Clonic hemifacial spasm, unspecified
ICD-10 G51.39 is a billable code used to indicate a diagnosis of clonic hemifacial spasm, unspecified.
Clonic hemifacial spasm is characterized by involuntary, intermittent contractions of the muscles on one side of the face, typically affecting the eyelid and surrounding facial muscles. This condition is often caused by irritation or compression of the facial nerve (cranial nerve VII), which can occur due to various factors such as vascular compression, tumors, or multiple sclerosis. Patients may experience episodes that can be triggered by stress, fatigue, or bright lights. The spasms can lead to significant discomfort and social embarrassment, impacting the patient's quality of life. Diagnosis is primarily clinical, based on the characteristic symptoms and physical examination. Electromyography (EMG) may be utilized to assess the electrical activity of the facial muscles and confirm the diagnosis. Treatment options include botulinum toxin injections, which can help alleviate symptoms by temporarily paralyzing the affected muscles, and surgical interventions in more severe cases. Understanding the underlying causes and appropriate management strategies is crucial for effective treatment.
Detailed neurological examination findings, including muscle strength and reflexes.
Patients presenting with unilateral facial spasms, especially after a history of trauma or vascular issues.
Ensure to document any imaging studies or EMG results that support the diagnosis.
Thorough history of facial symptoms and any previous treatments attempted.
Patients with facial nerve compression due to tumors or vascular anomalies.
Document surgical interventions or referrals for surgical evaluation if applicable.
Used for patients receiving botulinum toxin injections for hemifacial spasm.
Document the specific muscles treated and the dosage of botulinum toxin used.
Otolaryngologists and neurologists should ensure proper coding based on the treatment plan.
The primary cause is often irritation or compression of the facial nerve, typically due to vascular issues or tumors.
Diagnosis is primarily clinical, based on the characteristic symptoms, and may include EMG to assess muscle activity.
Treatment options include botulinum toxin injections and, in severe cases, surgical intervention.
