Struck by falling object in cave-in, subsequent encounter

This code signifies an injury sustained when a patient was hit by debris due to a structural collapse, such as in a mine, trench, or building. It specifically applies to follow-up care for such an injury, not the initial treatment.

Use this code for any subsequent visits related to an injury initially caused by being struck by a falling object during a cave-in. This includes follow-up appointments for wound care, fracture management, or rehabilitation after the initial acute phase of treatment.

• Ensure the encounter is for follow-up care; initial encounters require the "A" seventh character.
• Verify the mechanism of injury specifically involves a falling object within a cave-in scenario.
• Always code the specific injury (e.g., fracture, contusion) in addition to this external cause code.
