Disorder of facial nerve, unspecified. A disorder characterized by involvement of the facial nerve (seventh cranial nerve). A non-neoplastic or neoplastic disorder affecting the facial nerve (seventh cranial nerve). Diseases of the facial nerve or nuclei. Pontine disorders may affect the facial nuclei or nerve fascicle.
The 2021 edition of ICD-10-CM G51.9 became effective on October 1, 2020. This is the American ICD-10-CM version of G51.9 - other international versions of ICD-10 G51.9 may differ. A disorder characterized by involvement of the facial nerve (seventh cranial nerve).
Facial nerve synkinesis ICD-10-CM G51.8 is grouped within Diagnostic Related Group (s) (MS-DRG v38.0): 073 Cranial and peripheral nerve disorders with mcc 074 Cranial and peripheral nerve disorders without mcc

The facial nucleus is divided into a dorsal and ventral region. It contains the cell bodies of the facial nerve lower motor neurons (LMN). The dorsal region supplies innervation of the muscles of the upper face, whereas neurons in the ventral region innervate muscles of the lower face.
ICD-10-CM Code for Bell's palsy G51. 0.
The facial nerve is the seventh cranial nerve. It contains the motor, sensory, and parasympathetic (secretomotor) nerve fibers, which provide innervation to many areas of the head and neck region.
Facial nerve disorders occur when the nerve that controls facial movement and expression is damaged. They can occur as the result of a variety of factors. Viral infections, strokes, trauma, surgery, and tumors can all cause facial paralysis or weakness.
Bell's palsy is also known as acute peripheral facial palsy of unknown cause. It can occur at any age. The exact cause is unknown. Experts think it's caused by swelling and inflammation of the nerve that controls the muscles on one side of the face. It could be caused by a reaction that occurs after a viral infection.
1 - Atypical facial pain. G50. 1 - Atypical facial pain is a topic covered in the ICD-10-CM.
The facial muscles are innervated peripherally (infranuclear innervation) by the ipsilateral 7th cranial nerve and centrally (supranuclear innervation) by the contralateral cerebral cortex. Central innervation tends to be bilateral for the upper face (eg, forehead muscles) and unilateral for the lower face.
The facial nerve performs these motor (movement) and sensory functions: Controls the muscles that make your facial expressions. Controls muscle in your inner ear that moderates loudness of sound.
The five terminal branches of the facial nerve–the temporal, zygomatic, buccal, marginal mandibular, and cervical branches–are closely anatomically related to the parotid gland: they emerge from the parotid gland's upper, anterior, and lower borders.
In Bell's palsy there is inflammation around the facial nerve and this pressure causes facial paralysis on the affected side. Facial nerve palsy is the most common acute condition involving only one nerve, with Bell's palsy being the most common cause of acute facial paralysis.
Peripheral facial nerve palsy is diagnosed upon the clinical presentation with weakness of all facial nerve branches, drooping of the brow, incomplete lid closure, drooping of the corner of the mouth, impaired closure of the mouth, dry eye, hyperacusis, impaired taste, or pain around the ear.
The facial nerve exits the base of the skull at the stylomastoid foramen, which is an opening in the bone located near the base of the ear.
G51.9 is a billable ICD code used to specify a diagnosis of disorder of facial nerve, unspecified. A 'billable code' is detailed enough to be used to specify a medical diagnosis.
Cranial nerve disease is an impaired functioning of one of the twelve cranial nerves. Although it could theoretically be considered a mononeuropathy, it is not considered as such under MeSH .
There are more than 100 kinds of peripheral nerve disorders. They can affect one nerve or many nerves. Some are the result of other diseases, like diabetic nerve problems. Others, like guillain-barre syndrome, happen after a virus infection.
A non-neoplastic or neoplastic disorder that affects the peripheral nervous system. Diseases of the peripheral nerves external to the brain and spinal cord, which includes diseases of the nerve roots, ganglia, plexi, autonomic nerves, sensory nerves, and motor nerves. Your peripheral nerves are the ones outside your brain and spinal cord.
Your peripheral nerves are the ones outside your brain and spinal cord. Like static on a telephone line, peripheral nerve disorders distort or interrupt the messages between the brain and the rest of the body. There are more than 100 kinds of peripheral nerve disorders. They can affect one nerve or many nerves.
Approximate Synonyms. Neuropathy (nerve damage), peripheral. Peripheral nerve disease. Clinical Information. A nerve problem that causes pain, numbness, tingling, swelling, or muscle weakness in different parts of the body. It usually begins in the hands or feet and gets worse over time.
