Version 2021 Billable Code

Valid for Submission

G83.4 is a billable code used to specify a medical diagnosis of cauda equina syndrome. The code is valid for the fiscal year 2021 for the submission of HIPAA-covered transactions. The ICD-10-CM code G83.4 might also be used to specify conditions or terms like cauda equina syndrome, cauda equina syndrome not affecting bladder, cauda equina syndrome with cord bladder, cauda equina syndrome with neurogenic bladder, cauda equina syndrome with painless urinary retention, cauda equina syndrome without neurogenic bladder, etc

Tabular List of Diseases and Injuries

The Tabular List of Diseases and Injuries is a list of ICD-10 codes, organized "head to toe" into chapters and sections with guidance for inclusions, exclusions, descriptions and more. The following references are applicable to the code G83.4:

Inclusion Terms

Inclusion Terms
These terms are the conditions for which that code is to be used. The terms may be synonyms of the code title, or, in the case of "other specified" codes, the terms are a list of the various conditions assigned to that code. The inclusion terms are not necessarily exhaustive. Additional terms found only in the Alphabetic Index may also be assigned to a code.
  • Neurogenic bladder due to cauda equina syndrome

Type 1 Excludes

Type 1 Excludes
A type 1 excludes note is a pure excludes note. It means "NOT CODED HERE!" An Excludes1 note indicates that the code excluded should never be used at the same time as the code above the Excludes1 note. An Excludes1 is used when two conditions cannot occur together, such as a congenital form versus an acquired form of the same condition.

Index to Diseases and Injuries

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

  • Numbness
  • Pain
  • Burning or tingling
  • Muscle weakness
  • Sensitivity to touch

Treatment aims to treat any underlying problem, reduce pain and control symptoms.
