Code Description

ICD-10 G83.21 is a billable code used to indicate a diagnosis of monoplegia of upper limb affecting right dominant side.

Key Diagnostic Point:

Monoplegia of the upper limb affecting the right dominant side is a neurological condition characterized by the paralysis of the right arm, which is typically the dominant limb for most individuals. This condition can arise from various etiologies, including cerebral palsy, traumatic brain injury, stroke, or other neurological disorders. In patients with cerebral palsy, monoplegia may result from abnormal brain development or injury during early development, leading to motor function impairments. The affected individual may experience significant mobility impairments, impacting their ability to perform daily activities, such as dressing, eating, and writing. Rehabilitation strategies often include physical therapy, occupational therapy, and assistive devices to enhance functional independence. The prognosis varies depending on the underlying cause and the extent of neurological damage, with early intervention being crucial for improving outcomes.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Differentiating between monoplegia and other forms of paralysis.
  • Identifying the underlying cause of the paralysis.
  • Documenting the patient's functional limitations accurately.
  • Understanding the implications of the patient's dominant side.

Audit Risk Factors

  • Inadequate documentation of the patient's dominant side.
  • Failure to specify the underlying cause of paralysis.
  • Misclassification of the type of paralysis.
  • Lack of evidence for the functional limitations reported.

Specialty Focus

Medical Specialties

Neurology

Documentation Requirements

Detailed neurological examination findings, including motor function assessments and any imaging studies.

Common Clinical Scenarios

Patients presenting with unilateral weakness following a stroke or traumatic brain injury.

Billing Considerations

Ensure that the documentation clearly states the affected side and the patient's dominant hand.

Physical Medicine and Rehabilitation

Documentation Requirements

Functional assessments, therapy progress notes, and treatment plans focusing on mobility and independence.

Common Clinical Scenarios

Rehabilitation of patients with cerebral palsy or post-stroke recovery.

Billing Considerations

Document the impact of therapy on the patient's daily activities and quality of life.

Coding Guidelines

Inclusion Criteria

Use G83.21 When
  • According to ICD
  • 10 coding guidelines, G83
  • 21 should be used when there is clear documentation of monoplegia affecting the right upper limb, with emphasis on the patient's dominant side

Exclusion Criteria

Do NOT use G83.21 When
  • Exclusion criteria include conditions that do not specifically affect the upper limb or are not classified as monoplegia

Frequently Asked Questions

What is the difference between monoplegia and hemiplegia?

Monoplegia refers to paralysis of a single limb, while hemiplegia involves paralysis of one side of the body, affecting both the arm and leg.
