Code Description

ICD-10 V21.3 is a billable code used to indicate a diagnosis of person boarding or alighting a motorcycle injured in collision with pedal cycle.

Key Diagnostic Point:

The ICD-10 code V21.3 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). This code captures the external cause of morbidity and mortality related to motorcycle accidents, specifically focusing on the circumstances surrounding the injury. Such incidents often occur in urban settings where traffic is dense, and the interaction between motorized and non-motorized vehicles is frequent. The injuries can range from minor abrasions to severe trauma, including fractures and head injuries, depending on the speed of the vehicles involved and the protective measures taken by the motorcyclist. Accurate coding of this incident is crucial for public health data, as it helps in understanding the patterns of motorcycle-related injuries and informs preventive measures and policy-making.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Determining the exact circumstances of the injury (boarding or alighting)
  • Differentiating between types of vehicles involved (motorcycle vs. pedal cycle)
  • Documenting the severity of injuries accurately
  • Understanding the context of the accident (urban vs. rural settings)

Audit Risk Factors

  • Inaccurate documentation of the circumstances leading to the injury
  • Failure to specify whether the individual was boarding or alighting
  • Misclassification of the type of vehicle involved
  • Inconsistent use of external cause codes in related claims
