Code Description

ICD-10 V42.1 is a billable code used to indicate a diagnosis of car passenger injured in collision with two- or three-wheeled motor vehicle in nontraffic accident.

Key Diagnostic Point:

This code is used to classify injuries sustained by a car passenger involved in a collision with a two- or three-wheeled motor vehicle, such as a motorcycle or scooter, occurring in a nontraffic accident setting. Nontraffic accidents may include incidents occurring in private property, parking lots, or other areas not designated as public roadways. The injuries can range from minor to severe, depending on the nature of the collision and the protective measures in place (e.g., seatbelts, airbags). Accurate coding is essential for understanding the epidemiology of such injuries, guiding public health initiatives, and ensuring appropriate resource allocation for trauma care. Documentation should clearly indicate the circumstances of the accident, the type of vehicles involved, and the nature of the injuries sustained to support the use of this code.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Determining the exact nature of the accident (nontraffic vs. traffic)
  • Identifying the type of vehicles involved (two- or three-wheeled motor vehicles)
  • Documenting the passenger's role and injuries accurately
  • Differentiating between similar external cause codes

Audit Risk Factors

  • Inadequate documentation of the accident's circumstances
  • Misclassification of the accident type (traffic vs. nontraffic)
  • Failure to specify the type of motor vehicle involved
  • Inconsistent coding practices across different healthcare settings

Specialty Focus

Medical Specialties

Emergency Medicine

Documentation Requirements

Emergency departments must document the mechanism of injury, the type of vehicles involved, and the patient's injuries in detail.

Common Clinical Scenarios

Patients presenting with injuries from collisions in parking lots or private property.

Billing Considerations

Emergency physicians should ensure that the documentation reflects the nontraffic nature of the accident to support accurate coding.

Trauma Surgery

Documentation Requirements

Trauma surgeons need to document the specifics of the injury, including the mechanism of injury and any surgical interventions performed.

Common Clinical Scenarios

Trauma cases involving significant injuries from motorcycle collisions.

Billing Considerations

Trauma documentation should include details about the patient's condition upon arrival and any pre-existing conditions that may affect recovery.

Coding Guidelines

Inclusion Criteria

Use V42.1 When
  • Coders should refer to the ICD
  • CM Official Guidelines for Coding and Reporting, particularly sections on external causes of morbidity
  • Accurate coding requires a thorough understanding of the circumstances surrounding the injury and the vehicles involved
