Also known as
Bell's palsy
Facial paralysis caused by inflammation of the facial nerve.

Inflammation of the geniculate ganglion affecting the facial nerve.
Other facial nerve disorders
Facial paralysis from other specified facial nerve conditions.
Facial nerve disorder, unspecified
Facial paralysis of unspecified cause involving the facial nerve.
Follow this step-by-step guide to choose the correct ICD-10 code.
Is the facial paralysis traumatic?
Yes
Code the underlying traumatic injury causing the facial paralysis (e.g., S00-T88).
No
Is the paralysis related to Ramsay Hunt syndrome?
When to use each related code
| Description |
|---|
| Sudden weakness or paralysis of facial muscles on one side. |
| Facial paralysis with ear pain, blisters, and rash, often caused by herpes zoster. |
| Facial paralysis caused by stroke, tumor, or trauma affecting the facial nerve. |
Missing or incorrect laterality specification (right, left, bilateral) for facial paralysis impacts reimbursement and data accuracy.
Coding Bell's Palsy with unspecified facial paralysis (G51.9) instead of the more specific code (G51.0) leads to underreporting.
Failure to code known underlying causes of facial paralysis, like Lyme disease or Ramsay Hunt syndrome, affects quality reporting and case mix index.
Q: What are the key differential diagnoses to consider when evaluating a patient presenting with acute onset unilateral facial paralysis, and how can I distinguish Bell's Palsy from stroke or Lyme disease?
A: When a patient presents with acute onset unilateral facial paralysis, it's crucial to differentiate Bell's Palsy from other serious conditions like stroke, Lyme disease, Ramsay Hunt syndrome, and tumors. While Bell's Palsy is the most common cause, a thorough assessment is necessary. Stroke typically involves additional neurological deficits such as arm or leg weakness, slurred speech, or vision changes. Lyme disease may present with other symptoms like a rash (erythema migrans), fever, headache, or joint pain. Ramsay Hunt syndrome often includes a painful vesicular rash in or around the ear. Specific diagnostic tests, including serology for Lyme disease, MRI for stroke or tumor suspicion, and electromyography and nerve conduction studies to assess facial nerve function, can help confirm the diagnosis and guide appropriate management. Consider implementing a standardized diagnostic approach for facial paralysis to ensure comprehensive evaluation and accurate differentiation. Explore how S10.AI can assist in streamlining your diagnostic process for facial paralysis.
Q: What are the evidence-based treatment options for Bell's Palsy, and when should corticosteroids like prednisone be initiated in the management of Bell's Palsy?
A: Current evidence-based treatment for Bell's Palsy strongly recommends corticosteroid therapy, specifically prednisone, within 72 hours of symptom onset. This intervention is effective in reducing inflammation and improving the chances of complete recovery. Antiviral medications, such as acyclovir, are sometimes used in conjunction with corticosteroids, particularly in cases with severe paralysis or suspicion of herpes simplex virus reactivation (Ramsay Hunt syndrome). Eye care is also crucial, as incomplete eyelid closure can lead to corneal damage. Protecting the eye with lubricating drops, ointments, and an eye patch during sleep is essential. Consider implementing early initiation of corticosteroids within the 72-hour window to optimize patient outcomes. Learn more about emerging research in Bell's Palsy management and supportive therapies like physical therapy to enhance recovery.
Patient presents with acute onset of unilateral facial paralysis, consistent with a clinical diagnosis of Bell's Palsy (Facial Nerve Palsy, Idiopathic Facial Paralysis). Symptoms include facial drooping, weakness on one side of the face, inability to close the eye on the affected side, difficulty smiling, frowning, and raising the eyebrow. Onset was reported as [sudden/gradual] approximately [number] [days/weeks] ago. Patient denies any history of trauma, recent infection, or other neurological symptoms. Physical examination reveals [describe specific findings, e.g., loss of nasolabial fold, inability to fully close eyelid, drooping of the corner of the mouth]. House-Brackmann Facial Nerve Grading Scale score is documented as [score]. Differential diagnosis includes Ramsay Hunt syndrome, stroke, and Lyme disease. Based on the clinical presentation and negative findings for alternative diagnoses, the diagnosis of Bell's Palsy is most likely. Treatment plan includes corticosteroids (e.g., prednisone) to reduce inflammation and improve facial nerve function. Eye protection measures, such as artificial tears and eye patching, are prescribed to prevent corneal complications due to incomplete eyelid closure. Patient education regarding Bell's Palsy prognosis, potential complications, and follow-up care was provided. ICD-10 code G51.0 (Bell's palsy) is assigned. Patient will follow up in [timeframe] for reassessment of facial nerve function and to monitor for any complications.
