ICD-10 Code G54 – Nerve root and plexus disorders (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code G54 – Nerve root and plexus disorders
What it is
G54 identifies disorders affecting spinal nerve roots or nerve plexuses. Use it for conditions where the problem involves nerve root or plexus function, rather than a single peripheral nerve.
Clinical signs
Clinical features vary; refer to documentation. Typical findings may include pain, numbness, tingling, weakness, or sensory loss in a nerve root or plexus distribution.
When to use this code
Use G54 when the provider documents a nerve root or plexus disorder without a more specific code. It may apply when symptoms and exam findings support radicular or plexus involvement. Check documentation for the exact site and cause, if stated.
Do not use for
Do not use this code for isolated peripheral nerve disorders, myopathies, or unspecified limb pain. If the record identifies a more specific diagnosis, code that condition instead.
Coding tip
Review the note for laterality, level, and named nerve root or plexus details before assigning G54.
