Postherpetic geniculate ganglionitis
ICD-10 B02.21 is a billable code used to indicate a diagnosis of postherpetic geniculate ganglionitis.
Postherpetic geniculate ganglionitis is a complication that arises following an outbreak of herpes zoster (shingles), which is caused by the reactivation of the varicella-zoster virus (VZV). This condition specifically affects the geniculate ganglion, a cluster of nerve cells located in the facial region. Patients typically present with severe pain, sensory disturbances, and sometimes motor deficits in the distribution of the facial nerve. The pain can be debilitating and is often described as burning or stabbing. The onset of postherpetic neuralgia (PHN) can occur after the resolution of the rash associated with shingles, leading to prolonged discomfort. Diagnosis is primarily clinical, based on the history of herpes zoster and the characteristic symptoms. Treatment may include antiviral medications, analgesics, and sometimes corticosteroids to reduce inflammation and pain. Vaccination against herpes zoster is recommended for older adults to prevent the occurrence of shingles and its complications, including postherpetic geniculate ganglionitis.
