G54 is a non-billable ICD-10-CM category code for nerve root and plexus disorders, so it cannot be submitted on claims. Use a more specific code from this category instead, such as G54.0, G54.1, G54.2, and G54.3.

Specific Coding for Nerve root and plexus disordersOverview

Non-specific codes like G54 require more characters. Use one of these billable codes instead:

  • Use G54.0 for Brachial plexus disorders

  • Use G54.1 for Lumbosacral plexus disorders

  • Use G54.2 for Cervical root disorders, not elsewhere classified

  • Use G54.3 for Thoracic root disorders, not elsewhere classified

  • Use G54.4 for Lumbosacral root disorders, not elsewhere classified

  • Use G54.5 for Neuralgic amyotrophy

  • Use G54.6 for Phantom limb syndrome with pain

  • Use G54.7 for Phantom limb syndrome without pain

  • Use G54.8 for Other nerve root and plexus disorders

  • Use G54.9 for Nerve root and plexus disorder, unspecified

Instructional NotesGuidance

Instructions from the official ICD-10-CM Tabular List that apply to G54: its own notes plus those printed at block G50-G59 and Chapter 6. A note printed at a category, block or chapter applies to every code under it.

Excludes1

Not coded here: the excluded code is never reported together with this one, unless the two conditions are unrelated.

On G54 itself
  • current traumatic nerve root and plexus disorders - see nerve injury by body region
  • intervertebral disc disorders (M50-M51)
  • neuralgia or neuritis NOS (M79.2)
  • neuritis or radiculitis brachial NOS (M54.13)
  • neuritis or radiculitis lumbar NOS (M54.16)
  • neuritis or radiculitis lumbosacral NOS (M54.17)
  • neuritis or radiculitis thoracic NOS (M54.14)
  • radiculitis NOS (M54.10)
  • radiculopathy NOS (M54.10)
  • spondylosis (M47.-)
From Block G50-G59 Nerve, nerve root and plexus disorders applies to 106 codes
  • current traumatic nerve, nerve root and plexus disorders - see Injury, nerve by body region
  • neuralgia NOS (M79.2)
  • neuritis NOS (M79.2)
  • peripheral neuritis in pregnancy (O26.82-)
  • radiculitis NOS (M54.1-)

Excludes2

Not included here: the excluded condition is not part of this code, but a patient may have both, so both codes may be reported.

From Chapter 6 (G00-G99) Diseases of the nervous system applies to 700 codes
  • certain conditions originating in the perinatal period (P04-P96)
  • certain infectious and parasitic diseases (A00-B99)
  • complications of pregnancy, childbirth and the puerperium (O00-O9A)
  • congenital malformations, deformations, and chromosomal abnormalities (Q00-Q99)
  • endocrine, nutritional and metabolic diseases (E00-E88)
  • injury, poisoning and certain other consequences of external causes (S00-T88)
  • neoplasms (C00-D49)
  • symptoms, signs and abnormal clinical and laboratory findings, not elsewhere classified (R00-R94)

Peripheral Nerve Disorders

Nerves are like wires that carry messages back and forth between your brain and your body. Your peripheral nerves branch off from your brain and spinal cord and connect to all parts of your body, including your muscles and organs.

Questions About G54Overview

What is the ICD-10 code for nerve root and plexus disorders?

G54 is the ICD-10-CM category for nerve root and plexus disorders, but it is a non-billable header: claims need a more specific code from this category, listed on this page.

Is G54 (Nerve root and plexus disorders) a billable code?

No. This is a category header that groups the codes for nerve root and plexus disorders, and headers cannot be submitted on claims. Claims for nerve root and plexus disorders need a more specific code from this category, such as G54.0, G54.1, and G54.2.

Can G54 be reported with M79.2?

Not as a rule. The Excludes1 note on G54 lists "neuralgia or neuritis NOS (M79.2)". An Excludes1 note means the excluded code is never reported together with this one; the only exception is when the two conditions are unrelated to each other (Official Guidelines, Section I.A.12.a).
