Geniculate ganglionitis
ICD-10 G51.1 is a billable code used to indicate a diagnosis of geniculate ganglionitis.
Geniculate ganglionitis is an inflammatory condition affecting the geniculate ganglion, which is part of the facial nerve (cranial nerve VII). This condition is characterized by the inflammation of the ganglion, leading to symptoms such as facial pain, altered taste sensation, and potential facial weakness. The geniculate ganglion is located in the temporal bone and plays a crucial role in transmitting sensory information from the face and taste sensations from the anterior two-thirds of the tongue. Patients may present with unilateral symptoms, and the condition can be associated with viral infections, particularly herpes simplex virus. Diagnosis typically involves clinical evaluation, and may be supported by imaging studies or nerve conduction studies to assess the function of the facial nerve. Treatment often includes corticosteroids to reduce inflammation and manage symptoms. Understanding the underlying pathophysiology and clinical presentation is essential for accurate coding and management of this condition.
Detailed neurological examination findings, including sensory and motor function assessments.
Patients presenting with unilateral facial pain and sensory changes.
Documentation should clearly outline the neurological assessment and any imaging or nerve conduction studies performed.
Thorough history of symptoms, including onset, duration, and associated factors.
Patients with facial pain and taste disturbances, particularly post-viral infection.
Consideration of differential diagnoses such as Bell's palsy or other cranial nerve disorders.
Used to assess facial nerve function in patients with suspected geniculate ganglionitis.
Document the rationale for nerve conduction studies and findings.
Neurology specialists should ensure comprehensive documentation of nerve function assessments.
Common symptoms include unilateral facial pain, altered taste sensation, and potential facial weakness, often following a viral infection.
