Legal intervnt involving unsp explosv, bystand injured, subs

This code signifies an injury sustained by an individual who was a bystander during a legal intervention involving an unspecified explosive device. The injury is a result of the explosive and occurred during a subsequent encounter for care related to this specific incident.

Apply this code when a patient presents for follow-up treatment (e.g., wound care, physical therapy, psychological evaluation) for injuries sustained as an uninvolved party during a law enforcement or military operation that utilized an explosive. This code is appropriate for any encounter after the initial treatment for the injury.

• Always assign an external cause code for the specific injury sustained.
• Ensure the "D" seventh character is used only for subsequent encounters, not the initial treatment.
• Verify documentation clearly states the patient was a bystander and the event involved legal intervention with an explosive.
