ICD-10-CM Code Y92.243: City hall as the place of occurrence of the external cause

ICD-10-CM code Y92.243 identifies a city hall as the place where an external cause of morbidity occurred. This active terminology concept is a finding classified under public administrative buildings. It provides supplemental location context for injuries or health conditions and is not a principal diagnosis. 1 3 4

Plain-language overview

Code Y92.243 is an active terminology concept representing a city hall as the location where an external cause of morbidity occurred, giving healthcare providers supplemental context about an injury or health event. 1 3

What this code represents

The code Y92.243 represents a finding that falls under the parent concept Y92.24, which identifies a public administrative building as the place of occurrence of the external cause. 1

External cause codes provide supplementary information detailing how an injury occurred, the intent, the place of occurrence, and the patient status at the time of the injury. 3 6

Coding details

External cause codes are never coded as the primary or principal diagnosis, and they are inappropriate to assign if the cause is already included within another code's description. 4

Place of occurrence codes do not have seventh characters and are typically reported only on the initial encounter for treatment, sequenced after other external cause codes. 3

Documentation considerations

Coders may assign external cause codes only when documented, and they should not code an unspecified place of occurrence unless facility policy dictates otherwise. 3

When reporting external causes, there should be one place of occurrence code, one activity code, and one status code unless there is a new injury being documented. 4

What the sources add

A terminology record establishes the code hierarchy and active status, while a federal alert lists Y92.243 alongside other diagnosis codes within a document addressing excluded ICD-10-CM diagnoses. 1 2
