Valid for Submission
S04.9XXD is a billable diagnosis code used to specify a medical diagnosis of injury of unspecified cranial nerve, subsequent encounter. The code S04.9XXD is valid during the fiscal year 2021 from October 01, 2020 through September 30, 2021 for the submission of HIPAA-covered transactions.
The ICD-10-CM code S04.9XXD might also be used to specify conditions or terms like avulsion of cranial nerve, chemical cranial nerve injury, complete division of cranial nerve, contusion of cranial nerve, cranial nerve compression , injuries of brain and cranial nerves with injuries of nerves and spinal cord at neck level, etc. The code is exempt from present on admission (POA) reporting for inpatient admissions to general acute care hospitals.
S04.9XXD is a subsequent encounter code, includes a 7th character and should be used after the patient has completed active treatment for a condition like injury of unspecified cranial nerve. According to ICD-10-CM Guidelines a "subsequent encounter" occurs when the patient is receiving routine care for the condition during the healing or recovery phase of treatment. Subsequent diagnosis codes are appropriate during the recovery phase, no matter how many times the patient has seen the provider for this condition. If the provider needs to adjust the patient's care plan due to a setback or other complication, the encounter becomes active again.
Unspecified diagnosis codes like S04.9XXD 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.
The appropriate 7th character is to be added to each code from block Injury of cranial nerve (S04). Use the following options for the aplicable episode of care:
- A - initial encounter
- D - subsequent encounter
- S - sequela
The following clinical terms are approximate synonyms or lay terms that might be used to identify the correct diagnosis code:
- Avulsion of cranial nerve
- Chemical cranial nerve injury
- Complete division of cranial nerve
- Contusion of cranial nerve
- Cranial nerve compression
- Injuries of brain and cranial nerves with injuries of nerves and spinal cord at neck level
- Injury of cranial nerve
- Injury of superficial nerves of head AND/OR neck
- Neuropathy due to ionizing radiation
- Partial division of cranial nerve
- Radiation injury of cranial nerve
- Thermal injury of cranial nerve
- Traction injury of cranial nerve

Convert S04.9XXD to ICD-9 Code
The General Equivalency Mapping (GEM) crosswalk indicates an approximate mapping between the ICD-10 code S04.9XXD its ICD-9 equivalent. 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.
