Code Description

ICD-10 G83.34 is a billable code used to indicate a diagnosis of monoplegia, unspecified affecting left nondominant side.

Key Diagnostic Point:

Monoplegia refers to paralysis affecting a single limb, in this case, the left nondominant side of the body. This condition can arise from various neurological disorders, including cerebral palsy, stroke, or traumatic brain injury. In individuals with cerebral palsy, monoplegia may result from damage to the brain during development, leading to motor function impairment in one limb. The left nondominant side typically refers to the side of the body that is not primarily used for tasks requiring fine motor skills, which can affect the patient's ability to perform daily activities. Patients may experience weakness, reduced coordination, and difficulties with mobility, which can significantly impact their quality of life. Rehabilitation strategies often include physical therapy, occupational therapy, and assistive devices to enhance mobility and independence. Understanding the underlying cause of monoplegia is crucial for effective treatment and management, as it can vary widely among patients.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Variability in documentation of monoplegia versus other types of paralysis.
  • Differentiating between monoplegia and hemiplegia or other paralysis types.
  • Need for precise clinical details to support the diagnosis.
  • Potential overlap with other neurological conditions.

Audit Risk Factors

  • Inadequate documentation of the specific limb affected.
  • Failure to specify the underlying cause of monoplegia.
  • Misclassification of the condition as hemiplegia or paraplegia.
  • Lack of supporting clinical evidence for the diagnosis.

Documentation Requirements

Detailed neurological examination findings, including motor function assessments.

Common Clinical Scenarios

Patients with stroke, traumatic brain injury, or cerebral palsy presenting with unilateral weakness.

Billing Considerations

Ensure clarity in the documentation of the affected side and limb, and the underlying cause of the condition.

Physical Medicine and Rehabilitation

Coding Guidelines

Inclusion Criteria

Use G83.34 When
  • According to ICD
  • 10 coding guidelines, G83
  • 34 should be used when monoplegia is confirmed and the affected side is specified
  • It is important to document the underlying cause, as this can influence treatment and management strategies

Diagnostic & Documentation Impact

Enhanced Specificity

ICD-10 Improvements

The transition to ICD-10 has allowed for more specific coding of conditions like monoplegia, improving the accuracy of diagnoses and treatment plans. This specificity helps in better resource allocation and management of care.

ICD-9 vs ICD-10

The transition to ICD-10 has allowed for more specific coding of conditions like monoplegia, improving the accuracy of diagnoses and treatment plans. This specificity helps in better resource allocation and management of care.

Reimbursement & Billing Impact

Frequently Asked Questions

What is the difference between monoplegia and hemiplegia?

Monoplegia refers to paralysis affecting a single limb, while hemiplegia involves paralysis of one side of the body, affecting both limbs on that side.
