Code Description

ICD-10 G83.32 is a billable code used to indicate a diagnosis of monoplegia, unspecified affecting left dominant side.

Key Diagnostic Point:

Monoplegia refers to paralysis affecting a single limb, in this case, the left side of a person who is left-dominant. This condition can arise from various neurological disorders, including cerebral palsy, stroke, traumatic brain injury, or multiple sclerosis. In individuals with cerebral palsy, monoplegia may result from abnormal brain development or injury during early development, leading to motor function impairment. Patients may experience significant mobility challenges, affecting their ability to perform daily activities. The left dominant side being affected can lead to difficulties in tasks that require fine motor skills, such as writing or using utensils. Rehabilitation strategies often include physical therapy, occupational therapy, and assistive devices to enhance mobility and independence. Understanding the underlying cause of the monoplegia is crucial for effective management and treatment planning.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Variability in documentation of left-sided dominance
  • Differentiation from other types of paralysis (e.g., hemiplegia)
  • Potential overlap with other neurological conditions
  • Need for precise clinical details to support coding

Audit Risk Factors

  • Inadequate documentation of left dominance
  • Failure to specify the cause of monoplegia
  • Misclassification of the type of paralysis
  • Lack of supporting clinical evidence for the diagnosis

Specialty Focus

Neurology

Documentation Requirements

Detailed neurological examination findings, including motor function assessments and diagnostic imaging results.

Common Clinical Scenarios

Patients presenting with sudden onset of weakness or paralysis, follow-up visits for rehabilitation progress.

Billing Considerations

Ensure clear documentation of the neurological assessment and any imaging studies that support the diagnosis.

Physical Medicine and Rehabilitation

Documentation Requirements

Comprehensive rehabilitation plans, therapy progress notes, and functional assessments.

Common Clinical Scenarios

Patients undergoing rehabilitation for mobility impairments, assessments for assistive devices.

Billing Considerations

Document specific functional limitations and goals for therapy to support the need for ongoing rehabilitation.

Frequently Asked Questions

What is the difference between monoplegia and hemiplegia?

Monoplegia refers to paralysis affecting a single limb, while hemiplegia affects both the upper and lower limbs on one side of the body.
