Micromobility-related injuries involving devices such as e-bikes and e-scooters continue to increase across New York City. Accurate surveillance of these injuries remains challenging due to inconsistent clinical terminology, evolving device types, limited device specificity from ICD-10-CM codes, and limitations in traditional external datasets such as police crash reports. A pictogram originally developed at a single trauma center to improve documentation was expanded through a multi-center collaboration involving trauma centers, trauma registrars, EMS, and public health agencies. Simultaneously, the authors and colleagues developed ICD-10-CM code groupings related to micromobility injuries to standardize injury surveillance across sites and facilitate regional data sharing.

A multidisciplinary collaboration involving NYC trauma centers, EMS providers, New York City agencies that participate in the New York City Vision Zero initiative, and the New York State Department of Health worked to standardize micromobility injury identification practices.

A micromobility pictogram—a visual representation of micromobility device types—was collaboratively revised and implemented in trauma bays, documentation areas, trauma flow sheets, and select EMS documentation systems to standardize terminology used during patient encounters. Staff at participating institutions shared information on device types to include on the pictogram, ease of use, when and how to involve patients in using the pictogram, and more.

Concurrently, colleagues from city and state health departments collaborated with trauma center partners to develop a surveillance framework consisting of approximately 300 existing ICD-10-CM codes grouped into five categories: e-bike or similar rider, stand-up e-scooter rider, motorcyclist/ATV/off-road vehicle rider, pedal cyclist, and pedestrian struck by anyone riding a device listed in the prior four categories. NYC Health + Hospitals trauma centers began collecting and sharing data with the NYC Vision Zero initiative using the standardized framework, and additional trauma centers are preparing to join the surveillance effort.

Twelve of New York City’s 18 trauma centers were utilizing a pictogram as of January 2026, with additional centers beginning implementation following the dissemination of the updated standardized pictogram through the Regional Trauma Advisory Committee in June 2026. The collaboration established a shared framework for identifying and categorizing micromobility injuries across trauma systems. Standardized terminology improved consistency in clinical documentation and supported more accurate ICD-10-CM code selection by trauma registrars.

In 2025, the six participating NYC Health + Hospitals trauma centers identified 969 patients associated with micromobility-related ICD-10-CM codes using the standardized surveillance framework. The framework captured a broader range of micromobility-related injuries than traditional external datasets alone and supported regional data sharing between trauma centers and public health agencies.

Collaborative standardization of clinical terminology and ICD-10-CM code groupings may improve micromobility injury surveillance across trauma systems. Partnerships between trauma centers, EMS, and public health agencies can support the development of shared surveillance infrastructure in rapidly evolving injury areas and help inform future prevention strategies and public health interventions.
