G58 is a non-billable ICD-10-CM category code for other mononeuropathies, so it cannot be submitted on claims. Use a more specific code from this category instead, such as G58.0, G58.7, G58.8, and G58.9.

Specific Coding for Other mononeuropathiesOverview

Non-specific codes like G58 require more characters. Use one of these billable codes instead:

  • Use G58.0 for Intercostal neuropathy

  • Use G58.7 for Mononeuritis multiplex

  • Use G58.8 for Other specified mononeuropathies

  • Use G58.9 for Mononeuropathy, unspecified

Instructional NotesGuidance

Instructions from the official ICD-10-CM Tabular List that apply to G58: 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.

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)

Patient EducationClinical

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 G58Overview

What is the ICD-10 code for other mononeuropathies?

G58 is the ICD-10-CM category for other mononeuropathies, but it is a non-billable header: claims need a more specific code from this category, listed on this page.

Is G58 (Other mononeuropathies) a billable code?

No. This is a category header that groups the codes for other mononeuropathies, and headers cannot be submitted on claims. Claims for other mononeuropathies need a more specific code from this category, such as G58.0, G58.7, and G58.8.

Can G58 be reported with M79.2?

Not as a rule. The Excludes1 note at block G50-G59, which applies to G58, lists "neuralgia 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).
