Code Description

ICD-10 V46 is a billable code used to indicate a diagnosis of car occupant injured in collision with other nonmotor vehicle.

Key Diagnostic Point:

The ICD-10 code V46 is used to classify injuries sustained by car occupants involved in collisions with nonmotor vehicles, such as bicycles, pedestrians, or animals. This code is essential for accurately documenting the circumstances surrounding the injury, which is crucial for public health data, insurance claims, and epidemiological studies. When coding for V46, it is important to specify the nature of the collision and the type of nonmotor vehicle involved, as this can influence treatment decisions and resource allocation. Accurate coding helps in understanding the patterns of injuries related to traffic incidents, which can inform preventive measures and policy-making. Documentation should include details about the event, such as the location, time, and contributing factors, to ensure comprehensive data capture and analysis.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Need for precise documentation of the type of nonmotor vehicle involved.
  • Variability in injury severity based on the nature of the collision.
  • Potential for multiple external cause codes to be applicable.
  • Requirement to differentiate between similar codes for accurate reporting.

Audit Risk Factors

  • Inadequate documentation of the type of nonmotor vehicle involved.
  • Failure to capture all relevant external cause codes.
  • Misclassification of the incident type leading to incorrect coding.
  • Inconsistent use of codes across different healthcare settings.

Specialty Focus

Emergency Medicine

Documentation Requirements

Emergency department notes must clearly describe the incident, including the type of nonmotor vehicle and the mechanism of injury.

Common Clinical Scenarios

A patient presents with injuries after being struck by a bicycle while crossing the street.

Billing Considerations

Ensure that all relevant details of the incident are documented to support the use of V46.

Trauma Surgery

Documentation Requirements

Trauma registries require detailed descriptions of the injury mechanism and the type of nonmotor vehicle involved.

Common Clinical Scenarios

A patient suffers fractures after a collision with a pedestrian while driving.

Billing Considerations

Accurate coding is critical for trauma outcomes analysis and resource allocation.
