Code Description

ICD-10 G83.1 is a billable code used to indicate a diagnosis of monoplegia of lower limb.

Key Diagnostic Point:

Monoplegia of the lower limb refers to a condition characterized by paralysis affecting only one leg. This condition can arise from various neurological disorders, including cerebral palsy, stroke, traumatic brain injury, or spinal cord injury. In cases of cerebral palsy, monoplegia may result from damage to the brain during development, leading to motor function impairment in one limb. Patients may exhibit weakness, reduced muscle tone, and impaired coordination in the affected leg, which can significantly impact mobility and daily activities. Rehabilitation strategies often include physical therapy to improve strength and function, as well as adaptive devices to enhance mobility. The prognosis varies depending on the underlying cause and the extent of neurological damage, with some individuals achieving significant improvements while others may experience persistent limitations. Accurate coding of monoplegia is crucial for appropriate treatment planning and resource allocation in healthcare settings.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Differentiating between monoplegia and other forms of paralysis (e.g., hemiplegia, paraplegia)
  • Identifying the underlying cause of monoplegia for accurate coding
  • Variability in clinical presentation and severity among patients
  • Need for comprehensive documentation to support the diagnosis

Audit Risk Factors

  • Inadequate documentation of the cause of monoplegia
  • Failure to specify laterality (right or left limb affected)
  • Misclassification of the type of paralysis
  • Lack of supporting clinical evidence for the diagnosis

Specialty Focus

Medical Specialties

Neurology

Documentation Requirements

Detailed neurological examination findings, imaging results, and history of the presenting condition.

Common Clinical Scenarios

Patients presenting with unilateral weakness post-stroke or traumatic brain injury.

Billing Considerations

Ensure that the neurological assessment clearly indicates the extent and cause of monoplegia.

Physical Medicine and Rehabilitation

Documentation Requirements

Functional assessments, therapy progress notes, and treatment plans.

Common Clinical Scenarios

Rehabilitation of patients with monoplegia following neurological events.

Billing Considerations

Documenting the impact on mobility and daily living activities is crucial for coding.

Frequently Asked Questions

What is the difference between monoplegia and hemiplegia?

Monoplegia refers to paralysis affecting only one limb, while hemiplegia affects both limbs on one side of the body.
