Code Description

ICD-10 V43.42 is a billable code used to indicate a diagnosis of person boarding or alighting a car injured in collision with other type car.

Key Diagnostic Point:

The ICD-10 code V43.42 is used to classify injuries sustained by individuals who are boarding or alighting from a vehicle and are subsequently involved in a collision with another vehicle. This scenario typically occurs in urban settings where pedestrian traffic is high, and vehicles are in close proximity to sidewalks or boarding areas. The injuries can range from minor abrasions to severe trauma, depending on the speed of the vehicles involved and the circumstances of the incident. Accurate coding of this event is crucial for understanding the epidemiology of traffic-related injuries and for implementing public health interventions aimed at reducing such incidents. Documentation should include details about the circumstances of the injury, the type of vehicles involved, and the location of the incident to ensure proper coding and analysis of external causes of morbidity.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Determining the exact circumstances of the injury (boarding vs. alighting)
  • Identifying the type of vehicles involved in the collision
  • Differentiating between pedestrian injuries and those sustained by vehicle occupants
  • Ensuring accurate documentation of the location and context of the incident

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 among different coders

Specialty Focus

Medical Specialties

Emergency Medicine

Documentation Requirements

Emergency department notes should clearly document the mechanism of injury, including whether the patient was boarding or alighting from the vehicle.

Common Clinical Scenarios

Patients presenting with trauma after being struck while boarding a bus or exiting a taxi.

Billing Considerations

Emergency physicians should ensure that the narrative in the medical record supports the use of V43.42, particularly in high-traffic areas.

Trauma Surgery

Documentation Requirements

Trauma documentation must include detailed descriptions of the injury mechanism and the patient's position relative to the vehicle.

Common Clinical Scenarios

Trauma cases involving pedestrians struck by vehicles while boarding or alighting.

Billing Considerations

Trauma surgeons should be aware of the potential for severe injuries and ensure that all relevant details are captured for accurate coding.

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 and analysis of injury patterns and public health initiatives.

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 and analysis of injury patterns and public health initiatives.

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 and analysis of injury patterns and public health initiatives.
