S04.891A is an initial encounter code, includes a 7th character and should be used while the patient is receiving active treatment for a condition like injury of other cranial nerves right side. According to ICD-10-CM Guidelines an "initial encounter" doesn't necessarily means "initial visit".

The appropriate 7th character codes should also be used even if the patient delayed seeking treatment for a condition.

- Injury of pneumogastric nerve
- Injury of right hypoglossal nerve
- Injury of right vagus nerve

The approximate mapping means there is not an exact match between the ICD-10 code and the ICD-9 code and the mapped code is not a precise representation of the original code.
Information for Patients
Peripheral Nerve Disorders
Also called: Neuritis, Peripheral neuritis, Peripheral neuropathy
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.
