Paraplegia (paraparesis) and quadriplegia (quadriparesis) (G82) ICD-10-CM
The G82 code range covers paraplegia (paraparesis) and quadriplegia (quadriparesis) with 11 ICD-10-CM diagnosis codes. 8 of them are billable and valid for claim submission in fiscal year 2026, 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.
- 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 G82 range.
Central Nervous System Diseases
Diseases of any component of the brain (including the cerebral hemispheres, diencephalon, brain stem, and cerebellum) or the spinal cord.
Paraparesis
Mild to moderate loss of bilateral lower extremity motor function, which may be a manifestation of SPINAL CORD DISEASES; PERIPHERAL NERVOUS SYSTEM DISEASES; MUSCULAR DISEASES; INTRACRANIAL HYPERTENSION; parasagittal brain lesions; and other conditions.
Paraparesis, Spastic
Mild or moderate loss of motor function accompanied by spasticity in the lower extremities. This condition is a manifestation of CENTRAL NERVOUS SYSTEM DISEASES that cause injury to the motor cortex or descending motor pathways.
Paraparesis, Tropical Spastic
A subacute paralytic myeloneuropathy occurring endemically in tropical areas such as the Caribbean, Colombia, India, and Africa, as well as in the southwestern region of Japan; associated with infection by HUMAN T-CELL LEUKEMIA VIRUS I. Clinical manifestations include a slowly progressive spastic weakness of the legs, increased reflexes, Babinski signs, incontinence, and loss of vibratory and position sensation. On pathologic examination inflammatory, demyelination, and necrotic lesions may be found in the spinal cord. (Adams et al., Principles of Neurology, 6th ed, p1239)
Paraplegia
Severe or complete loss of motor function in the lower extremities and lower portions of the trunk. This condition is most often associated with SPINAL CORD DISEASES, although BRAIN DISEASES; PERIPHERAL NERVOUS SYSTEM DISEASES; NEUROMUSCULAR DISEASES; and MUSCULAR DISEASES may also cause bilateral leg weakness.
Quadriplegia
Severe or complete loss of motor function in all four limbs which may result from BRAIN DISEASES; SPINAL CORD DISEASES; PERIPHERAL NERVOUS SYSTEM DISEASES; NEUROMUSCULAR DISEASES; or rarely MUSCULAR DISEASES. The locked-in syndrome is characterized by quadriplegia in combination with cranial muscle paralysis. Consciousness is spared and the only retained voluntary motor activity may be limited eye movements. This condition is usually caused by a lesion in the upper BRAIN STEM which injures the descending cortico-spinal and cortico-bulbar tracts.
Spastic Paraplegia, Hereditary
A group of inherited diseases that share similar phenotypes but are genetically diverse. Different genetic loci for autosomal recessive, autosomal dominant, and x-linked forms of hereditary spastic paraplegia have been identified. Clinically, patients present with slowly progressive distal limb weakness and lower extremity spasticity. Peripheral sensory neurons may be affected in the later stages of the disease. (J Neurol Neurosurg Psychiatry 1998 Jan;64(1):61-6; Curr Opin Neurol 1997 Aug;10(4):313-8)
About the G82 Code Range
ICD-10 codes in the G82 group specifically cover paraplegia and quadriplegia conditions. These codes are essential for identifying different forms and severities of paralysis affecting either the lower limbs (paraplegia) or all four limbs (quadriplegia).
The broad G82 category includes both paraplegia and quadriplegia. For paraplegia, codes like G82.20 indicate unspecified paralysis of the lower limbs, with synonyms such as paraparesis and spinal paraparesis helping clarify coding choices. More precise distinctions include complete (G82.21) and incomplete (G82.22) paraplegia. Quadriplegia codes start with G82.5 and extend to specify injury level and completeness of paralysis. For example, G82.50 covers unspecified quadriplegia, while G82.51 to G82.54 delineate complete or incomplete quadriplegia at cervical spine levels C1 to C7. Synonyms like tetraplegia and tetraparesis assist coders in matching clinical terms to the correct ICD-10 code. These codes capture paralysis severity and location, providing vital detail for accurate diagnosis and treatment tracking in healthcare settings.

How many billable codes are in the G82 range?
Of the 11 codes in this range, 8 are billable and valid for claim submission from October 1, 2025 through September 30, 2026. Category header codes group them but cannot be reported on claims.
What does the G82 range classify?
The range classifies paraplegia (paraparesis) and quadriplegia (quadriparesis). Each code links to its own reference page with billing status, MS-DRG grouping, coding notes, and clinical information.
