Code Description

ICD-10 V49.29 is a billable code used to indicate a diagnosis of unspecified car occupant injured in collision with other motor vehicles in nontraffic accident.

Key Diagnostic Point:

The ICD-10 code V49.29 is used to classify injuries sustained by car occupants involved in collisions with other motor vehicles that occur outside of traditional traffic scenarios. This may include incidents such as collisions in parking lots, private property, or during vehicle maneuvers that do not occur on public roadways. The code is essential for capturing the external causes of morbidity and mortality related to vehicular accidents, which can inform public health initiatives and safety regulations. Accurate coding is crucial for understanding the epidemiology of such injuries, guiding preventive measures, and allocating resources effectively. Documentation should specify the circumstances of the accident, including location and nature of the collision, to ensure appropriate use of this code.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Ambiguity in defining 'nontraffic' accidents
  • Variability in documentation quality from different healthcare providers
  • Need for precise details about the accident circumstances
  • Potential overlap with other external cause codes

Audit Risk Factors

  • Insufficient documentation of the accident's circumstances
  • Misclassification of traffic vs. nontraffic incidents
  • Failure to specify the type of vehicle involved
  • Inadequate linkage between diagnosis and external cause code

Specialty Focus

Medical Specialties

Emergency Medicine

Documentation Requirements

Emergency department notes must clearly describe the mechanism of injury, location of the accident, and any relevant patient history.

Common Clinical Scenarios

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

Billing Considerations

Ensure that the documentation explicitly states the nontraffic nature of the incident to avoid confusion with traffic-related codes.

Trauma Surgery

Documentation Requirements

Trauma registries should include detailed descriptions of the injury mechanism and circumstances surrounding the event.

Common Clinical Scenarios

Trauma cases involving patients injured in vehicle collisions while on private property.

Billing Considerations

Accurate coding is critical for trauma data analysis and resource allocation; ensure all details are captured.

Coding Guidelines

Inclusion Criteria

Use V49.29 When
  • Follow the official ICD
  • CM coding guidelines, ensuring that external cause codes are sequenced appropriately after the primary diagnosis code
  • Document the specific circumstances of the injury to support the use of V49

Exclusion Criteria

Do NOT use V49.29 When
No specific exclusions found.
