Other disorders of facial nerve

Billable Code

| ICD-10 from 2011 - 2016

G51.8 is a billable ICD code used to specify a diagnosis of other disorders of facial nerve. A 'billable code' is detailed enough to be used to specify a medical diagnosis.

The ICD code G518 is used to code Parry-Romberg syndrome

Parry–Romberg syndrome (also known as progressive hemifacial atrophy) is a rare neurocutaneous syndrome characterized by progressive shrinkage and degeneration of the tissues beneath the skin, usually on only one side of the face (hemifacial atrophy) but occasionally extending to other parts of the body. An autoimmune mechanism is suspected, and the syndrome may be a variant of localized scleroderma, but the precise etiology and pathogenesis of this acquired disorder remains unknown. It has been reported in the literature as a consequence of sympathectomy. The syndrome has a higher prevalence in females and typically appears between 5 – 15 years of age.
