State road as the place of occurrence of the external cause

This code indicates that an external cause of injury or poisoning occurred on a state-maintained road. It specifies the general location of the incident, differentiating it from other types of roadways or public areas.

Apply this code when documentation clearly states the incident, such as a motor vehicle accident, pedestrian strike, or other external cause, took place on a state highway or state route. This is crucial for accurately identifying the environmental context of the injury.

• Ensure documentation explicitly mentions a "state road," "state highway," or "state route."
• Do not use for local streets, county roads, or interstates unless specifically designated as a state route.
• This code is always a secondary code, used in conjunction with an external cause code (V00-Y99).
