Building under construction as place

This code indicates that an injury or adverse event occurred within the confines of a building that was actively undergoing construction at the time of the incident. It specifies the physical environment as a construction site within a building, rather than an open-air construction zone.

Apply this code when a patient presents with an injury sustained while on the premises of a building that is clearly identified as being under construction. This includes incidents like falls from scaffolding inside a building, being struck by falling objects within a building frame, or injuries from equipment used in an indoor construction setting.

• Always use this code as a secondary code to specify the place of occurrence, following the primary external cause code (e.g., W01, W13).
• Ensure documentation explicitly states the building was "under construction" at the time of the incident, not merely being renovated or repaired.
• Distinguish from codes for construction sites in general (Y92.6) if the incident specifically occurred within a building structure.
