Nerve root and plexus disorders (G54) ICD-10-CM
The G54 code range covers nerve root and plexus disorders with 11 ICD-10-CM diagnosis codes. 10 of them are billable and valid for claim submission in fiscal year 2027, and the category headers group them but cannot themselves be billed.
Type 1 Excludes
A type 1 excludes note is a pure excludes note. It means "NOT CODED HERE!" An Excludes1 note indicates that the code excluded should never be used at the same time as the code above the Excludes1 note. An Excludes1 is used when two conditions cannot occur together, such as a congenital form versus an acquired form of the same condition.

Clinical Terms in This Code Range
Definitions from the National Library of Medicine for conditions coded in the G54 range.
Brachial Plexus Neuritis
A syndrome associated with inflammation of the BRACHIAL PLEXUS. Clinical features include severe pain in the shoulder region which may be accompanied by MUSCLE WEAKNESS and loss of sensation in the upper extremity. This condition may be associated with VIRUS DISEASES; IMMUNIZATION; SURGERY; heroin use (see HEROIN DEPENDENCE); and other conditions. The term brachial neuralgia generally refers to pain associated with brachial plexus injury. (From Adams et al., Principles of Neurology, 6th ed, pp1355-6)
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)
About the G54 Code Range
Problems involving nerve roots or plexuses appear here, along with neuralgic amyotrophy and phantom limb syndrome.
The plexus codes separate brachial disorders (G54.0) from lumbosacral disorders (G54.1). The root codes distinguish cervical (G54.2), thoracic (G54.3) and lumbosacral (G54.4) disorders.
G54.5 identifies neuralgic amyotrophy. Phantom limb syndrome is separated by whether pain is present: G54.6 with pain and G54.7 without pain. The remaining codes identify other or unspecified nerve root and plexus disorders.
Questions About This Page
How many billable codes are in the G54 range?
Of the 11 codes in this range, 10 are billable and valid for claim submission from October 1, 2026 through September 30, 2027. Category header codes group them but cannot be reported on claims.
What does the G54 range classify?
The range classifies nerve root and plexus disorders. Each code links to its own reference page with billing status, MS-DRG grouping, coding notes, and clinical information.
