Valid for Submission
G50.9 is a billable diagnosis code used to specify a medical diagnosis of disorder of trigeminal nerve, unspecified. The code G50.9 is valid during the fiscal year 2022 from October 01, 2021 through September 30, 2022 for the submission of HIPAA-covered transactions.
The ICD-10-CM code G50.9 might also be used to specify conditions or terms like disorder of left trigeminal nerve, disorder of right trigeminal nerve, fifth cranial nerve abnormal, idiopathic trigeminal neuropathy, ophthalmic nerve disorder , paratrigeminal syndrome, etc.
Unspecified diagnosis codes like G50.9 are acceptable when clinical information is unknown or not available about a particular condition. Although a more specific code is preferable, unspecified codes should be used when such codes most accurately reflect what is known about a patient's condition. Specific diagnosis codes should not be used if not supported by the patient's medical record.

Information for Patients
Peripheral Nerve Disorders
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. Some are the result of other diseases, like diabetic nerve problems. Others, like Guillain-Barre syndrome, happen after a virus infection. Still others are from nerve compression, like carpal tunnel syndrome or thoracic outlet syndrome. In some cases, like complex regional pain syndrome and brachial plexus injuries, the problem begins after an injury. Some people are born with peripheral nerve disorders.
Symptoms often start gradually, and then get worse. They include
- Burning or tingling
- Muscle weakness
- Sensitivity to touch
Treatment aims to treat any underlying problem, reduce pain and control symptoms.
