Code Description

ICD-10 V21.91 is a billable code used to indicate a diagnosis of unspecified electric (assisted) bicycle rider injured in collision with pedal cycle in traffic accident.

Key Diagnostic Point:

The code V21.91 is used to classify injuries sustained by riders of electric (assisted) bicycles involved in collisions with pedal bicycles during traffic accidents. This code is essential for capturing the specifics of incidents involving electric bicycles, which have become increasingly popular in urban areas. The injuries can range from minor abrasions to severe trauma, depending on the speed of the collision and the protective gear worn by the rider. Accurate coding is crucial for public health data collection, injury prevention strategies, and resource allocation for emergency services. It is important to document the circumstances of the accident, including the location, time, and contributing factors, to ensure comprehensive data for analysis and future prevention efforts.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Variability in documentation of electric bicycle specifications
  • Differentiation between types of bicycles involved in the collision
  • Need for precise details about the accident circumstances
  • Potential for overlapping codes with other traffic-related injuries

Audit Risk Factors

  • Inadequate documentation of the type of bicycle involved
  • Failure to specify the circumstances of the collision
  • Misclassification of the injury type or severity
  • Inconsistent use of external cause codes across providers

Specialty Focus

Medical Specialties

Emergency Medicine

Documentation Requirements

Emergency departments must document the mechanism of injury, including details about the collision, rider's protective gear, and any pre-existing conditions.

Common Clinical Scenarios

Common scenarios include collisions at intersections, accidents involving multiple vehicles, and falls resulting from sudden stops.

Billing Considerations

Consideration should be given to the rider's age, experience level, and any contributing factors such as weather conditions or visibility.

Trauma Surgery

Documentation Requirements

Trauma documentation must include a detailed account of the injury mechanism, anatomical location of injuries, and any surgical interventions performed.

Common Clinical Scenarios

Trauma cases may involve severe head injuries, fractures, or soft tissue injuries resulting from high-impact collisions.

Billing Considerations

Trauma surgeons should be aware of the potential for multiple injuries and the need for comprehensive coding to reflect the full extent of trauma.
