Other paralytic syndromes (G83) ICD-10-CM
The G83 code range covers other paralytic syndromes with 29 ICD-10-CM diagnosis codes. 24 of them are billable and valid for claim submission in fiscal year 2027, and the category headers group them but cannot themselves be billed.

This note appears immediately under a three character code title to further define, or give examples of, the content of the category.
- This category is to be used only when the listed conditions are reported without further specification, or are stated to be old or longstanding but of unspecified cause. The category is also for use in multiple coding to identify these conditions resulting from any cause.

Clinical Terms in This Code Range
Definitions from the National Library of Medicine for conditions coded in the G83 range.
Anterior Cord Syndrome
A syndrome caused by occlusion or injury to the anterior spinal artery. It is typically characterized by an abrupt onset of pain followed by bilateral motor deficits at or below the level of the lesion, and alterations of pain and temperature sensations a few dermatomal segments below the level of the lesion.
Brown-Sequard Syndrome
A syndrome associated with injury to the lateral half of the spinal cord. The condition is characterized by the following clinical features (which are found below the level of the lesion): contralateral hemisensory anesthesia to pain and temperature, ipsilateral loss of propioception, and ipsilateral motor paralysis. Tactile sensation is generally spared. (From Adams et al., Principles of Neurology, 6th ed, p162).
Cauda Equina Syndrome
Compressive lesion affecting the nerve roots of the CAUDA EQUINA (e.g., compression, herniation, inflammation, rupture, or stenosis), which controls the function of the bladder and bowel. Symptoms may include neurological dysfunction of bladder or bowels, loss of sexual sensation and altered sensation or paralysis in the lower extremities.
Locked-In State
A rare neurologic disorder caused by an insult to the brainstem. It is characterized by quadriplegia, bulbar palsy, and sensory loss. However, level of consciousness, cognition, hearing, eye movements and blinking may be preserved.
Monoplegia
Paralysis that affects one limb.
Paralysis
A general term most often used to describe severe or complete loss of muscle strength due to motor system disease from the level of the cerebral cortex to the muscle fiber. This term may also occasionally refer to a loss of sensory function. (From Adams et al., Principles of Neurology, 6th ed, p45)
Posterior Cord Syndrome
A syndrome caused by insult to the posterior columns of the spinal cord and resulting in impairments of proprioception, vibration, and fine touch. Typical presenting signs and symptoms may include sensory ataxia, dizziness, unsteady gait, and frequent falls.
Todd's Paralysis
A neurological condition experienced by individuals with epilepsy, in which a seizure is followed by a brief period of temporary paralysis.
About the G83 Code Range
These paralytic syndromes include paralysis affecting the upper limbs or a single limb, as well as named syndromes.
G83.0 identifies diplegia of the upper limbs. Monoplegia, paralysis of one limb, is divided into lower limb (G83.1), upper limb (G83.2) and unspecified limb (G83.3). Each of these groups separates right from left, dominant from nondominant, and specified from unspecified side.
Other subdivisions identify named syndromes under G83.4, G83.5 and G83.8. G83.9 identifies an unspecified paralytic syndrome.
