Bus as the place of occurrence of the external cause

This code indicates that a bus was the specific location where an injury or other adverse event occurred. It identifies the physical environment of the incident, rather than the mechanism of injury itself. This information is crucial for understanding the circumstances surrounding an external cause.

This code is used when documenting an injury or condition that happened on or within a bus, regardless of whether the bus was stationary or in motion. Examples include a fall inside a bus, an assault on a bus, or an injury sustained during a bus accident. It is always a secondary code, accompanying a primary code for the external cause and the nature of the injury.

• Always assign this code as a secondary code to an external cause code (e.g., V-codes, W-codes, X-codes).
• Ensure the documentation clearly specifies the incident occurred on or in a bus.
• Do not use this code if the injury occurred near a bus but not directly on it (e.g., hit by a bus while on the sidewalk).
