Code Description

ICD-10 G83.31 is a billable code used to indicate a diagnosis of monoplegia, unspecified affecting right dominant side.

Key Diagnostic Point:

Monoplegia refers to paralysis affecting a single limb, in this case, the right side of a person who is right-hand dominant. 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 motor cortex or pathways that control movement. The impact on mobility can vary significantly, with some individuals experiencing mild weakness while others may have complete loss of function in the affected limb. 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 influence the prognosis and rehabilitation approach. Accurate coding is essential for appropriate reimbursement and to reflect the patient's condition in medical records.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Variability in clinical presentation and severity of monoplegia
  • Differentiation from other types of paralysis (e.g., hemiplegia, paraplegia)
  • Need for comprehensive documentation of the patient's functional status
  • Potential overlap with other neurological conditions

Audit Risk Factors

  • Insufficient documentation of the cause of monoplegia
  • Failure to specify the affected limb in clinical notes
  • Inconsistent use of terminology in patient records
  • Lack of evidence for the dominant side designation

Specialty Focus

Medical Specialties

Neurology

Documentation Requirements

Detailed neurological examination findings, including motor function assessment and any imaging results.

Common Clinical Scenarios

Patients presenting with sudden onset of weakness, chronic conditions like cerebral palsy, or post-stroke rehabilitation.

Billing Considerations

Ensure that the documentation clearly states the dominant side and the extent of paralysis.

Physical Medicine and Rehabilitation

Documentation Requirements

Comprehensive rehabilitation plans, progress notes, and functional assessments.

Common Clinical Scenarios

Rehabilitation following stroke, traumatic brain injury, or congenital conditions like cerebral palsy.

Billing Considerations

Document the patient's functional goals and progress to support the need for ongoing therapy.

Coding Guidelines

Inclusion Criteria

Use G83.31 When
  • Follow the official ICD
  • CM coding guidelines, ensuring that the code is used only when the monoplegia is confirmed and documented

Exclusion Criteria

Do NOT use G83.31 When
  • Exclude conditions that may indicate a different type of paralysis

Frequently Asked Questions

What is the difference between monoplegia and hemiplegia?

Monoplegia refers to paralysis affecting a single limb, while hemiplegia affects both limbs on one side of the body. Accurate coding requires understanding the specific type of paralysis.
