Instructional NotesGuidance
Instructions from the official ICD-10-CM Tabular List that apply to G54.0: its own notes plus those printed at G54, block G50-G59, and Chapter 6. A note printed at a category, block or chapter applies to every code under it.
Applicable To
Conditions this code is used for: synonyms of the title or, for "other specified" codes, the conditions assigned to it. The list is not exhaustive.
- Thoracic outlet syndrome
Excludes1
Not coded here: the excluded code is never reported together with this one, unless the two conditions are unrelated.
- 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: the excluded condition is not part of this code, but a patient may have both, so both codes may 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)

Clinical InformationClinical
Brachial Plexus Neuropathies
diseases of the cervical (and first thoracic) roots, nerve trunks, cords, and peripheral nerve components of the brachial plexus. clinical manifestations include regional pain, paresthesia; muscle weakness, and decreased sensation (hypesthesia) in the upper extremity. these disorders may be associated with trauma (including birth injuries); thoracic outlet syndrome; neoplasms; neuritis; radiotherapy; and other conditions. (from adams et al., principles of neurology, 6th ed, pp1351-2)
Patient EducationClinical
Brachial Plexus Injuries
The brachial plexus is a network of nerves that sends signals from the spine to the shoulder, arm, and hand. Damage to the brachial plexus can cause symptoms such as:

Questions About G54.0Overview
What is the ICD-10 code for brachial plexus disorders?
The ICD-10-CM code for brachial plexus disorders is G54.0 (sometimes written as G540). It is billable on HIPAA-covered claims from October 1, 2026 through September 30, 2027.
Is G54.0 (Nerve root and plexus disorders) a billable code?
Yes. This is a billable ICD-10-CM code, specific enough to report brachial plexus disorders on HIPAA-covered claims from October 1, 2026 through September 30, 2027.
What MS-DRG does G54.0 group to?
When brachial plexus disorders is the principal diagnosis on an inpatient stay, it groups to MS-DRG 74, 73, with relative weights from 1.0172 to 1.5773 depending on complications. Higher weights mean higher Medicare reimbursement.
Can G54.0 be reported with M79.2?
Not as a rule. The Excludes1 note at G54, which applies to G54.0, 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).
What is the ICD-9 equivalent of G54.0?
Under the General Equivalence Mappings, brachial plexus disorders converts to ICD-9-CM 353.0 (brachial plexus lesions). The mapping is approximate, so confirm the match fits the documentation.
