Code Description

ICD-10 V21.4 is a billable code used to indicate a diagnosis of motorcycle driver injured in collision with pedal cycle in traffic accident.

Key Diagnostic Point:

The ICD-10 code V21.4 is used to classify injuries sustained by motorcycle drivers involved in collisions with pedal cycles during traffic accidents. This code is essential for capturing the external cause of morbidity and mortality related to traffic incidents, specifically highlighting the dynamics between motorized and non-motorized vehicles. In clinical settings, accurate coding of such incidents is crucial for understanding injury patterns, resource allocation, and public health interventions. Documentation should include details about the circumstances of the accident, the type of injuries sustained, and any contributing factors such as weather conditions or road conditions. This code is particularly relevant in emergency medicine and trauma surgery, where timely and precise coding can influence treatment protocols and outcomes.

  • Need for precise documentation of the accident circumstances
  • Differentiation between types of vehicles involved
  • Potential for multiple injuries requiring additional codes
  • Variability in state reporting requirements

Audit Risk Factors

  • Inadequate documentation of the accident details
  • Misclassification of the type of vehicle involved
  • Failure to capture all injuries sustained
  • Inconsistent coding practices across providers

Emergency Medicine

Documentation Requirements

Emergency departments must document the mechanism of injury, including the type of vehicles involved and the circumstances of the collision.

Common Clinical Scenarios

Patients presenting with trauma from motorcycle accidents involving pedal cyclists, including fractures, lacerations, and head injuries.

Billing Considerations

Consideration of helmet use and protective gear, as these factors can influence injury severity.

Trauma Surgery

Documentation Requirements

Trauma documentation should include detailed descriptions of injuries, surgical interventions, and the mechanism of injury.

Common Clinical Scenarios

Trauma cases involving surgical intervention due to severe injuries from motorcycle-pedal cycle collisions.

Billing Considerations

Assessment of injury patterns specific to motorcycle accidents, including potential for polytrauma.

Coding Guidelines

Inclusion Criteria

Use V21.4 When
  • According to ICD
  • 10 coding guidelines, external cause codes should be used in conjunction with the corresponding injury codes
  • It is important to report the external cause code in the secondary position to the primary diagnosis code for the injury sustained
