G54.4 — Lumbosacral root disorders, not elsewhere classified

BillableUnspecified

Is G54.4 billable?

Yes, but G54.4 is an unspecified code. G54.4 is a valid, billable ICD-10-CM code for encounters from October 1, 2026 through September 30, 2027. However, G54.4 is an unspecified or catch-all code. Payers apply additional scrutiny to unspecified codes and many deny them when the medical record supports a more specific option, so check the documentation before selecting G54.4 — the more specific alternatives are listed below.

Which MS-DRGs does G54.4 group to?

How is G54.4 listed in the Alphabetic Index?

These are the routes through the Alphabetic Index that lead to G54.4. They show the wording a clinician may have documented, which often differs from the Tabular description.

  • Disorder › lumbosacral › rootNEC (of)
  • Lesion › lumbosacral › rootNEC (s) (nontraumatic)

Excludes1 — never code together — inherited from G50-G59

The conditions below can never be reported together with G54.4 on the same claim. An Excludes1 note means the two conditions cannot occur in the same patient, so reporting both is a coding error.

  • 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-)

Excludes1 — never code together — inherited from G54

The conditions below can never be reported together with G54.4 on the same claim. An Excludes1 note means the two conditions cannot occur in the same patient, so reporting both is a coding error.

  • 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.-)

Excludes2 — not included here — inherited from Chapter 6

The conditions below are not part of G54.4, but a patient may have both at the same time. When documentation supports it, G54.4 and the excluded code may both be reported.

  • 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)

How long has G54.4 existed?

G54.4 has been in ICD-10-CM since at least FY2016, the earliest fiscal year on record here.

Derived from the official order files for FY2016–FY2026. FY2017 and FY2020 publish no order file, so those years are not covered.
