Code Description

ICD-10 V56.4 is a billable code used to indicate a diagnosis of person boarding or alighting a pick-up truck or van injured in collision with other nonmotor vehicle.

Key Diagnostic Point:

The ICD-10 code V56.4 is used to classify injuries sustained by individuals who are boarding or alighting from a pick-up truck or van and are subsequently involved in a collision with a nonmotor vehicle, such as a bicycle, pedestrian, or animal. This code is particularly relevant in scenarios where the individual is in the process of entering or exiting the vehicle, which can increase the risk of injury due to the proximity to traffic and the dynamics of the collision. Clinical documentation should detail the circumstances of the incident, including the type of nonmotor vehicle involved, the speed of the vehicles, and the nature of the injuries sustained. Accurate coding is essential for understanding the epidemiology of such incidents and for implementing public health strategies aimed at reducing similar occurrences in the future.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Determining the exact circumstances of the injury (boarding vs. alighting)
  • Identifying the type of nonmotor vehicle involved in the collision
  • Documenting the mechanism of injury accurately
  • Differentiating between similar external cause codes

Audit Risk Factors

  • Inadequate documentation of the incident details
  • Misclassification of the type of vehicle involved
  • Failure to specify whether the person was boarding or alighting
  • Inconsistent coding practices across different healthcare settings

Specialty Focus

Medical Specialties

Emergency Medicine

Documentation Requirements

Emergency department notes should include a detailed account of the incident, including the patient's position relative to the vehicle and the nonmotor vehicle involved.

Common Clinical Scenarios

Patients presenting with injuries after being struck while boarding or alighting from a vehicle, often with fractures or soft tissue injuries.

Billing Considerations

Consideration of the patient's awareness of their surroundings and any contributing factors such as visibility or traffic conditions.

Trauma Surgery

Documentation Requirements

Trauma documentation must include a comprehensive assessment of injuries, mechanism of injury, and any surgical interventions performed.

Common Clinical Scenarios

Trauma cases involving significant injuries from collisions with nonmotor vehicles, requiring surgical intervention.

Billing Considerations

Attention to detail in documenting the mechanism of injury to support the severity of trauma and the need for surgical care.

Coding Guidelines

Inclusion Criteria

Use V56.4 When
  • According to the ICD
  • CM coding guidelines, external cause codes should be used in conjunction with the primary diagnosis code
  • It is essential to report the external cause code to provide context for the injury and to comply with reporting requirements

Exclusion Criteria

Do NOT use V56.4 When

Documentation Requirements

Documentation must support the level of service, including history, examination, and medical decision-making.

Specialty Considerations

Emergency medicine specialists should ensure that the external cause code is linked to the appropriate visit level.
