Code Description

ICD-10 V28.21 is a billable code used to indicate a diagnosis of unspecified electric (assisted) bicycle rider injured in noncollision transport accident in nontraffic accident.

Key Diagnostic Point:

The V28.21 code is used to classify injuries sustained by riders of electric (assisted) bicycles in noncollision transport accidents that occur outside of traffic scenarios. This code is particularly relevant in situations where the rider may have fallen, collided with an object, or experienced mechanical failure while riding in a non-traffic environment, such as a park or private property. The injuries can range from minor abrasions to severe trauma, depending on the circumstances of the accident. Accurate coding is essential for tracking injury patterns, understanding the risks associated with electric bicycles, and facilitating appropriate public health interventions. Documentation should clearly outline the nature of the accident, the environment in which it occurred, and the specifics of the injuries sustained to ensure proper coding and billing.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Ambiguity in defining 'noncollision' accidents
  • Variability in documentation practices across providers
  • Potential overlap with other external cause codes
  • Need for detailed accident descriptions to support coding

Audit Risk Factors

  • Insufficient documentation of the accident context
  • Misclassification of the accident type (traffic vs. nontraffic)
  • Failure to specify the type of electric bicycle involved
  • Inadequate detail on the nature of the injuries

Specialty Focus

Medical Specialties

Emergency Medicine

Documentation Requirements

Emergency department notes should include a detailed account of the incident, including the mechanism of injury, location, and any contributing factors.

Common Clinical Scenarios

Patients presenting with injuries from falls while riding electric bicycles in parks or residential areas.

Billing Considerations

Ensure that the documentation specifies that the accident was nontraffic-related to avoid misclassification.

Trauma Surgery

Documentation Requirements

Trauma assessments must detail the mechanism of injury, including the type of electric bicycle and the circumstances leading to the injury.

Common Clinical Scenarios

Trauma cases involving fractures or head injuries from falls off electric bicycles.

Billing Considerations

Consider the potential for multiple injuries and ensure all are documented to support comprehensive coding.

Coding Guidelines

Inclusion Criteria

Use V28.21 When
  • Follow the ICD
  • CM coding guidelines for external causes of morbidity, ensuring that the code is used in conjunction with the appropriate injury codes
  • Document the circumstances of the accident clearly to support the use of V28

Exclusion Criteria

Do NOT use V28.21 When
No specific exclusions found.
