The characteristic of 'place of occurrence' external cause codes is that they describe where the injury took place. These codes are part of the ICD-10-CM coding system, specifically utilized to capture the external factors that can affect health. The 'place of occurrence' code provides detailed information about the specific location of the incident that caused the injury, whether it was at home, in a workplace, or during recreational activities. This information is crucial for public health purposes, enabling the analysis of injury patterns and helping in the development of strategies to prevent similar incidents.

In contrast, while a 7th character extension can be present in some external cause codes to provide additional details, it does not specifically relate to 'place of occurrence' codes. Similarly, the activity during the injury pertains more to another subset of codes that captures what was happening at the time of the incident rather than where it occurred. Lastly, not all health service encounters require the recording of external cause codes; they are specifically applicable when there is an injury or health event that warrants this type of documentation.
