Code Description

ICD-10 V43.4 is a billable code used to indicate a diagnosis of person boarding or alighting a car injured in collision with car, pick-up truck or van.

Key Diagnostic Point:

The ICD-10 code V43.4 is used to classify injuries sustained by individuals who are boarding or alighting from a vehicle, specifically in the context of a collision with another car, pick-up truck, or van. This code is particularly relevant in cases where pedestrians or passengers are struck during the process of entering or exiting a vehicle. Clinical scenarios may include a person being hit by a moving vehicle while stepping off a curb or a passenger being injured as their vehicle is struck by another vehicle while they are in the process of exiting. Accurate coding of this scenario is crucial for understanding the circumstances surrounding the injury, which can inform public health initiatives aimed at reducing such incidents. Documentation should include details about the circumstances of the injury, the type of vehicle involved, and the actions of the injured party at the time of the incident.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Determining the exact moment of injury (boarding vs. alighting)
  • Identifying the type of vehicle involved in the collision
  • Differentiating between pedestrian and passenger injuries
  • Understanding the context of the collision (e.g., traffic conditions)

Audit Risk Factors

  • Inadequate documentation of the circumstances leading to the injury
  • Misclassification of the type of vehicle involved
  • Failure to specify whether the individual was a pedestrian or passenger
  • Lack of clarity on the actions of the injured person at the time of the incident

Specialty Focus

Medical Specialties

Emergency Medicine

Documentation Requirements

Emergency departments must document the mechanism of injury, including the type of vehicle involved and the actions of the patient at the time of injury.

Common Clinical Scenarios

Patients presenting with injuries after being struck by a vehicle while boarding or alighting, including fractures, contusions, or lacerations.

Billing Considerations

Emergency providers should ensure that the narrative of the injury is clear and detailed to support accurate coding.

Trauma Surgery

Documentation Requirements

Trauma documentation should include a detailed account of the injury mechanism, including the speed of the vehicle and the impact force.

Common Clinical Scenarios

Trauma cases involving significant injuries from vehicle collisions, requiring surgical intervention.

Billing Considerations

Trauma surgeons should collaborate with coders to ensure that all relevant details are captured for accurate coding.

Coding Guidelines

Inclusion Criteria

Use V43.4 When
  • According to ICD
  • 10 coding guidelines, external cause codes should be used in conjunction with the appropriate injury codes
  • It is essential to report the external cause code to provide context for the injury and to follow the guidelines for sequencing these codes correctly

Exclusion Criteria

Clinical Scenario

Used for patients presenting with injuries from vehicle collisions.

Documentation Requirements

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

Specialty Considerations

Emergency medicine providers should ensure that the visit is well-documented to support the coding of both the visit and the injury.

ICD-10 Impact

Diagnostic & Documentation Impact

Enhanced Specificity

ICD-10 Improvements

The transition to ICD-10 has allowed for more specific coding of external causes of injuries, including those related to vehicle collisions. This specificity aids in better tracking of injury patterns and can inform public health initiatives aimed at reducing such incidents.

ICD-9 vs ICD-10

The transition to ICD-10 has allowed for more specific coding of external causes of injuries, including those related to vehicle collisions. This specificity aids in better tracking of injury patterns and can inform public health initiatives aimed at reducing such incidents.

Reimbursement & Billing Impact

The transition to ICD-10 has allowed for more specific coding of external causes of injuries, including those related to vehicle collisions. This specificity aids in better tracking of injury patterns and can inform public health initiatives aimed at reducing such incidents.
