Code Description

ICD-10 V21.39 is a billable code used to indicate a diagnosis of person boarding or alighting other motorcycle injured in collision with pedal cycle.

Key Diagnostic Point:

This code is used to classify injuries sustained by individuals who are boarding or alighting from a motorcycle and are involved in a collision with a pedal cycle (bicycle). Such incidents can occur in various environments, including urban areas where motorcycle and bicycle traffic is common. The injuries can range from minor abrasions to severe trauma, depending on the speed of the vehicles involved and the circumstances of the collision. Accurate coding of this incident is crucial for understanding the epidemiology of motorcycle-related injuries and for implementing public health interventions aimed at reducing such accidents. Documentation should include details about the circumstances of the incident, the type of motorcycle and bicycle involved, and the nature of the injuries sustained.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Determining the correct external cause code based on the specifics of the incident.
  • Differentiating between injuries sustained while boarding versus alighting.
  • Understanding the context of the collision (e.g., urban vs. rural settings).
  • Accurate documentation of the type of motorcycle and pedal cycle involved.

Audit Risk Factors

  • Inadequate documentation of the circumstances leading to the injury.
  • Misclassification of the type of vehicle involved in the collision.
  • Failure to specify whether the individual 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 details about the motorcycle and pedal cycle, and the patient's condition upon arrival.

Common Clinical Scenarios

Patients presenting with fractures, lacerations, or contusions after a motorcycle-bicycle collision.

Billing Considerations

Consideration of the patient's history, including helmet use and protective gear, which may influence injury severity.

Trauma Surgery

Documentation Requirements

Trauma assessments must include detailed descriptions of the injuries sustained and the mechanism of injury to support coding.

Common Clinical Scenarios

Trauma cases involving significant injuries such as head trauma or orthopedic injuries from motorcycle collisions.

Billing Considerations

Documentation should reflect the severity of injuries and any surgical interventions performed.

Coding Guidelines

Inclusion Criteria

Use V21.39 When
  • Follow the ICD
  • CM guidelines for external cause codes, ensuring that the code is used in conjunction with the appropriate injury codes
  • The external cause code should be reported in the secondary position after the primary diagnosis code
