swallowing, hoarseness, and facial numbness. The ICD-10 code for Wallenberg Syndrome is G46.4, while the corresponding ICD-9 code is 433.81. Proper diagnosis and treatment are crucial for managing this condition effectively.
Wallenberg syndrome, also known as lateral medullary syndrome or posterior inferior cerebellar artery syndrome, is a neurological condition caused by a disruption in blood flow to the lateral medulla oblongata in the brainstem. This leads to a range of symptoms affecting multiple systems in the body.
The ICD-10 code for Wallenberg syndrome is G46.4. This code falls under the broader category of "Vascular syndromes of brain in cerebrovascular diseases" in the ICD-10 coding system. It specifically denotes the lateral medullary syndrome caused by vascular issues.
In the previous ICD-9 coding system, Wallenberg syndrome was classified under code 434.91, which falls under the category of "Cerebral artery occlusion, unspecified with cerebral infarction". However, it is important to note that the ICD-9 coding system is no longer in use as it has been replaced by the ICD-10 system.
Wallenberg syndrome typically presents with a variety of symptoms including vertigo, dizziness, difficulty swallowing, hoarseness, facial numbness or pain, loss of pain and temperature sensation on one side of the face, impaired coordination, and nystagmus (involuntary eye movements). These symptoms result from the disruption of various cranial nerves and brainstem structures.
Diagnosis of Wallenberg syndrome is usually based on clinical presentation and confirmed through imaging studies such as magnetic resonance imaging (MRI) or computed tomography (CT) scans. Treatment primarily focuses on managing the underlying cause, such as blood thinners for clot-related cases or addressing other vascular issues.
In conclusion, Wallenberg syndrome is a neurological condition with the ICD-10 code G46.4, related to vascular syndromes of the brain. The previous ICD-9 code for Wallenberg syndrome was 434.91.
