    ICD-10-CM Code For Hemiplegia And Hemiparesis: Group Overview

    The International Classification of Diseases, Tenth Revision, Clinical Modification (ICD-10-CM) code group G81 includes diagnoses for hemiplegia and hemiparesis, covering paralysis or weakness of one side of the body due to neurologic injury such as stroke, trauma, or other central nervous system disorders. These ICD-10-CM diagnosis codes are used to document functional impairment, sidedness, and severity when capturing motor deficits and related clinical complexity. Accurate coding within the ICD-10-CM G81 group supports proper claim adjudication and complete clinical documentation for appropriate reimbursement.

    ICD-10-CM G81: Hemiplegia And Hemiparesis Overview

    The ICD-10-CM G81 group includes diagnoses for hemiplegia and hemiparesis, characterized by paralysis or weakness of one side of the body. These conditions typically result from neurologic injury to the brain or spinal pathways and affect motor function and daily activities. Accurate coding matters for appropriate reimbursement and reflecting the complexity of care needs.

    When to Use

    Use codes from this group when documenting unilateral motor paralysis or weakness caused by neurologic insult such as cerebrovascular accident or brain injury. Select the code that specifies laterality and any additional descriptors required by the code set to accurately reflect the patients condition.

    Typical Clinical Scenarios

    • A 72-year-old man presents to the emergency department after an acute ischemic stroke with sudden onset right-sided weakness and facial droop noticed this morning. Neurologic exam demonstrates dense right hemiplegia affecting the arm and leg with intact consciousness; imaging confirms a left middle cerebral artery infarct, so an acute paralytic syndrome affecting the right side is documented and coded. Typical codes: G81.11, G81.14
    • A 9-year-old child with established spastic cerebral palsy is seen in outpatient neurology for progressive asymmetric weakness of the left upper and lower extremities causing gait disturbance and need for orthotic adjustments. This is an ongoing chronic hemiparesis related to the underlying developmental motor disorder, so a persistent unilateral motor deficit code is assigned for longitudinal care and therapy planning. Typical codes: G81.01, G81.04
    • A 58-year-old woman with a remote stroke history presents to a rehabilitation clinic with new falls and worsening ambulation due to residual right-sided weakness compounded by muscle contractures and chronic pain. The visit addresses late effects and complications of prior paralytic injury contributing to disability; a code denoting sequelae or late effect hemiparesis/hemiplegia is used to capture the chronic residual deficit. Typical codes: G81.91, G81.94
